Hey guys I need your quick (hopefully) help. You all know that after opening your inventory you can transfer ItemStacks by clicking on them which brings them into "your hand". I want to do the same thing in my custom Gui.

How? Keeping it short,

Me

make sure your GUI extends GuiContainer and make a new class extending Container and give the player.inventory to that container

 

im cleaning up some code then post it for you

 

also check the wiki for "tiny chest" its a very basic and very usefull example

public class Containercustom extends Container {

private IInventory inventorycustom;
private IInventory playerInv;

public Containercustom (IInventory inventorycustom, IInventory playerInventory) {
	this.equip = equip;
	playerInv = playerInventory;
	int j, k;

	for (j = 0; j < 3; ++j)
        {
            for (k = 0; k < 9; ++k)
            {
                this.addSlotToContainer(new Slot(playerInventory, k + j * 9 + 9, 8 + k * 18, 103 + j * 18-20));
            }
        }

        for (j = 0; j < 9; ++j)
        {
            this.addSlotToContainer(new Slot(playerInventory, j, 8 + j * 18, 161-20));
        }

	this.addSlotToContainer(new Slot(equip, 0, 98, 7));
}

@Override
public boolean canInteractWith(EntityPlayer entityplayer) {
	return true;
}

/**
 * Called when a player shift-clicks on a slot. You must override this or
 * you will crash when someone does that.
 */
public ItemStack transferStackInSlot(EntityPlayer par1EntityPlayer, int par2) {
	return null;
}
}

 

public class GuiHandler implements IGuiHandler {

/**
 * @return an instance of a Container class for the server to use
 */
@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world,
		int x, int y, int z) {
	return new ContainerEquipment(EquipmentManager.getEquipOf(player.username), player.inventory);
}

/**
 * @return an instance of a GuiScreen for the client to use and interact with. Depends on the id passed
 */
public Object getClientGuiElement(int ID, EntityPlayer player, World world,
		int x, int y, int z) {
	return new GuiCustom(new ContainerCustom(new BattleEquipment(), player.inventory));
}

}

 

public class GuiCustom extends GuiContainer{

public static final int GUI_ID = -125167;
private float mx, my;
public EquipmentGui(Container par1Container) {
	super(par1Container);
}

    /**
     * Adds the buttons (and other controls) to the screen in question.
     */
    public void initGui()
    {
        super.initGui();
        this.mc.thePlayer.openContainer = this.inventorySlots;
        this.guiLeft = (this.width - this.xSize) / 2;
        this.guiTop = (this.height - this.ySize) / 2;
    }

    /**
     * Draws the screen and all the components in it.
     */
    public void drawScreen(int par1, int par2, float par3)
    {
        super.drawScreen(par1, par2, par3);
        this.mx = (float)par1;
        this.my = (float)par2;
    }
    
    /**
     * Draw the foreground layer for the GuiContainer (everything in front of the items)
     */
    protected void drawGuiContainerForegroundLayer(int par1, int par2) {
    	
    }

@Override
protected void drawGuiContainerBackgroundLayer(float f, int i, int j) {
	GuiInventory.drawPlayerOnGui(this.mc, guiLeft+34, guiTop+75, 30,guiLeft+51-mx, guiTop+25-my);
	Tessellator tess = Tessellator.instance;
	this.mc.renderEngine.bindTexture("path/to/texture");
	tess.startDrawingQuads();
	tess.addVertexWithUV(guiLeft, guiTop, zLevel, 0, 0);
	tess.addVertexWithUV(guiLeft, guiTop+ySize, zLevel, 0, 1);
	tess.addVertexWithUV(guiLeft+xSize, guiTop+ySize, zLevel, 1, 1);
	tess.addVertexWithUV(guiLeft+xSize, guiTop, zLevel, 1, 0);
	tess.draw();
}
}

Thanks for the basics. Appreciate. Now I want to "hand back" the ItemStack when it isn't one which I allow. For example my inventory should ONLY hold sticks. This is what I ment with the players hand in the first place. Whenever you click a slot with an item that is not a stick nothing should happen. Can someone figure it out how to do THAT?

 

Thanks for the fast respond, I like it

hum, do you want the player to be able to place other items in his inventory with the vanilla E menu, because if you want to limit an item placement ONLY in a certain modded gui you can extends Slot and theres a method to prevent such thing  (its called isStackValid or something like that)

I found this method (which is in IInventory, I believe). The problem is that the auto-sorting, placing, etc. algorithms just don't use it ..... which is of course kinda obnoxious. Hm extending Slot... I dunno I thought about overriding the slotClick(int, int, int, EntityPlayer) method from Container but I don't know what all those parameters are. Does anyone know more about the handed vars?

yeah i guess you wouldnt have auto-sorting, but it makes things sooooo much easier

Well... what ever. I now use my own Slots extending Slot (the slot-sensitive version of isItemStackValid() IS called) and have rewritten the transferStackInSlot() method. This thing is on fire now. Thanks for sharing your knowledge with me.
