Well, changing the update url for starters :P
I'll also maybe be adding timestamps to TPTMP, and possibly an anti-aliased line tool if I can get it to work well.
Okay, thanks to @wolfy1339 I finally have it working with LuaJIT - scripts should run at least twice as fast on my mod. I can't compile it for Windows for some reason, but I'll release it once I do.
EDIT: The update is completely released. Along with a 200-500% speed increase for Lua, it has a new element - HEAT- that can be used to control the temperature of surrounding particles.
Update: My previous estimates were wrong; it actually runs Lua nearly 10x faster than standard TPT. For a speed tester I used, my mod took 0.018 seconds, while normal TPT takes about 0.94 seconds.
EDIT: Sorry for triple-posting, I could have sworn I'd seen someone else post.
I was testing the speed of a benchmarking script (mostly processing arrays, but doing some other stuff too), on my mod and on the official TPT build.
That's a good idea, I'll try it later.
I tested it on various scripts people made, pretty much no difference at all...
