Why moveDirection.z doesn't work?

Question

part of the code:

             if(Input.GetButtonDown("Fire1")  &&  controller.isGrounded){
             playIdle = false;
             animation.CrossFade("CHit1",0.01);
             animation["CHit1"].speed = 0.23;
             moveDirection.z = 20;
             moveDirection = transform.TransformDirection(moveDirection);
             }

I don't see speed defined and set anywhere. Thus, by this script, it is 0, which means all your functions using speed result in 0.

Rather then just dropping your first attempt at code on others in the hopes that they will fix it, you should learn to properly debug your code.

Debugging is a matter of checking each value along the way (usually through Debug.Log) to see fi it is what yo expect it to be and, when you find the first one that isn't, ascertaining why,

$$anonymous$$y code is correct,speed is in script but it wasn't pasted in code,only moveDirection.z = 20 is not working and i don't know why?

      var speed : float = 6.0;
     var jumpSpeed : float = 8.0;
     var secondJumpSpeed : float = 15.0;
     var gravity : float = 20.0;
     var En1 : EnemySph1;
     var AirSpeedRemove : float = 2.0;
     
     private var moveDirection : Vector3 = Vector3.zero;
     private var secondJumped = false;
     private var playIdle = true;
     
     function Update() {
     
         var controller : CharacterController = GetComponent(CharacterController);
         
         transform.Rotate(0,Input.GetAxis("Horizontal"),0);
         
             if(Input.GetButtonDown("Fire1")  &&  controller.isGrounded){
             playIdle = false;
             animation.CrossFade("CHit1",0.01);
             animation["CHit1"].speed = 0.23;
             moveDirection.z = 20;
             moveDirection = transform.TransformDirection(moveDirection);
             }
             
         if (controller.isGrounded) {
             if(playIdle == true){
             animation.CrossFade("Idle");
             }
             secondJumped = false;
             moveDirection = Vector3(0, 0,Input.GetAxis("Vertical"));
             moveDirection = transform.TransformDirection(moveDirection);
             moveDirection *= speed;
             
             if (Input.GetButton ("Jump")) {
                 moveDirection.y = jumpSpeed;
                 animation.CrossFade("Jump1");
             }
         }
         else {
     moveDirection = Vector3(0, moveDirection.y, Input.GetAxis("Vertical"));
     moveDirection = transform.TransformDirection(moveDirection);
     moveDirection.z *= speed/AirSpeedRemove;
     moveDirection.x *= speed/AirSpeedRemove;
 }
 
            
          
                 if(Input.GetButtonDown("Jump") && controller.isGrounded == false && secondJumped == false){
                 moveDirection.y = secondJumpSpeed;
                 secondJumped = true;
                 animation.CrossFade("Jump2");
                 }
                 
                 if(Input.GetAxis("Vertical") && controller.isGrounded){
                 animation.CrossFade("Run");
                 if(Input.GetButtonDown("Jump")){
                 animation.CrossFade("Jump1");
                 } 
                 }
 
         moveDirection.y -= gravity * Time.deltaTime;
         
         controller.$$anonymous$$ove(moveDirection * Time.deltaTime);
     }

if(Input.GetButtonDown("Fire1") && controller.isGrounded){ playIdle = true; animation.CrossFade("CHit1",0.01); animation["CHit1"].speed = 0.23; moveDirection.z = 20; moveDirection = transform.TransformDirection(moveDirection); }

Presuming you have that in a Vector3:

var localVector = transform.InverseTransformDirection(moveDirection); You have to change the playidle flase to true just little change make it worked

Just set the y-component of your moveDirection to 0 before you use it for LookAt, or since it's a 2.5d game link, just use the z axis

// Just use the z axis transform.LookAt(transform.position + Vector3(0,0,moveDirection.z));

// Or set the y axis to 0 var tempDirection = moveDirection; tempDirection.y = 0; transform.LookAt(transform.position + moveDirection);

  moveDirection = Vector3(0, moveDirection.y, Input.GetAxis("Vertical"));
  moveDirection = transform.TransformDirection(moveDirection);
  moveDirection.z *= speed/AirSpeedRemove;
  moveDirection.x *= speed/AirSpeedRemove;
