Yes shortest way round and No, for that we need the RotateSprite(sprite_id, amount) but I figured SetSpriteAngle(sprite_id, GetSpriteAngle(sprite_id)+amount) is not to painful to type out anyway so not much point in adding it?
Its to easy to go overboard and add in loads of unneeded functions, 102 flavours of CreateSprite and 19 angle functions are just not needed, I thought those 4 functions would save some headaches for the noobs and my make my own life a little easier.
And the full C++ test code for the 4 functions, it creates 2 parent sprites and attaches a bunch of child sprites to each parent with FixSpriteToSprite, one will follow the mouse on the x axis on left button, the other will follow the mouse on the y axis on the right button, 1 parent is setup to use sprite offset the other is not, this was for testing the internal code.
