将以下代码加在.SCR中既可得到效果

thread gas

//-----------

gas:

while(1)

{

for (local.i = 1; local.i

{

local.player = $player[local.i]

if (local.player != NIL && local.player.dmteam != "spectator")

{

if(local.player.music_handled != 1)

{

local.player.music_handled = 1

//local.player playsound gasmask1

huddraw_shader 200 "textures/hud/gasmask_overlay"

huddraw_align 200 left top

huddraw_rect 200 0 0 640 480

huddraw_virtualsize 200 1

huddraw_color 200 1 1 1

huddraw_alpha 200 1

}

}

}

waitframe

}

end

这个不好玩，给自己填麻烦，视野缩小
