[1.12] how to remove vanilla blocks from registry

Recommended Posts

i am creating a mod to generate all the ores... so i need to change the behavior of the vanilla ones or replace these with my own ones...
for example the ore should drop cobble and nuggets, thats not the problem, the prob is, i cant prevent the ores  of gold and iron to drop (this) (thats should only done with silktouch)... how can i override the setItemDropped method in Block.class or replace Item.getItemFromBlock(this) with Item.getItemFromBlock(Blocks.COBBLESTONE) without changing the original class?
if this isnt possible, how can i replace the vanilla ores with custom ores, at the moment i am searching for a way to remove vanilla ores from the block registry... but all i find is outdated... thanks for any help

Removing blocks from the registry isn't possible. It is possible to override registry entries with your own, but that should be avoided where possible because it can cause compatibility issues if multiple mods try to override the same entry.

 

Instead, you should subscribe to HarvestDropsEvent and add items to/remove items from the drops list as needed. 

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

ok, thanks, I thought the method getItemDropped() in Block.class is not affected by HarvestDropsEvent

Quote

if (event.getState() == Blocks.GOLD_ORE.getDefaultState())
{
    event.getDrops().clear();
    event.getDrops().add(new ItemStack(Items.GOLD_NUGGET, amount_nuggets));
}

works fine...

i am sure... ok i am using

Quote

if (event.getState() == Blocks.GOLD_ORE.getDefaultState())
{
    event.getDrops().clear();
    if (event.isSilkTouching()) event.getDrops().add(new ItemStack(Item.getItemFromBlock(Blocks.GOLD_ORE), 1));
    else
    {
        event.getDrops().add(new ItemStack(Item.getItemFromBlock(Blocks.COBBLESTONE), 1));
        event.getDrops().add(new ItemStack(Items.GOLD_NUGGET, amount_nuggets));
    }
}

but it does exactly what it is supposed to do for this block... or what do you mean?

What is going wrong exactly? You should check that your code is actually executing by either setting a breakpoint and running in debug mode or putting a console print statement inside the if statement. 

 

Assuming that it does run, then it should work. If you look at the call hierarchy for the HarvestDropsEvent, it is called by the fireHarvestDrops() which is called either by harvest methods or the drop with chance methods. The harvest methods will either do some silk touch drops or will call the drop with chance methods. In all cases, the actual item entities creates are directly from the drops list.
