playing music while reading note?

[The chaser]

Make a callback for the note (in the entity tab, there should be something like CallbackFunc in it). There, put the callback type (preferabily OnPickup) and then add this somewhere in your .hps, but NOT in void OnStart(), OnEnter and OnLeave.

void OnPickup (string &in asEntity, string &in asType)
{
//Your music
}
