I tried placing a Worldspawn in my map and adding target_play_music.
Key is music,
Value is music/impbasee_action.mp3
I placed all the mp3 files into a music folder under base. If I start Singleplayer, type devmap mymap the map starts but it says that impbasee_action is a not a dynamic file (something like that).
What am I doing wrong?
Try NOT to extract the mp3-files you are to use, just type music/cairn_bay/impbasee_action.mp3, and the game will find it from the asstest0.pk3-file
Good luck! :D
