[1.6.4] Display some values of the TileEntity in the GUI

[MagicHaze]

Hey Guys,

 

since a few days i am trying to display some values of my TileEntity in my GUI but i don't get it work. I only get  the new values if i reopen the gui.

 

I tried this in my TileEntity to send the new values to the client but it doesnt work.

public void syncWithGUI(){
	ByteArrayOutputStream bos = new ByteArrayOutputStream(6);
        DataOutputStream outputStream = new DataOutputStream(bos);
        
        try{
        	outputStream.writeInt(displayMessageID);
        	outputStream.writeBoolean(isUnlocked);
        	outputStream.writeInt(xCoord);
        	outputStream.writeInt(yCoord);
        	outputStream.writeInt(zCoord);
        }catch(Exception e){}
        
        Packet250CustomPayload packet = new Packet250CustomPayload();
        //This channel is also registered in my basemodclass
        packet.channel = ModInformation.CHANNEL + "C";
        packet.data = bos.toByteArray();
        packet.length = bos.size();
        
        PacketDispatcher.sendPacketToAllPlayers(packet);
}

 

After every change on the server TileEntity i call all of these methods:

worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);
			worldObj.markBlockForRenderUpdate(xCoord, yCoord, zCoord);
			worldObj.notifyBlockChange(xCoord, yCoord, zCoord, BlockInfo.CODELOCKBLOCK_ID);
			updateEntity();
			syncWithGUI();

 

And here is my packetHandler:

public class PacketHandler implements IPacketHandler {
@Override
public void onPacketData(INetworkManager manager,
		Packet250CustomPayload packet, Player player) {
	if(packet.channel == ModInformation.CHANNEL + "S")
			handleServerPacket(packet,player);
	else if(packet.channel == ModInformation.CHANNEL + "C")
		handleClientPacket(packet, player);
    }
    
private void handleServerPacket(Packet250CustomPayload packet,Player player) {
	DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(packet.data));

	String inputCode;
	byte buttonId;
	int xcoord;
	int ycoord;
	int zcoord;

	Entity playerEntity = (Entity)player;
	TileEntity thisTileEntity;
	TileEntityCodeLock thisTileEntityCodeLock;

	try {
		buttonId = inputStream.readByte();
		inputCode = inputStream.readUTF();
		xcoord = inputStream.readInt();
		ycoord = inputStream.readInt();
		zcoord = inputStream.readInt();

	} 
	catch (Exception e) {
		ChatMessageComponent cMS = new ChatMessageComponent().setColor(EnumChatFormatting.GREEN);
		cMS.addText("Failed to read inputstream!");
		((EntityPlayer)player).sendChatToPlayer(cMS);

		return;
	}
            
	thisTileEntity = playerEntity.worldObj.getBlockTileEntity(xcoord, ycoord, zcoord);
	if (thisTileEntity != null) {
		try{
			thisTileEntityCodeLock = (TileEntityCodeLock) thisTileEntity;

			switch(buttonId){
			case 10:
				if(!thisTileEntityCodeLock.hasCode())
					thisTileEntityCodeLock.setCode(inputCode, (EntityPlayer)player);
				else
					thisTileEntityCodeLock.toogleLock(inputCode, (EntityPlayer)player);
				break;
			case 11:
					thisTileEntityCodeLock.tooglePulseMode(inputCode, (EntityPlayer)player);
				break;
			case 12:
				thisTileEntityCodeLock.setCode(inputCode, (EntityPlayer)player);
				break;
			}						        			
		}
		catch(Exception e){
			ChatMessageComponent cMS = new ChatMessageComponent().setColor(EnumChatFormatting.GREEN);
			cMS.addText("Failed to handle packet!");
			((EntityPlayer)player).sendChatToPlayer(cMS);
		}
	}
}

private void handleClientPacket(Packet250CustomPayload packet, Player player){
	DataInputStream inputStream = new DataInputStream(new ByteArrayInputStream(packet.data));

	int displayMessageID;
	boolean isUnlocked;
	int xCoord;
	int yCoord;
	int zCoord;

	try{
		displayMessageID = inputStream.readInt();
		isUnlocked = inputStream.readBoolean();
		xCoord = inputStream.readInt();
		yCoord = inputStream.readInt();
		zCoord = inputStream.readInt();

