can you make tutorial that you can read for the beginners and advanced
do you know how to use the same variables in different scripts
I have a question, how does printing affect the game? I'm a real noob I'm sry
@@saltedcaramel536people just use it to debug their games, like if something isn't working then it won't print what should be printing. Hopefully I explained it well enough cause I'm kind of a beginner as well
@@openingchain328 ohhhhh
Tysmmm
I love how these videos are short but understandable. Other people I looked at had an hour video on this.
Only one hour you need at least 20 hours practising reading to learn your scripting small games
@@nikos4677 Don't you mean my BIG GAMES man? I do.
@@nikos4677 you dont need an hour long vid for variables is what he meant
same
@EpicGreenYoda If you know qny other language you can learn lua in 20 to be able to make roblox games and if you dont know something, you just look at the dev forum
i like the fact that dev king laughs when doing small stuff like this, really shows he's very passionate of scripting. subscribed
Exactly all the others are like robots
@@Willrb833 ikr
@Darts Unlimited yeah I am subbed
if u wanna read a small little thing about variables here u go
variables always start with local, then u wanna insert the name of ur part here, then space equals = game.Workspace.Part
for example
local mypart = game.Workspace.Part
mypart.Transparency = .5
mypart.Reflectance = .4
etc
if this was helpful let me know by replying or liking this comment (dont have to)
F0RW1RD bruh variables doesn’t always start with local. Do you know what a global variable is?
DONT ALWAYS
@@masterlegend2944 no
this is literally a starters video as well
so it doesnt matter
These videos are the perfect length great job honestly. I lose focus when videos are long and dragged out, these are bitesize and I can understand perfectly
My mom thought i was watching a math video
XDDDD
Crazy
😭
Lol
More like some food video eating hotdogs and hamburgers lol
The good thing about watching beginners tutorials even though I am an experienced scripter is that you learn small things that you didn’t know about
Master Legend father, parameters still confuse me XD but this code I understand
game.Part.Touched:Connect(function(hit) if game.Players:GetPlayerFromCharacter(hit.Parent) then hit.Parent.Humanoid.Health = 0 I can only do a kill brick
Lime Blox yeah cuz this events and functions have their own parameters
@@simimadlani Never have a 0% day. Always work on scripting even if its just for 10 minutes.
sup tap idk if u remember but i cant wait to watch this series and get better at scripting so keep the videos coming plz
I'm glad and yes I remember you. You donated me like $5 bucks :)
Wow
@@TheDevKing Can you still Remember him?
@@TheDevKingwhat about now
ofc
@@DhruvPatel-c6g
4 years ago, i was learning scripting from you but then 1 year later i quit in order to focus on irl stuff. Now since everything is in check and good.. i started again learning and first thing came to my mind is that i should go back to thedevking videos. These videos are so short, simple, yet so valuable unlike others who yap to get more revenue from TH-cam monetization. Thank you devking, your a truly king among the roblox scripters.
Your tutorials are awesome, finally something i can understand as the other ones are very confusing
This guy is god- Any other vedio takes Hours but doesnt teach you anything! How is it possible that this is GOOD
I just learned p5js, and these tutorials are really helping me switch over. Thanks so much dude!
When they say I cant use google for math homework so I use roblox studio :)
Big bran
YOU GOT ME
big script + brain
@@abdulmoiztayyab you big brain
big brain
Today morning i had no idee how to code in roblox studio and everything seemed so confusing but just by watching only your first 2 code tutorials everything seems a bit clearer now. Ill continue watching bc i wanna learn everything about it
How's learning going? Did you stick to it?
@@Pinepineisfine wow, cant believe its been almost 1 year, i havent touched the roblox studio in a while but i would love making games again
The problem is that its not that fun doing it by yourself...
I just wanna add if you want to add a variable to a string just separate them with commas
Example:
local sandwiches = 10
print("I have",sandwiches,"sandwiches")
or do: print("I have"..sandwiches.."sandwiches")
Thanks
As a C developer this pains me in the inside
Why@@Aaznos
Should be printf("String 1" + "String 2"); not those .. things
this journey looks promising, cant wait to compare myself now to the future me when i learn scripting :D
There are a lot of youtubers which show you how to script but they all are very confusing. Thank you for making scripting easy to understand.
you right alvin blox is like djdfvnfdildsvlkvnvknvslvxnvfljvndfnflnx;vjxffljlkb
Lol
literally tysm i COULD NOT figure out what i needed to make my script work until i watched this video and remembered that variables existed
variables are literally the basis of any program. How can you forget about variables?
You actually made my day so much. i began with scratch but wanted to learn more. and bc of these videos you made me so happy!
this is honestly a great series, not only are you helping people learn but you also seem to have fun doing it, thank you very much
I find these kind of vids so useful because I am a beginner coder and never new how it worked😂
what i learnt from AlvinBlox = local ("If Parent hit Children-Children will die")
what i learnt from TheDevKing = local TheDevKing = "Awesome"
XD
This comment was a year ago, and I am not hating on alvinblox ^v^
ngl true
AlvinBlox’s vids are long boring and hard to understand TheDevKings vids are short and easy to understand
@@CookieMasterRBLX personally I think they both do amazing jobs explaining, but DevKings videos are short and sweet that I'd why they are preffered.
