Custom enchantment behaviour.

[suppergerrie2]

Hey,

 

If I want to create an enchantment that will make the player change dirt to grass when he has it on his shoes, where should I write that behaviour? Right now I check in the LivingUpdateEvent if the entity has the enchantment, but it feels strange to do it there.

Is that the best way or should I do it another way?

 

@Mod.EventBusSubscriber(modid=Reference.MODID)
public class ModEnchantments {

	public static final Enchantment GRASSNESS = new EnchantmentGrassness();

	
	@SubscribeEvent
	public static void registerEnchantments(Register<Enchantment> event) {
		event.getRegistry().registerAll(GRASSNESS);
	}
	
	@SubscribeEvent
	public static void growGrassness(LivingUpdateEvent event) {			
		int level = EnchantmentHelper.getMaxEnchantmentLevel(GRASSNESS, event.getEntityLiving());
		if(level>0) {
			World w = event.getEntity().world;
			if(!w.isRemote) {
				int r = level+1;
				BlockPos pos = event.getEntity().getPosition();
				for(int x = -r; x <= r; x++) {
					for(int z = -r; z <= r; z++) {
						BlockPos blockpos = pos.add(x,-1,z);
						if(blockpos.distanceSq(pos.getX(), pos.getY(), pos.getZ())>r*r) {
							continue;
						}
						
						IBlockState iblockstate = w.getBlockState(blockpos);
						if (iblockstate.getBlock() == Blocks.DIRT && iblockstate.getValue(BlockDirt.VARIANT) == BlockDirt.DirtType.DIRT && w.getLightFromNeighbors(blockpos.up()) >= 4)
                        {
                            w.setBlockState(blockpos, Blocks.GRASS.getDefaultState());
                        }
					}
				}
			}
		}
	}
	
}

I'd get the boots equipment stack directly, rather than asking for the "best version in all of the player's gear"

But that's just me.
