Welcome to this week’s From the Forum. In this post, we highlight a few Corona Community Forums posts that cover important topics.

Deriving points

Math is important! In this thread, the poster knows two points on a line but wants to calculate points along a circle for which that line is a radius. Several of our brightest developers jumped in with multiple math, code and working examples.

Wavy movement

Curves have always challenged developers regardless of platforms. Moving your enemies in a straight line… easy peasy… Moving them in a wave takes a bit more math. This thread contains some great examples on moving objects along a wave.

Controlling body movement

The poster of this thread noticed that when two physics objects interact, one object that was expected to stay in place had some slight movement. The problem was analyzed and a solution offered.
