Is there any way to get solids to not collide against each other? #695

I want to get the enemies spawning and moving toward the player with the solid comp but when the enemies collide they get stuck to each other and can't move. So I want the enemies to not collide with each other. Can you please show me how I do that. Thank you.

My source is here https://github.com/Kentyahoo/MonsterAvenge/blob/main/code/main.js

But here is the logic code:

const fireblob_speed = 100

const fireblobSpec = (x, y) => [
  sprite("fireblob"),
  pos(x, y),
  scale(1.4),
  state("move", ["move"]),
  area(),
  layer("ui"),
  solid(90),
]

onCollide("fireblobs", "fire blobs", () =>{
  pushOutAll()
})

const coords = Array.from({ length: 10 }).map((_, i) => {
  return { x: i*100, y: i + 100}
})
const fireblobs = coords.map(c => {
  const fireblob = add(fireblobSpec(c.x, c.y))
  
  fireblob.onStateUpdate("move", () => {
  	if (!player.exists()) return
  	const dir = player.pos.sub(fireblob.pos).unit()
  	fireblob.move(dir.scale(fireblob_speed))
  })
  return fireblob
})

I see you using 2000.2.9 in your repo, I recommend you update to latest beta 3000.0.0-beta.3, cause there is an option in area({ collisionIgnore: ["tag1", "tag2"] }), there is some other breaking changes in v3000, should read this blog. Notice there's an important bug with stretch and letterbox screen resize.

Beyond that, there is no way to ignore collisions according to a tags in version 2000, there's the layers() system where every layer() ignore collisions with other layers, maybe that can help you.

I cannot find the place where you can update to the kaboom.js version 3000 beta

We're releasing Kaboom v3000 beta! This major version update includes a lot of new features and improvements, and also breaking changes (see migration guide below).

To try the beta version, install kaboom@next

$ npm install kaboom@next
<script src="https://unpkg.com/kaboom@next/dist/kaboom.js"></script>
or use this Replit template

In the blog previously linked.

I am having trouble getting it to work.

I installed npm and did npm install kaboom@next

I created a HTML file with the following:

<html>
<script src="https://unpkg.com/kaboom@next/dist/kaboom.js"></script>
<script>console.log('hi')</script>    
</html>

I see "hi" in console, but the page is blank.

I don't understand how to "use the Replit template".

Please advise.

thank you.

I think it depends on the setup of your dev environment. I see in your repo you are using NPM, only run inside your project folder npm i kaboom@next and you should be ready.
