I'm trying to make your code work embedded in a fake dragon program but it won't parse this line...
int effectId = event.getPacket().getIntegers().read(0);
Specifically the .getIntegers(), has this been deprecated and if so with what? I replaced it with .getIdIntegers with .getID() but that didn't turn the dragon wing noise off. Thanks in advance!
