trigger_counter

Used to combine multiple inputs (buttons, triggers, etc) to one target.

1.Firstly, create a good sized room (300x300x300) and place your info_player_start and a light in there.

2.Next add a brush to the room with the "trigger" texture on it. Apply the trigger_counter entity to it. Give it a

"target" "lights"
"targetname" "multi".

3.Place 3 buttons on a wall, and give each a

"target"   "multi"

4.Add a light entity. Give it a

"targetname"   "lights" (also, for this example, lets make the light start off, so it turns on when all 3 buttons are pressed) Give it a

"spawnflags"   "1"  (for START OFF)

5.Compile your map and check it out in Quake2.
