[SOLVED] [1.12.2] Create Custom Projectile (similar to arrow)

[Cadiboo]

Before I start - I've spent a few days now looking at other peoples posts, but most seem to be related to rendering which I don't care about yet, are for older versions of minecraft, or when I try to use their solutions they don't work.

I've been working on the same mod (Tutorial Mod) for a long time so it could be a compounded error. Im planning to finish everything before moving the code to a new package with a better name (I haven't decided on the name yet)

I'm trying to create a railgun (currently works perfectly using arrows), and now I need a custom projectile for it - I've tried copying and modifying the arrow code many time but now I trying to at least start off with a projectile that extends EntityThrowable. I've put in basic code for the projectile and it should work.

But I've tried about 5 different ways (with many variations on each) of registering my entity and I can't get any of them to work. Every time I launch the game it crashes when it tries to register my entity.

Im currently using EntityRegistry.registerModEntity in my PreInit

Any help would be greatly appreciated, also - I'm relatively new in java but I do know other Object Oriented languages like PHP, JavaScript (I've previously been doing web design etc) and also OSX Application languages like Swift -  so if its something really simple that you think I should know please point it out!

Also my rendering class though it does nothing

RenderRailGunProjectile.Java

package com.cadiboo.tutorial.renderer;

import net.minecraft.client.renderer.RenderItem;
import net.minecraft.client.renderer.entity.RenderManager;
import net.minecraft.client.renderer.entity.RenderSnowball;
import net.minecraft.entity.Entity;
import net.minecraft.item.Item;

public class RenderRailGunProjectile extends RenderSnowball<Entity>{

	public RenderRailGunProjectile(RenderManager renderManagerIn, Item itemIn, RenderItem itemRendererIn) {
		super(renderManagerIn, itemIn, itemRendererIn);
		// TODO Auto-generated constructor stub
	}

}

 

Probably should have put this at the top, my Crash Report - note that it crashes when registering the projectile
