Properly block updateTick with server

[SeKtOR]

I need explain how to make updateTick work properly in smp(server). Current bug: when all players left chunk block forget about "updateTick". Off course i found solution is "Packets", but i don't know how(i need example of properly server and client sync).

Current code:

package my_epic_package;

import java.util.Random;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import net.minecraft.world.IBlockAccess;

public class BlockSomething extends Block {
private int index = 0;

    public BlockSomething(int par1, int par2, boolean par3)
    {
        super(par1, par2, Material.rock);
	if(!par3) {
	this.index = 16;
	} else {
	this.index = 0;
	}
    }

    public void onBlockAdded(World par1World, int x, int y, int z) {
par1World.scheduleBlockUpdateFromLoad(x, y, z, blockID, 20);
par1World.scheduleBlockUpdate(x, y, z, blockID, 20);
    }

public void updateTick(World par1World, int x, int y, int z, Random par5Random) {
super.updateTick(par1World, x, y, z, par5Random); // I don't know why...
if(!par1World.isRemote) {
        // My epic code 
}
        }
    
    public int getBlockTextureFromSide(int i) {
    	switch(i)
    	{
        case 0: return 82 - this.index;
        case 1: return 80 - this.index;
        default: return 81 - this.index;
    	}
    }

    public boolean canConnectRedstone(IBlockAccess world, int x, int y, int z, int side) {
        return true;
    }

    public boolean renderAsNormalBlock()
    {
        return false;
    }

public String getTextureFile () {
        return ClientProxy.BLOCK_PNG;
}
}

 

P.S. Sorry for bad english

I'm pretty sure you shouldn't be using

scheduleBlockUpdateFromLoad

. It's not clear from your question, the block is working on a server side? If you're calling

scheduleBlockUpdate

in

updateTick

it should be. You're asking us, how to synchronize inner state of block? Well, without TileEntity the block is synchronized automatically, only data it can hold is one number - metadata (automatically as long as you're changing it with "notify" version of method, e.g.

setBlockMetadataWithNotify

). If you want to have saved more than 4bits then you have to implement TE and possibly synchronize both sides using TE packets. one thead with this topic can be found here - http://www.minecraftforge.net/forum/index.php/topic,6261.msg33322.html#msg33322 .

 

EDIT: the "notify" methods notify neighbours of the block, it should work even without them.

Thanks! I think this working...
