Terrain Collision Glitch

Questions & Answers

I created a terrain and i added my player prefab.

That done this :

My player collide with a slope, and the collision glitch.
Why?
Here’s my movement code:

#pragma strict
@Header("Statistics")
@Range(0,5)
var speed : float;
@Range(0,50)
var jumpForce : float;
var playerRigidbody : Rigidbody;
var inputAxis : Vector3;

var grounded : boolean;

@Header("OverlapSphere")
var groundSphereRadius : float;
var groundLayers : LayerMask;
var debugCollision : boolean;
var check : Vector3;
@Header("Debug")
var realSpeed : float;
var speedMultiplicator : float;
var smoothTime : float;

function FixedUpdate () {
	var horizontalDivisor : float;
	inputAxis = Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
	var realInputAxis : Vector3;
	if(Input.GetButton("Run") && grounded){
		speedMultiplicator = 2;
		horizontalDivisor = 2;
	}else if(Input.GetButton("Crouch") && grounded){
		speedMultiplicator = 0.5;
		horizontalDivisor = 1;
	}else{
		speedMultiplicator = 1;
		horizontalDivisor = 1;
	}
	
	realInputAxis = Vector3(Input.GetAxis("Horizontal") / horizontalDivisor, 0, Input.GetAxis("Vertical"));
	
	realSpeed = speed * speedMultiplicator;
	var transformedRealInputAxis = transform.TransformDirection(realInputAxis);
	playerRigidbody.MovePosition(transform.position + transformedRealInputAxis * realSpeed * Time.deltaTime);
	
	if(Input.GetButtonDown("Jump") && grounded){
		playerRigidbody.AddForce(Vector3.up * jumpForce * 25, ForceMode.Impulse);
	}
	
	var hitColliders = Physics.OverlapSphere(check + transform.position, groundSphereRadius, groundLayers);
	if(hitColliders.Length == 0){
		grounded = false;
	}else{
		grounded = true;
	}
	
	//Fake friction
	var easeVelocityFactor : float;
	easeVelocityFactor *= 0.75;
	
	playerRigidbody.velocity.x = easeVelocityFactor;
	playerRigidbody.velocity.z = easeVelocityFactor;
}

function Update () {
	
}

function OnDrawGizmosSelected() {
    if(debugCollision){
    	if(grounded){
    		Gizmos.color = Color.green;
    	}else{
    		Gizmos.color = Color.red;
    	}
    	Gizmos.DrawSphere(check + transform.position, groundSphereRadius);
    }
}

Hey @Bryckout, I guess your character doesn’t glitch on a flat terrain, does it?
Maybe the glitch is caused by low physics iterations, or, ‘resolutions.’
How about increasing it?

Go to Edit>project settings>physics
then increase the Solver Iteration Count.

See if any change occurs. But increasing the solver iteration comes with the price of computational burden, so do it wisely. And terrain seems to be unreliable when in steep angle, probably due to the resolution, but that’s only my guess.
