More movement forward made today. Not massive strides, but taking one step at a time on a daily basis definitely adds up quickly. Being used to RAD development with languages like Delphi and C#, C++ development feels much slower, but simultaneously has a more gratifying feeling associated with it. Weird. I'll have to get used to it. [smile]
The basic collision system is in, supporting two levels of precision. The first checks the Manhattan distance between the sprites, skipping any further levels if the check yields a distance greater than the combined sizes of the sprites. The next level is a bounding box check, which is currently as deep/precise as it goes. I intend to add pixel-based detection later on if it's needed, but it may not be needed.
Right now the detection-checking algorithm is VERY inefficient. It simply checks each sprite against all others, so for 250 sprites that's C(250,2), which is something like 31,000 collision checks. Eee! Someone -- sooner rather than later -- I'll develop a sector/segment system that will allow sprites to only check for collisions against other potentially relevant sprites, instead of the whole batch.
Sprite Types (or Templates)
I've always wanted a nice flexible system for all of the various entities, sprites, and actors in my games. I loathe all of the hardcoding I've had to do for Skirmish Online when defining the various types of sprites (Players, Bullets, Particles, etc). Now I scribble up a text file like so:
Bam. This INI-esque format lets me define fields relatively on-the-go, so I can throw in cool stuff like particle types for the particle engine, with fields like R/G/B, alpha, blend-mode, velocity, and other goodies. All without recompiling! [smile]
(Oh, and I threw in an FPS counter for fun. Don't mind the unoptimized framerate!)
