rain slanted streaks
Wind-slanted rain streaks with depth: near drops are longer, faster, and brighter than far ones.
slant_deg is the only configurable wind in the particle family.
Properties
| key | type | default | meaning |
|---|---|---|---|
count | integer | `90` | Number of drops. Rain is a volume, so the default is the densest in the family. |
color | [r,g,b,a] | `[0.72, 0.80, 0.95, 0.65]` | Drop color (cool translucent blue-grey); alpha sets the brightness of the nearest drops. |
length_px | float | `36.0` | Streak length in logical px for the nearest drops; farther drops shrink automatically. |
slant_deg | float | `10.0` | Shared wind angle in degrees from vertical; positive leans the fall rightward. All drops share it, so the rain falls as a coherent sheet. |
every key is optional; omit it and the default applies. misspelled keys are silently ignored, so if a setting seems to do nothing, check the spelling against this table. colors are 0.0–1.0 float arrays.
