advice for newers here:

start keyframing you work first and right now, avoid procrastinating and do at least this one thing at least you finished something, keyframe it and turn it 4pfs that’s your current animation

turn it 8 10 or 12 PFS and put ONE IN BETWEEN EVERY FRAME, and decide the path that your stick figure will go through I believe it’s called arcs and here you can put SFX overshots and so one

now turn it 24fps and put 2 in betweens, one if you want to imply speed and one in between the standing character and when it moves to imply momentum or gaining speed

this will all sound weird but take a screenshot AND GO FINISH YOUR ANIMATION THAT’S WHY YOU CAN’T ANIMAT WHAT THE HELL ARE YOU DOING IN STICKNODES.COM, GO DO SOMETHING GOD
