At 16:35, to create a new scene from the Ball object on new version of Godot (as the icon shown by Benjamin not exist anymore): right clic on the name of the object and in the menu which opened, select "Save branch as scene" ("Sauvegarde la branche comme scéne" in French)
Thank you! I spent twenty minutes searching on screen and through website documentations for it :D
Thank you!
Bump this plz
Pierre-Louis LAMBALLAIS you are the best person

If you are using a newer version of Godot, instead of writing:
var speed = get_linear_velocity().Length(),
write
var speed = linear_velocity.length()
For those people that might get an error saying "invalid get index 'type' (on base 'input event mouse motion')". Don't use that. Instead use "if event is InputEventMouseButton:". The rest is fine.
I couldn't get past this, thank you!
thanks!, this held me for a while
For those who are doing this with Godot 3.1. I've added some print commands, to see what the numbers are. Its a great way to see how Godot calculates its math. (Also explains why I didn't use the delta in the velocity variable)
extends RigidBody2D
class_name Ball
const SpeedUp = 10
const MaxSpeed = 300
func _ready():
set_physics_process(true)
func _physics_process(delta):
var bodies = get_colliding_bodies()
for body in bodies:
if body.is_in_group("Bricks"):
body.queue_free()
if body.get_name() == "Paddle":
var speed = get_linear_velocity().length()
var direction = position - body.get_node("Anchor").get_global_position()
var velocity = direction.normalized()*min(speed+SpeedUp, MaxSpeed)
set_linear_velocity(velocity)
print(delta)
print(speed)
print(direction)
print(velocity)
if position.y > get_viewport_rect().end.y:
print("Ball died.")
queue_free()
I added a print(" ")
to get a blank line between those groups of numbers.
you don't need to multiply delta by 100, what you should do is not apply delta when you calculate the new velocity. velocity is a unit that already includes time (ie pixels per second), so you're saying this is the new velocity, and the physics engine takes care of spreading that over the frames, you just have to provide the pixels per second value, not a pixels per frame (or tic) value
+pete275 Wait, the engine automatically applies delta to the velocity of a node? I've read through most of the documentation and I didn't see that in there. Can you show me where that is?
It might not be anywhere because it's implied in the word "velocity" :) Normally your approach is correct, because you're saying, every frame, "move this many pixels". So to figure out how many pixels you have to move, you do "direction_normal * speed * delta_time". "speed" in this case is a number of pixels per second, and delta time is how many seconds went by since the last frame (usually something like 0.016). But in this case you're not saying "move x pixels every frame", you're saying "this is your new velocity". Note that you only set the velocity when the ball hits the pad, not on every frame. So you set the velocity (in a unit of pixels per second), and from then on the engine will move the ball according to that velocity, until it hits another body that might modify its velocity. The relevant code is around body_2d_sw.cpp:560, where it multiplies the final integrated velocity by p_step, and applies the new matrix to the body
Interesting, thanks. :)
I hope I'm not too late but in Godot documentation for set_linear_speed says, and I quote: " DON’T SET THIS IN EVERY FRAME", and points to use _integrate_forces. Do you know how to implement this?
After that, +pete275 is right in the way common physics work, the delta multiplication trick goes with the position increment by speed*delta(time), should be used if want to set position hardcoded.
Note1: Godot documentation advises to don't hardcode the position because it could mess with the physics engine.
Note2: +HeartBeast by the way, your maths could be wrong: speed + SPEEDUP*delta isn't the same as (speed + SPEEDUP)*delta.
Thanks for the great tutorial and keep the awesome work.
Another way to see this is that: you were assigning a "displacemente = velocity * time" as the velocity.
At 21:16, if you're using Godot 3.0 later, replace
if event.type == InputEvent.MOUSE_BUTTON && event.is_pressed():
with
if event is InputEventMouseButton && event.pressed:
ur a GOAT, thank u.
