movePoint.position += new Vector3(Input.GetAxisRaw(“Horizontal”), 0f, 0f); VS movePoint.position += new Vector3(Input.GetAxisRaw(“Vertical”), 0f, 0f); As you might notice, you are setting the x value of the vector3 on both cases. So you move in the x direction when using up/down and when using left/right. If you want to move forward on the z-axis, you need to assign the vertical input to the z-component of the vector3 and not the x component.
