YOU MUST USE FLASH! (or else lines wont draw) I'm trying to make some good advanced player physics and I needed some line segment intersection checks using only maths and position inputs, so I made this. If you have a better (faster) solution to this, then please do tell. Move the points around to see where the lines intersect. You may use this for your projects if you wish(however it may take a long time to change all the sensor blocks for getting the positions of the points, do it at your own risk xD).
