How can I spawn in entities with a 2D model like this mod?

[NickBurnett]

If any of you are familiar with JinRyuu's DBC mod, I'm trying to replicate his Aura system, but this is also for me learning exactly how entities work. In his code, he registers his Entity, Model, and Renderer just like any other entity, but the entity sprite is 2D, and it gives off an Aura effect. How could I create something similar?

Which part are you having trouble with?
Displaying a 2D sprite as a visual model?

or

Finding all nearby entities? (the aura)

I'm having trouble with the entire concept. Am I supposed to create the Entity, make a 2D sprite, give it a basic model & renderer? Also, if I sent you a video of how Jin did it in his mod, would you be able to help me more in understanding exactly what is going on?

You...:

1. Create an entity
2. Give it a model and renderer (this will be the 2D sprite)
3. Code the aura effect inside the entity

Well obviously, however I'm wondering if I could get a quick rundown example of how this would work. I'm not asking for anything too serious, just an idea of what my could should be similar to that way I have structure to go off of.

If your looking at how to render a 2d model look at the vanilla Render Snowball class. A couple modifications to it (making the image load from a file rather than the TextureMap etc.) and it should work perfectly
