For example, blue wool. Here is what I'm doing now:

 

                Block blueWool = Block.getBlockFromName("Blue Wool");
                Item blueWoolItem = Item.getItemFromBlock(blueWool);
                ItemStack blueWoolStack = new ItemStack(blueWoolItem);
                		
                RenderHelper.enableGUIStandardItemLighting();
                this.item.renderItemAndEffectIntoGUI(
                		mc.fontRenderer,
                		mc.getTextureManager(),
                		blueWoolStack,
                		var5 + 8, var6 + ;

 

For comparison, this code works fine:

 

                RenderHelper.enableGUIStandardItemLighting();
                this.item.renderItemAndEffectIntoGUI(
                		mc.fontRenderer,
                		mc.getTextureManager(),
                		new ItemStack(Item.getItemById(35)),
                		var5 + 8, var6 + ;

Wool uses metadata: http://minecraft.gamepedia.com/Data_values#Wool.2C_Stained_Clay.2C_Stained_Glass_and_Carpet

 

Provide it to the ItemStack constructor. Also: Don't use Block.getBlockFromName, use the static fields in the Blocks class (not Block, Blocks).

I'm aware that it uses metadata. I still don't know how you specify the metadata.. There is no Blocks.wool.blue or anything convenient.

From what I understand from dieseben07's posts are that you should do:

ItemStack blueWoolStack = new ItemStack(Items.wool, 1, 11);

 

 

First parameter is the Item

Second is the quantity

Third is the metadata (Blue wool uses a metadata of 11)

Thank you.

 

Sorry diesieben07, some of us need to be spoon-fed :\
