How to set joystick for movement

[Amberlewis012]

Hello, how can I set a joystick from those on the asset store or just normal buttons to replace these actions on a mobile device? I’ve been struggling to integrate them and I’m quite new to all this as well. Also, if you have any ideas on how to make this code better, then hope you can help me as well. Thanks a lot!

public Rigidbody rb;
public float moveForce = 5f;
   
void Update()
{
    if (Input.GetKey("d") || (Input.GetKey(KeyCode.RightArrow)))
    {
        rb.AddForce(moveForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }
    if (Input.GetKey("a") || (Input.GetKey(KeyCode.LeftArrow)))
    {
        rb.AddForce(-moveForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }
    if (Input.GetKey("w") || (Input.GetKey(KeyCode.UpArrow)))
    {
        rb.AddForce(0, 0, moveForce * Time.deltaTime, ForceMode.VelocityChange);
    }
    if (Input.GetKey("s") || (Input.GetKey(KeyCode.DownArrow)))
    {
        rb.AddForce(0, 0, -moveForce * Time.deltaTime, ForceMode.VelocityChange);
    }
    if (Input.GetKey("e"))
    {
        transform.Rotate(Vector3.up * speed * Time.deltaTime);
    }
    if (Input.GetKey("q"))
    {
        transform.Rotate(Vector3.down * speed * Time.deltaTime);
    }

First of all, youre using a lot of unnecessary ifs. You can just use Input.GetAxis("Horizontal") to get left arrow and right arrow, and same for vertical axis. Nevertheless, using the free joystick pack in the unity asset store, you can access a class containing the types of joysticks available. Im using the variableJoystick class in this case but you can use any of the different types of joysticks. So you can basically write:

    public VariableJoystick moveJoystick;
    public VariableJoystick lookJoystick;
    //Two joystick references, one for movement and one for looking around

    public Rigidbody rb;
    public float moveForce = 5f;
    public float speed = 5f;

    private void Update()
    {
        float x = moveJoystick.Horizontal; //Equals the joystick handle's position from the center of the joystick on the horizontal axis
        float z = moveJoystick.Vertical; //Equals the joystick handle's position from the center of the joystick on the vertical axis

        float y = lookJoystick.Vertical;

        Vector3 moveDirection = transform.right * x + transform.forward * z; //Direction of movement
        Vector3 lookDirection = new Vector3(0, y, 0); //Direction of look rotation

        rb.AddForce(moveDirection * Time.deltaTime, ForceMode.VelocityChange); //Constantly adds force depending on where the handle of the joystick is 
        transform.Rotate(lookDirection * speed * Time.deltaTime); //Looks in the right direction depending on the other joystick's y position
    }

This uses two VariableJoystick’s. One for movement and the other for the look controls. These classes are only available from the free joystick asset pack on the unity asset store. Hope it helps @Amberlewis012

Ok so I tried putting the code in the player script, however it doesn’t allow me to put the joystick in the move joystick slot thing, and if I put in the joystick from the prefab it allows me to do it but doesn’t do anything when I play. What did I do wrong or is it because my player is not in the actual scene or something? Thanks a lot for helping anyways @Llama_w_2Ls
(also just realised this isn’t a reply but whatever it works)

can you tell me where i can place this public VariableJoystick moveJoystick;
public VariableJoystick lookJoystick;
//Two joystick references, one for movement and one for looking around

 public Rigidbody rb;
 public float moveForce = 5f;
 public float speed = 5f;

 private void Update()
 {
     float x = moveJoystick.Horizontal; //Equals the joystick handle's position from the center of the joystick on the horizontal axis
     float z = moveJoystick.Vertical; //Equals the joystick handle's position from the center of the joystick on the vertical axis

     float y = lookJoystick.Vertical;

     Vector3 moveDirection = transform.right * x + transform.forward * z; //Direction of movement
     Vector3 lookDirection = new Vector3(0, y, 0); //Direction of look rotation

     rb.AddForce(moveDirection * Time.deltaTime, ForceMode.VelocityChange); //Constantly adds force depending on where the handle of the joystick is 
     transform.Rotate(lookDirection * speed * Time.deltaTime); //Looks in the right direction depending on the other joystick's y position
 }

player or canvas???