Is*
@@alphie6298 plus thedevking has advanced scripting tutorial
These tutorials are amazing, short, and just so easy to understand
Thanks bro this really helps! i love that your vids are short but do a great job at teaching the scripting! Subbed for sure!
Here are important things you need to know while defining an identifier ( Variable ) in your script
1) Should not start with any special characters such as / , + , - , % , @
2) It cannot contain any special characters as mentioned above EXCEPT FROM the underscore i.e " _ "
3) You cannot start the identifier with a number
4) Identifiers are case-sensitive when it comes to programming languages... So be careful while calling the identifier in the print statement
For those who didn't understand the 4th point,
I'll write an example:
Code:
local My_Name = 3
print(my_Name)
--This will show an error as " my_Name " hasn't been declared but " My_Name " is.
Here's how you can add two variables containing numbers as well as an identifier( Variable ) assigned to a text:
Code:
local My_Name = 4
local Favorite_DecimalPoint = 4.5
local Text = "Hiiiii"
print(My_Name+Favorite_DecimalPoint..Text)
--As you can see, I've added " .. " after the identifier, Favorite_DecimalPoint. This tells the interpreter to not execute Text ---identifier in the arithmetic operator, " + " .
Unless you still understand the above code, here's the output of it:
" 17:44:02.262 8.5Hiiiii - Server - Script:4 "
8,5Hiiiii is computed in the print statement
Leave a like if you understood :)
does "," work instead of ".."
@@rishondsouza2312 No
Idk what .. Does or means
what@@Electrine18
@@Electrine18 It tells the program to not include the string in the equation, but put it at the end of the answer of the 2 variables. (Idk if I explained that well)
Thankyou DevKing, I have been stuck on variables for a while and this vidio helped me a lot!, you explain everything so well, thank you!!
These videos are amazing I was starting to learn Roblox scripting and I wanted to learn variables and I watched ur vid and this is the only I understood lmao
U are the real developer goatt
Im glad these are in bite sized videos and not an intimidating multi hour video like some people do.
Alvin Blox and all the others are soo complicated you have a little kid that understands. Keep up the good work!
For the future there are two types of variables. local and global! these will be used for scope and returning on part 6
Whats local mean
@@progamerjakestudios8553 local is is like the player Example: LocalPlayer.Humanoid and then it goes on
@@VortexVR2010 kk
This dude fell down from heaven and answered all our prayers.
Litteraly the best TH-camr for learning scripting
A variable inside a Table can contain different fields of data, and you use [ # ] to select a section.
The fact that you dont just show the commands in the script you also teach them. I start coding in C++ last year in school and for now I see the same things with diffrent names. ( I forgot almost all of what I have learned and it is refreshing)
First I didn’t believe you. Now I’m actually learning!
if yall are confused think of it like shortcuts for example HELLO is a shortcut for 6 so when you say local HELLO = 6 when you say hello the game will look at it as 6 instead of hello
Local TheBestScripter = "tapwater"
Wait(1)
Print(TheBestScripter)
--thanks bro
this youtuber rocks its so easy to learn coding this way
I learned variables on my own but this made me understand it better!
This is what I fucking need a youtuber like you that don't waste 10 seconds intro, 20 to 30 minutes video and talking too much but this... Yes this is what I need a very good teacher 👏👏👏
Man U make Children’s understand.Appreciate it!
This guy really loves his hotdogs!
If i continue watching this i will be pro at scripting lol
Exactly! :)
@@TheDevKing XD
you are getting there
Keep going bro.
bro when were done with this series I'm gonna put all it together and make a game
Me and my friend just got a game idea and this helps a lot thanks😊
I love how these videos contain a lot in a shortage.
kinda easy to understand
short
useful
no super duper long intro
its perfect
short but effective vid Good Job! u gained new susriber
Your channel is perfect to learn stuff
Other channels explain it complicated
WOW!YOUR TUTOURIALS ARE SO EASY TO UNDERSTAND.You deserve a sub from all my accounts
Youre the bestt I watched your other videos too theyre very good new sub
Video Summary/Notes:
Variables
Variables contain a value (string, integer, etc)
To define a variable: local insertvariablename = 4
Once defined, the variable can be printed or added to other stuff
A variables name cannot contain a space or start with a number
To print : print(insertvariablename)
Variables can also contain strings: local insertvariablename = “TheDevKing”
Variables can also contain decimal integers: local insertvariablename = 5.5
To add variables together: print(variablename1 + variablename2)
I don't know if this was intentional or not but "local" is not used because it's good practice but has to do with the scope of the variable you're creating and it depends on where you want that variable to be accessible exactly. You can either have a local variable or a global variable.
A global variable is a variable that can be used from basically anywhere in your code. Whereas local variables are restricted to the block or scope they have been created in.
thanks i was genuinely trying to figure out what would happen if i didn't use local
One day ill be the best developer!
