"Predator" filter

[oldyz]

Hello, i want to get this question out of the way....

As many of you may know, one of the best looking "predator" filters ever in a 2D game (well its applied to a  2d sprite)
is the one that DooM uses for its Spectre characters.

problem is, it was patched eventually & for later versions & ports they stopped using it because this effect crashes the game...

for comparison, here is PS1's take on them:

Instead, they went with just a ghostly version of the pinkyes.

Basically, for a while the effect was not used, & was wondering if OpenBor could have a similar problem with it...

:edit, it think there is no videos with the actual effect of the original... i will fire up an old '98 machine to capture some footage...

Hi oldyz,

I use in my Tracker character a stealth mod slightly colored in gree in his defensive special like this:

anim special #DEFENSIVE SPECIAL STEALTH CLOAK
	fastattack 1
	jugglecost 5
	forcedirection 0
	energycost 20 2
	loop	0
	fshadow	0
	weaponframe	10 5
	delay	8
	offset	57 115
	hitflash blood
	hitfx	data/sounds/kof/Cutter.wav
	sound	data/sounds/kof/SpecialAttack7.wav
	frame	data/chars/tracker/dspecial1.gif
	attack1 10 64 100 40 16 1 0 0 20 12
	frame	data/chars/tracker/dspecial2.gif
	attack1 5 44 110 40 16 1 0 0 20 12
	frame	data/chars/tracker/dspecial3.gif
	attack1 12 18 85 43 16 1 0 0 20 12
	frame	data/chars/tracker/dspecial4.gif
	attack1 21 16 76 47 16 1 0 0 20 12
	frame	data/chars/tracker/dspecial5.gif
	attack1 12 18 85 43 16 1 0 0 20 12
	frame	data/chars/tracker/dspecial4.gif
	attack1 0 0 0 0 0 0 0 0 0 0
	frame	data/chars/tracker/dspecial3.gif
	frame	data/chars/tracker/dspecial2.gif
	frame	data/chars/tracker/dspecial6.gif
	delay 12
	frame	data/chars/tracker/dspecial7.gif
       drawmethod alpha 6
       drawmethod channelr 0
       drawmethod channelg 0.25
       drawmethod channelb 0
       gfx shadow 0	
	frame	data/chars/tracker/dspecial7.gif
	frame	data/chars/tracker/dspecial7.gif

So

drawmethod alpha 6

sould be the function that you've searched.
You can test him here to see the effect:
