Hello, I have a gun and I am trying to figure out how to get it to aim. I looked at the bow code but.. I don't understand it. I have 2 jsons, A version of my gun that IS aiming and a version of my gun that IS NOT aiming. How do I switch between them?

 

public class M16A4 extends Item implements IHasModel
{
	
	int Firerate = 8;
	int clipsize = 25;
	int kick = 5;
	int ReloadTime = 30;
	
	
	public M16A4(String name, CreativeTabs tab) 
	{
		setUnlocalizedName(name);
		setRegistryName(name);
		setCreativeTab(tab);
		setMaxStackSize(1);
		setMaxDamage(clipsize + 1);
		
		ModItems.ITEMS.add(this);
	}
	
	@Override
	public void addInformation(ItemStack stack, World worldIn, List<String> tooltip, ITooltipFlag flagIn) 
	{
		tooltip.add(TextFormatting.YELLOW + "Impact: " + TextFormatting.GREEN + "::::" + TextFormatting.RED + "::::::");
		tooltip.add(TextFormatting.YELLOW + "Range:  " + TextFormatting.GREEN + ":::::" + TextFormatting.RED + ":::::");
		tooltip.add(TextFormatting.YELLOW + "Clipsize: " + TextFormatting.GREEN + "25");
		super.addInformation(stack, worldIn, tooltip, flagIn);
	}
	
	@Override
	public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) 
	{
		
		ItemStack itemstack = playerIn.getHeldItem(handIn);
		
		if (!playerIn.capabilities.isCreativeMode)
		{
			if(itemstack.isItemDamaged())
			{
				if(itemstack.getItemDamage() >= clipsize)
				{
					if(playerIn.inventory.hasItemStack(new ItemStack(ModItems.M16AMMO)))
					{
						EntityBullet entity = new EntityBullet(worldIn, playerIn, 2.0F, 50);
						itemstack.setItemDamage(-clipsize - 1);
						playerIn.inventory.clearMatchingItems(ModItems.M16AMMO, 0, 1, null);
						playerIn.getCooldownTracker().setCooldown(this, ReloadTime);
						worldIn.playSound(playerIn,	playerIn.posX, playerIn.posY, playerIn.posZ, SoundHandler.RELOAD_RIFLERELOAD, SoundCategory.MASTER, 1, 1);
					}
				}
				else
				{
					playerIn.getCooldownTracker().setCooldown(this, Firerate);
					if (!worldIn.isRemote)
					{
						EntityBullet entity = new EntityBullet(worldIn, playerIn, 3.5F, 200);
						entity.shoot(playerIn, playerIn.rotationPitch, playerIn.rotationYaw, 0.0F, 1.5F, 0.0F);
						worldIn.spawnEntity(entity);
						itemstack.damageItem(1, playerIn);
						
					}
					worldIn.playSound(playerIn,	playerIn.posX, playerIn.posY, playerIn.posZ, SoundHandler.GUN_RIFLE_SHOOT, SoundCategory.MASTER, 1, 1);
				}
				
			}
			else
			{
				//First Bullet
				playerIn.getCooldownTracker().setCooldown(this, Firerate);

					worldIn.spawnEntity(entity);
					itemstack.damageItem(1, playerIn);
					
				}
				worldIn.playSound(playerIn,	playerIn.posX, playerIn.posY, playerIn.posZ, SoundHandler.GUN_RIFLE_SHOOT, SoundCategory.MASTER, 1, 1);

Use the Property Override like the Bow does
