Is possible to have custom events? I did implement one, but it doesn't seem to be working.

 

event class: http://paste.minecraftforge.net/view/1d1907f2

event triggered: http://paste.minecraftforge.net/view/271a63a0

event handler: http://paste.minecraftforge.net/view/1036b904

handler is register in @init method:

MinecraftForge.EVENT_BUS.register(new PowerEventHandler());

 

It crashes on getting parameter-less constructor (tried even adding one, but then my event rewritten ALL other events...)

            Constructor<?> ctr = eventType.getConstructor();

problem solved. forge does some changes to all events on start using ASM library. the event is in my coremod and namespace was marked with TransformerExclusions so my event didn't get the needed tweaking after start.
