I cant get the movement to work

Unity Engine
1

This is my first project and it has already stopped working. This is my code so can someone tell me the problem. It keeps saying error 1503
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class playermovement : MonoBehaviour {
public float movementSpeed;
public Rigidbody2D rb;
float mx;
private void Update() {
mx = Input.GetAxisRaw(“Horisontal”);
}
private void FixedUpdate() {
Vector2 movement = new Vector2(mx * movementSpeed, rb.velocity);
rb.velocity = movement;
}
}

2

mx = Input.GetAxisRaw("Horisontal");

should be

mx = Input.GetAxisRaw("Horizontal");

That’s one thing. I will try to re-create your script now…

You also are using rb.velocity as a part of the Vector2 defining rb.velocity, try instead –

Vector2 movement = new Vector2(mx * movementSpeed, transform.position.y);

A Vector2 defines 2 dimensions, the X and the Y. X corresponds with left and right in 2D space in unity while Y corresponds with your Vertical movement. So a Vector2 should be seen as –
Vector2(X,Y). If I’m understanding correctly, you’re trying to move the player only left and right at the moment, so you need to maintain the gameObject current Y position during the AddForce method.

This line:

We know Vector2() constructor takes 2 floats (see documentation).

First argument looks good: mx is float, movementSpeed is float, so good.

But your second argument is a Vector2 (again, see documentation!), so that’s not gonna work.

You need to give the Vector2() constructor 2 floats.

Ok
