Yup. I need the player, at a constant coordinate of 400, 300, to face the mouse. And i suck at stuff like this? Any help?

rotation degrees = 0 when facing right. Up is 270. ect…

    float radiansToMouse = (float) Math.atan2(400 – input.getMouseX(), 300 – input.getMouseY());
    float degreesToMouse = (57.2957795f * radiansToMouse) * -1;
    heroImage.setRotation(degreesToMouse);

    Something like this?
