Does anyone know how to trigger different music for multiplayer? IE maybe walking through a trigger when you enter a new room?

Yes you go to the easy entite menu (right click on the grid) and go to 'target' and then 'target_speaker' place it where you want it and there you go!

Target_speaker places a sound, but that's not the problem I have. I'm talking about the background music. I know how to place music using the worldspawn entity, but let me put it this way. There's already music playing, the player walks through a certain area and the music changes. That's what I need to know how to do.

Yeah i know, and i've read somewhere that you can use target_speaker for that.

thanks for the suggestion, I'll see what I can do.

Your welcome, anytime
