3D non Rigidbody/Static (IsTrigger) collision

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:

1. Sphere Collider

- the other object is my Main Camera, attached:

1. Sphere Collider (Is Trigger = true)
2. Rigidbody (Is Kinematic = true)
3. 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

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

Code (CSharp):

1. private bool colliderEntered = false;
2.  
3. // Check collision
4.     void OnTriggerEnter(Collider other)
5.     {
6.         colliderEntered = true;
7.     }
8.     void OnTriggerExit(Collider other)
9.     {
10.         colliderEntered = false;
11.     }
12.  
13. //-----------------------------------------------------------
14.  
15. void Update()
16.     {
17.    if(Input.GetKey(KeyCode.UpArrow) || Input.GetKey(KeyCode.W))
18.            {
19.                if (!colliderEntered) // no collision move forward & maybe into the collider!
20.                {
21.                    transform.position += transform.forward * speed * Time.deltaTime;
22.                }
23.                else // you stuck in the collider move out
24.                {
25.                    transform.position -= transform.forward * speed * Time.deltaTime;
26.                }
27.                lastMove = LastMove.foreward;
28.            }
29.         }
30. // also left, right, backwards, up and down
31.    }

 

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.
