Help with Custom IItemRenderer


FunshineX

Recommended Posts

I have a custom IItemRenderer working, and need to add the following functionality:

 

First render the default icon for that item.

Then render the icon of a block based on the damage value of the item

 

So it would render my item's icon, then maybe the icon for dirt on top as an overlay.

 

I think my biggest question is how to bind the correct texture sheet of the overlay'd block so I can pass it to renderItem.renderIcon

 

@Override
public boolean handleRenderType(ItemStack item, ItemRenderType type) {
return item.itemID == Items.arcaneTemplate.itemID;
}

@Override
public boolean shouldUseRenderHelper(ItemRenderType type, ItemStack item, ItemRendererHelper helper) {
return false;
}

@Override
public void renderItem(ItemRenderType type, ItemStack item, Object... data) {

Icon icon = item.getIconIndex();
renderItem.renderIcon(0, 0, icon, 16, 16);

switch(item.getItemDamage()) {
case 1:			
	// render Dirt overlay
	break;

case 2:
	// render Cobble overlay
	break;
}

}

When I do

 

icon = Block.dirt.getIcon(1, 1);

renderItem.renderIcon(0, 0, icon, 16, 16);

 

it appears to be rendering half of the lapis icon.

 

Item icons use a different sprite sheet from block icons.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Hi

 

If your Item's custom renderer uses an icon from the block texture map, make sure that Item.getSpriteNumber() returns 0, otherwise the tessellator will render using the item texture map, i.e. the wrong icons will be used.

Not sure how I can do this - I need to render my item's icon first, then render a block icon over top.

 

I can confirm that yes if I override that method for my item , then the block icons work fine, but my item's icon is then not rendered correctly :)  Catch 22

Hi

 

In that case, check out Item.renderItem, in particular this bit

 

        IItemRenderer customRenderer = MinecraftForgeClient.getItemRenderer(par2ItemStack, type);
        if (customRenderer != null)
        {
            texturemanager.func_110577_a(texturemanager.func_130087_a(par2ItemStack.getItemSpriteNumber()));
            ForgeHooksClient.renderEquippedItem(type, customRenderer, renderBlocksInstance, par1EntityLivingBase, par2ItemStack);
        }

 

(func_110577_a and func_130087_a are hopefully called something meaningful in yours)

 

i.e. perhaps it will be enough to call

            texturemanager.func_110577_a(texturemanager.func_130087_a(0));

and

            texturemanager.func_110577_a(texturemanager.func_130087_a(1));

 

before your two custom renders.
