Why won't my unity controller work properly?

Question

I'm new to unity and I am facing problems with the animator controller component.

When pressing on Z button, my player is supposed to start moving forward, but the animation won't start.

Here is my code:

public Animator anim;

// Start is called before the first frame update
void Start()
{
    anim = GetComponent<Animator>();
}

// Update is called once per frame
void Update()
{
    if (Input.GetKey(KeyCode.Z))
    {
        anim.SetFloat("MoveX",0.17f);
        Debug.Log("hhh");
    }
    else
    {
        anim.SetFloat("MoveX", 0);
    }

    if (Input.GetKey(KeyCode.Q))
    {
         anim.SetFloat("MoveZ",0.208f);
         Debug.Log("stiw");
    }
    else
    {
        anim.SetFloat("MoveZ", 0);
    }

    if (Input.GetKey(KeyCode.S))
    {
        anim.SetFloat("MoveX",-0.166f);
    }
    else
    {
        anim.SetFloat("MoveX", 0);
    }

    if (Input.GetKey(KeyCode.D))
    {
        anim.SetFloat("MoveZ",-0.2f);
    }
    else
    {
        anim.SetFloat("MoveZ", 0);
    }
}

Moving backward and starting right works properly, except moving forward and moving to the left

Well look at your conditions in Update again and think what happens if you press the forward button (Q):

• first you set anim.SetFloat("MoveZ",0.208f);
• BUT : this means that you are not pressing backwards (D) so you set anim.SetFloat("MoveZ",0);

see it now? The last two checks overrule the first two and "eat" you input;)

You should make your cases more exclusive like eg

void Update()
{
    if (Input.GetKey(KeyCode.Z))
    {
        anim.SetFloat("MoveX",0.17f);
        Debug.Log("hhh");
    }
    else if (Input.GetKey(KeyCode.S))
    {
        anim.SetFloat("MoveX",-0.166f);
    }
    else
    {
        // Only reached if neither Z nor S is pressed!
        anim.SetFloat("MoveX", 0);
    }

    if (Input.GetKey(KeyCode.Q))
    {
         anim.SetFloat("MoveZ",0.208f);
         Debug.Log("stiw");
    }
    else if (Input.GetKey(KeyCode.D))
    {
        anim.SetFloat("MoveZ",-0.2f);
    }
    else
    {
        // Only reached if neither Q nor D is pressed!
        anim.SetFloat("MoveZ", 0);
    }
}
