A_FogSpawn
Decrements the calling actor's special1 field and does nothing if this value is still positive.
A_FogSpawn
(no parameters)
Otherwise, reset this field to the value from the calling actor's args[2] field. This value therefore serves as a frequency control on an inverse scale: the larger the value, the less often will calls to this function spawn anything.
Randomly spawns at the calling actor's position a small, medium or large fog patch.
The patch is given an angle corresponding to the spawner's angle plus a random deviation computed from the spawner's args[1] field: each point of args[1] corresponds to a maximum of about 0.7° of deviation either clockwise or counterclockwise.
In addition, the patch is also given values for its args[] and special2 fields which are meant to influence how the patch moves and how long it lives, see A_FogMove for further information on how fog patches react to these arguments:
| Fog patch | Set value | Note |
|---|---|---|
| args[0] | randomly between 1 and the spawner's args[0]+1 | Controls speed |
| args[3] | spawner's args[3] | Controls lifetime |
| args[4] | 1 | Flags the fog patch as moving |
| special2 | randomly between 0 and 63 | Used for vertical bobbing |
This codepointer is restricted to FogSpawner and derived classes.
