3D non Rigidbody/Static (IsTrigger) collision

Unity Engine
1

Hello community,

I hope you can give an hint for my problem. I try to detect an collision between two objects and undo the last movement when touched.

  • One object is (half) static (only instant teleports every 5 Minutes), attached:

  • Sphere Collider

  • the other object is my Main Camera, attached:

  • Sphere Collider (Is Trigger = true)

  • Rigidbody (Is Kinematic = true)

  • Script (GetKeyState for movement & OnTriggerEnter) [Code below]

It “works” but the movement is very twitching, because it goes into the collider and back outside until the user notice it, and stop pressing the key :frowning:

Is there a smooth way how to do that in unity?
Thanks in advance, I’m going crazy.

private bool colliderEntered = false;

// Check collision
    void OnTriggerEnter(Collider other)
    {
        colliderEntered = true;
    }
    void OnTriggerExit(Collider other)
    {
        colliderEntered = false;
    }

//-----------------------------------------------------------

void Update()
    {
   if(Input.GetKey(KeyCode.UpArrow) || Input.GetKey(KeyCode.W))
           {
               if (!colliderEntered) // no collision move forward & maybe into the collider!
               {
                   transform.position += transform.forward * speed * Time.deltaTime;
               }
               else // you stuck in the collider move out
               {
                   transform.position -= transform.forward * speed * Time.deltaTime;
               }
               lastMove = LastMove.foreward;
           }
        }
// also left, right, backwards, up and down
   }

I’m only new to c# but would a smoothing loop do the job?

Sorry, but I have no idea how a (smooth) loop can help here.
