Character WASD Movementn Issue

Unity Engine
1

Hello, I’m building a 3D RPG game and I’m implementing the asset called KAM3RA.
I’m having trouble stopping the character from moving left and right, I just want the camera to move left and right.

So here’s the player script because I believe this is the problem.

However I can’t find anything in there that references to the A or D key.

// ThirdPersonWalker.js

// this script adds two things to the default FPS walker
// - It adds movement forward by holding down both mouse keys
// - and it adds auto animation changing between idle, walk and run
// After adding this script to your controller, drag the character model to Target

var speed = 6.0; // standard running speed
var walkSpeed = .8; // walk speed adjust both for your charcter so feet don't slide on ground
var jumpSpeed = 8.0;
var gravity = 20.0;
var Character : Transform;

private var moveDirection = Vector3.zero;
private var grounded : boolean = false;
// a flag to determine idle vs walking/running (so animations do not get started over and over)
private var walking : boolean = false;
// a flag to init idle animation at beginning
private var startup : boolean = true;
// a flag to determine walking vs running
private var running : boolean = true;

function FixedUpdate() {
if (grounded) {
// We are grounded, so recalculate movedirection directly from axes
moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));

// if both mouse buttons are down, move forward
if (Input.GetMouseButton(0) && Input.GetMouseButton(1))
{
moveDirection.z = 1;
}

moveDirection = transform.TransformDirection(moveDirection);
if(running == true){
moveDirection *= speed;
} else {
moveDirection *= walkSpeed;
}

if (Input.GetButton ("Jump")) {
moveDirection.y = jumpSpeed;
}

// auto toggle between idle and walking animations - based on run / walk switch
if(Character){
// toggle between walk and run with <left shift> R
if(Input.GetKey(KeyCode.LeftShift) && Input.GetKeyDown(KeyCode.R)){
if(running == true) {
running = false;
if(walking == true) Character.animation.CrossFade("walk");
} else {
running = true;
if(walking == true) Character.animation.CrossFade("run");
}
}
if(startup == true){
startup = false;
Character.animation.Play("idle");
}
if((moveDirection == Vector3.zero)&&(walking == true)){
walking = false;
Character.animation.CrossFade("idle");
} else {
if((moveDirection != Vector3.zero)&&(walking == false)){
walking = true;
if(running == true){
Character.animation.CrossFade("run");
} else {
Character.animation.CrossFade("walk");
}
}
}
}
}
// Apply gravity
moveDirection.y -= gravity * Time.deltaTime;

// Move the controller
var controller : CharacterController = GetComponent(CharacterController);
var flags = controller.Move(moveDirection * Time.deltaTime);
grounded = (flags & CollisionFlags.CollidedBelow) != 0;
}

@script RequireComponent(CharacterController)

Use the controller provided by unity instead?

The reference to the A and D keys are inside the axis named “Horizontal” Look up Input Axis on unity to learn about them. What it does is use two keys you give the axis, in this case a and d, one is the negative side of the axis and the other is the positive. In this case a is probably negative and d is position. Input.GetAxis returns a float between -1 and 1. If you press the negative key, a, the number returns quickly turns to -1, if you press d, it moves to 1. the is just a faster way of doing things. Instead of putting:

if(Input.GetKey(KeyCode.A))
{
     if(-speed <= maxSpeed)
          speed -= 0.1 * Time.deltaTime;
}
if(Input.GetKey(KeyCode.D))
{
     if(speed <= maxSpeed)
          speed += 0.1 * Time.deltaTime;
}
player.position.x += speed;

You can just put:

var xSpeed = Input.GetAxis("Horizontal");
var zSpeed = Input.GetAxis("Vertical");
player.position += (xSpeed, 0, ySpeed);
