UE1 - UT RMFXMusicTrigger (Enhanced MusicEvent trigger)

[RoninMastaFX]

Heya! As part of the UT: Forgotten Classics BP, for one level, I need to code an advanced MusicEvent trigger, to allow multiple songs to be played w/o the use of a trigger needed to be activated. It plays the songs in order that they are listed (Song0 to Song9, 10 song slots), and the option to loop back to the first song once the looping is complete.

This is my code so far (it's based from the MusicEvent trigger, since extending it would cause some issues in the long run ^^ ):

}

I have left the "bUseMultipleSongs" & "bLoopMultipleSongs" booleans blank for now, as I don't want to code up something that proves itself useless. ^^ =/ Therefore, I politely ask someone to help me fill in those 2 blanks, and spot any typos or errors if need be! I am only a novice coder, so I still have a *LOT* to learn, but I am getting there slowly.

Any help will be *MUCH* appreciated!

Take care for now, ^^

Ok.. I'll have a crack at bLoopMultipleSongs. Since I only code weapons, I can try some pseudo code..

// Loop back to Song0
if( bLoopMultipleSongs )
{
If Song9 is currently playing, and it has finished
Change the song to Song0
If Song9 isn't playing
Then do nothing
}

That's my idea. Might be a much better solution though. (One that actually involves code)
Might not even need the last two lines either...

Code has been perfected by BlackCheetah! Many thanks to him!

Do whatever with this code...I don't really care (although credits to me and BlackCheetah would be nice )

Why did you ignore the SongSection option? And why is this thread closed?

In the for loop you're looking for 10 slots but in the variables you only have 9 slots. You need to make the struct and array 10 slots.

// Variables
var config Struct MusicSong
{
	var() string           SongName;
	var() float            SongDuration;
} SongInfo[10];

var() Music Song[10];
