3D Custom Item Model Help

[MrNegaBlox]

I was making a custom 3D model for an item, yet once I go in 3rd person, I get a certain Stack Trace, I am wondering what is causing it. BTW, I'm using Techne to make the 3D model and I got the tutorial from iChun.

Read your f*ing error.

 

Null pointer at ItemRender line 45.

 

Look at the f*ing code that's there and figure out which object is null.  It's really f*ing obvious.

 

(Hint, there's only one object there that is using references to its properties or methods)

[MrNegaBlox]

Look, I did, but I couldn't find the error or any tutorial. It lead to the render class and it had everything right from the tutorial. That's the whole reason I sent the code here

[Draco18s]

Here's the line that is throwing the error

phoenix.render((Entity)data[1], 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0625f);

Hmm.  Lets see.  The only object here is phoenix, lets go see where that's used elsewhere.

protected ModelPhoenixBlastereModel phoenix;

 

THAT'S FUNNY, ITS NEVER ASSIGNED A VALUE.  LAWL.  NO WONDER IT'S NULL!

[MrNegaBlox]

Ok I may sound and probably am stupid with Java (I'm new, intermediate, not fluent, I learn from tutorials, I get what they say, but I have things to learn), But How would I assign this a value? I mean I get that is referencing the class, but how do I make it NOT null, If you won't answer, then others will. Cause I don't know what values to put to make it not null, if I don't get it, ill look up on iChuns tut again.

protected ModelPhoenixBlastereModel phoenix = new ModelPhoenixBlastereModel();

 

Possibly? Although I have no idea exactly what ModelPhoenixBlastereModel is other than badly named...

[Draco18s]

The dude with five posts figured it out.

 

You (the original poster) need to go learn Java before tinkering around with Minecraft some more.  This is a basic concept you need to know before modding can begin.