ERROR: 28:26
"Invalid get index 'type' (on base: 'InputEventMouseMotion')"
SOLUTION:
if(event is InputEventMouseButton && event.is_pressed()): works
so 1 == 1 and 1 is int, '==' compares btw. values but 'is' gives if 1 is an integer
What exactly do we do, replace your line with the sugesstion?
Edit: Yep, do what this guy says and you are good to go
YOU LEGEND! Perfect solution to the exact error I was facing. I'm so proud of this community lol
@@ash7324 welcome
It feels good to finish a tutorial and have everything work. Even though this is from 2016 this comments and community still keep it up to date fixing anything that's changed and offering helpful advice. Thanks for the tutorial that still holds up.
Here is that article on Vector Math. I recommend reading it even if you don't plan on using Godot: docs.godotengine.org/en/latest/tutorials/vector_math.html
+HeartBeast Would you say that Godot is better than GM?
+Sebastián Roca Nope. I would say they are both good. I would use GM for certain types of games and Godot for certain types of games. What type of game do you want to build?
+HeartBeast I would like to build a 2d shooter like "Enter the Gungeon" or something similar, which one would be better?
+Sebastián Roca Personally I'd use GameMaker for that :)
HeartBeast many thanks! greetings from Argentina! :3
in Godot 4, the Position2d node is now the Marker2d node.
I am sooo blown away by how powerful, clean and organize godot is! the scene tab is insane, godot will make you feel unity being messy IMO (from unity before). Its really a great engine especially for 2d, i was aiming for 3d development, but 2d game play but i think its no longer necessary with godot :)
Great tutorial, and i know you are working on game maker tutorial, but please don't also give up with godot, you make mind-blowing tutorials, thanks!
Regards
Just a friendly reminder to spell out position instead of using pos if you're using a newer version of Godot.
I spelt all of them as position except one as pos by accident and I was wondering why it was crashing when the ball was colliding with things lol. 😂 anyways easy fix once I realised.
I have used first three parts of this tutorial with Godot 3.0, and ended up with slightly different code which is included below. Changes that I have made:
- "Mini Scenes" renamed to "Entities"
- instead of multiplying SPEEDUP and MAXSPEED by 100 times, I have just deleted ".normalized()" part from direction
########
# Ball.gd #
########
extends RigidBody2D
const SPEEDUP = 4
const MAXSPEED = 300
func _physics_process(delta):
var bodies = get_colliding_bodies()
for body in bodies:
if body.is_in_group("Bricks"):
body.queue_free()
if body.get("name") == "Paddle":
var speed = linear_velocity.length()
var direction = position - body.get_node("Ancor").global_position
var velocity = direction * min(speed + SPEEDUP * delta, MAXSPEED * delta)
linear_velocity = velocity
if position.y > get_viewport_rect().end.y:
queue_free()
##########
# Paddle.gd #
##########
extends KinematicBody2D
const BALL_SCENE = preload("res://Entities/Ball.tscn")
func _physics_process(delta):
var y = position.y
var x = get_viewport().get_mouse_position().x
position = Vector2(x,y)
func _input(event):
if event.is_action_pressed("click"):
var ball = BALL_SCENE.instance()
ball.position = position - Vector2(0, 16)
get_tree().root.add_child(ball)
did you delete the _ready function?
yes, it's not needed in 3.0
Thank you HeartBeast and djpeknuk.
I had to make one small change. In Paddle.gd, instead of "if event.is_action_pressed("click")" I had to use "if event.is_pressed()".
or --> if (event is InputEventMouseButton && event.pressed):
Deleting "normalized" will just create another problem because then it can have whatever magnitude while normalizing it makes sure that your speed will indeed be the one you set in the constant. The error that he made is that he multiplied the speed by delta when the Godot game engine takes care of that
Getting "Invalid get index 'type' on base: 'InputEventMouseMotion')." error?
if event.type == InputEvent.MOUSE_BUTTON && event.is_pressed():
does not work any more in Godot 3.0
I changed it to
if event is InputEventKey and event.get_scancode() == KEY_SPACE:
The documentation for Godot is awful, and I'm not smart enough to figure out how to do this with the mouse,
so this will have to do for now. It probably involves InputEventMouseButton
does anybody know what the .get_scancode() equivalent would be for InputEventMouseButton?
