The orc is coming along. I'm just kind of randomly adding different things he can do. The latest is that he can glide on his shield like Olaf from The Lost Vikings.
I think this is going to turn into a game but I'm not sure exactly what it will look like. Definitely a platformer of some sort but I'm not sure if the focus will be on action or puzzles or something in between.
I've been thinking about ways to use the crawlers that I wrote last week. Some ideas that I had were maze generation (it is out because the mazes are actually pretty lame), tile texturing (the tiles have to be really large for it to make sense), and random entity movement (not sure why this would ever be useful). Then I noticed that all of the negative space paths always touch the outside border, so if I spawned crawlers on the corners of the space I could fill in the pattern every time. So then I decided to try them with scene transitions and I really like the look. It would only work in games with a certain style and the speeds need to be adjusted because the transitions are too long now, but I'm happy with it.
So I did some quick optimization work on the exploding sprites algorithm. One of the very noticeable problems was the delay during the initial and last frame of the explosion or combination. The delay came when the PC had to write a large amount of objects to and from arrays. By introducing a random delay to the algorithm I made it so that all the pixels don't arrive at their destination at the same time so the array writes are spread out over multiple CPU cycles instead of all at once. It removed the delay at the end. I'm leaving the slight delay at the explosion because I think it is worth it to have them all go at once.
I have a couple problems to solve:

Messing around with making some exploding sprites. Sprites explode into individual pixels and can recombine to form other sprites. Right now it only works with small images because there is a LOT of calculations being done every update (each pixel gets tweened) so optimization will be key. Not sure how I want to handle this yet though.
I can do about 5000 pixels without any slowdown currently which is right around a 64x64 sprite. Needs work...
I made some changes to my crawlers. They still follow the same 6 rules as before, but I changed it so now turning and backtracking along a path no longer take up the crawlers "step", so now they all find alternate paths much faster. This was a design choice the first time, but I like it more now.
I also got rid of the hard coded step distance, so now crawlers can move any number of spaces in a step instead of just 2. I used 2 so the paths are spaced apart, but there is no reason they have to be. So now I could do a very inefficient flood fill with crawlers.
Crawlers can now change the color of the trails they leave behind.
The mouse can now spawn crawlers too. Which lets you do cool stuff.
You can play with Crawlers yourself here.
I was inspired by the cool temple wall art by MrTedders and wanted to make my own. His was done by hand, but I wanted to make something similar using the computer. I have a lot of interest in computer generated content and this case seemed like a perfect opportunity to use it.
I want to use these techniques to generate some interesting patterns for game development. Maybe not this particular pattern, but something.
I made this pattern with a bunch of what I called Crawlers. Basically a crawler is a little bug that leaves a trail behind it as it walks around and keeps track of where it has been. My crawlers follow a set of very simple rules to make their patterns:
Those 6 simple rules generate random patterns that look like this:
So this time I made the lighting maps of my entire spreadsheet and ran them through Sprite Lamp to make my normal map. This is the output from within Sprite Lamp itself since my shader I wrote isn't working on images that aren't square and its too late to fix it...
The Sprite Lamp process for making this normal map was about 40 minutes. I found some shortcuts as I went along so I could probably do it in the future in about 25 or so...
