Thanks guys!
I have another question.
I want to set up a "trap" in the missile silo so that when a player presses a button in a control room, there is a count-down before all the players inside the silo will die (from a massive trigger_hurt). This same concept is used in the official dm_runoff.
My questions are:
1. How do I set up a timer?
2. How do I set up an alarm sound that is audible throughout the entire map?
3. Do I trigger a func_trigger with "On_Use" and output to "Activate" the trigger_hurt?
4. Another button (inside the trigger_hurt area) will turn off the alarm.
Thanks in advance!
