I see you haven't uploaded in a while. I wanted to let you know that all your videos have been very helpful to me and that I would like to see more content from you, if you can of course. Thanks for your service.
Thanks bud! Don't worry I will be posting videos again soon. I needed to take some time off to build out a website and do some rebranding, and things like that. Hopefully by the end of this month I'll have a consistent posting schedule. Cheers!
Hi, I just found this channel and it's very clear to follow along, but also I've been watching alot of vids these days because of the steep learning curve... It starts to make a little more sence now...
Thornlock thank you for the support. I’ll be taking off the month of December to work on another project but after that I’ll be posting at least once a week.
i'm very new to unity, c#, making games and stuff. i don't have a deep understanding of most of this, but i noticed that the code you used here 4:29 "if(transform.position.x < screenBounds.x)", the < screenBounds.x part only seems to work when the camera projection is set to perspective. i've been using the orthographic camera projection because i was told that it's better for 2d games. if not would you mind explaining the difference? also do you plan on making a tutorial like this for an orthographic camera projection?
The simple answer is perspective camera inverts the screenBounds value. So if you’re dealing with orthographic either multiply it by -1 or flip the if statements. Hope that helps
@@pressstart6864 thanks a lot for the information. i was able to get it to work with orthographic projection when i multiplied it by -1. i wasn't able to figure out how to get it to work by flipping the if statements though.
At 9:01 you said we could use a boolean that changes to true when the game is ready to start. How do I know when the game is ready to start? Because my game has a title and doesn't start right away, so i dont want the enemies to spawn before the game actually begins, but how can I do this?
So I believe as TaniCorn is pointing out, it should be pronounced co-routine, not Quarantine, although that's all been on our mind recently. EDIT Thanks for the great vid!
I followed your tutorial step by step. My script is identical to yours (have checked for 1h). But nothing seems to spawn. If I put an asteroid manually in, it does, what it should. but if I remove it and try using the prefab, it just doesn't spawn anything... pls help! (using the 2019 Version of unity)
When the camera projection is "perspective" the objects despawn normally, but when I set it to "orthographic" the objects spawn faster than they can despawn. Can anyone help, plaease?
hey mate, I'm having issues I've copied and pasted the same code for destroying the asteroids but they are being destroyed at runtime, any suggestions? Please respond me fast, I have an assignment to finish
Hey this is great thanks! my question is I wanted to add a different object to be spawned so I made a new coroutine, but for some reason that one never spawns its object. Is the first coroutine interfering?
i'm getting an error saying object referance is not set tto an instance of an object for this line of the code and its saying it for both scripts screenBounds = Camera.main.ScreenToWorldPoint(new Vector3(Screen.width, Screen.height, Camera.main.transform.position.z)); any one have any suggestions on how to fix this?
I have a small question, I'm shooting bullets, although it seems I'm creating multiple bullet game objects and I only want to fire one of them when the space key is pressed, how do we limit the rate of a prefab?
Hi , I appreciate the video. Just a quick question : so I'm working on a simple 2D side scrolling runner, the idea is to deliver Pizza to randomly generated houses : green red and blue ( to add a bit of challenge ) , will the script you provided in this video work ? I've been trying for so long but I can't make the houses spawn after the player collides with them. Any help would be appreciated. Thanks.
Hey! There is a bug .... My Obstacles dont despawn and are spawning only there where the camera startet but when the camera is in another position the Obstacles are still spawning there where the camera was at the beginning... Can anyone help?
Hey! great tutorial! Is there a way to increase the rate at which the astroids spawn over time? I would like them to spawn more frequently as the game progresses.
i really like your tutorial. But i want to make a game that needs to spawn obstacles from above and when i tried changing the code i couldn't figure out how to make the spawn above (on the x axis) please help me out.
If i were to do this for a top down shooter i should just replace the values with Z instead correct ? im trying to do this for a top down space shooter
Yes just reverse the code to work for the Y axis: a.transform.position = new Vector2(Random.Range(-screenBounds.x, screenBounds.x), screenBounds.y * 2); Then modify the velocity also, or just add gravity.
Hi , I tried it for Y axis, but the "DEPLOYASTEROID.CS" did not work for me. I tried changing the x axis to y axis, but the spawning didn't work. Pls help me. Thank you.
I used a particle effect. For start size choose a value less than 0.1 and then under Renderer > Material choose "Sprites - Default". Then just rotate it 90 degrees.
Did you create a folder in assets called prefabs and added the rock in there? Then assign the rock from the prefab folder to the script that deploys the rocks, located in the main camera.
Maybe you won't answer but I still want to ask. You wrote the respawn time as "WaitForSeconds(RespawnTime), but I want it to create a new object for each disappearing object condition, not time. So the respawn condition is for another object to disappear. How can I do this? Thanks in advance for the information you will provide. I wish you good work.
My object will not delete when off the screen not sure why maybe there is a problem with the camera bounds , any suggestions? (I had to change the code to what you put in the comments, to make my prefab appear on the screen as it wasn't showing with your original code)
Hey, can someone help me with a problem I am running into? So I am trying to make this script but instead of the asteroids going sideways I want them to go down so I did that but now the asteroids are going down on one line. In the "deployAsteroids" script I have tried to change "screenBounds.x * -2" to "screenBounds.y * -2" I have also tried to change the Random.Range screenBounds to x instead of y. Btw I am a beginner coder so I am sorry if it is something obvious.
I’m am working on a project for college and this really helped me out, however I’ve been trying to connect it alongside a network manager and I can’t get the second asteroid script to work like they just don’t spawn in. Any tips?
@@pressstart6864 It appears static, but it turns out it's technically moving? I tried the code you suggested to someone having a similar issue and it resolved my problem :)
How would you try giving the spawning transforms of the 2nd spawning object a bit of a minimum distance from the spawn transforms before? What I mean more precise: I want to spawn several objects in a scene but they won't move nor disappear after they spawned. They should spawn in a pre-set area with a pre-set number of objects that spawn, but they should all have a minimum distance around them, so that the meshes won't overlap. I'm still rather new to coding so I'm not always quite sure what can and can't be done, would appreciate the help ':D
In asteroid.cs, change this line to move from top to bottom: rb.velocity = new Vector2(0, -speed); and in deployasteroid.cs change this line to have it appear above the camera: a.transform.position = new Vector2(Random.Range(-screenBounds.x, screenBounds.x), screenBounds.y * -2);

You need to set your main camera. Basically it's just a tag in the inspector. Set it to main and the code will work

If i were to do this for a top down shooter i should just replace the values with Z instead correct ? im trying to do this for a top down space shooter
It's relative to your camera. You could just rotate your camera or yes change certain values. Not every project is going to be the same.
does somebody knows how to the same thing but the asteriods goes down not sideways
Also is there anyway to code it so instead, it seems like the enemies are 'dropping' from the top of the screen to the bottom?
Yes just reverse the code to work for the Y axis:
a.transform.position = new Vector2(Random.Range(-screenBounds.x, screenBounds.x), screenBounds.y * 2);
Then modify the velocity also, or just add gravity.
