This is PlayerMovement.cs

public class PlayerMovement : MonoBehaviour
{
    //movement
    public float moveSpeed;
    Rigidbody2D rb;
    [HideInInspector]
    public Vector2 moveDir;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        InputManagement();
    }

    void FixedUpdate()
    {
        Move();
    }
    void InputManagement()
    {
        float moveX = Input.GetAxisRaw("Horizontal");
        float moveY = Input.GetAxisRaw("Vertical");

        moveDir = new Vector2(moveX, moveY).normalized;
    }

    void Move()
    {
        rb.velocity = new Vector2(moveDir.x * moveSpeed, moveDir.y * moveSpeed);
    }
}

And this is PlayerAnimator.cs

public class PlayerAnimator : MonoBehaviour
{
    //Reference
    Animator am;
    PlayerMovement pm;
    SpriteRenderer sr;
    
    
    
    // Start is called before the first frame update
    void Start()
    {
        am = GetComponent<Animator>();
        pm = GetComponent<PlayerMovement>();
        sr = GetComponent<SpriteRenderer>();
    }

    // Update is called once per frame
    void Update()
    {
        if (pm.moveDir.x != 0 || pm.moveDir.y != 0)
        {
            am.SetBool("Move" , true);

            SpriteDirectionChecker();
        }
        else
        {
            am.SetBool("Move" , false);
        }
    }

    void SpriteDirectionChecker()
    {
        if (pm.moveDir.x < 0)
        {
            sr.flipX = true;
        }
        else
        {
            sr.flipX = false;
        }    
    }
}

When pressing play i get spammed with this

"Parameter 'Move' does not exist.
UnityEngine.Animator:SetBool (string,bool)
PlayerAnimator:Update () (at Assets/scripts/PlayerAnimator.cs:33)"

even though it says line 33, the first setBool from line 27 doesn’t work either
if i disable the PlayerAnimator script the “error” stops

i tried using the print(am.GetBool("Move")); as i’ve seen someone suggested and i get this

False
UnityEngine.MonoBehaviour:print (object)
PlayerAnimator:Update () (at Assets/scripts/PlayerAnimator.cs:35)

So i guess the move function is working since my character moves on the screen but the animator doesn’t see it? since the walking animation isn’t there.

Any help?

Do you have the Move parameter in your Animator parameters? You have to ensure that it is spelled the same as the “Move” string in your code.

Yes i have it In that menu, i can toggle it on and the walking animation will start, but the error message still appears. It is spelled “Move” no spaces.

Is your Animator component assigned the correct Animator Controller? You may have multiple Controllers and have assigned the wrong one (i.e. the one without “Move”) to your Animator.

I think you mean these?

I don’t know what you mean by “controller” which one is it

Check the Controller variable in your Animator component (not the Window, the component on the GameObject). You probably assigned the wrong Controller asset to it.

The right controller is set.

I messed with some options and in the parameter field i can see that when moving, the animator never leaves the “idle” state so the problem is the whole move condition. And it never switches to move = true

Can you double click on the Animator to open it and check just in case? The only way I can see that the “Parameter doesn’t exist error” occurs is if the Parameter is not in the Controller.

“plyaer” is the name of the character ( i typed it wrong and didn’t change it)

What happens when you double click into this plyaer object?

By the way, when you want to embed Imgur images, just paste the link on your post like this:

It will automatically convert the link to an Imgur image. You don’t need to copy the embed code from Imgur — that will get your post flagged as spam.

if you mean double clicking into that field, it just opens the animator window that i posted.

This is what i see if i click on the dot to change the controller:

Double clicking on the character in the scene window doesn’t do anything

Well, it looks like “plyaer” isn’t my character, it is placed in the Animations Folder and it says “(Animator Controller)” in the inspector window

Hi Mike, if your issue is still not fixed, I’m gonna need to see your project files to pinpoint your issue. I’m not sure why the error is popping, because everything seems to be set up correctly on your end.

Can you upload your files onto Drive and share the link here?

Mike, in your Animator Controller, you defined the “move” parameter, but you are trying to access the “Move” parameter in your code — Animator parameters are case sensitive so you have to make sure the spellings match.

So there wasn’t even a problem in the code, just the little thing that i had to double click and capitalize the “m”

It works now thanks for the help. I know i wrote “move” in the code and then changed it when i saw he edited his code off camera in the video.
