Regarding DontGoThroughThings.js still allowing character to run through walls

Hi all, I have some problems regarding the usage of DontGoThroughScript.js. When I attach the script to my model, It still run through the collisions.

Then I try to include the codes within the control script for the character’s movement, and the problem still the same. Here is my script:

var spd = 0;
var layerMask : LayerMask;
var skinWidth : float;
var minExt : float;
var partialExt : float;
var sqrMinExt : float;
var previousPos : Vector3;
var body : Rigidbody;

function Awake() {
	body = rigidbody;
	previousPos = body.position;
	skinWidth = 0.1;
	minExt = Mathf.Min(Mathf.Min(collider.bounds.extents.x, collider.bounds.extents.y), collider.bounds.extents.z);
	partialExt = minExt*(1.0-skinWidth);
	sqrMinExt = minExt*minExt;
}

function FixedUpdate() {
	var movement : Vector3;
	var movementSqr : float;
	movement = body.position - previousPos;
	movementSqr = movement.sqrMagnitude;
	
	if (movementSqr > sqrMinExt) {
		var movementMag : float;
		var hit : RaycastHit;
		
		movementMag = Mathf.Sqrt(movementSqr);
		
		if (Physics.Raycast (previousPos, movement, hit, movementMag, layerMask.value)) {
			body.position = hit.point-(movement*movementMag)*partialExt;
		}
	}
	previousPos = body.position;
	
	var dir : Vector3 = Vector3.zero;
	
	dir.z = Input.acceleration.x + 0.7;
	
	if (Input.acceleration.y <= -0.2 && Input.acceleration.y >= -1){
		transform.Rotate(0,-Input.acceleration.y*2,0);
	} else if (Input.acceleration.y >= 0.2 && Input.acceleration.y <= 1){
		transform.Rotate(0,-Input.acceleration.y*2,0);
	} else {
		transform.Rotate(0,0,0);
	}
	
	if (Input.acceleration.x <= -0.8){
		spd = 0;
		animation.Play("idle");
	} else if (Input.acceleration.x > -0.8 && Input.acceleration.x <= -0.5){
		Debug.Log("walk");
		spd = 5;
		animation.CrossFade("walk");
	} else if (Input.acceleration.x > -0.5 && Input.acceleration.x <= -0.2){
		Debug.Log("run");
		spd = 10;
		animation.CrossFade("run");
	} else if (Input.acceleration.x > -0.2){
		spd = 15;
		Debug.Log("sprint");
		animation.CrossFade("run");
	}
	
	if (dir.sqrMagnitude > 1) {
		dir.Normalize();
	}
	
	dir *= Time.deltaTime;
	transform.Translate (dir * spd);
	Debug.Log(dir);
}

Thanks in advance!

Well, it’ll never work, because you are basically going like this-

  1. Fix up the movement so that it doesn’t go through walls
  2. Ignore that, and just move the old way anyway!

You need to put the bit that fixes collisions after your movement bit, not before it! You basically need to put everything between ‘movement = body.position - previousPos;’ and ‘previousPos = body.position;’ after ‘Debug.Log(dir);’.
