Probably a beginner question, but:

How do you break a block properly so that it drops its Items as if a player destroyed it?

Can't figure out which code to use.

Search the Block class for methods containing the word "drop". Choose one to override. If unsure, look at a vanilla example such as diamond ore, which drops diamonds rather than itself. See how it does it and then imitate.

this is taken from one of my mods

 

					Block bit = par1World.getBlock(x+xo, y+yo, z+zo);
					int met = par1World.getBlockMetadata(x+xo, y+yo, z+zo);
					if ((bit instanceof BlockLog)||(bit instanceof BlockLeavesBase)){
						bit.harvestBlock(par1World, plr, x+xo, y+yo, z+zo,met);
						par1World.setBlockToAir(x+xo, y+yo, z+zo);
					}

Left-click block with pickaxe until it breaks.

You shouldn't need to dive into the mechanics of breaking the block; the vanilla behavior should get that far as is. As for hitting until it breaks, that just drops the block by default, not some item (e.g. diamond) found within an ore (e.g. diamond ore).

 

Your something-Block subclass needs to override a method pertaining to what it drops when harvested, but I can't recall the exact method name. Search for "drop" and imitate the BlockDiamond class.

The way I've done it is the same as the way BuildCraft has done it.

You first get drops by calling block.getDrops(), then you get drop chance by calling ForgeEventFactory.fireBlockHarvesting() which is the same fired by forge when a block breaks and is being harvested. Then at last you make another empty list and iterate over the drops list and if a random generated number (every time) is less than the chance you add the drop to your other list.

After you get the drops, iterate over them and spawn each by using world.spawnEntityInWorld().

It's not that hard to look into the ore block file...

 

@Override
public Item getItemDropped(int par1, Random par2, int par3) {
	return Items.diamond;
}

It's not that hard to look into the ore block file...

 

@Override
public Item getItemDropped(int par1, Random par2, int par3) {
	return Items.diamond;
}

 

Some blocks have different multiple drops, and some have different dropped metadata, so block.getDrops is better.
