I'm trying to set the state of a GuiButton (and save it to NBT later), but when it triggers the '<TileEntity>.buttonClicked()'-function, the variable on the TileEntity itself is not saved (I assume it saves it in the 'copied'(?) TileEntity, not the actual one)..

 

Here's my code so far:

In GuiAlertBlock.java:

public void actionPerformed(GuiButton button){

	((TileEntityAlertBlock)world.getTileEntity(this.x, this.y, this.z)).buttonClicked();
	List<Entity> players = world.playerEntities;
	for(Entity e: players){
		EntityPlayer player = (EntityPlayer)e;
		player.addChatMessage(new ChatComponentText(player.getDisplayName()));
	}
}

 

In TileEntityAlertBlock:

public void buttonClicked(){
	if(this.buttonState == this.BUTTON_OFF) this.buttonState = this.BUTTON_ON;
	else if(this.buttonState == this.BUTTON_ON) this.buttonState = this.BUTTON_OFF;
	System.out.println();
}

Guis are ClientOnly. To set values in a tileentty(Both sides)from a Gui, youll need to use packethandling to send the value to the server. Diesieben07 has a nice Tutorial on that.

 

Also for spoilers do [ spoiler ] [/ spoiler ] without the spaces

Actually, I did do something with this block and packethandling before, but at that time, it wasn't necessary. (I tried it many different ways, the only thing which I didn't do was to go back using packethandlers.. )

 

Edit: so yeah, it does work now; thanks

Well, the variable updating part works, but now it looks like it doesn't send that to the client because I either draw a red button when the value is 0, or a green one when it's 1, but in the gui the button is not updated at all.

 

That's the line of code for drawing the button:

this.drawTexturedModalRect(this.xPosition, this.yPosition, 176 + ((TileEntityAlertBlock)world.getTileEntity(this.TEx, this.TEy, this.TEz)).buttonState * 20, k * 20, this.width, this.height);

they need to sync the data back from the server to the client again. Look for the methods getdescription packet and on description packet.

I think these are the methods I searched for, I'll try them in the afternoon. Thank you
