Alright, let's say I have a music file. I have two questions that sorta concern looping and addition.

1- In a map, when you reach specific parts, or go back past these parts, the music..."builds up" or "builds down". EDIT: Before so marker, the music loops at a certain point, after the certain marker, the music begins a new loop.

2- In a boss battle, specific parts will have a set of music looping, then when the boss transforms or reaches different stages of the boss level, the music also changes accordingly.

My question is how I can do this? Do I have to edit the actual music file and cut it into the sections I want to loop and add? Will it be smooth transitions?

~Thanks.

For #1 you can just edit the music into two or 3 differant tracks, depending on how you want it. the first could be with the snares, then the next track would be the same WITH an added instrument, then the next one, etc. You would have to edit your file in Gold Wave or with the music creation software, unless its a midi, you can open it in Finale or Siebillus and change the instrumentation.

#2 can be done within RM

If you need assistance with #1, id be glad to show how. Just LMK. Hope this helps.

Thanks for that pablo, but actually I was referring to help in Game Maker Code or Events on how to do these things.

oops! Sorry I didnt see it was for game maker. My apologies. The point about the music mixing still stands, though.

For both, I say just cut the track into multiple parts like you had said at the end of your post. It's probably the most effective way to do what you want without having to dive into GML's sound functions too much. Speaking of those, they only work for midi and wave files, anything else you're going to need an extension for Game Maker.

Game Maker's weakest area is sound, as far as it being a seamless transition, it's "possible", that's all I'll say.

I did some sound experiments with changing pitch based on various things going on in the game, like it going higher when more things were going on and slowing down and going to a lower pitch when things calmed down. It worked okay, but I really don't know the sound functions too well.

Distorted Travesty handles sound very straight forward and nothing special. The only extra thing I did was allow the player to adjust the volume for sound effects.

Music convert and cut any part of music is possible. For this use internet. You can find here many types of converter and music editor, From this list download any one for free and use it to create the music part. This is very easy way to make music.
