Wow! People still use these forums. Have been using DBp for several years now but my math is pretty terrible. I'm trying to find the Y angle between 2 rotated objects with the result being relative to 1 of the objects. Basically I am making a top down space shootemup with the camera rotating around and the players ship always pointing north and I'm trying to have an arrow sprite that points towards a certain object. Now I have used Atanfull but the player Y angle (Object Angle Y) doesn't give a value between 1-360, for some reason it gives -90 to 90 and then back again which means I can't use it in the calculation?
