Hi

 

I'm trying to execute some code when a gui chest is open.

To do that I do :

public void playerInteractEvent(PlayerInteractEvent event) {
	if(event.action == PlayerInteractEvent.Action.RIGHT_CLICK_BLOCK) {
		//Player right click on a block
		if(!event.entityPlayer.isSneaking()) {
			//Player is not sneaking
			TileEntity t = event.world.getTileEntity(event.x, event.y, event.z);
			if(t instanceof TileEntityChest) {
				FMLClientHandler.instance().displayGuiScreen(event.entityPlayer, new GuiChest(event.entityPlayer.inventory, (IInventory) t));
				event.setCanceled(true);
				// DO SOMETHING
			}
		}
	}
}

 

It's work, chest gui appears.

But when I select an Item, I have a IndexOfBoundException.

I suppose I don't give the good IIventory to this function but where can I find the good IIventory ?

 

Thanks a lot

You cancelled the event so the chest container isn't open on server side.

You'd need to use a IGuiHandler or GuiOpenEvent instead.

Thanks for your reply, I didn't know the GuiOpenEvent it's very usefull

 

I have an other problem, my button doesn't' appear now

 

This is my code, it's short :

 

@SubscribeEvent
public void onGuiOpen(net.minecraftforge.client.event.GuiOpenEvent event) {
	System.out.println("A gui is open !");
	if(event.gui instanceof GuiContainer) {
		System.out.println("This is a GuiContainer");
		handleGuiContainerLayout((GuiContainer) event.gui);
	}
}

private void handleGuiContainerLayout(GuiContainer gui) {
	GuiSettlementsButton settlementButton = new GuiSettlementsButton(gui);
	List<Object> buttonList = GuiReflect.getInstance().getButtonList(gui);
	if(buttonList != null) {
		System.out.println("We will add our button !");

		buttonList.add(settlementButton);

		System.out.println(buttonList);
	}
}

 

 

This is the button code :

 

public class GuiSettlementsButton extends GuiButtonExt {

public GuiSettlementsButton(GuiContainer gui) {
	super(-1, GuiReflect.getInstance().getGuiLeft(gui), GuiReflect.getInstance().getGuiTop(gui)+gui.height+1,150,20, StatCollector.translateToLocal("tile.SettlementsGuiButton.name"));
}

@Override
public String toString() {
	return "GuiSettlementsButton :\n"
			+ "\tx : "+xPosition+"\n"
			+ "\ty : "+yPosition+"\n"
			+ "\twidth : "+width+"\n"
			+ "\theight : "+height+"\n"
			+ "\ttext : "+this.displayString;
}
}

 

I try with GuiButton instead of GuiButtonExt but, it's the same

 

And this is my log when I open a chest:

A gui is open !
This is a GuiContainer
We will add our button !
[GuiSettlementsButton :
x : 0
y : 1
width : 150
height : 20
text : Settlements]

 

I don't understand why this is write 2 times and why my button is not visible.

 

Could you help me ?

 

Thanks

 

EDIT : It's work fine now, I just don't understand what mean height, I think this was ySize.

So problem resolved
