I've been trying to work on a system whereby the player character is able to both move around the screen using the WASD keys while also always be facing towards the position of the mouse. What I mean by this is no matter where the sprite is on screen, it's top edge will always be looking towards wherever the mouse is located - the position of the mouse should have no impact upon it's movement, only its rotation. Incidentally, the WASD keys should have no impact upon the character's rotation, only its position.
I have been able to implement the WASD movement and the continuous character rotation towards the mouse position to work separately but I have been having difficulty with getting them both to work together at the same time (the rotation towards the mouse is supposed to be able to happen at the same time as moving around the screen).
Any help would be greatly appreciated.
