I assume this has been posted about before, so point me.

but i cannot find a tutorial that has worked and was specifically for a custom villager with custom items.

 

however. i am stuck with this entity registering and rendering. will someone please help me with this. despite my best efforts, i cannot get my entity (NPC) to show up with an egg. something is giving me an error (asking for "()") --I'll get that eventually--

but even before rearranging thing to cause this error, it ran but without my entity.

 

here the crash report. please help me.

I'd prefer if someone could direct me to something that explains why the OBJLoader is causing me problems with it imported. But not called anywhere else.

Something is

null

on line 220 of the

P.ModelPHead

class (in the constructor). We're not telepathic, so we can't really tell you much more without seeing your code.

this.rightarm.mirror = true;

 

is the line you mentioned...

Posted
this.rightarm.mirror = true;
this.rightarm = new ModelRenderer(this, 7, 47);

 

You're trying to set a field of

this.rightarm

before you assign it a value, so it's still

null

. This causes the

NullPointerException

.

 

To be honest, your code is a mess; it looks like it was generated by MCreator or a similar program:

  • You have a bunch of random methods all over the place, some of which are doing absolutely nothing.
  • You don't have a clear separation between common and client-only code.
  • You're using global entity IDs and manually adding spawn eggs. Just use the overload of
    EntityRegistry.registerModEntity

    with the two additional

    int

    arguments and an egg will be added using those as the background/foreground colours. Global IDs aren't needed and will only cause problems.

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

thta is correct. i am just going to start from scratch yet again.

i got all the blocks and items no problem.

this entity villager crap is a pain.

 

i figured mcreator was a good alternative. but i knew it would be garbage for what im doing

Posted

Well that's a bit excessive.

But I get where you're coming from. It's over no harm done. I have deleted that whole class. And any other items to do with that specific entity and am going to go from scratch once things get back in order and running.

Sorry to offend.
