I am trying to set spruce logs to drop a custom item when I harvest them with a modded tool, but since spruce logs come from metadata in the BlockOldLog class, I cannot figure out how to adjust them.  I have looked at the

 

event.state.getBlock().getSubBlocks(itemIn, tab, list)

 

section, but I'm stumped.

 

Here is the code that I used for mining gravel with a modded tool.

 

@SubscribeEvent
public void addBlockDrop(HarvestDropsEvent event) {
	if(event.state.getBlock() == Blocks.gravel) {

		Random rand = new Random();

		ItemStack holding = event.harvester.inventory.getStackInSlot(event.harvester.inventory.currentItem);
		if(holding!=null && holding.getItem() instanceof NGShaleMattock) {

			event.drops.clear();
			event.drops.add(new ItemStack(NGItems.viscinousGel, rand.nextInt(4)));
		}
	}
}

 

Any suggestions?

You need to check that the state's

Block

(

IBlockState#getBlock

) is

Blocks.log

, then use

IBlockState#getValue

to get the value of the

BlockOldLog.VARIANT

property. If it's

BlockPlanks.EnumType.SPRUCE

, the log is a Spruce log.

That did it!  I got all mixed up on which side to put it!

 

Here's my code for anymore interested:

 

	if(event.state.getBlock() == Blocks.log) {
		if (event.state.getValue(BlockOldLog.VARIANT) == BlockPlanks.EnumType.SPRUCE) {

			Random rand = new Random();

			ItemStack holding = event.harvester.inventory.getStackInSlot(event.harvester.inventory.currentItem);
			if(holding!=null && holding.getItem() instanceof NGPitchHarvester) {

				event.drops.clear(); //only if you don't want spruce to drop as well as tree pitch
				event.drops.add(new ItemStack(NGItems.treePitch, rand.nextInt(4)));
			}
		}
	}
