How to disable attack animation

[Greyscail]

I've read several threads about this from older versions of forge but I just can't get this to work. I've tried stopping the animation in the AttackEntityEvent, MouseEvent, and PlayerInteractEvent but none of them seem to be able to stop the animation. I've tried:

 

player.resetActiveHand();
player.swingProgressInt = -1;
player.isSwingInProgress = true;

 

I've even tried canceling the events right when they start but I can't stop that pesky attack animation no matter what I do. I've seen other threads say to override the onSwing method in your mod's item class but I want to cancel the attack animation for vanilla items so I'm absolutely lost. Is there a way to intercept the packet responsible for the attack animation?

just discovered RenderSpecificHandEvent and canceling that doesn't work either

Are you positive that you cancelled the event CLIENT-SIDE so that none of that renders?
