Hello everybody ! I begin in modding with forge and i want to do some custome gui. And i made it works ! My custom gui is opened with the J key and all slots are well placed (There are 40 slots in the container plus all the slots of the player inventory. But when i click on a slot with a number greater than 44, my game crashes. I use a custom container and a custom tileEntity and in my custom container, there is a clickSlot method overriden(ftm it returns null). But when it crashes, it says there is an error on this method...

Here is the error report :

Did you override slotClick method?

It seems that you had mistaken with the function "clickSlot" ...

You should add @Override annotation when you overrides a function.

Yep i said the wrong methode in my first message but i overrided the good one ^^ here is my container code :

package shuyin.test.fy;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.InventoryPlayer;
import net.minecraft.inventory.Container;
import net.minecraft.inventory.IInventory;
import net.minecraft.inventory.Slot;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;

public class DeckContainer extends Container{
protected DeckTile tile_entity;
public DeckContainer(InventoryPlayer player_inventory, DeckTile tile){
this.tile_entity = tile;
int k = 0;
for(int j = 0 ; j < 5 ; j++){
	for(int i = 0 ; i < 8 ; i++){
		addSlotToContainer(new CardSlot(tile_entity, k, 17 + i * 18, 11 + j*18));
		k++;
	}
}
bindPlayerInventory(player_inventory);
System.out.println(this.inventorySlots.size());
}

protected void bindPlayerInventory(InventoryPlayer player_inventory){

	for(int i = 0; i < 3; i++){
		for(int j = 0; j < 9; j++){
			addSlotToContainer(new Slot(player_inventory, j + i * 9 + 9, 8 + j * 18, 140 + i * 18));
		}
	}

	for(int i = 0; i < 9; i++){
		addSlotToContainer(new Slot(player_inventory, i, 8 + i * 18, 198));
	}
}

@Override
public ItemStack slotClick(int par1, int par2, int par3, EntityPlayer par4EntityPlayer)
{
	System.out.println( par1+" " + par2 + " " + par3);
	System.out.println(this.inventorySlots.size());

	return null;
}
@Override
public ItemStack transferStackInSlot(EntityPlayer player, int slot){
	ItemStack stack = null;
	Slot slot_object = (Slot) inventorySlots.get(slot);

	if(slot_object != null && slot_object.getHasStack()){
		ItemStack stack_in_slot = slot_object.getStack();
		stack = stack_in_slot.copy();

		if(slot == 0){
			if(!mergeItemStack(stack_in_slot, 1, inventorySlots.size(), true)){
				return null;
			}
		} else if(!mergeItemStack(stack_in_slot, 0, 1, false)){
			return null;
		}

	if(stack_in_slot.stackSize == 0){
		slot_object.putStack(null);
	} 
	else{
		slot_object.onSlotChanged();
	}
}

return stack;
}

@Override
public boolean canInteractWith(EntityPlayer player) {
	return tile_entity.isUseableByPlayer(player);
}

}

It's very strange because i wrote some debug messages that appears in my console when i play there is nothing weird...

I think it is related with your GuiHandler. can you post the code?

Here is my GuiHandler code :

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;
import cpw.mods.fml.client.FMLClientHandler;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.InputEvent;
import cpw.mods.fml.common.network.IGuiHandler;

public class CommonProxy implements IGuiHandler{


@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	if ( ID == DeckGui.GUI_ID){

            return new DeckContainer(player.inventory, Main.liste.get(player.getUniqueID()));
	}
	// TODO Auto-generated method stub
	return null;
}

@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	if ( ID == DeckGui.GUI_ID){
            return new DeckGui(player.inventory, Main.liste.get(player.getUniqueID()));
	}
	// TODO Auto-generated method stub
	return null;
}

}

 

The Main.list is a HashMap with UUID keys and DeckTile .

TileEntity is related to a Block in the World. You can't have it in this HashMap from your Main class.

I think your container is not overriden during the crash..

Can you debug with it.?

I'm sorry i don't undestand, what do you mean by "debug with it" ?

Before that: Can you post the code related with Main.list?

here is my keyInputHandler (i use it for open my GUI) :

import net.minecraft.client.Minecraft;
import net.minecraft.client.entity.EntityClientPlayerMP;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.world.World;
import cpw.mods.fml.client.FMLClientHandler;
import cpw.mods.fml.client.registry.ClientRegistry;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.InputEvent;
import cpw.mods.fml.common.network.IGuiHandler;
import cpw.mods.fml.common.network.internal.FMLNetworkHandler;

public class KeyInputHandler extends CommonProxy{

@SubscribeEvent
    public void onKeyInput(InputEvent.KeyInputEvent eventK) {
	EntityPlayer player = FMLClientHandler.instance().getClient().thePlayer;
        if(KeyBindings.deck.isPressed())
        	if(player != null && Main.instance != null && player.worldObj != null){
        		if(!Main.liste.containsKey(player.getUniqueID()))
        			Main.liste.put(player.getUniqueID(), new DeckTile());
        		player.openGui(Main.instance, 30, player.worldObj, (int)Math.floor(player.posX), (int)Math.floor(player.posY), (int)Math.floor(player.posZ));
        	}

    }

@SubscribeEvent
public void onMouseInput(InputEvent.MouseInputEvent eventM){
	EntityPlayer player = FMLClientHandler.instance().getClient().thePlayer;
                //not used ftm

}


}

 

and my main class :

import java.util.HashMap;
import java.util.UUID;

import shuyin.yugioh.fm.items.Carte;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.init.Items;

public class Main
{
public static HashMap<UUID, DeckTile> liste;

public static KeyInputHandler proxy = new KeyInputHandler();
public static CommonProxy gui = new CommonProxy();

public static final String MODID = "yugfm";
public static final String MODNAME = "testModGui";
public static final String VERSION = "0.0.1";
public static Item carte;

@Instance ( MODID )
    public static Main instance;

public static CreativeTabs tabCard = new CreativeTabs("tabName")
{
	public Item getTabIconItem()
	{	
		return Items.arrow;
	}
};


@EventHandler
public void preInit(FMLPreInitializationEvent e)
{

}

@EventHandler
public void init(FMLInitializationEvent e)
{
	instance = this;
	liste = new HashMap<UUID, DeckTile>();
	KeyBindings.init();
	carte = new Carte();

	GameRegistry.registerItem(carte, MODID + ":" + "test");
	GameRegistry.registerTileEntity(DeckTile.class, MODID);

	NetworkRegistry.INSTANCE.registerGuiHandler(this, gui);
	FMLCommonHandler.instance().bus().register(proxy);
}

@EventHandler
public void postInit(FMLPostInitializationEvent e)
{

}
}

 

Up.

 

Any idea ?

TileEntity is related to a Block in the World. You can't have it in this HashMap from your Main class.

World#getTileEntity(int, int, int)

 

And opening your container from client side (key handler) is not going to work. You need to send a packet to the server and open the container on server side.
