Env wind

Class hierarchy
CEnvWind ↳CBaseEntity
effects.cpp

Template:Entity It creates wind throughout an entire map.

Important:This is a preserved entity in .
If the game has round restart mechanics this entity may not behave as expected:

More info

On a new round entities with this classname will intentionally not reset. You can use logic_auto to emulate resetting it. Killing it removes it forever, as it is not respawned on a new round. It cannot be spawned with a point_template. Parenting this with non-preserved entities may have undesirable effects.

Note:Wind direction is determined by env_wind's yaw value.

Note:In most games that have $treeSway, this entity is required in order for the materials to simulate wind blowing on them. $treesway does not require env_wind if $treeswaystatic ( only) is used.

Bug:The wind effect in the client game will not change when a new map is loaded which does not contain an env_wind entity.  [todo tested in ?]

Outputs

Bug:env_wind gusts can seemingly pile up and fire this output multiple times when a player first loads into a multiplayer map.

Workaround:Use AddOutput to add OnGustStart effects when players are already connected

Todo: Needs more testing, only observed in
