If you've never seen this kind of thing before, the canonical PC example is The Powder Toy, which is so amazing I wish there a 3D Minecraft-like version. But it's really CPU-heavy even in 2d.

- dTal 8y agoI think the CPU load is just inherent to the type of program it is. It's running a fluid dynamics simulation, a thermal dynamics simulation, Newtonian gravity simulation, and discrete particle simulation all at once. If you made all that in 3D, you would have made an incredibly amazing game engine that no computer could possibly run.
- macawfish 8y agoOh, I meant to get solids conducting heat ;p
- make3 8y agoalso.. mites don't reproduce..
- DDR0 8y agoTry feeding them dust.
- swirepe 8y agoand water doesn't pool
- kristianp 8y agoand the water turns into plants as fast as fire burns the plants.
- jabl 8y agoAnd the water seem spectacularly incapable of putting out fires.
- heavenlyblue 8y agoThere's no way to put out a fire burning on top of the cloner.
- heavenlyblue 8y agoI mean - if you already managed to put plants in the cloner.
- mml 8y agodissolve the cloner in acid
- db48x 8y agoThey do eat wood though.
- Narretz 8y agoThey also can't be drowned, or killed by lava or acid.
- delinka 8y agoSelect Wall. Draw "bowl". Select Water. Drop water into bowl. Select Cloner. Click beneath bowl. Select Fire. Click beneath Cloner. Observe boiling water.
- perlgeek 8y agoInteresting, I can boil water with fire directly. But when I put oil (in a separate compartment) beneath the bowl of water, and light it on fire, the oil burns off, but doesn't boil any water.
- ricardobeat 8y ago> Observe boiling water What should happen? All I see is the surface 'sparkle' effect that is the same as still water.
- tbirrell 8y agoThe water eventually disappears.
- Asraelite 8y agoAre you sure? I tried watching a few different setups for a while and the water level never seemed to change. Even applying fire directly to water doesn't have an effect.
- delinka 8y agoThis is what should happen: https://youtu.be/hW6_iA_YAOo https://youtu.be/hW6_iA_YAOo
- comice 8y agoboiling some water was pretty much the first thing I tried too! was disappointed. still great though.
- Impossible 8y agoI did a ton of research because I was looking into creating a VR falling sand game (which someone actually made about a year ago https://www.oculus.com/experiences/rift/1337446473017832/ https://www.oculus.com/experiences/rift/1337446473017832/). There are a couple of other 3D falling sand games (http://csiuo.com/Sand3d/ http://csiuo.com/Sand3d/, https://github.com/TheTomster/sandish https://github.com/TheTomster/sandish, https://powdertoy.co.uk/Discussions/Thread/View.html%3FThread%3D10534 https://powdertoy.co.uk/Discussions/Thread/View.html%3FThrea...) but none of them are very good due to the factors you mentioned. UX is also a pretty big problem, as traditional mouse or touch controls don't work well in 3D, which is why I wanted to go the VR route, but something like a very dynamic Minecraft as you mentioned could work as well. Most falling sand game implementations are sequential, so parallelizing the simulation using a margolus neighborhood (https://en.wikipedia.org/wiki/Block_cellular_automaton https://en.wikipedia.org/wiki/Block_cellular_automaton) or double buffer could greatly improve performance. Most falling sand games tend to not be pure cellular automata, and some are implemented as particle systems with particle in cell grid collision instead of CA, but particle and fluid sims are easy to parallelize. I haven't seen a falling sand game (2D or 3D) that runs entirely on the GPU, and my goal was to do that, eventually ending up with some complex Claybook (https://www.claybookgame.com/ https://www.claybookgame.com/) style engine.
