doesnt work thats why im asking
Ok, Here it is explained a bit better:
Create an ambient_generic.
On Name, type anything you will remember, For example: awesomesound.
Now go to Sound Name and press Browse...
In this example I used
Scout.NeedDispenser01
Now make a trigger brush where you want it to be able to be played.
(tools/toolstrigger), Press CTRL-T to bind it to an entity.
Select trigger_multiple in the drop-down menu on the top.
Go to outputs, Add... and the following:
My output named: OnStartTouch
Target entitys named: the ambient_generic, I used awesomesound.
Via this output: PlaySound
Works perfectly for me, If you have a problem hearing it, Increase the volume on the ambient_generic.
