# KEYS
|
|
- "targetname" : Name

|
|
- "killtarget" : Target to kill when triggered.
|
|
- "rendercolor" : RGB8 Color of the fade effect.
|
|
- "renderamt" : A8 alpha value we'll hit at max.
|
|
- "duration" : Duration of the effect in seconds.
|
|
- "holdtime" : How long we'll hold on the max color/alpha.
|
|
|
|
# SPAWNFLAGS
|
|
- EVF_FADEDROM (1) : Inverts the fading animation.
|
|
- EVF_MODULATE (2) : Modulate tints the image after "rendercolor" instead of obscuring it.
