Re: New widget: Enemy Spotter

Guess I have to do this the hard way. People can test the entire set of optimizations vs. your code.
This is the very last time I will help you, though, I don't help people who don't want to learn, and your attitude sucks.
Put the attached file into /bitmaps.
For advanced folks, there is at least one speedup left (and, ofc, if you don't like the circles clipping the ground, feel free to change that glDepthTest to false, it's that way because of other things in P.U.R.E.).
