Protocol lib Falling block

I basically made a Hide and seek plugin, using protocol lib I disguise a player as a falling block. The problem is when a seeker hits the blocks it shoots the blocks 10 blocks in the direction it was hit.

Instead of seeing a falling block being moved a couple blocks it moves continuously in a vector until it loses velocity.

How do I make it so that the falling block only moves 2 blocks and then stops?

It's all a visual glitch, but I'm not sure how to fix it.

Thanks
