[RESOLVED][1.8] Data from server to GUI

[tancfire]

Hello everyone,

 

I have a big problem. I try to get data from server, to put it in a text box, in a GUI, on client side.

 

To open the gui on the current player, it's an other player who type a command. I used a packet to do it. This part works fine. BUT, i can't send a data string from server to the GUI.

 

Here my code:

 

The Command:

public class OfferAllianceCommand extends BaseCommand {

	public OfferAllianceCommand() {
		super("offerAlliance", 2);
	}

	@Override
	public String getCommandUsage(ICommandSender sender) {
		return "/offerAlliance <kingdom> <kingdomTarget>";
	}

	@Override
	public int compareTo(Object arg0) {
		return 0;
	}

	@Override
	public boolean canCommandSenderUse(ICommandSender sender) {
		return true;
	}

	@Override
	public List addTabCompletionOptions(ICommandSender sender, String[] args,BlockPos pos) {
		return null;
	}

	@Override
	public boolean isUsernameIndex(String[] args, int index) {
		return false;
	}

	@Override
	public void onExecute(ICommandSender sender, String[] args) {
		String kingdomName = args[0];
		String kingdomTargetName = args[1];

		KingdomAgeSavedData kt = KingdomAgeSavedData.forWorld(sender.getEntityWorld());
		Kingdom kingdom = kt.getKingdomByName(kingdomName);
		Kingdom kingdomTarget = kt.getKingdomByName(kingdomTargetName);
		
		if(isKingdomExist(sender, kingdom, kingdomName) // si le royaume existe
				&& isOwnKingdom(sender, kingdom, sender.getName()) //si le joueur en est le roi
				&& isKingdomExist(sender, kingdomTarget, kingdomTargetName) //si le royaume cible existe
				&& isConnected(sender, kingdom.getOwner())){ //Et le joueur cible est connecté
			
			System.out.println("Joueur qui envoit l'offre:  "+sender.getName());
			
			EntityPlayerMP playerTarget = MinecraftServer.getServer().getConfigurationManager().getPlayerByUsername(kingdomTarget.getOwner());
			
			playerTarget.getEntityData().setString("allianceOffer", kingdomName);
			
			System.out.println("Kingdom of alliance: "+playerTarget.getEntityData().getString("allianceOffer"));
			
			KingdomAgeMod.network.sendTo(new AllianceOfferMessage(), playerTarget);
			//playerTarget.openGui(KingdomAgeMod.instance, GUIs.ALLIANCE_OFFER.ordinal(), sender.getEntityWorld(), playerTarget.getPosition().getX(), playerTarget.getPosition().getY(),playerTarget.getPosition().getZ());
			//FMLNetworkHandler.openGui(playerTarget, KingdomAgeMod.instance, GUIs.ALLIANCE_OFFER.ordinal(), playerTarget.getEntityWorld(), playerTarget.getPosition().getX(), playerTarget.getPosition().getY(),playerTarget.getPosition().getZ());
		}
	}

}

 

The packet:

 

public class AllianceOfferMessage implements IMessage{
	
	/*private int x;
	private int y;
	private int z;*/
	
	public AllianceOfferMessage()
	{
		
	}

	
	/*public AllianceOfferMessage(int x, int y, int z)
	{
		this.x = x;
		this.y = y;
		this.z = z;
	}*/
	
	
	@Override
	public void fromBytes(ByteBuf buf) {
		/*x = ByteBufUtils.readVarInt(buf, 5);
		y = ByteBufUtils.readVarInt(buf, 5);
		z = ByteBufUtils.readVarInt(buf, 5);*/
	}

	@Override
	public void toBytes(ByteBuf buf) {
		/*ByteBufUtils.writeVarInt(buf, x, 5);
		ByteBufUtils.writeVarInt(buf, y, 5);
		ByteBufUtils.writeVarInt(buf, z, 5);*/
	}
	
	
public static class Handler implements IMessageHandler<AllianceOfferMessage, IMessage> {
        
