2D Effect Snow Fall

[Brandon502]

Effect that simulates snow/sand falling and melting.

Uses getBitValue and setBitValue from Game of Life to reduce memory usage to 1 bit per led.

Sliders:

• Effect Speed: 0 to 60 updates per second
• Spawn Chance: 0% to ~39% chance
• Despawn Chance: 0% to ~38% chance. 255 = 100% chance
• Blur: Fade previous snow location
• Sway Chance: 0% to 100% chance of swaying while free falling

Check boxes:

• Use Palette: Uses palette instead of default snow colors
• Overlay: Allows background effect to color the snow
• Prevent Overflow: If snow reaches the top the bottom opens and empties current snow

I've optimized this as much as I can, easily hits 60fps on 32x32. Likely can still be improved.

Examples on a 32x32 split into 2 segments using different slider/option configs.

Naming and default values can be changed however you'd like. Started out as snow, but palette colors look really nice. Could likely be modified to have an audio reactive version as well.

Hi @Brandon502, nice effect, thank you 😃

I'm a bit busy right now - just tested your effect quickly on 64x64 and it looks very good.
I can take a closer look at the code in the next weeks.

cheers
