Prevent using item to change player speed

[Kahel]

Hey, I'm trying to make an item not slowing down the player when it's used.

For the moment I made a function in my Item extended class

	@Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn)
    {
		playerIn.setActiveHand(handIn);
      	//...
        return new ActionResult<ItemStack>(EnumActionResult.PASS, playerIn.getHeldItem(handIn));
    }

 

I can't even find where in the code the speed is changing when an item is used.

Thanks for your help.

I'm looking anywhere in the source code but can't find why the player is slowed down when he's using an item
