I mean the sounds, not the music. Do you have any idea how to add ogg music then? I guess this guide can help then (scroll down): http://wiki.beyondunreal.com/Legacy:Music

I am trying to make a level for Harry Potter 1 but the whole level is black, even if I have put lights!

I to understand how to build levels, opened in the editor maps from HP3 (thus I renamed a folder with sounds and then the editor opened a card ). Now at me it is a lot of ideas concerning maps HP3 (in respect of construction of maps it to be pleasant to me HP3 more): very much it would be desirable to make level where there will be all three heroes: Harry, Ron and Hermione (at me it has already turned out! And with the help triggers between them it is possible to change ), I will necessarily make for Harry slide on ice and for Ron Carpe Retractum (that is a when he can move). It will be remarkable, if it will be possible to add sounds (and you will find a way them to hear then to enter the name in the editor). By the way, I have already learned to do comments. And still I should learn to do cutscenes to do mini scenes. In general, it is a lot of plans

By the way, and when it will be approximately ready Magic Walls 2?

That sounds nice, cutscenes are very easy to do I think I am ok with this version of magic walls.

The HPMover cause Harry Potter 2 to crash, but the other Mover works ok. Maybe I have set it up wrong.

Hello!
Sorry i have laggy internrt by 2 weeks.
So now.
Music you can play using kwmusictrigger and in "Song" propety allow the music filename without extesion.
"I am trying to make a level for Harry Potter 1 but the whole level is black, even if I have put lights!" --> It's because HP1 using D3D and OpenGL drive so you must to run in this driver wich show your level properly. Solution: Run hp1 game and click clrt+alt+delete then end hp.exe process. After that run game again and select driver(OpenGL or D3D(You must to check what good for you)(for me OpenGL works only)

Now To Ian:
Yes sounds make toy crash but it's already fixed in MW2(I mean program changes directory name automatically). To Walking as three heroes you can use CompanionTrigger class.

HPMover works good in any HP for me. Doesn't make crash. If you have just said me what is in.
And i don't know when i upload MW2.. Maybe next week or tommorow xPP.
