[Solved]NPE on Custom Block Model setRotation

[Arcadius]

[Reposting because I thought this was not up to standards, but I think I was wrong]

 

Hi there! First time modder but I'm experienced with Java through my time in school. I've been playing around with various modding tutorials over the past few days, but I recently got stuck when I tried to jump into creating a custom block model. I may have been a little too eager, and I should probably go make sure I'm versed in the basics. But Neale Gaming's tutorial's been fairly helpful.

 

Anyways! I got this error in the setRotation code of my custom block's .java file

 

 

package assets.runicweapons.models;

import net.minecraft.client.model.ModelBase;
import net.minecraft.client.model.ModelRenderer;
import net.minecraft.entity.Entity;

public class blockInscriptionTable extends ModelBase
{
  //fields
    ModelRenderer TableBase;
    ModelRenderer Leg;
    ModelRenderer Leg2;
    ModelRenderer Leg3;
    ModelRenderer Leg4;
    ModelRenderer InscriptionSet11;
    ModelRenderer InscriptionSet12;
    ModelRenderer InscriptionSet21;
    ModelRenderer InscriptionSet22;
  
  public blockInscriptionTable()

      TableBase.setTextureSize(64, 64);
      TableBase.mirror = true;
      setRotation(TableBase, 0F, 0F, 0F);
      Leg = new ModelRenderer(this, 0, 23);
      Leg.addBox(0F, 0F, 0F, 2, 8, 2);
      Leg.setRotationPoint(0F, 7F, 0F);

I must be missing something blatantly obvious here, but hopefully you guys might see something that I missed.

 

Thanks!

[RafaMv]

I see this twice:

 

      setRotation(InscriptionSet22, 0F, 0F, 0F);

 

Not sure if it would crash though.

Not sure myself, but thanks for catching that!

 

 

EDIT: OH MY GOD THAT FIXED IT. Thank you!

[RafaMv]

No problem!

 

Looking at the crash report you can see:

 

java.lang.NullPointerException

at assets.runicweapons.models.blockInscriptionTable.setRotation(blockInscriptionTable.java:111) ~[bin/:?]

 

So, I believe that you must have to define each rotation point, since you got a null pointer exception. I thought these rotations were (0,0,0) by default, but there aren't... That's good to know, haha.
