|
|
# OVERVIEW
|
|
Creates a series (or just one) spark effect with sound when triggered.
|
|
|
|
# KEYS
|
|
- "targetname" : Name
|
|
- "target" : Target when triggered.
|
|
- "killtarget" : Target to kill when triggered.
|
|
- "angles" : Sets the pitch, yaw and roll angles of the spark.
|
|
- "MaxDelay" : Delay between sparks when start-on (or toggle) is set
|
|
|
|
# INPUTS
|
|
- "StartSpark" : Enables a continous spark emitter.
|
|
- "StopSpark" : Stops the ongoing spark emitter.
|
|
- "ToggleSpark" : Toggles the state of the spark emitter.
|
|
- "SparkOnce" : Creates a single spark effect, once.
|
|
|
|
# SPAWNFLAGS
|
|
- TOGGLE (32) : When triggered, it'll spark continously with "MaxDelay" dictating the interval.
|
|
- START_ON (64) : Start sparking upon spawning, at least waiting til "MaxDelay" seconds has passed.
|
|
- SILENT (256) : Do not play a sound.
|
|
- DIRECTIONAL (512) : Angles are respected to direct the spark.
|
|
|
|
# NOTES
|
|
The spawnflag START_ON (32) automatically enables the TOGGLE (64) flag
|
|
as well.
|
|
|
|
