player being weird when it stops moving

so the player's animation is set to running when it's moving, but whenever its on stopped, the player goes up in the air a little before dropping on the ground.Why does that happen and how do i fix it???

gotta see capx or screen shoot of your events so we can see how you set it up

I'm guessing your ImagePoint origin is not consistent between your frames or your sprite frames are different sizes. Keep your canvas the exact same size across all your frames for both "running" and "idle" and make sure your origin point is in the same location.
