SOLUTION:

 

Extra class for the color registration event:

public static class RegistryEvents
{
	@SubscribeEvent
	public static void registerBlockColors(final ColorHandlerEvent.Block event)
	{
		BlockColors blockColors = event.getBlockColors().register(MY_BLOCK_COLOR, MY_BLOCK);
	}
}

Then, in the main mod method, register that class to the main event bus:

MinecraftForge.EVENT_BUS.register(RegistryEvents.class);

 

PROBLEM:

I'm trying to create a block like grass that changes its color depending on the biome it's in.

I know that I'm supposed to create an IBlockColor, then call 

Minecraft.getInstance().getBlockColors().register(IBlockColor, Block);

However, everywhere that I've tried this, getBlockColors() returns null. 

I've tried creating an event "registerBlockColors" within my RegistryEvents class, but it never gets fired.

@Mod.EventBusSubscriber(bus=Mod.EventBusSubscriber.Bus.MOD)
public static class RegistryEvents {
	@SubscribeEvent
	public static void registerBlockColors(final ColorHandlerEvent.Block event){ //this event is never fired
		Minecraft.getInstance().getBlockColors().register(MY_BLOCK_COLOR, MY_BLOCK);
		//EDIT: This doesn't work either because the surrounding function is never called.
		event.getBlockColors().register(MY_BLOCK_COLOR, MY_BLOCK);
	}
	//other SubscribeEvents are in here
}

What am I doing wrong? I've tried adding the BlockColors via Minecraft.getInstance()... in an onBlockActivated function just to see if my colors work and they do. But this is very obviously the wrong place to register them.

Oh, if only there was a method in the event that to access the BlockColors instance like in all the other registry events...

Oh wait. There is.

Yeah, you mean this, right?

@SubscribeEvent
	public static void registerBlockColors(final ColorHandlerEvent.Block event){
		event.getBlockColors().register(MY_BLOCK_COLOR, MY_BLOCK);
	}

 

This doesn't work either. The function is never called.

ColorHandlerEvent is fired on the main event bus (MinecraftForge.EVENT_BUS). You registered your event handler to the mod event bus.

 

That was it. Thank you so much!

 

For me it says "Type mismatch: cannot convert from void to BlockColors"

        @SubscribeEvent
        public static void registerBlockColors(final ColorHandlerEvent.Block event)
        {
            BlockColors blockColors = event.getBlockColors().register(blockColor, AngryBirdsBlocks.balloon_block,
                                                                                  AngryBirdsBlocks.slingshot_block,
                                                                                  AngryBirdsBlocks.slingshot2_block);
        }

Is there any change for using it in 1.14.3?

 

I noticed, if i delete the part before the "=" i get no more red underlines.

Is this the right way to make it work in 1.14.3

As a note to those trying to use IBlockColor in 1.15, ColorHandlerEvent is now on the Mod Event Bus (Mod.EventBusSubscriber.Bus.MOD).
