Minecraft forge mod: Remove a block and place a new block

[halmi4]

 

I am currently making a minecraft forge mod. Do anyone know how to first remove a block on specific coordinates, and then place a new block on the same place? Like replacing the old block with a new block.

 

I will have it in the middle of this code:

 

if(player.getCurrentEquippedItem() != null)

      {

       

        if(hand.getItem() == Items.dirt)

        {

           

        }

       

      }

the Item.dirt is just a test

 

So if the player hold a specific item(i use dirt at the moment) and right click on the block, something will happend. Btw i have more code over that code that makes that happend when the player right click on the block.

 

I've Googled for it and didn't find anything.

That's not how you compare Item Stacks.

 

You should, in this case, be doing

hand.getItem() == Items.dirt

If the item is custom (yours):

Look at the ItemHoe#onItemUse();

 

You can literally copy that code and change stuff you need.

 

Note: you will use different methods for left or rightclick.

 

If item is vanilla:

1. Subscribe to PlayerInteractEvent, do needed checks (for nulls and item held) and do your stuff.

OR

2. Subscribe to PlayerUseItemEvent and do same as above - note: there are sub-events there.

 

Or find other events, there are probably few more that would allow it.

To actually replace the block use

 

world.setBlock(x, y, z) [1.7.X]

world.setBlock(pos) [1.8] (not sure if that's correct haven't updated to 1.8 yet)

To actually replace the block use

 

world.setBlock(x, y, z) [1.7.X]

world.setBlock(pos) [1.8] (not sure if that's correct haven't updated to 1.8 yet)

 

FYI:

 

In 1.8 you have to do it like this:

 

world.setBlockState(BlockPos, IBlockState);

 

Example:

 

IBlockState dirtBlock = Blocks.dirt.getDefaultState();

world.setBlockState(new BlockPos(x, y, z), dirtBlock);

 

or with metadata

 

IBlockState plankBlock = Blocks.planks.getStateFromMeta(3); //This will be a jungle plank

world.setBlockState(new BlockPos(x, y, z), plankBlock);

 

Hope this helps you when you decide to update to 1.8 .

 

EDIT: Read what diesieben07 said.

@Lewie: Don't use getStateFromMeta, it completely defeats the purpose of block states. The beauty is that with Block states you don't have a random number like 3, you use something like this:

 

IBlockState junglePlanks = Blocks.planks.getDefaultState().withProperty(BlockPlanks.VARIANT, BlockPlanks.EnumType.JUNGLE);

 

Oh wow that's a lot easier, thanks for that .
