Trouble with line collision

[TheBigCheese]

I have code for a line based platformer. The code I wrote works fine until you get to the intersection between two lines, where you fall through. (The lines are all connected). In many tutorials I have seen, they also have this problem. How can I keep the player from moving through the cracks?

make them overlap by 1 pixel?

I tried that. It still goes through.

[realMakc]

by 2 pixels then?.. no, really, noone can't debug code without even seing it. and if you do paste your code, I will find another excuse, such as "this is math & phi not help me find a bug in my code forum".

never mind, I figured it out.
