The way disable the Diagonal movement (keypress AW, AS, WD, SD) of the charater in Top down 2D game!

I have this problem before, and this is my solution, you can reference it. I tested your script too, and it doesn't allow overrides. Maybe you can change it with dictionary method, but I think it good for beginner.

    var direction := Vector2.ZERO
    var move_speed = Vector2()
    if Input.is_action_pressed("move_right"):
        direction.x = 1.0
    elif Input.is_action_pressed("move_left"):
        direction.x = -1.0
    if direction.x != 0:
        move_speed.x = SPEED
        direction.y = 0
    elif Input.is_action_pressed("move_up"):
        direction.y = -1.0
    elif Input.is_action_pressed("move_down"):
        direction.y = 1.0
    if direction.y != 0:
        move_speed.y = SPEED
        direction.x = 0
    move_and_slide(SPEED * direction)

Put ```gdscript
before the code blocks, so the syntax highlighting is on

@sepTN oh, it's cool
