This could be used for example for shooting. In the picture the teapot is always in the middle of the screen (with 500px y-offset). With mouse click, entity should be created at the position of the teapot and fly towards the mouse pointer. I have figured out one solution using just mathematic functions, but it is quite ugly code. Is there any game studio function to achieve this? Thanks in advance. Last edited by wolodo87; 07/26/10 12:57.
