"transform.Translate" doesn't works
I have to set the control setting for a sprite in Unity 2d. It should be simple: "w" and "s" to move back and forth, "a" and "d" to rotate the sprite. The rotation works, but it doesn't move. Here it is the script:
public float movespeed;
public float turnspeed;
void Update()
{
if (Input.GetKey(KeyCode.W))
{
transform.Translate(Vector3.forward * movespeed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.S))
{
transform.Translate(-Vector3.forward * movespeed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.A))
{
transform.Rotate(new Vector3(0, 0, turnspeed) * Time.deltaTime);
}
if (Input.GetKey(KeyCode.D))
{
transform.Rotate(new Vector3(0, 0, -turnspeed) * Time.deltaTime);
}
}

Because you have a 2D game you have to use Vector3.right instead of Vector3.forward. The latter vector moves your gameObject on the Z axis. However, in 2D, you only work with the (XY) plane...
if (Input.GetKey(KeyCode.W))
{
transform.Translate(Vector3.right* movespeed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.S))
{
transform.Translate(-Vector3.right* movespeed * Time.deltaTime);
}
Good day.
Whats the value of movespeed and turnspeed? Its a 2D game right? what are the planes you are using? maybe forward is set to "up" so it will not move, i recomment you to write the Vector the same way you did in the rotation (0, 0, movespeed) or (0, movespeed, 0) or (movespeed, 0, 0)
Bye!
