220:Sector_SetCurrent(tag, strength, angle, flags)
Static special that sets a current on tagged sector(s). This is similar to Sector_SetWind, but a current only affects things which touch the ground or are submerged in deep water (as when generated by Transfer_Heights). This is most likely useful for moving water currents, as an alternative to Scroll_Floor.
The tagged sectors must have the wind generalized special field set. Under UDMF, it's 4096. Under Boom it's 512.
You can use floor texture/type changing linedef specials to turn on or off the wind effect, similar to how you do it to affect damaging floors.
- tag: tag of affected sector(s).
- strength: current's strength. Ignored if flags has bit 1.
- angle: current's direction as a byte angle. Ignored if flags has bit 1.
- flags: optional modifier which can be a sum of any of the following values:
