I think it is impossible as minecraft always generates an infinite map

This is the furthest I'll go private void removeCraftRecipe(ItemStack stack) { Iterator<IRecipe> recipes = CraftingManager.getInstance().getRecipeList().iterator(); while (recipes.hasNext()) { ItemStack output = recipes.next().getRecipeOutput(); if (output.isItemEqual(stack)) { recipes.remove(); } } }

So basically fuck all the code that I've got already and just do that instead of what I've got... No thanks...

OK SENSEI private void removeCraftRecipe(ItemStack stack) { Iterator<IRecipe> recipes = CraftingManager.getInstance().getRecipeList().iterator(); while (recipes.hasNext()) { ItemStack output = recipes.next().getRecipeOutput(); if(output != null && output.getItem() != null) { if(output.isItemEqual(stack)) { recipes.remove(); } } } }

private void removeCraftRecipe(ItemStack stack) { Iterator<IRecipe> recipes = CraftingManager.getInstance().getRecipeList().iterator(); while (recipes.hasNext()) { ItemStack output = ((IRecipe) recipes.next()).getRecipeOutput(); if(output != null && output.getItem() != null) { if(output.isItemEqual(stack)) { recipes.remove(); } } } } Here you go...

Here is my code using an Iterator private void removeCraftRecipe(ItemStack stack) { Iterator recipes = CraftingManager.getInstance().getRecipeList().iterator(); while (recipes.hasNext()) { ItemStack output = ((IRecipe) recipes.next()).getRecipeOutput(); if(output != null && output.getItem() != null) { if(output.isItemEqual(stack)) { recipes.remove(); } } } }

I've now got this @SubscribeEvent public void onBonemeal(BonemealEvent event) { event.setCanceled(true); World world = event.getWorld(); BlockPos pos = event.getPos(); IBlockState state = world.getBlockState(pos); EntityPlayer player = event.getEntityPlayer(); ItemStack stack; if (player.getHeldItemMainhand().getItem() == Items.DYE && player.getHeldItemMainhand().getMetadata() == 15) { stack = player.getHeldItemMainhand(); } else if (player.getHeldItemOffhand().getItem() == Items.DYE && player.getHeldItemOffhand().getMetadata() == 15) { stack = player.getHeldItemOffhand(); } else { stack = ItemStack.EMPTY; } boolean grown = false; IGrowable igrowable; if (!world.isRemote) { while (state.getBlock() instanceof IGrowable && (igrowable = (IGrowable) state.getBlock()).canGrow(world, pos, state, world.isRemote)) { igrowable.grow(world, world.rand, pos, state); state = world.getBlockState(pos); grown = true; } if (grown) { stack.shrink(1); } } } Only thing is I still get the weird invisible tree bug... The grown boolean is to check if it should take away an item..

How can I do it now? Probably just check both hands like I did before, shouldn't I? Also, how can I make sure it is bonemeal and not any other dye?

I can't do player.getActiveHand() because it isn't active anymore I think..

So.. this? @SubscribeEvent public void onBonemeal(BonemealEvent event) { event.setCanceled(true); World world = event.getWorld(); BlockPos pos = event.getPos(); IBlockState state = world.getBlockState(pos); ItemStack stack = event.getEntityPlayer().getHeldItemMainhand(); if (stack.getItem() != Items.DYE) { stack = event.getEntityPlayer().getHeldItemOffhand(); if (stack.getItem() != Items.DYE) { return; } } if (state.getBlock() instanceof IGrowable) { IGrowable igrowable = (IGrowable) state.getBlock(); if (!world.isRemote) { while (igrowable.canGrow(world, pos, state, world.isRemote)) { igrowable.grow(world, world.rand, pos, state); state = world.getBlockState(pos); if (state.getBlock() instanceof IGrowable) { igrowable = (IGrowable) state.getBlock(); } else { stack.shrink(1); } } } } }

Bump

This isn't that hard... You just test for the position of the player and tp him back if he goes further than the border you set

Why do you want a MapGenStructure instead of a WorldGenerator?

Look at the vanilla Fossils for an example

So... What should the method do?

Also, I get this error in the console [14:16:20] [Server thread/ERROR] [FML]: Exception caught during firing event net.minecraftforge.event.entity.player.BonemealEvent@75452f75:

Oh that... Ok.

Where can I find the javadoc? And what should I look for?

@SubscribeEvent public void onCropGrow(BonemealEvent event) { event.setCanceled(true); World world = event.getWorld(); IBlockState state = event.getBlock(); BlockPos pos = event.getPos(); ItemStack stack = event.getEntityPlayer().getActiveItemStack(); if (state.getBlock() instanceof IGrowable) { IGrowable igrowable = (IGrowable) state.getBlock(); if (igrowable.canGrow(world, pos, state, world.isRemote)) { if (!world.isRemote) { while (igrowable.canGrow(world, pos, state, world.isRemote)) { igrowable.grow(world, world.rand, pos, state); state = world.getBlockState(pos); } world.markAndNotifyBlock(pos, world.getChunkFromBlockCoords(pos), state, world.getBlockState(pos), 2); stack.shrink(1); } } } } Nope...

world.markAndNotifyBlock(pos, world.getChunkFromBlockCoords(pos), state, state, 2); This doesn't work

Which one?

Ah thanks it works, only thing is, it doesn't take away an item... And the tree gets well.. buggy... It isn't rendered until you update the blocks (right-click)...

@SubscribeEvent public void onCropGrow(BonemealEvent event) { event.setCanceled(true); World world = event.getWorld(); IBlockState state = event.getBlock(); BlockPos pos = event.getPos(); ItemStack stack = event.getEntityPlayer().getActiveItemStack(); if (state.getBlock() instanceof IGrowable) { IGrowable igrowable = (IGrowable) state.getBlock(); if (igrowable.canGrow(world, pos, state, world.isRemote)) { if (!world.isRemote) { igrowable.grow(world, world.rand, pos, state); while (igrowable.canGrow(world, pos, state, world.isRemote)) { igrowable.grow(world, world.rand, pos, state); igrowable = (IGrowable) world.getBlockState(pos).getBlock(); } stack.shrink(1); } } } } Doesn't work either

Now it 'crashes' the game when I use bonemeal, so when I use it I can't use anything in the game (use hoes on land, open guis from blocks) and then it crashes when I try to go back to the main menu... No crashes in the console

Thanks, it works!
