Ok, so, my initial issue was that my custom TNT was rendering as a white cube. I searched every thread I could find related to that issue, and the only real answer I found was this:

 

  Reveal hidden contents

 

So, I tried following what it said, and it seems that when I try to read the data from the DataWatcher, it throws a NullPointerException repeatedly as long as the entity exists:

 

  Reveal hidden contents

 

And here is the important part of my code:

 

  Reveal hidden contents

 

The part surrounded by try/catch is what throws the NPE. If you need to see the full file, here is a link to it on github.

Could anyone tell me what I am doing wrong?

If I helped please press the Thank You button.

My guess would be this:

 

@Override
protected void entityInit() {
	if(!worldObj.isRemote) //why is this here?
		this.dataWatcher.addObject(fuseID, Integer.valueOf(fuse));
}

 

Based on looking at what Vanilla does, e.g. minecarts:

 

    protected void entityInit()
    {
        this.dataManager.register(ROLLING_AMPLITUDE, Integer.valueOf(0));
        this.dataManager.register(ROLLING_DIRECTION, Integer.valueOf(1));
        this.dataManager.register(DAMAGE, Float.valueOf(0.0F));
        this.dataManager.register(DISPLAY_TILE, Integer.valueOf(0));
        this.dataManager.register(DISPLAY_TILE_OFFSET, Integer.valueOf(6));
        this.dataManager.register(SHOW_BLOCK, Boolean.valueOf(false));
    }

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
