Help with AAC 3.3.2 Velocity

[MasterOf13FPS]

Can some1 explain me how2code a working antivelocity for aac 3.3.2. Actually my antivelocity reduce only the taken knockback but i saw that there are some antivelocity(almost full) which bypass (with a Jump and maybe edited motion but i'm not sure). Thank you anyway.

player.motionX = 0.25;
player.motionZ = 0.25;
player.motionY = 0.1;