Edit:
OK I'm a smart pony after all :P
if event.type == InputEvent.MOUSE_BUTTON && event.is_pressed():
can simply be replace with
if event is InputEventMouseButton:
and this shiz will work now :D
Edit 2 Electric Boogaloo:
K the previous code results in 2 balls, one for click, and one for release, use this instead:
if event is InputEventMouseButton && event.is_pressed():
This game be sweet now.
Nonetheless, I'd wished that the Godot Docs were using example code with each method. It's written in a way that experts surely find quickly what they need to know. But for a game engine that strives to become a widely known and used product it still seems to target the wrong audience.
If it weren't for tutorials like those offered by Benjamin or a handful of others, we'd have to rely on those few instructions in the Docs finding the rest out on our own. Maybe there's some kind of Darwinistic thought process involved -- let only those aspiring developers succeed who are the fittest in learning by trial and error... Life is (rather: for me has become) too short for dealing with lacking documentation.
thank you! Now it works, it's so hard to follow this tutorial with the newer version...
That helped me so much!
Keep on making Godot Tutorials.
I would like to see them all!
After striking more complex game dreams off my list for the time being and settling for something I might actually be smart enough to complete, I managed to get a breakout game running by myself. The only thing I wasn't fond of was the way the player didn't have control over the ball's movement after hitting it.
Your idea with that Position2d node sounds good and your results prove that it's a good way. When I have changed that in my code, I will make duplicates of my brick scene next and invent some new brick types that need to be hit more than once and earn the player more points. Considering what went on in classics like Arkanoid or Traz back in the good old days of C64 gaming, there's quite a lot to do yet... ;)
Thanks for sharing this with us!
already knowing about the vector math gave me a huge confidence boost because I was in precalculus and we leaned all about vector math.
Thanks for the new video Ben. Keep up the great tutorials.
I couldn't get the magnitude using "get_linear_velocity().lenght()" but I solved it using Pythagoras theorem.
So I did "sqrt((get_linear_velocity().x * get_linear_velocity().x) + (get_linear_velocity().y * get_linear_velocity().y))".
9 months later, but you spelled "length" wrong
@@wesleynewcomb 9 months after your comment, but that deserves a like

Excellent job Ben, as always.
Such a great tutorial. Perfectly paced and really easy to understand.
Thank you very much! I've just started doing videos on Godot 3.0. Hopefully I can do a good job with them as well :)
You explain everything so well. Just got yourself a new subscriber!
Getting "Invalid get index 'type' on base: 'InputEventMouseMotion')." error?

Thanks for putting this together. I made one of these games using UE4. This engine was so much easier for this type of game.
Looking forward to more on Godot if you get the time. :) :)
Yea, but using UE4 to make Breakout is like using rocket fuel to power your car.
1) Before i forget, in later versions get_pos is replaced by get_position() among others. please refer to the featured comment in th-cam.com/video/GncaMNv7Fso/w-d-xo.html
2) the movie thing can be accessed by rightclicking the ball and clicking "save branch as scene"
Great video as usual
Thanks a lot for this, very easy to follow!
Thank you so much for this tutorial. With the preload and instance part, I get in love of this game engine. Because, with Unity I did'nt get this. Godot Rules.
you can also use export var instead of the constants, let the level designer edit those values without changing the code :p
Godot Engine book by B. Anderson coming soon
+Ruslan Sleptsov (indieGEAR) Lol no. Hahaha. I'm working on updating my GameMaker book right now. Writing a book is a pain.
