Turn off hand movement?

This may not be the best way to go about this, but on onItemRightClick your gonna want to return a ActionResult.resultFail(yourItem). This will cancel the "animation". Here is an example I use in one of my mods.

    @Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) {
        ItemStack itemStack = playerIn.getHeldItem(handIn);
        if (!worldIn.isRemote)
        {
            LazyOptional<IPlayerHandler> player_cap = playerIn.getCapability(PlayerProvider.CAPABILITY_PLAYER, null);
            IPlayerHandler playerHandler = player_cap.orElse(new PlayerCapability());

            if (itemStack.hasTag() && !itemStack.getTag().getString("entityaffiliation").equalsIgnoreCase(""))
            {
                playerHandler.setPlayerEntityAffiliation(itemStack.getTag().getString("entityaffiliation"));
                playerIn.sendMessage(new StringTextComponent("Added Contract"));
                NetworkLoader.INSTANCE.send(PacketDistributor.PLAYER.with(() -> (ServerPlayerEntity) playerIn), new PacketPlayerEntityAffiliationSync(playerHandler.returnPlayerEntityAffiliation()));
                NetworkLoader.INSTANCE.sendToServer(new PacketAdvancement("scroll"));
            }
        }
        playerIn.addStat(Stats.ITEM_USED.get(this));
        if (!playerIn.abilities.isCreativeMode) {
            itemStack.shrink(1);
        }
        return ActionResult.resultSuccess(itemStack); THIS IS THE PART THAT IS IMPORTANT
    }

DISREGARD THE OTHER CODE JUST LOOK AT THE RETURN STATEMENT!!!

OOPS I forgot that was a succes return!!! USE THIS INSTEAD: 

return ActionResult.resultFail(itemStack);

I think someone should open a ticket to make this an option.

i suport it

if anybody wants to know, i manage to 'fix' this manually on code (on 2020.4/2020.3):

//@Override
        //public UseAction getUseAction(ItemStack stack) {
        //    return UseAction.BOW;
        //}            <-------------- DISABLE THIS PART HERE

        @Override
        public ActionResult<ItemStack> onItemRightClick(World world, PlayerEntity entity, Hand hand) {
            entity.setActiveHand(hand);
            return new ActionResult(ActionResultType.FAIL, entity.getHeldItem(hand));        //<------------- Change SUCESS to FAIL here
            
        }

guns dont move when shoting now :)

Did you not read my first post......................... lol..........

Howdy stranger! So how would one go about inserting this code into a procedure? because as far as I know it only uses code blocks.

You got to lock the class and change the code there. It's not applicable to do in a procedure.

So I went about adding this script to my mod and I received this;
