Then when the 40 second to open the doors and the red rotating light will only move when the doors are opening.

Plzz help me

I think i tried this awhile back as well. I dont think there actually is a way to create text that just a few people (area-wise) see. From what i remember at least.

Forget trigger_presense. Just use a regular trigger, same deal. Or even a Logic_auto (or whatever its called), which will be triggered automatically after X seconds after the game starts.

Whether or not you can write text should be irrelevant imo; if you have a decent microphone, just make some audio clips. If you spend a few hours checking out tutorials, you can download a free audio editor, clean them up slightly, and compress them. Add them in with your map (so learn how to create a .res, its REALLY easy, just look at the other .res files to understand), and voila!

can mp3_audio or some other audio enity's is there a why to make them sound in x seconds

trigger_relay named gamestartedstatus with a delay of whatever you want, targeting the target_mp3audio might do the trick.

gamestartedstatus is triggered when a round starts, so any entity with that name will be triggered on roundstart. if this is for a oneshot sound, you can leave it like this. Otherwise you have to trigger the trigger_mp3audio to OFF on round end or it would be triggered to OFF on the next round start.

siege maps use most of the time trigger_random
