[1.7.10]Intercepting Events

[BuddingDev]

Is it possible to somehow intercept any event fired from Forge?

Like, when that pig died, I want it to spawn another pig? Or make some explosion? or drop more porkchop?

 

Yeah, I know something is called @SubscribeEvent...

But How exactly to use it?

That's it - create a method 'public void whatever(EventYouWant)' and then register whatever class it's in to the correct bus. It's important that the event is the ONLY argument for the method.

Bro... this is thing whole Forge bases on - tutorials are everywhere, why waste time here

 

There are tons on events - if asking about examples you gave - yes, for all of them.

 

I'll note out what is needed:

1. Create MyEvents.class that will contain methods with annotation @SubscribeEvent

2. Register that classes instance in preInit.

3. There are several events buses - most is done from Forge's, some from FML (mainly ticking/server events), or other.

 

Example of Forge event:

@SubscribeEvent
public void onHarvestDrops(HarvestDropsEvent event)
{
Block block = event.state.getBlock();
if (block == Blocks.iron_ore)
{
	event.drops.clear();
	event.drops.add(Items.apple);
}
}

Registration:

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

For FML it would be:

FMLCommonHandler.instance().bus().register(new MyFMLEvents());

 

And yes, one class can have multiple events.

I have a tutorial on events here: http://jabelarminecraft.blogspot.com/p/minecraft-forge-172-event-handling.html

Any clue where that list of (yeah) events are at?

So I can go there and browse and choose what I want?

In the Forge source. Learn to browse the packages, classes, and code - it is all there.

Read above.

 

But if you need it - there is a list, idk if it's updated to latest version, but it has most (maybe all) of them.