+HeartBeast i was kidding...
good luck with your book!
+HeartBeast That is great news!
I'd constantly question my motives and have trouble finding the motivation to write a book knowing that with the next version of Godot, a good deal of my explanations, code examples and screenshots were already invalid.
I didn't multiply by delta because that seemed to me as changing the dimensions of velocity. It worked fine. I set SPEEDUP = 40, and MAXSPEED = 3000.
this has been a great tutorial. i have had ZERO game dev or code writing experience and this was a great way to start.
i wondering thought if there is anywhere i can find other files that i can find that are already pre-made so i can work on practicing writing the script for it?
Thanks so much for the tutorial, I love the way you explain stuff.
I'm using Godot 3.2 and it had some problem with this part of the Paddle script:
func _input(event):
if event.type == InputEvent.MOUSE_BUTTON && event.is_pressed():
var ball = ball_scene.instance()
ball.set_position(get_position()-Vector2(0, 16))
get_tree().get_root().add_child(ball)
So I did some searching on the Godot docs page and managed to get the function working like this:
func _process(delta):
if Input.is_action_pressed("MOUSE_BUTTON"):
var ball = ball_scene.instance()
ball.set_position(get_position()-Vector2(0, 16))
get_tree().get_root().add_child(ball)
But I had to setup MOUSE_BUTTON as a name for the mouse button input under Project > Project Settings > Input Map for this to work.
thanks, also just learning godot and using 3.2
when i click the left mouse button tho, it spawns in 4 balls. idk how to set that to 1 ball only.
This one works for me but the problem is there's so many balls being made in 1 click. Does anyone know how to fix that?
@@juaquimcalamiong8957 I had to make a global variable i.e. ("ball_alive") and reference that in the if statement. If left click and ball_alive == 0 then run that code and at the bottom of that code make ball_alive = 1
if Input.is_action_pressed("restart_ball") && GameManager.ball_alive == 0:
ball = ball_scene.instance()
ball.set_position(get_position()-Vector2(0, 16))
get_tree().get_root().add_child(ball)
GameManager.ball_alive = 1
@@trevorleesmith14 Thanks! So it releases a ball at 0 then immediately turns it to 1 so no additional balls would release upon holding the left mouse button right? Damn it’s been 6 months since I did this. I’m prioritizing my other hobby now so I haven’t really coded in a long time.
@@juaquimcalamiong8957 That is correct!
I have tried coding many times myself, but always get sidetracked. Hopefully I can stick with it this time.
Do you could make some videos on the coding aspect of game development?
Perhaps a video on how to learn GML or the process you go through to make a script.
when next episode od godot, and what are you wanna do in this ep? I think you should do label which show us score and live, when live = 0 then show level hame over your score is
If you can't find the movie button at 16:35 you find it by *right clicking object* then click *Save Branch As Scene.*
The reason you had such slow speed was because of min(speed * delta, max_speed * delta). Essentially, you mulitplied max_speed(300) by 1/fps. So if physics fps is default 60, it would be velocity = min(direction*speed*delta, 5) and 5 is much lower than original velocity.
That's a good method with the 2D point
I can't seem to get past the point after adding this line "if event.type == InputEvent.MOUSE_BUTTON && event.is_pressed():" I get a "Invalid get index 'type' (on base: 'InputEventMouseMotion')." error! Did something change in Godot? I'm on v3.0
Ok it seems to work by changing it to: "if event is InputEventMouseButton && event.is_pressed():"
No worries, I always try to pass the solution on if I end up working it out myself :) After a while of search the docs you can eventually figure out most of the changes. I got stuck many times haha.
if(event is InputEventMouseButton && event.is_pressed()): works
so 1 == 1 and 1 is int, '==' compares btw. values but 'is' gives if 1 is an integer
if anyone is struggling with how to create a scene from a node in the latest godot version just right click on the node and click on the "save branch as scene" option.
how to display "game over " ?
