Sphere Colliders not to overlay. Pls help.

Hello guys,

I created two sprites that are circles basically and I added on them Rigidbody(NOT 2d) + Sphere Collider (not 2d). So when I add this little code on the prefab when the objects touch they kill eachother so I know the collider works

Code (CSharp):

1. void OnTriggerEnter(Collider other)
2.     {
3.         if(other.gameObject.name == target.gameObject.name)
4.         {
5.                        
6.             Destroy(GameObject);
7.         }
8.  

Now the issue is that I want to delete the Destroy function and make the objects not to overlay so they will get close to eachother until they touch but not go through eachother like cells.
I am not sure how to do that.

 

Try adding Rigidbody (not 2D) components to both of them. Their motion will then be supervised by the physics engine, which means they won't go through each other. It also means they will fall down (toward -y) due to gravity, so turn off gravity if you don't want that to happen, either in the Rigidbody components (Rigidbody.useGravity) or by using Physics.gravity.

 

Yeah both objects have a rigidbody and a sphere collider on them and they are moving randomly in space (movement made with script) So then I click a location in space these particles get the target destination and they go to that point but I don't want them to collide, I want them to go to that point in space and not go one on top of the other.

 

If you're using 3d versions of everything, then you probably need to prevent the objects from moving into the z direction. I think you can do this from the inspector on the rigidbody constraints: http://docs.unity3d.com/ScriptReference/Rigidbody-constraints.html

 

Right now it looks like this (they get one on top of the other):


I want to be like this:

You see, they move as close as possible to eachother but never overlay...

Once again, the circles are 2d objects (sprites) and I attached to them 3d collider (sphere collider) + 3d Rigidbody (Rigidbody).
Also I disabled the gravity in Unity settings.
So now when I tell the circles to go to the corner of the screen for example they just go there and overlay so in the end there is just one circle with all the rest under it (or on top) , what I want is them to go to that place but just group around.
