Basically, I was previously using code found in RenderItem to render my Tomahawk as a 3D sprite when thrown. Unfortunately, with the massive rendering updates that function has disappeared, and I've had zero luck navigating the rat's nest of unmapped function names to figure out a replacement. Any suggestions? Here is the 1.7.10 version of the class:

No, that isn't what I want at all (already using it for other items btw), what I want is the extruded sprites you see when you drop an item with fancy graphics on. RenderSnowball just renders the item sprite as always facing the player. As I said I was able to do it in 1.7.10, but in 1.8 all the rendering functions have changed and alot of it is still obfuscated, making finding the replacement ridiculously difficult.

Then submit names for them, they are community supplied.

anyways there is a built in way to load the model from a texture. See how the vanilla game does almost every item.

I would quite happily do so if I had ANY idea what was going on, but I don't, hence why I am asking for help from more experienced and astute programmers than I. The only reason I figured it out the first time was because of the helpfully-named functions which no longer exist.

Look at RenderSnowball, as they've told you. You should be able to COPY that, probably verbatim, into whatever render class you are using.

 

It uses RenderItem#renderItemModel(ItemStack) in combination with GLStateManager. If you find the few obfuscated field / function names confusing, look at the type of the variable or return type of the method, if any (e.g. field_177083_e is of type RenderItem, which makes it pretty obvious what it is).

 

Or, even better, since you are just rendering the item anyway, why not just USE RenderSnowball as your render class? Are you doing anything else in there?

As I said before, I am familiar with RenderSnowball and, in fact, I am using it where appropriate. However, right now that is not what I am looking for. RenderSnowball renders an item as a flat sprite which always faces the player. What I am looking for the replacement for "renderItemIn2D", a method which stretches out a sprite and renders it as a 3D model (why the name says 2D I will never know).

All right, I think I tracked it down, maybe, lots more errors to fix to its hard to tell. Anyway, the code I was previously basing this on was moved to RenderEntityItem. In there I found the function I needed, I'll post again once I can actually test this:

renderItem.func_180454_a(itemStack, renderItem.getItemModelMesher().getItemModel(itemStack));
