Solved Reading MetadataValue

Hello there.
Metadata is registering, but when I check the block metadata, there`s nothing.

Code:

    @EventHandler
    public void placegold(BlockPlaceEvent e) {
        e.getBlock().setMetadata("yes", new FixedMetadataValue(Main.getInstance(), "no")); // "yes" and "no" just for example
    }

 

So you are looking at the block given by PlayerMoveEvent#getTo(). Are you sure that is the block below the player and not the air block the player is occupying?

Also, I believe that Block MetaData is lost when the server reloads.

 

Block below is checked by condition

Code:

e.getTo().getBlock().getRelative(BlockFace.DOWN).getType() == Material.GOLD_BLOCK

I reload the server before place block.

 

So I'm not sure what your question is at this point. You are storing some metadata in the gold block that players will walk on. But you aren't checking if the gold block has the metadata, you are checking if the block ABOVE the gold block has it.
