And how to add background music :p

Thanks a bunch guys

For music, open the entity window with nothing selected, click on Worldspawn, and enter the key "music" and value "\music\musicfile.mp3"

I could tell you how to make such a door in JO, but I'm not sure how the entities have changed in JA. Try this: make a func_door, and in the entity properties click the "Up" button (to make it open upwards). Now, where you want your button to be, create a trigger_multiple, target it at the door, and check it's use_button and facing spawnflags. You can also use a func_button, if they exist in JA.
