I am doing something wrong here, lore:

Server - an Integrated Server-thread

Client - a Client-thread

Dedic - A Dedicated Server-thread

 

public class GuiHandler implements IGuiHandler
{
@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
{
	switch (ID)
	{
	case 100: return null;
	}
	return null;
}

@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z)
{
	if (world instanceof WorldClient)
	{
		switch (ID)
		{
		case 100: return new GuiIntroduction();
		}
	}
	return null;
}
}

@SubscribeEvent
public void playerLoggedInEvent (PlayerEvent.PlayerLoggedInEvent event)
{
		System.out.println("LOGGED IN");
		PlayerStats ps = ExtendedPlayer.get(event.player).getStats();
		if (ps.getRace() == null || ps.getSubRace() == null || ps.getOrigin() == null)
		{
			System.out.println("SHOULD OPEN");
			event.player.openGui(RoAMain.instance, 100, event.player.worldObj, (int) event.player.posX, (int) event.player.posY, (int) event.player.posZ);
			PacketDispatcher.sendTo(new PacketOpenCloseGui((byte) 1), (EntityPlayerMP) event.player);
		}
}

public class PacketOpenCloseGui implements IMessage
{
byte b = 0;

public PacketOpenCloseGui() {}

public PacketOpenCloseGui(byte b)
{
	System.out.println("SENDING OPEN CLOSE GUI PACKET");
	this.b = b;
}

@Override
public void toBytes(ByteBuf buffer)
{
	buffer.writeByte(this.b);
}

@Override
public void fromBytes(ByteBuf buffer)
{
	this.b = buffer.readByte();
}

public static class PacketOpenCloseGuiHandler extends AbstractClientMessageHandler<PacketOpenCloseGui>
{
	@Override
	public IMessage handleClientMessage(EntityPlayer player, PacketOpenCloseGui message, MessageContext ctx)
	{
		System.out.println("RECEIVED OPEN CLOSE GUI PACKET");
		switch(message.b)
		{
		case 1: player.openGui(RoAMain.instance, 100, player.worldObj, (int) player.posX, (int) player.posY, (int) player.posZ);
		}
		return null;
	}
}
}

 

On Client-Server:

[22:11:37] [server thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.events.FMLEvents:playerLoggedInEvent:28]: LOGGED IN
[22:11:37] [server thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.events.FMLEvents:playerLoggedInEvent:32]: SHOULD OPEN
[22:11:37] [server thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.network.server.PacketOpenCloseGui:<init>:23]: SENDING OPEN CLOSE 
GUI PACKET
[22:19:25] [Client thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.network.server.PacketOpenCloseGui$PacketOpenCloseGuiHandler:handleClientMessage:44]: RECEIVED OPEN CLOSE GUI PACKET

On Client-Dedic:

[22:12:15] [server thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.events.FMLEvents:playerLoggedInEvent:28]: LOGGED IN
[22:12:15] [server thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.events.FMLEvents:playerLoggedInEvent:32]: SHOULD OPEN
[22:12:15] [server thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.network.server.PacketOpenCloseGui:<init>:23]: SENDING OPEN CLOSE GUI PACKET
And client gets:
[22:12:16] [Client thread/INFO] [sTDOUT]: [com.midstcraft.ernio.RoA.common.network.server.PacketOpenCloseGui$PacketOpenCloseGuiHandler:handleClientMessage:44]: RECEIVED OPEN CLOSE GUI PACKET

 

Bam... nothing happens, no matter if its client or server or dedi...

 

Situation 2:

I tries putting:

@Override
	public IMessage handleClientMessage(EntityPlayer player, PacketOpenCloseGui message, MessageContext ctx)
	{
		System.out.println("RECEIVED OPEN CLOSE GUI PACKET");
		switch(message.b)
		{
		case 1: Minecraft.getMinecraft().displayGuiScreen(new GuiIntroduction());
		}
		return null;
	}

 

Then it works on Client-Server, but on Client-Dedic crashes with no GuiScreen found (which is obvious since it doesn't exist).

 

Question:

How do I make code that works for all?

Instead of using event.player.openGui(...) try using FMLNetworkHandler to open the GUI. This is the code I used to open the GUI for my custom furnace.

This is literally same thing? (For convinience tried it, not working)

 

Edit:

case 100: return new GuiIntroduction();

 

Is getting called (on Client ofc).

Well that's what I did:

1. Tried sending with packed with code on clientHandler: Minecraft.getMinecraft().displayGuiScreen(new GuiIntroduction());

2. Worked on Client-Integrated, when i launched dedic, it crashed since GuiScreen doesn't exist there.

3. Started using openGui

4. Was frustrated

<magic happens>

<Ernio realizes he's retarded and writing this topic and Syso in code was a waste of good 30min>

BAM

case 1: player.openGui(RoAMain.instance, 100, player.worldObj, (int) player.posX, (int) player.posY, (int) player.posZ);
		case -1: player.closeScreen(); break;

<Ernio notices he forgot break; after 1st case>

<Facepalms himself for not even providing full code in this thread (i removed case -1 to not make too long code)>

 

DAMN I am...

Thanks
