I tried playing around with water effects. This first one is a pretty standard cellular water effect.

I was messing around with the settings and got this really fun effect.

The tough bit is getting the water to distribute in a way that no water is lost or gained. Haven’t quite figured out how to do that yet. The basic effect really gives “infinite” water and just models the waves.

I spent a bit more time fooling around with my light / shadow engine. Got it running nice and fast with a ton! Changed the colors to make it look better.

This shot has about 200 moving light sources.

I put together a lighting engine this week.  It took a lot of coding before I could really test anything.

My first test effort I just rendered things as boxes to ensure that I even had the correct data.

Next I did some ray casting so I could see if I got that working.

Lastly I rendered those rays using a triangle fan.

I found that the CPU was being maxed out pretty bad, it turns out my first step (showing the boxes) was using the most. So I turned those off and things ran at a nice clip.

So I spent some time adding time rewind to a simple breakout style game.  Once you miss a ball, it rewinds a few seconds.

The rewind worked, but I didn’t feel it really added much to the breakout experience.  It would do just as well to just give the player more balls.  While creating this prototype, I named the folder “breakwind” and only an hour or so later did I realize the double meaning.  I’m not sure if that makes it the best or worst game name idea I’ve ever had.

Part of the trick of time rewinding is to have as little state as possible.  This fire effect is generated from just this:

I’ve been playing around with various prototypes over the past few months.  I decided I might as well start sharing what I’m doing.  Gifs are easy to make!

I made some simple time rewinding code the other day.  I’m pretty pleased with how it came out.  I updated it with fancier particles and a slightly different pattern and got a really neat effect:

Anyway, hope to make some more fun prototypes off this concept.  We’ll see!
