I have a tile entity that holds a EMSLiquidStack (basically a LiquidStack but with my own liquid) and I'm trying to get the block for the tile entity to chat the liquid and the amount of liquid it contains.  The only problem is when I right click on the block it seems to call onBlockActivated() twice.  Any help would be appreciated.

 

Code:

 

 

Block class:

package QuantumMagic.Blocks;

import QuantumMagic.Core.CreativeTabQuantumMagic;
import QuantumMagic.ElectroMagneticSuspension.TileEntityWithEMSTank;
import QuantumMagic.TileEntities.TileEntityEMSPipe;
import QuantumMagic.TileEntities.TileEntityEMSTank;
import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.util.ChatMessageComponent;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;

public class BlockWithEMSTank extends BlockContainer {

Class <? extends TileEntityWithEMSTank> Tile;

public BlockWithEMSTank(int par1, Class <? extends TileEntityWithEMSTank> tile, String s) {
	super(par1, Material.iron);
	Tile = tile;
	setUnlocalizedName(s);
	setCreativeTab(CreativeTabQuantumMagic.tabQuantumMagic);
}

@Override
public TileEntity createNewTileEntity(World world) {
	try {
		return Tile.newInstance();
	} catch (InstantiationException e) {
		e.printStackTrace();
		return null;
	} catch (IllegalAccessException e) {
		e.printStackTrace();
		return null;
	}
}

@Override
public int isProvidingWeakPower(IBlockAccess world, int x, int y, int z, int side)
{		

	TileEntityEMSPipe tile = (TileEntityEMSPipe) world.getBlockTileEntity(x, y, z);

	if(tile == null)
		return 1;


	return tile.getAmount() > 0 ? 15 : 0;
}


public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int par6, float pX, float pY, float pZ)
    {

	TileEntityWithEMSTank tank = (TileEntityWithEMSTank)world.getBlockTileEntity(x, y, z);

	if(tank != null && tank.getLiquidStack() != null && tank.getLiquid() != null)
		player.sendChatToPlayer(ChatMessageComponent.createFromTranslationKey("This EMS tank contains " + tank.getAmount() + "   " units of " + tank.getLiquid().getName()));

	System.out.println("This EMS tank contains " + tank.getAmount() + " units of " + tank.getLiquid().getName());



        return true;
    }

}

That's because it is called once on the client side and again on the server side.

So I need to use world.isRemote, but which side do I want?

You dont want SideOnly, but you want to run the code client side only since you want to print the chat message.

 

if (world.isRemote()) //This is the client
{
//Code Here
}

Okay.  Thank you!
