Hello guys, i am a beginner in unity2d, im following a tutorial on youtube, but i came across an error on the argument ‘moveDir’ i get the message “Cannot convert type UnityEngine.Vector2’ expression to type float’”, please help me to solve this error, all i want is to make animation when the character moves… THANK YOU

  public int moveSpeed;
    public int jumpheight;
    private Animator _anim;

    Rigidbody2D rb2d;


	// Use this for initialization
	void Start () {
        rb2d = GetComponent<Rigidbody2D>();
        _anim = GetComponent<Animator>();
	
	}
	
	// Update is called once per frame
	void Update () {
        Vector2 moveDir = new Vector2(Input.GetAxisRaw("Horizontal")* moveSpeed, rb2d.velocity.y);
        _anim.SetFloat("Speed", moveDir);
        rb2d.velocity = moveDir;
       

        if (Input.GetAxisRaw("Horizontal") == 1)
        {
            transform.localScale = new Vector3(1, 1, 1);
        }
        else if (Input.GetAxisRaw("Horizontal") == -1)
        {
            transform.localScale = new Vector3(-1, 1, 1);
        }

        if (Input.GetKeyDown(KeyCode.Space))
        {
            rb2d.AddForce(new Vector2(0, jumpheight));
        }

So moveDir is actually a Vector2. It can’t implicitly convert to a float. “moveDir” actually has an x and a y. Both are floats, so it can’t implicitly convert to a float because it doesn’t know what you want, and it can’t know, you need to specify. Based on the fact that you’re using the “Horizontal” axis I’m assuming that the animation is tied to your x-axis movement. So try modifying the following two line:

         _anim.SetFloat("Speed", moveDir);

and modify “moveDir” to:

         _anim.SetFloat("Speed", moveDir.x);

This will tell the compiler that you want to use the x direction of the Vector2 that was made. You can later use the y-direction for jumping or falling. Or any kind of combination you want to come up with. :smiley:
