Hey,

As the topic says I want to draw an items icon in my gui that it looks just like it actually is an item

How do i do that?

I found drawTexturedModelRectFromIcon

and tried it with:

this.drawTexturedModelRectFromIcon(100, 100, new ItemStack(Items.apple).getIconIndex(), 16, 16);

but that's just painting a big fat "nul"

I guess I'm using that ItemStack thing completly wrong?

You need to bind the itemsheet first. Use this to bind the itemsheet:

TextureManager manager = Minecraft.getMinecraft().renderEngine;
            manager.bindTexture(manager.getResourceLocation(1));
//RENDER ITEMS

me again

Uhm so i want to delete a slot and draw the items texture over it,

I have

	@Override
    public void mouseClicked(int x, int y, int z) {
	super.mouseClicked(x, y, z);		
	if(y - guiTop > 30 && y - guiTop < 55 && x - guiLeft > 92 &&  x - guiLeft < 141) {
		tileEntity.onButtonClick();
	}
}

in my gui

and

	public void onButtonClick() {
	slots[0] = null;
}

in my tileEntity, however the slot actually becomes invisible, but when i ckick it it still seems to contain the ItemStack

I guess thats because the Gui stuff where i call the method is client.

Then how do I solve that problem?

You need to send packets to tell the server a button was clicked, let the server decide if that was possible, and then set it to null.

Is there a good tutorial for packets?

(never worked with that  :

See SimpleNetworkWrapper tutorials in the Tutorials section of this forum's Modder Support

Well, I came up with this:

 

	@EventHandler
public static void preInit(FMLPreInitializationEvent event) {
network = NetworkRegistry.INSTANCE.newSimpleChannel("MyChannel");
        network.registerMessage(ClearSlotMessage.Handler.class, ClearSlotMessage.class, 0, Side.SERVER);

}


public class ClearSlotMessage implements IMessage{

public int x;
public int y;
public int z;
    public ClearSlotMessage(int x, int y, int z) { 
    	this.x = x;
    	this.y = y;
    	this.z = z;
    }
    
@Override
public void fromBytes(ByteBuf buf) {
}

@Override
public void toBytes(ByteBuf buf) {
}

public static class Handler implements IMessageHandler<ClearSlotMessage, IMessage> {
    
    @Override
    public IMessage onMessage(ClearSlotMessage message, MessageContext ctx) {
        TileEntityCutter entity = (TileEntityCutter) ctx.getServerHandler().playerEntity.worldObj.getTileEntity(message.x, message.y, message.z);
        if(entity != null) {
//	        	entity.
        	System.out.print("safasfasfasfasfafasfasfas");
        }
        return null;
    }
}

}


public void onButtonClick() { //the method in my tileEntity
	FM.network.sendToServer(new ClearSlotMessage(xCoord, yCoord, zCoord));
}

 

I'm not sure how I use the methods fromByte and toByte (just make x y z binary?)

And what is the "MyChannel"?

Rest ok?

You can use

buf.writeInt(int)

and

int = buf.readInt()

. For more complex stuff, like strings, you can use the ByteBufUtils class. The

"MyChannel"

is the channel it registers to. If two or more mods use the same channel, you get both messages (I think). You should probably prefix your channel name with your modid.
