I need some help with a formula or bit of code for finding the distance to the closest point in a line segment. Effectively, the “distance from the line segment” is going to be used as a sort of “bonding box”, so that a user can click relatively close to a line, and it count as clicking on that line.
If you’re using Swing, then you should be able to use
Line2D.ptSegDist(Point2D)or its various overloads to do all the math for you.
