Movement issues with keyboard

Hello, my first question, so not sure if it is too over asked, but I really need some help.

So, I’m making a top down game, and I have movement code below, and the diagnol movement is faster than the crossWay moving. Any ideas? Thanks a million guys it would help a lot


public float speed;
    public Vector2 position;

    public void Update()
        transform.position = position;

    public void CheckInput()
        if (Input.GetKey(KeyCode.W))
            position.y += 1;
        if (Input.GetKey(KeyCode.S))
            position.y -= 1;
        if (Input.GetKey(KeyCode.A))
            position.x -= 1;
        if (Input.GetKey(KeyCode.D))
            position.x += 1;

There are two ways to do this:

if(Input.GetKey (KeyCode.W))
	transform.position = new Vector3(transform.position.x, transform.position.y + 1, transform.position.z);

if(Input.GetKey (KeyCode.S))
	Vector3 nextPosition = transform.position;
	nextPosition.y -= 1;
	transform.position = nextPosition;

For a detailed explanation why: Unity official tutorials - Data Types

In short: You cannot modify your position value, because it is only a copy of transform.position. Instead modify transform.position. Secondly, you cannot modify transform.position.y directly, because it only returns a copy of the value, not the actual reference to the object transform. You have to assign a whole new Vector3 to transform.position to change it.

It seems to me that you need to normalize diagonal movement using Time.deltatime…

You move left, right, forward or backwards one unit at a given time, but to move diagonal you need to traverse two units in the same amount of time. Hence, the additional speed perceived.