For any Unity users out there, would making a scene of the ball be the equivalent of making a prefab in Unity? Thanks!
Nobody is born cool... expect of course....
The people who comment about how to do this in the newest version
Don't know if you saw something when you hit you left attack key there was a black ball came out!
Is there anyway to program in lua? It looks like it would work, but I dont want to have to learn a whole new programming language.
Hello, Ben. How are you today?
I have one question (or maybe two) regarding the logic behind the ball control. Here we go:
1. Getting the paddle's position instead of creating a Position2D node to get its position would not have the same effect?
2. Why not apply an impulse instead of multiplying the delta?
I am quite busy, so I did not have the chance to test it myself. Hope you can answer me.
Cya, and I am a big fan of your work.
Did you have time to test it 3 years later?
The paddle's position would result in the paddle's origin coordinates every time, making the ball bounce up with the same direction vector. With Ben's method, different points on the paddle's surface are taken into account and, combined with the Position2d node, result in different direction vectors, making the ball bounce of the paddle depending on where the ball hit the paddle. At least, that's how I understood it.
@@ChrischoBoardgaming this is 4 years old..
@@naeemchowdhury6280 Does that fact make understanding the problem/solution obsolete? I learned stuff from a video that's four years old. I sometimes even learn stuff from books that are hundreds of years old.
Idk wtf happened but I deleted the ball scene to create a new ball scene and rename it to xml but now I open the project and its missing due to dependencies and just crashes so I think I have to start over... is godot really doing this? I cant imagine wtf would happen if I did this by accident on a huge project, jessus.
direction.x is so small when you hit it with the right side of the paddle
is there any chance of a new vide on this project that can help to explain how to add a gameover screen or dialog popup, which might also server as a basis for the next level screen, I have tried several different approaches for popups but can not seem to get a handle on them
You could do the following:
- Create a node (e.g. Control), inside, have whatever needs to be displayed on the GO screen. Position it far down in the scene tree to have it above other game elements.
- make this node invisible in _ready function (yournode.visible = false)
- when, e.g. three balls have been dropped, call your GO function (game_over())
- inside game_over(), you first set yournode.visible = true
- still inside there you probably need to stop/pause any physics process (set_physics_process(false) currently works for me) in order to prevent the game from continuing
- add a button inside and connect its pressed signal with your main code (_on_Button_pressed()) and have the game call up your init function to start again or your enter_name() function for any highscore list stuff ;)
heart beast can youy do a tutorial on a game like flappy bird (launching objects from a controled point with controled speed and direction)
As I guess the linear velocity is the same thing as speed in GM.
So, I have the problem that the ball doesn't appear in the window of the game, it appears out of the windows(the game is still running); I believe that is a problem with de the snap or the grid, because I set te values in the script to (50, 20) and it does appear. I wish that one of you can tell what is wrong (sorry for my bad english)
Pd: here is the code
func _input(event):
if event is InputEventMouseButton and event.is_pressed():
var ball = ball_scene.instance()
print(str(get_position()))
ball.set_position(Vector2(50,20))
get_tree().get_root().add_child(ball)
Have you ever thought about making tutorials for unity2d?
22:30 I managed to load BrickOne.xml but it now like Ball.xml a tab. I could not find a way to load it to part node World.
For those that come after me, I figured this out. You can drag and drop the BrickOne scene from the file explorer onto the Bricks node to instance the scene like in the video.
Hey, these videos are helping so much to understand how to structure Godot projects and especially creating them. I have stumbled upon two problems and I was not able to find my mistake yet.. The first problem is, that when the ball hits the paddle it bounces every time in the exact same direction back, so something with the anchor doesn't work.
My other problem is the instancing of the ball. When I hit the mouse button it creates new balls but they are located under the paddle and shifted to the right (so now when i want to create new balls I have to go as much to the right as possible with the paddle). I don't know what I'm missing here.. Here ist my code, I hope you can help me guys.

