Isometric movement using arrow keys?

Hello,

If you would not like to use rigidbody / character controller you can something like this:

 //Javascript
 var moveForward:boolean;
 var moveBack:boolean;
 var moveRight:boolean;
 var moveLeft:boolean;
 var speed:float;
 
 function Update(){
 if(MoveForward){
 transform.position += transform.forward * speed * Time.deltaTime;
 }
 if(MoveBack){
 transform.position += -1 * transform.forward * speed * Time.deltaTime;
 }
 if(MoveRight){
 transform.position += transform.right * speed * Time.deltaTime;
 }
 if(MoveLeft){
 transform.position += -1 * transform.right * speed * Time.deltaTime;
 }
 }
 
 function OnCollisionEnter(hit:Collision){
 if(hit.gameObject.transform.position.z > transform.position.z){
 MoveForward = false;
 }
 if(hit.gameObject.transform.position.z < transform.position.z){
 MoveBack = false;
 }
 if(hit.gameObject.transform.position.x > transform.position.x){
 MoveRight = false;
 }
 if(hit.gameObject.transform.position.x < transform.position.x){
 MoveLeft = false;
 }
 }
 
 function OnCollisionExit(hit:Collision){
 if(hit.gameObject.transform.position.z > transform.position.z){
 MoveForward = true;
 }
 if(hit.gameObject.transform.position.z < transform.position.z){
 MoveBack = true;
 }
 if(hit.gameObject.transform.position.x > transform.position.x){
 MoveRight = true;
 }
 if(hit.gameObject.transform.position.x < transform.position.x){
 MoveLeft = true;
 }
 }

If this doesn't work or you are using rigidbody or character controller please let me know.
