Random question. I can't see to get filled Flower Pots to work in structure gen code I'm updating from 1.7.10 to 1.10. Other blocks that have meta data have no issues (e.g., Beds, Chests). But for some reason Pots always come up empty, no matter what I set the meta to.

 

this.setBlock(world, i + 3, j + 6, k + 2, Blocks.FLOWER_POT, 11);

 

public void setBlock(World world, int x, int y, int z, Block block, int metadata)
{
world.setBlockState(new BlockPos(x, y, z), (IBlockState) block.getStateFromMeta(metadata));
}

 

My guess is that it has something to do with 'CONTENTS' but my trail has run cold at this point.

The

BlockFlowerPot.CONTENTS

property isn't stored in the metadata, it's set by

BlockFlowerPot#getActualState

from the values stored in

TileEntityFlowerPot

.

 

After setting the block to

Blocks.FLOWER_POT

, you need to get the

TileEntity

from the

World

and call

TileEntityFlowerPot#setFlowerPotData

to set the contents.

 

Side note: Metadata should be considered an implementation detail, you shouldn't be calling

Block#getStateFromMeta

yourself. Instead, call

Block#getDefaultState

to get the default

IBlockState

and call

IBlockState#withProperty

to get an

IBlockState

with the appropriate property values.

Thanks once again, Choonster. So, it acts like a Chest now, basically. Thanks for the tip on metadata. I see it is deprecated anyway, so I will update.

 

Edit: Yep, works now. That was quite easy. Was staring at the BlockFlowerPot class but completely missed the TileEntity.

Has been for a while.  The only time it used metadata was when it was first added, until Mojang realized there were more than 15 plants and stored the extra in a TE, IIRC.