yes, there is some godot 3d tutorials that he made.

Hey, im on GODOT 3.0.6 now(12/4/2018) and after the "body.queue_free()" line, inputting the script after that, the game doesn't run. Did I miss something?
probably, but in some other place
Hi Ben, I've been working on this project for about 2 days and once i finished scripting everything up to 28:50 and when i ran the script and clicked on my mouse i couldn't shoot the ball. if you have time please respond.
Thank you
P.S you're an awesome youtuber
sorry, never mind I just went over my code and spotted the error.
thank you
Okay, so creating "Scene" of an object is the same as creating a Class? That doesn't seem too hard to understand. It sucks that I'm using a newer version of Godot, since a few key buttons seem to be in different places than they are in this tutorial. It took me awhile to find out how to create an object Scene, not to mention trying to group objects together all at once doesn't seem to work, I have to do it individually. That's also quite different than adding objects to an array or something, but I guess this is for those people who prefer to build their levels by drag and drop.
Godot's language is a bit too foreign to me, so I'm not sure about this one..
Do mini scenes seem like a prefab in unity?
it is
Sometimes the ball will hit a brick and bounce off but the brick does not disappear. Does anyone else have this issue or know what I could be doing wrong?
same here.... been baffled for a couple days. None of my bricks disappear. Do ANY disappear for you?
It seems that the bricks must be hit in order - can't understand why
@@Jeff2207xx Checkout the part of the tutorial where has this code.
#########
# ball.gd #
#########
func _physics_process(delta):
var bodies = get_colliding_bodies()
for body in bodies:
if body.is_in_group("bricks"):
body.queue_free()
Now rememnber for these to work Benjamin mention that on the nodes, you need to setup several things, first you need to group all of the bricks nodes, into a group (in godot 3.0, next to inspector tab, you have the node tab, you can add a group name to each node, needs to be repeated to every brick node).
Additionally, there was the 2 settings to in the ball node (rigidbody2d) set contact_monitoring to on and set the contact_reported to 1.
I think logically it means that if detects a collision, then the code on the paddle.gd the "body.queue_free()" will work to remove each brick collided.
Don't know if this helped.
Godot 3.2.3
How to prevent ball from rotating?
I'm already made:
RigidBody2D/Phisics Material/Friction = 0
It dosn't help. "Ball" still start to rotate after hitting an edge of Paddle
Found the answer, set
RigidBody2D/Mode = Character
It helped. If somebody have a beter answer, it is wellcomed.
Seems like creating scene from node functionality has been removed from godot 2.1 :(
Yeah, I cant find it either
Yeah this was tricky for me to figure out. Right-click on the node and select "Save Branch as Scene." This should provide the same functionality as the button in the video.
Patrick Cole yeah, I figured it ou eventually. It`s really anoying the newer version is so much different.
It's their trust me
what language does godot use?
Godot uses its own. It's a Python-derivative, so if you know the basics of Python they can apply here.
if _event is InputEventMouseButton && event.is_presget_relative_transform_to_parent():
can somebody tell me why doesn't this code work, and tell me please with what to replace it with
please i can't run the game
use this instead:
func _input(event):
if event is InputEventMouseButton:
var ball = ball_scene.instance()
ball.set_position(get_position()-Vector2(0, 16))
get_tree().get_root().add_child(ball)
@@foolishflamez thanks 🙏
Np :) i got stuck on this for abit too lol
Can I script in c++?
yes
Please complete the rpg tutorial
patience is a virtue man. he will finish it.
