Script is stuck in OnCollisionStay

Questions & Answers
1

I typed up a script (basically copying from here) which uses the OnCollisionStay function. I added some Debug notes so that I could see what state the script is in, whether it is detecting input or sensing collision and things like that. However, whenever OnCollisionStay is triggered, movement controls no longer register, and “Movement input received!” is no longer logged in the console. Is there something I’m doing wrong/not understanding here?

You are setting is grounded to true in your physics.raycast if statement. Move your call to movement to outside the if(!isGrounded) statement. My guess is it is never getting set back to false.

function FixedUpdate () 
{
var capsuleCollider : CapsuleCollider = gameObject.GetComponent(CapsuleCollider);
if (!isGrounded) 
    {
    if(Physics.Raycast(transform.position, -transform.up, capsuleCollider.height/2 + 0.2))
       {
         Debug.Log(capsuleCollider.height/2 + 0.2);
         isGrounded = true;
         jumping = false;
         inAir = false;
         jumpClimax = false;
       }
    else if (!inAir)
       {
         inAir = true;
         jumpDirection = moveDirection;
       }
   
    }

 Movement ();
    Debug.Log("Execute movement!");
}
