1.7.2 Projectile Rendering - Item doesn't Render

[primalfreeze]

Hey everyone,

 

I've checked everywhere, but I can't find a single thing that could be causing my issue. I'm trying to implement a basic 'fireball' using snowball as a basis but I'm not having any luck.

 

The specific problem is that while the projectile fires and impacts, it doesn't render at all.

 

I have added break points into the RenderKBFireball class but they do not fire.

 

My four classes are:

KBFireball - contains the item, it's onItemRightClick event, it's presence in creative mode, icon etc.

KBEntityFireBall - inheriting from EntityThrowable controls the onImpact

RenderKBFireball - the render class, pretty much a direct copy of RenderSnowball

KBClasses - the main mod file containing the definition and the registry etc.

 

A few things worth noting:

In KBFireball, I'm alternating between firing an actual snowball and my Fireball itself. The fact that the snowball shows is telling me this class is fine.

 

I suspect if anything, it has something to do with my registering of items, but I've tried a lot of variations and had no luck.

 

All of this compiles and runs as well, so no code errors.

 

Thanks in advance

Where do you register the entity?

[primalfreeze]

@Eternaldoom - that was enough for me to figure it all out. I somehow glossed over the registering of an entity in all the examples I found. I suspect because I was looking for other problems, not chunks that were missing.

 

So thanks heaps.

 

For recordkeeping purposes, here is the added code (added in KBClasses.preInit)

 

  Reveal hidden contents

 

    EntityRegistry.registerGlobalEntityID(KBEntityFireball.class, "KBFireball", uid);

    EntityRegistry.registerModEntity(KBEntityFireball.class, "KBFireball", uid, this, 80, 10, true);

 

 

 

This topic is now solved but I can't see anything letting me mark it as such.