		World world = (World) player;
		TileEntityCodeLock thisTileEntityCodeLock = (TileEntityCodeLock)world.getBlockTileEntity(xCoord, yCoord, zCoord);
		thisTileEntityCodeLock.displayMessageID = displayMessageID;
		System.out.println("Angekommen");
	 }catch(Exception e){}

}
}

 

I read tons of tutorials but i dont get it. Can someone help me pls?

 

PS: In the handleClientPacket it fails at the try block, i think the problem is the (World) and the (TileEntityCodeLock) cast?

 

PSS: Short explenation: I send packets by the gui to the server tileentity which does some stuff and should update its fields on the client side that the gui can display the new values.

[GotoLink]

packet.channel == ModInformation.CHANNEL + "S"

This doesn't work because String are immutable, use #equals(obj).

 

worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);
			worldObj.markBlockForRenderUpdate(xCoord, yCoord, zCoord);
			worldObj.notifyBlockChange(xCoord, yCoord, zCoord, BlockInfo.CODELOCKBLOCK_ID);
			updateEntity();
			syncWithGUI();

You are going overboard. Choose one method and stick with it.

Thanks for help, i got i now. I also figured out how to send packets from server to client.

 

But directly got an other problem at the following code.

If i change the meta from my tielentity (or i call any method which would do this) the displayOutputMessage wont get updated (only if the meta wasnt changed).

If i use a field in my tielentity which stores if the block is locked (no redstonesignal) and use this field in my isProvidingStrongPower() method (method of the Block class - if i would call it from my tileentity the strings also wouldnt get updated) to change the meta and also directly provide power the fronticon only changes if my block is connected to a redstonewire or something else with can get a signal.

if(buttonID == 10){
    		if(this.code.equals(code)){			
    			isLocked = isLocked == true ? false : true;
    			this.displayOutputMessage = isLocked == true ? "Signal enabled!" : "Signal disabled!";
    		}
    		else{
    			this.displayOutputMessage = "Wrong Code!";
    		}
    	}
    	else if(buttonID == 11){
    		if(this.code.equals(code)){
    			this.isSignalStatic = this.isSignalStatic == true ? false : true;
    			this.displayOutputMessage = this.isSignalStatic == true ? "Output: Long signal!" : "Output: Short signal!";
    		}
    		else
    			this.displayOutputMessage = "Wrong Code!";	
    	}
    	else if(buttonID == 12){
    		if(this.owner.equals(owner)){
    			this.code = code;
    			this.displayOutputMessage = "Saved new code!";
    		}
    		else if(this.owner == ""){
    			this.code = code;
    			this.owner = owner;
    			this.displayOutputMessage = "Saved new code!";
    		}
    		else{
    			this.displayOutputMessage = "You are not allowed!";
    		}	
    	}
    	
    	if(!isLocked && worldObj.getBlockMetadata(xCoord, yCoord, zCoord) % 2 == 0){
		worldObj.setBlockMetadataWithNotify(xCoord, yCoord, zCoord, worldObj.getBlockMetadata(xCoord, yCoord, zCoord) + 1, 3);
	}
	else if (isLocked && worldObj.getBlockMetadata(xCoord, yCoord, zCoord) % 2 == 1){
		worldObj.setBlockMetadataWithNotify(xCoord, yCoord, zCoord, worldObj.getBlockMetadata(xCoord, yCoord, zCoord) - 1, 3);
	}
    	//worldObj.markBlockForUpdate(xCoord, yCoord, zCoord);
