Problem with the fluidity of the mouvement

Hi , I’m trying to animate the character I made, but when I add keyframes, My character just jump from pose to pose instead of making fluid mouvements. Can someone help me? I’m pretty sure it’s kind of a dumb mistake, but it happens to everyone ;)!!

In your dope sheet, check the Key>>Interpolation Mode. Constant will keep the same pose until it finds a new key frame. Try linear (moves by equal size steps from key to key) or bezier (eases in and out of the key pose).

It’s not a mistake, btw. Some animators prefer to start in constant interpolation to get the timing sorted out.
