after creating my class to render my custom mob (a fish) my minecraft (that is in eclipse) would crash every time i tried to run it. I will post the code and the crash log. I did use the vanilla cow render. If that is the problem, can you please tell me what i should use?

Thanks!

The first line of your stack trace says you are calling a method on a null object in the constructor of your class Fish, on line 45.

 

java.lang.NullPointerException: Initializing game

  at com.extraores.model.Fish.<init>(Fish.java:45)

 

Your problem is not in class RenderMyFishMob. Go to line 45 of class Fish and look for an object you are calling a method on. For some reason, it is null.

your Class RenderMyFishMob is not correct to, you must return your return location instead of null:

@Override

  protected ResourceLocation getEntityTexture(Entity p_110775_1_) {

      return null;

  }

 

But I think you have more problems than that.

Thanks for replying. I looked at my Fish.class and didn't find anything that i used or that was null. Also, what should i return instead of null? The class location or the texture location?

 

Here is my code in Fish.class (it is a techne model file):

Thanks for helping guys!

You set RightFin.mirror to true twice then set it to false. I have had this problem with techne before. Just take out the extra RightFin.mirror s and it should work.

You have set field mirror on Right_Fin before you initialize it on the next line, so, Right_Fin is null.

 

      Right_Fin.mirror = true;
      Right_Fin = new ModelRenderer(this, 0, 0);

 

If you are running from inside Eclipse (and you should be during development) exceptions and their stacktraces are printed to the console window. The file name and line number of each call are links that are hightlighted in red and underlined. You can click on the link and it will bring you directly to the line in the file where the call was made. In your case, clicking on Fish.java:45 will open Fish.java with the line

 

Right_Fin.mirror = true;

 

highlighted. There is only one thing that can be null here.

 

Incidentally, does Techne really generate uppercase variable names?

 

Yes, that is the exact code that techne generated (other than the entity stuff in the last 10 or so lines).

techne code always has to be doctored before it can be used for any coding in minecraft. It generates often completely buggy code.