        @Override
        public IMessage onMessage(AllianceOfferMessage message, MessageContext ctx) {
        	EntityPlayerSP player = Minecraft.getMinecraft().thePlayer;
        	
        	System.out.println("Joueur qui reçoit l'offre:  "+player.getName());
        	
        	player.openGui(KingdomAgeMod.instance, GUIs.ALLIANCE_OFFER.ordinal(), player.getEntityWorld(), player.getPosition().getX(), player.getPosition().getY(),player.getPosition().getZ());
        	
        	
        	return null;
        }
}
}

 

The GUI:

 

public class GuiAllianceOffer extends GuiScreen{
	
    private int x, y, z;
    private EntityPlayer player;
    private World world;
    private int xSize, ySize;
    
    private GuiButton boutonAccept;
    private GuiButton boutonRefuse;
    
    private String kingdomName;
    
    private ResourceLocation backgroundimage = new ResourceLocation(KingdomAgeMod.MODID.toLowerCase() + ":" + "textures/client/gui/guikingdomerrename.png");

	public GuiAllianceOffer(EntityPlayer player, World world, int x, int y, int z) {
        this.x = x;
        this.y = y;
        this.z = z;
        this.player = player;
        this.world = world;
        xSize = 185;
        ySize = 137;
        
        kingdomName = player.getEntityData().getString("allianceOffer");
	}
	
	@Override
	public void updateScreen()
	{
		super.updateScreen();
	}
	
	@Override
	protected void keyTyped(char typedChar, int keyCode) throws IOException
    {
		super.keyTyped(typedChar, keyCode);
    }
	
	
	@Override
    public void initGui()
    {
        boutonAccept = new GuiButton(1, 0, 0, 50,20,"Accept");
        boutonRefuse = new GuiButton(2,0,0,50,20, "Refuse");
        buttonList.add(boutonAccept);
        buttonList.add(boutonRefuse);
    }
	
	
    @Override
    public void drawScreen(int mouseX, int mouseY, float renderPartialTicks) {
        int x = (this.width - xSize) / 2;
        int y = (this.height - ySize) / 2;
        
        boutonRefuse.xPosition = x+xSize-55;
        boutonRefuse.yPosition = y+ySize-25;
        boutonAccept.xPosition = x+5;
        boutonAccept.yPosition = y+ySize-25;
        
        System.out.println("Kingdom of alliance2: "+kingdomName);
    	
        this.mc.getTextureManager().bindTexture(backgroundimage);
        drawTexturedModalRect(x, y, 0, 0, xSize,  ySize);
        drawCenteredString(this.fontRendererObj, "The kingdom of "+kingdomName, x+(xSize/2), y+5, -1);
        drawCenteredString(this.fontRendererObj, "offer you an alliance", x+(xSize/2), y+20, -1);
        
        boutonAccept.drawButton(mc, mouseX, mouseY);
        boutonRefuse.drawButton(mc, mouseX, mouseY);
    }
    
    
    @Override
    protected void actionPerformed(GuiButton button) throws IOException
    {
    	if(button==this.boutonAccept)
    	{
    		//KingdomAgeMod.network.sendToServer(new RenameKingdomMessage(player.getEntityData().getInteger("id_kingdom"),this.editKingdomName.getText()));
    		this.player.closeScreen(); //On ferme la fenêtre du GUI.
    	} else if (button==this.boutonRefuse)
    	{
    		//KingdomAgeMod.network.sendToServer(new DeleteKingdomMessage(player.getEntityData().getInteger("id_kingdom"),x,y,z));
    		this.player.closeScreen();
    	}
    	
    }
    

        @Override
        public boolean doesGuiPauseGame() {
            return false;
        }

	

}

 

I try to put NBTag to the player on server side, and get it on the client side, but it's not working.

 

I have no idea how to do it, so a little help will be appreciate ^^

 

Also, sorry for my english, it's not my native language.

getEntityData is not synced to the client. Use the packet to send the string.

Ok, but how i "take" the string from the packet, to put it in my GUI ?

[tancfire]

It works !

