Can only move forward or back, no left or right.

This is really strange, I am very very new to programming so be patient and bear with me please.

As the title says I can only move my character forward or back and not sideways, the funny thing about this is that I don’t want him to move forward or back I want only side ways.

It is the basic 2d space shooter you would expect.

I have tried two sets of code, first is below:

`var speed : float = 3;
var projectile_prefab: GameObject;

function Update ()
{
var translationX : float = Input.GetAxis (“Horizontal”) * speed;

var translationZ : float = Input.GetAxis (“Horizontal”) * speed;

translationX *= Time.deltaTime;
translationZ *= Time.deltaTime;
transform.Translate (translationX, 0, translationZ);

if(Input.GetKeyDown(“space”))
Instantiate(projectile_prefab);
}`

The other set of code I tried was:

`var moveSpeed = 1.0;
var turnSpeed = 1.0;

function Update()
{
/*
if(Input.GetButtonDown(“Jump”))
{
transform.position.z += 1.0;
}
*/

if(Input.GetButton("Forward"))
{
	transform.position += transform.forward * moveSpeed * Time.deltaTime;
}
if(Input.GetButton("Backward"))
{
	transform.position += -transform.forward * moveSpeed * Time.deltaTime;
}
if(Input.GetButton("Left"))
{
	transform.eulerAngles.y += -turnSpeed * Time.deltaTime;
}
if(Input.GetButton("Right"))
{
	transform.eulerAngles.y += turnSpeed * Time.deltaTime;
}

}

if(Input.GetKeyDown(“space”))
Instantiate(projectile_prefab);

}`

I cant understand why either of these don’t work. Any help is greatly appreciated.

Unity doesn’t like when you try to modify eulerAngles directly so first make a copy of its value into a new Vector3, apply the rotation and then set eulerAngles to it.

rot = transform.eulerAngles;
rot.z += turnSpeed * Time.deltaTime;		
transform.eulerAngles = rot;

Also, the turnSpeed of 1 is very low and you might not even notice it if its working – it’s 1 degree a second as is. So set it higher to find out if it’s working for you.
