Colliding with GDI+

I'm having some difficulties with a game. It's kinda like CurveFever (Achtung Die Kurve), but I just want it for personal 1P usage. The problem is just that I can't figure out a way to check if the line is colliding with any point of where it has been before. I know there are lots of ways to do it, but I always end up with the game running slow because of bad methods such as searching for pixels etc. Any suggestions on a faster method? (You would probably have to test the code yourself to know what I'm saying if you want to help :/ )

TheNorwegianUser, you have been around long enough now that you should have read the Forum Rules (bottom right of every page). I would highly suggest you read them now, especially the part regarding Game Automation and Interaction (mainly because it's lame).

JLogan3o13,

This script is the embryo of a game written in AutoIt by the OP and as such is entirely legal. :)

Sorry, I was apparently too hasty. :)

I thought we'd backed off on even AutoIt-developed games (the "regardless of the game" segment in the rules). My apologies to the OP.

You can try to use _GDIPlus_BitmapGetPixel():
