Update 0.4: Things that go BOOM!

Nov 19

Pressure system added to the simulation

Pressure now affects all particles.
Large pressure differences can displace objects, even walls.
This system will be fine-tuned in future updates.

New particles:

Dynamite - explodes after a short delay.
Black Powder - explodes when ignited, with a less powerful blast.
Nitroglycerin - highly unstable unless cooled to a more stable state.
Tetracene - detonates upon exposure to electricity.
Black Hole - consumes anything nearby.

Various performance and stability improvements:

Time rewind is now disabled by default on PCs with 4 GB RAM or less, but can be enabled manually in settings.
Improved memory management reduces slowdowns on older PCs with time rewind enabled.

The plutonium won't melt. :-(

The copper will, the glass will, but the plutonium won't. I wanted to create a nuclear meltdown scenario in which a critical mass of plutonium just keeps getting hotter, and since it's liquid, any plutonium that is destroyed is simply replaced to keep the critical mass burning with radioactive fire until the ambient temperature was so hot not even bricks would be able to hold the liquid. Sadly, the plutonium just won't melt. It's melting point is only 600C officially. I should be able to hold molten pluto...

Update 0.3: Play with time!

Aug 31

This is the first content update for Sand in a Box. We're introducing new ways to control the simulation:

Control the speed of the simulation:

Pause and draw in a world without the pressure of flowing time.
Run the simulation at different speeds: normal, 2x, and as fast as your CPU can handle.

Rewind Time:

Press the rewind button to go back in time!
Experiment freely, now you can undo everything.

Improvements to the simulation:

Plutonium can now melt.
Plutonium can become critical at very high temperatures.
Fixed bug that did not draw some pixels of Plant (and other particles with 'absorb' property)

Please note: The rewind feature significantly reduces performance and requires additional RAM. You can disable it in settings.
