I can't set Metadata in server in block crops

 

is block

@Override
public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int t, float fx, float fy, float fz)
{
	Random ran = new Random();
	TileEntityCrops ted = (TileEntityCrops) world.getTileEntity(x, y, z);
	int l = world.getBlockMetadata(x, y, z);

	if(ted.username == player.getCommandSenderName() && l == 7){
		world.setBlockMetadataWithNotify(x, y, z, l -7, 2);
		world.setTileEntity(x, y, z, new TileEntityCrops());
		System.out.println(l);
		this.updateTick(world, x, y, z, ran);
		return true;
	}else{
		System.out.println(l);
		return false;
	}
}

 

is tile

public static String username;

public void processActivate(EntityPlayer player, World world) {
	username = player.getCommandSenderName();
	world.setTileEntity(this.xCoord, this.yCoord, this.zCoord, this);
}

1. You should NEVER call World#setTileEntity yourself - this is done automatically by Minecraft when a block with a TE is placed

 

2. Don't compare String with the '==' operator; use #equals instead

ted.username.equals(player.getCommandSenderName())
instead of
ted.username == player.getCommandSenderName()

 

3. If your TE #username field can be NULL, you'll want to either check that first or swap the order in #2

 

4. You probably don't want your TE's #username field to be static - that means every TE will have the same player name, all the time

 

5. Don't create a new Random every time the Block is activated - the World object already has a Random instance, as does Block. Use one of those instead, OR, if you really want a new Random, add it as a class field.

I need save name player and check it for not player other right click it.
