Player Walking Through Walls

Unity Engine

Please note that I am only using the forum, opposed to the answers, because it seems not to be working at the moment. Sorry if this is not what the forum is meant for (I actually have never used it before).

Hello everyone,
I have a square character, that walks around the scene. I do not want to use character controller for a number of reasons, also I do not want to use rigidbody. To keep the character from walking through walls I have been using:

var fwd = transform.TransformDirection (Vector3.forward);
var right = transform.TransformDirection(Vector3.right);
var left = transform.TransformDirection(Vector3.right * -1);
var back = transform.TransformDirection(Vector3.forward * -1);
var down = transform.TransformDirection(Vector3.up * -1);
var up = transform.TransformDirection(Vector3.up);
if (Physics.SphereCast (transform.position, gameObject.width, up, hit, 0.01)) {
MoveUp = false;
}else{
MoveUp=true;
}
if (Physics.SphereCast (transform.position, 1, gameObject.width, hit, 0.01)) {
MoveDown = false;
IsGrounded = true;
}else{
MoveDown = true;
IsGrounded = false;
}
if (Physics.SphereCast (transform.position, 1, gameObject.height, hit, 0.01)) {
MoveForward=false;
}else{
MoveForward=true;
}
if (Physics.SphereCast (transform.position, 1, gameObject.height, hit, 0.01)) {
MoveRight=false;
}else{
MoveRight=true;
}
if (Physics.SphereCast (transform.position, 1, gameObject.height, hit, 0.01)) {
MoveLeft=false;
}else{
MoveLeft=true;
}
if (Physics.SphereCast (transform.position, 1, gameObject.height, hit, 0.01)) {
MoveBack=false;
}else{
MoveBack=true;
}

Suddenly, (I am not exactly sure what) this stopped working.
I also tried:

function OnCollisionEnter(hit : Collision)
{

    if (hit.transform.position.x > transform.position.x) {
    MoveRight = false;
    
    } 
	if(hit.transform.position.x < transform.position.x){
	MoveRight = false;
	
    }

    if (hit.transform.position.y > transform.position.y) {
	MoveUp = false;
    }
    if(hit.transform.position.y < transform.position.y){
	MoveDown = false;
	IsGrounded = true;
    }

    if (hit.transform.position.z > transform.position.z) {
    MoveForward = false;
    }
	if(hit.transform.position.z <transform.position.z){
	MoveBack = false;
	}
    }
    
function OnCollisionExit(hit:Collision){
if (hit.transform.position.x > transform.position.x) {
    MoveRight = true;
    
    } 
	if(hit.transform.position.x < transform.position.x){
	MoveRight = true;
    }
    if (hit.transform.position.y > transform.position.y) {
	MoveUp = true;
    }
    if(hit.transform.position.y < transform.position.y){
	MoveDown = true;
	IsGrounded = false;
    }

    if (hit.transform.position.z > transform.position.z) {
    MoveForward = true;
    }
	if(hit.transform.position.z <transform.position.z){
	MoveBack = true;
	}
}

Neither of these seem to be working.
All help is apprectiated,
Thanks,

The Spherecast will eat performance. Do you mind explaining why you don’t want to use rigid body or character controller. Perhaps the reasons you don’t can be averted by some script or parameter in the inspector.

I find that they are too locked up. They just are not as editable as my own code is. I know you can change the character controller scripts but, I always like to make my own. In the long run I think that it will probably be easier for me.

You can just write a CharacterController script from scratch, but still use the CC component, as it comes with all the collision stuff built in.
