Hi, I'm working on a Wizardry mod (harry potter themed) and I am having a BIG issue with my shield charm.

Currently it does not render at all.

EntityShieldCharm

public class EntityShieldCharm extends EntityThrowable {
	//public AxisAlignedBB box;
	public List<Entity> caster;
	public float size;
	public EntityShieldCharm(World arg0) {
		super(arg0);
		this.caster = new ArrayList();
		this.motionX = 0;
		this.motionY = 0;
		this.motionZ = 0;
	}
	
	public EntityShieldCharm(World arg0, EntityLivingBase caster, float size) {
		super(arg0, caster);
		this.caster = new ArrayList();
		this.caster.add(caster);
		//this.caster.addAll(world.getEntitiesWithinAABB(Entity.class, this.getEntityBoundingBox()));
		this.setSize(size, size);
		this.size = size;
		//this.accelerationX = 0;
		//this.accelerationY = 0;
		//this.accelerationZ = 0;
		this.motionX = 0;
		this.motionY = 0;
		this.motionZ = 0;
	}
	public void readFromNBT(NBTTagCompound nbt) {
		super.readFromNBT(nbt);
		NBTTagList list = (NBTTagList) nbt.getTag("casters");
		List<Entity> entities = world.getEntitiesWithinAABB(Entity.class, this.getEntityBoundingBox());
		for (NBTBase n : list) {
			String uuid = n.toString();
			for (Entity e : entities) {
				if (e.getPersistentID().toString() == uuid) caster.add(e);
			}
		}
	}
	
	public NBTTagCompound writeToNBT(NBTTagCompound nbt) {
		super.writeToNBT(nbt);
		NBTTagList list = new NBTTagList();
		for (Entity e : caster) {
			list.appendTag(new NBTTagString(e.getPersistentID().toString()));
		}
		nbt.setTag("casters", list);
		return nbt;
	}
	public boolean allow(Entity e) {
		
		return caster.contains(e);// || !isHeadingTowards(e);
	}
	@Override
	public void onUpdate() {
		List<Entity> entities = world.getEntitiesWithinAABB(Entity.class, this.getEntityBoundingBox());
		for (Entity e : entities) {
			if (allow(e)) continue;
			double mx = e.motionX, my = e.motionY, mz = e.motionZ;
			e.setPositionAndUpdate(e.lastTickPosX, e.lastTickPosY, e.lastTickPosZ);
			e.setVelocity(-mx, -my, -mz);
			e.velocityChanged = true;
			Class c = e.getClass();
			try {
				Field xf = c.getField("accelerationX");
				Field yf = c.getField("accelerationY");
				Field zf = c.getField("accelerationZ");
				try {
					double x = xf.getDouble(e), y = yf.getDouble(e), z = zf.getDouble(e);
					xf.setDouble(e, -x);
					yf.setDouble(e, -y);
					zf.setDouble(e, -z);
				} catch (IllegalArgumentException e1) {
				} catch (IllegalAccessException e1) {
				}
			} catch (NoSuchFieldException e1) {
			} catch (SecurityException e1) {
				e1.printStackTrace();
			}
		}
	}
	public boolean attackEntityFrom(DamageSource c, float a) {
		return false;
	}
	public boolean isHeadingTowards(Entity e) {
		double x = e.posX,
				y = e.posY,
				z = e.posZ;
		double nx = e.posX - e.motionX, ny = e.posY - e.motionY, nz = e.posZ - e.motionZ;
		if (MathHelper.sqrt(x * x + y * y + z * z) < MathHelper.sqrt(nx * nx + ny * ny + nz * nz)) return true;
		return false;
	}
	
	public boolean canBeCollidedWith() {
		return false;
	}

	@Override
	protected void onImpact(RayTraceResult arg0) {}

}

WizardryMod

@Mod(modid = WizardryMod.MODID, version = WizardryMod.VERSION, name = WizardryMod.NAME)
public class WizardryMod {
	public static final String MODID = "giantwizardry", VERSION = "1.0.0-1.12.2", NAME = "Giant's Wizardry";
	public static CustomCreativeTab tab = new CustomCreativeTab(MODID, WizardryItems.wand);
	public static WizardryMod instance = new WizardryMod();
	@SidedProxy(clientSide="mods.giantnuker.wizardry.proxy.ClientProxy")
	public static IProxy proxy;
	@EventHandler
	public void preInit(FMLPreInitializationEvent event) {
		proxy.preInit(event);
		WizardryItems.init();
		PacketUpdateCapability.init();
		
		CapabilityManager.INSTANCE.register(WizardryCapability.class, new WizardryCapability.Storage(), WizardryCapability.Implementation.class);
		MinecraftForge.EVENT_BUS.register(new WizardryHandler());
		
		//EntityRegistry.registerModEntity(new ResourceLocation(WizardryMod.MODID, "entitySpellShield"), EntityShieldCharm.class, "shieldSpell", 999, this, 0, 0, false);
	}
	
	@EventHandler
	public static void init(FMLInitializationEvent event) {
		proxy.init(event);
		
	}
}

ClentProxy

public class ClientProxy implements IProxy {

	@Override
	public void preInit(FMLPreInitializationEvent event) {
		RenderingRegistry.registerEntityRenderingHandler(EntityShieldCharm.class, new ShieldCharmRenderFactory());
	}

	@Override
	public void init(FMLInitializationEvent event) {
		
	}

	@Override
	public void postInit(FMLPostInitializationEvent event) {
		
	}

}

ShieldCharmRenderFactory

public class ShieldCharmRenderFactory implements IRenderFactory {

	@Override
	public Render createRenderFor(RenderManager arg0) {
		return new RenderShieldSpell(arg0);
	}

}

RenderShieldSpell

public class RenderShieldSpell extends Render<EntityShieldCharm>{
	public ModelRectCube model = new ModelRectCube();
	public RenderShieldSpell(RenderManager rm) {
		super(rm);
	}

	@Override
	protected ResourceLocation getEntityTexture(EntityShieldCharm arg0) {
		return new ResourceLocation("textures/entity/creeper/creeper_armor.png");
	}
	
	@Override
	public void doRender(EntityShieldCharm charmEnt, double x, double y, double z, float yaw, float partialTicks) {
		this.bindTexture(getEntityTexture(charmEnt));
		GlStateManager.pushMatrix();
		GlStateManager.translate(x, y, z);
		model.render(charmEnt, 0, 0, 0, 0, 0, charmEnt.size);
		GlStateManager.popMatrix();
		super.doRender(charmEnt, x, y, z, yaw, partialTicks);
	}

}

And ModelRectCube

public class ModelRectCube extends ModelBase {
	public void render(Entity entity, float a0, float a1, float a2, float a3, float a4, float a5) {
		ModelRenderer cube = new ModelRenderer(this, 0, 0);
		cube.addBox(0, 0, 0, 16, 16, 16);
		cube.render(a5);
	}
}

Also, when I press F3 + B I do not see it's bounding box, but it is there sience it repels everything.

Your entity registration is commented out. Why?

I was getting a devide by 0 exception before i realised trackingRange & the update stuff were the same thing.

trackingRange is now 100 but I still need to know what is wrong with the render script - all it does is changes it from a white cube to air, but i see the bounding box. The reason I did not before is because the server tells the client about the entity via it's registration id.
