    line collision

    I have an alien that shoots a laser. A line is drawn from the alien xy to the botom to represent the laser, but how do I check for collision?

    yes, learn about vectors. They are easy in 2D and 3D. You a plane intercept equation to determine where two planes intercept one another. This is how "real" games do it, after they've done a brute force check for bounding-box collision, or HSR culling.
