[1.9.4] Entity Rendering

[DARKHAWX]

So I recently decided I would finally create an entity. I had almost finished everything including the render but as I spawn it in game it doesn't seem to render right...

 

Its probably got to do with the fact that I'm using the old RenderingRegistry#registerEntityRenderingHandler() method that is deprecated... The entity is supposed to just be effectively a floating block...

 

Here are the relevant files:

I don't really know what it is wrong, so if possible could someone help me.

If you need any more code, let me know.

Well I get that, but I don't know how not to use the deprecated method... I can't seem to find a tutorial or example that works...

Here's how:

RenderingRegistry.registerEntityRenderingHandler(EntityGreenGoblinGlider.class, new IRenderFactory<EntityGreenGoblinGlider>()
{
    @Override
    public Render<? super EntityGreenGoblinGlider> createRenderFor(RenderManager manager)
    {
        return new RenderGreenGoblinGlider(manager);
    }
});

This is the src to my mod, which only adds a tab and some throwable entities that are in that tab.

 

It shows how to do the entity/item thing, along with registering and rendering and all that nice stuff.

Just vomiting copy-pasta code into your post is not encouraged as a form of answering in this forum, thank you.

 

Oh sorry! I will keep that in mind in future posts