you spelled anchor wrong
19:02 saving myself a timestamp, dont mind me
hey, this tutorial was going great until this moment, probably one of the best I've followed to be honest, i'm sure i'm being stupid but I cant get passed the 27 minute mark, i've taken the advice of other commentators on the changes to godot 3 onwards, this is my code. I'm getting a "nonexistent function 'instance' in base GDScript" for the var ball line when i click and can't guess my way out of it this time. please tell me how i'm being stupid, thanks
extends KinematicBody2D
const ball_scene = preload("res://Scenes/Ball.gd")
func _ready():
set_physics_process(true)
set_process_input(true)
func _physics_process(_delta):
var y = get_position().y
var mouse_x = get_viewport().get_mouse_position().x
set_position(Vector2(mouse_x,y))
func _input(event):
if (event is InputEventMouseButton && event.is_pressed()):
var ball = ball_scene.instance() #ERROR HERE
ball.set_position(get_position()-Vector2(0,16))
wow, staring at this for an hour. really do not know what i'm doing wrong, i;'m an idiot. send help
@@supercoolemile6129 Hey! No worries! I'll do my best to help. so it seems you are loading Ball.gd instead of the Ball scene. Are you using .tscn for your scenes? I don't remember which file extension I used. You just want to make sure to load the scene instead of the script file in your preload. The error messages is saying that a gdscript doesn't have the instance function and that is because instance is only a function for scenes. Does that make sense?
@@uheartbeast Hey, thanks for the reply, I'm really enjoying your tutorials, this is the furthest i have ever gone making a game to date. Your advice worked perfect, i was going mad trying to find what was wrong, i didn't notice i was loading the wrong thing, its going to teach me to organise things better in the future and i definitely learnt something unforgettable about Instancing. Thanks again
@@supercoolemile6129 Glad I could help! It is always frustrating to get stuck. I've been there before. A lot of times haha.
FAKE!!!! there is a floating mic in the bottom right corner. 0:00 through 43:59:20
+Game Jam! SHHHHHHHH!
Here another maths
if body.get_name() == "Paddle":
var texture = body.get_node("Sprite").get_texture()
var paddleWidth = texture.get_width()
var paddleX = body.get_pos().x
var d = (get_pos().x - paddleX)
# 0.6 es el % del angulo para que no sea totalmente 0º
var vxFactor = (d / (paddleWidth * 0.5)) * (0.6)
var angle = (PI/2.0) * (1 - vxFactor)
var vx = cos(angle) * MAX_SPEED
var vy = sin(angle) * -MAX_SPEED
set_linear_velocity(Vector2(vx, vy))
Hey please do rpg maker series btw thx for that series
+Brad Hrad You're welcome :) More GM RPG videos are on the way.
+HeartBeast you are a great at explaining stuff and I didn't mean game maker I meant a cool engine simple called rpg maker it is awesome but if no thanks for reading and replaying
+Brad Hrad hell its not awesome really dont use it to make games please or ill kill myself
ok ok jesus calm down ok he will not
god some people man (jk)
hypotenuse would be the least complicated thing said here. lol
nice floating mic! can i get one!
(lol)
it's called Godot bro.
its called godot, but pronounced good-doe
like robot, ask the godot authors
guys sorry but after long time search i found how i do it thnx anyway
in Godot 4.0:
.instance(), is instantiate()
12th!!! YAY.. lol. Saw the tweets. Gotta love the insta dislikes!
+Sayado -MC I think some people were upset when there was a Godot tutorial instead of a GameMaker RPG Basics tutorial posted. I do not agree with that, but that is why I think there are some instant dislikes.
+Michael Capone, yea lol. He tweeted about it to rm2kdev and Shaun Spalding. Funniest. Thing. Ever
This episode frustrated me a little as you kept derailing and postponing, took me a while to get everything working this time.
please for the love of sanity, put spaces around your operators
Haha you are very passionate about that it seems.
Benjamin is not a bad lookin fella
God, it's not "Ancor", it's "Anchor". Literally unwatchable :P
Nice tutorial BTW, even though I don't really like this Godot thing.
+Arkadiusz Jagiełło LOL! Learning Portuguese has destroyed my English XD Oh well.
Como vai o seu português? Fiquei curioso 😉
I just assumed that was how Americans spelled it :P
