Simple Powder Sim

A simple powder sim program, featuring four different materials, each with their own behaviors.

Particle types

• Sand: Tries to move down if possible, then tries to move down-left if possible, then tries to move down-right if possible. This causes it to form piles.
• Stone: Tries to move down if possible. This causes it to form pillars.
• Water: Tries to move to the closest, lowest tile if possible. This causes it to try to fill an area while remaining as level as possible.
• Bedrock: Does not move. This allows it to be used to make floating platforms that other particles can land on.

Controls

• Left Click: Places the selected particle type at the cursor's position.
• Right Click:  Hold down to rapidly place the selected particle type at the cursor's position.
• G: Press to delete the particle at the cursor's current position.
• Q: Press to bring up a radial menu to change particle types. Left click while hovering over a particle type to change to that type. Press **Escape** to close the menu.