Thanks you very muck !

 

Now, my code is:

 

My packet:

public class AllianceOfferMessage implements IMessage{
	
	private String kingdomName;
	
	public AllianceOfferMessage()
	{
		
	}

	
	public AllianceOfferMessage(String kingdomName)
	{
		this.kingdomName = kingdomName;
	}
	
	
	@Override
	public void fromBytes(ByteBuf buf) {
		kingdomName = ByteBufUtils.readUTF8String(buf);
		
	}

	@Override
	public void toBytes(ByteBuf buf) {
		ByteBufUtils.writeUTF8String(buf, kingdomName);

	}
	
	
public static class Handler implements IMessageHandler<AllianceOfferMessage, IMessage> {
        
        @Override
        @SideOnly(Side.CLIENT)
        public IMessage onMessage(AllianceOfferMessage message, MessageContext ctx) {
        	EntityPlayerSP player = Minecraft.getMinecraft().thePlayer;
        	
        	Minecraft.getMinecraft().displayGuiScreen(new GuiAllianceOffer(player,player.getEntityWorld(),player.getPosition().getX(),player.getPosition().getY(),player.getPosition().getZ(), message.kingdomName));
        	
        	return null;
        }
}
}

Note: To use "Minecraft::displayGuiScreen", i had to put "@SideOnly(Side.CLIENT)

 

My GUI:

	public GuiAllianceOffer(EntityPlayer player, World world, int x, int y, int z, String kingdomName) {
        this.x = x;
        this.y = y;
        this.z = z;
        this.player = player;
        this.world = world;
        xSize = 185;
        ySize = 137;
        
        this.kingdomName = kingdomName;
	}
	
	@Override
	public void updateScreen()
	{
		super.updateScreen();
	}
	
	@Override
	protected void keyTyped(char typedChar, int keyCode) throws IOException
    {
		super.keyTyped(typedChar, keyCode);
    }
	
	
	@Override
    public void initGui()
    {
        boutonAccept = new GuiButton(1, 0, 0, 50,20,"Accept");
        boutonRefuse = new GuiButton(2,0,0,50,20, "Refuse");
        buttonList.add(boutonAccept);
        buttonList.add(boutonRefuse);
    }
	
	
    @Override
    public void drawScreen(int mouseX, int mouseY, float renderPartialTicks) {
        int x = (this.width - xSize) / 2;
        int y = (this.height - ySize) / 2;
        
        boutonRefuse.xPosition = x+xSize-55;
        boutonRefuse.yPosition = y+ySize-25;
        boutonAccept.xPosition = x+5;
        boutonAccept.yPosition = y+ySize-25;
    	
        this.mc.getTextureManager().bindTexture(backgroundimage);
        drawTexturedModalRect(x, y, 0, 0, xSize,  ySize);
        drawCenteredString(this.fontRendererObj, "The kingdom of "+kingdomName, x+(xSize/2), y+5, -1);
        drawCenteredString(this.fontRendererObj, "offer you an alliance", x+(xSize/2), y+20, -1);
        
        boutonAccept.drawButton(mc, mouseX, mouseY);
        boutonRefuse.drawButton(mc, mouseX, mouseY);
    }
    
    
    @Override
    protected void actionPerformed(GuiButton button) throws IOException
    {
    	if(button==this.boutonAccept)
    	{
    		//KingdomAgeMod.network.sendToServer(new RenameKingdomMessage(player.getEntityData().getInteger("id_kingdom"),this.editKingdomName.getText()));
    		this.player.closeScreen(); //On ferme la fenêtre du GUI.
    	} else if (button==this.boutonRefuse)
    	{
    		//KingdomAgeMod.network.sendToServer(new DeleteKingdomMessage(player.getEntityData().getInteger("id_kingdom"),x,y,z));
    		this.player.closeScreen();
    	}
    	
    }
    

        @Override
        public boolean doesGuiPauseGame() {
            return false;
        }

	

}

Here, I put a new parameter "kingdomName" in the gui's constructor.
