[1.5.2]A mod tried to open a gui on the server without being a network mod

new TileEntityCharacter()

 

...Really.  A new tile entity.  No no no no.

 

You have a tile entity somewhere that is involved.  Generally when the player right clicks it is when you open a gui for it.  That method is inside a tile entity and has reference to itself.

 

Unfortunately with the code you have supplied I'm not sure you even HAVE a tile entity anywhere.  So I don't know why you're trying to reference it at all.

 

I think I figured out, but it crashes with a NPE:

 

private void openCharacterGui(Packet250CustomPayload packet,
		EntityPlayer player) {
	DataInputStream inputStream = new DataInputStream(
			new ByteArrayInputStream(packet.data));
	TileEntity tileEntity = player.worldObj.getBlockTileEntity((int)player.posX, (int)player.posY, (int)player.posZ);
			player.openGui(
			ExoWorld_Client.instance, GuiRegistry.guiCharacter,
			player.worldObj, tileEntity.xCoord, tileEntity.yCoord, tileEntity.zCoord); //<------------------------ Here
	System.out.println("Gui Aperto!");
}

 

I think because xCoord, yCoord and zCoord are empty

I am not going to repeat myself, so i'll quote Draco:

floor, ceiling, round...none of those are going to locate a tile entity that encases the player's feet.

You should get the location of the tile entity from itself and pass the xyz in the packet.

And add that question: what is TileEntityCharacter supposed to do, and why do you insist on locating it inside the player ?

No:

 

TileEntity tileEntity = player.worldObj.getBlockTileEntity((int)player.posX, (int)player.posY, (int)player.posZ);

 

Your tileEntity is null.  Because there's no tile entity AT that location.  This has been your problem from the beginning.  There is not, will not, never has been a tile entity at the player's feet because THERE IS NO ENTITY THERE so stop trying to reference it.

 

You get a crash on that line because null does not have an xCoord value.

No:

 

TileEntity tileEntity = player.worldObj.getBlockTileEntity((int)player.posX, (int)player.posY, (int)player.posZ);

I think I need to change everything, because my intention was a new inventory gui (not like the standard one, but like the inventory character of every RPG) here's the screen:

I need to delete tileentity, make a NEW container and a NEW gui (I delete the old ones) and then open it with "Minecraft.getMinecraft().displayGuiScreen();" right?

[Draco18s]

Yes.

 

Delete the tile entity.

 

You're not using a tile entity.  At all.  Anywhere.  Get rid of it.  Player inventory screen is not a tile entity.

You can keep your GuiCharacter and ContainerCharacter. Just delete anything related to TileEntityCharacter.

Finally, it works! It opens the gui, but it isn't resized as well. I'm fixing this problem right now, if you can help me then do it
