ignoring enemy collision with eachother

Unity Engine
1

ok, I have a room full of zombies but they cant get out of the door because they collide with eachother and jam the door. does anybody know how I can get around this?

@Feyhu
I had a similar problem with a previous project. What I did was I put the enemies on a layer and had the enemies ignore the layer.

Hope that helps,

Or you could use Pysics.IgnoreCollision an simply ignore collisions between all enemys!

I cant figure out how to get it working for multiple zombies from the same prefab.

I keep getting:
Assets/Scripts/EnemyCollision.cs(13,17): error CS0117: UnityEngine.Physics' does not contain a definition for IgnoreLayerCollision’

Urgent bump!

Can you post the script that’s generating the error, and also indicate which line generates the error?

7 
using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {

	// Use this for initialization
	void Start () {
	
	}
	
	// Update is called once per frame
	void Update () {
	Physics.IgnoreLayerCollision(Enemy.collider, Enemy.collider);
	}
}

bump… again, need it done by midnight, please help

I had the same issue and put all of the enemies and their bullets on layers that are ignoring each other under Edit->Project Settings->Physics.

I also had an issue where I needed to dynamically have the player ignore an entire set of collisions, then an entirely different set of collisions. Doing this for each object would suck, so I set up layers that get toggled.

the code snippet goes like this:

if(redEmp) {
			Physics.IgnoreLayerCollision(10,11,true);
			Physics.IgnoreLayerCollision(10,12,false);
			Physics.IgnoreLayerCollision(10,13,false);
			Physics.IgnoreLayerCollision(10,14,false);
		}

It’s very brute force, but works. Note IgnoreLayerCollsion only seems to work with numbers.

Hope that helps.

same problem, doesnt have a definition for IgnoreLayerCollision

Upgrade to Unity 3.

but but but… will it require changing any of my scripts?

13

Maybe, it depends on what you’ve used.

Insert a random variable named More_Than_A_Feeling, the powers of Boston work in mysterious ways

quit spamming josh

16

Sorry man, I had to, but did you even try it? You never know

17

wow, a soon a i saw “more than” I knew you were referring to boston

If you’re not using Unity 3 and if upgrading will make it difficult to finish your project on time, take a look at Physics.IgnoreCollision(). You’ll have to specify each pair of objects for which you want collisions to be ignored, but if you have a fixed set of objects that you don’t want to interact with each other, this can be done with a simple nested loop.

I will use unity 3…
