Linecast between character and camera doesn't ignoring Characters collider.

Question

I want to make camera get position from collision WITH WALL (in order to see character when he stand back to a wall). In order of this I: 1) create a layer and give this layer to my character (and all its children object) 2) casts a line (Physics.Linecast) between camera and character with invert mask with this layer, which I make invert.

But instead of IGNORE the players collider (via layerMask), Linecast somehow MAKE A COLLISION WITH CHARACTER'S own collider give this position to the camera, disregarding an exception of its layer. I try the whole week but I don't know what to do =( Please somebody help me fix this problem via Linecast (or Raycast).

 RaycastHit hit = new RaycastHit ();
 int layerMask = 1 << 8;
 layerMask = ~layerMask; //invert a bitmask - we want to collide against everything except layer 8
 
 if (Physics.Linecast(lookAt.position, camTransform.position, out hit, layerMask))
 {
     Debug.Log (hit.point);
     camTransform.position = hit.point;
 }

Is your player assigned to layer 8? Have you tried projecting from a point just in front of your player instead? There is an example here - https://docs.unity3d.com/ScriptReference/Physics.Raycast.html

It also seems to suggest using Raycast will ignore colliders attached to the origin.

Yes, my player attached to 8 layer, I tired via Raycast but all the same( alt text

Are you certain it is hitting part of your character? As a test, ins$$anonymous$$d of having layer$$anonymous$$ask as a local variable change it to a public member, like so

public layer$$anonymous$$ask : Layer$$anonymous$$ask;

Then in your code don't invert it, just pass it to Physics.RayCast - In the editor you can tick all the layers you want to detect. Play with those and see what happens.

Try Changing your layer mask to

Int whateveryourlayerpropertyis = LayerMask.GetMask("Name Of Your Layer");

then invert that and put it in.

whateveryourlayerpropertyis = -whateveryourlayerpropertyis;

i think this should work. i always use Get Mask for layers. It will always work.