Pls remember m
@@blue-gloves-and-red-backround i will i swear by it!
yes just believe in your dream and dont give up (btw you remind me of shaneplay video) am trying to learn scripting
@@Fiat_Frenzy TYSM!
thedevking i think your videos are great and are really helpful!
Even in 2024 I Watch this video and understand sooooo well what you teaching thx
Thanks for the tutorial! Had to watch the video to get the concept a bit
thank you! this is very easy to understand and it works
Man Teaches me more about varibles than my teacher does🤣🤣
trueee
a way to learn how to script is to make different word docs for each part of scripting like one for printing and variables and add to them what you learn and keep on adding from different youtubers till you have all the information you need to become a pro scripter.
hope this helps:)
Bro I now use that for when I am learning anything, it's called "taking notes". I also like making examples for it. Really helpful.
Dev King must be hungry
Lol
the year is 2024 and your videos is still enjoyable and easy to understand. 🗿🗿
love these vids!
Great video, This is really well explained in a easy and short video!
yea i watched alvinbloxs 20mins+ vid still didint understand a thing bout variables!
Your helping a lot now I know variables thx:)
I never know how to do math and i dont have a caculator, so im just gonna open my roblox studio and use it as a caculator
Hey not to be rude but I can’t find the output bar, it’s just not there (I probably accidentally removed it years ago.) but is there any way to get it to show, it seems important
idk if you still need help but on roblox studio go to the top bar click view and then find click output
@@TohtoriGerhard Thank you so much!! Now I can see if my scripting is right, I don't think it's possible to show HOW MUCH I WANT TO THANK YOU!!!
Subtitles: Hello guys, its the deaf king
Why do we put *local* in-front of a variable? I didn’t watch the whole video but because it was about variable I wanted to ask here because you have a awesome fan base and you seem like a good TH-camr when I scrolled oh what videos you make.
Thanks bro I wanted to make a game sooooo nice that I would beat Brookhaven but idk how, So I started watching ur tutorials it is helping so much thank you so much.
Thank you
Tap water/thedevking
Very amazing tutorial. There are some stuff you probably should of said but throughout the video it was kind of self explanatory. Amazing content. Btw, when typing these variables, can I type spaces inbetween them? like Local Hot Dogs?
no spaces
It's 3 months old but, for anyone else that might see this, there are usually 3 commonly used styles of writting variables along the programming langues, the first one "CamelCase", the second one "Snake_case" and the third one "Kebab-case", all 3 of them will be understood without problems usually by another programmer. Usually kebab and snake are easier to read but Camel its easier to type.
local TheDevKing = "Awesome"
:D
YOUR VIDEOS ARE AWESOME
if you accidently use a cheesy name just make yourself deserve it like this man
I gained 1 brancell frog this, gonna keep watching your videos and awesom
best beginner tutorial out there
example:
box = 5
print(box)
while the variable is only a word and not in the game like game.workspace or serverstorage etc.
you dont need to type print(box.value) to print the variables value but if you do this with a part it gets a little different
example:
part = game.Workspace.Part
part.Transparency = 0.4
print(part.Transparency)
what this will do is it will check the part's transparency value and it will print the transparency value
you can use script.parent too if you inserted the script inside of a part
Variables can also hold Boolean values, no?
I'm making a monster ink building and I have only listened to this 10/10
@TheDveKing Could you do a tutorial on for Exsample if an alarm goes off LockdownDoors all BoolValues would = true or if the sound gets reset therfore the LockdownDoors All BoolValues would = False which would then Raise all lockdowndoors with one Script.
I love how this guy does everything in a 4 min video. When Alvin blocks does it in a 1hr vid!!!
SAME!
Alvin goes in-depth about everything. That is why their longer while tap water/tdk just blatantly does it. Watching them both would help a lot.
these are actually good
Can you make a vid on how to make RC cars drones and turrets
wut
he is better at teaching than my math teacher.
how u have 6 dislikes u should have 0, because ur vids are AWSOME
this is literally excel.
Subtitles say “the deaf king” 😂
aha now im learning how to script Thanks!
If you press f9 and then go to output and then server you can actually perform commands in game (like print something)
if you're an exploiter, it can surprisingly help in learning how to script because some scripts for games require editing and that requires analyzing the script and knowing what's going on
Anyone coming into this should also learn different data types, especially when declaring variables.
Is there such thing as taking to many notes because i have a lot of notes
Mister Holden No there is not, unless your pc runs out of storage to store you game file :p
Nope, it's perfectly fine.
thank you bro nobody told me when i asked what does local mean
2:25 "what can we do with this?"
eat them ofc
also amazing video i learned alot
that background keyboard is asmr for me
can you help me make my own battlegrounds game?
Thedevking i have a question:
What are the uses of the codes,"Local FavoriteName = "TheDevKing" " and, "Local FavoriteDecimalPoint = 6.0 "?
I think it's just a example
lol this feels like a math lesson but it is very helpful
Damn scripting is so easy with this guy
