How to animate a chracter smoothly?

Hi!

I want to make a game, where the player is a stickman, so the legs and arms behave smooth. Just like in the mobile game “I’m Ping Pong King :)”. Which technique do I have to use for that, since I only know how to animate with bones (which is of course not really smooth)?

Thank you!

bone animation can be really smooth, look at kinematic and inverse kinematic animation.
