It is the same as calculating the derivative of a function to determine the slope of a tangent point. Very simple! www.itoady.com A* (A-star) Searching Algorithm - A.I.

WeMartiansAreFriendly 2 Posted April 2, 2007 Share Posted April 2, 2007 That is just too simple... would you have prefered it to be over 100 lines, or a full blown #include? Don't bother, It's inside your monitor!------GUISetOnEvent should behave more like HotKeySet() Link to post Share on other sites
