Question

I need to animate a AnimatableBody2D using AnimationPlayer. I'm using Bezier curve for smooth and controlled behaviour, but I see jitter at 0.5sec. I don't know how to fix it. In this clip I animated a simple CharacterBody2D to see if this issues is only with AnimatableBody2D, but looks like its AnimationPlayer issue. Please help me make this animation smoother.

It seems smooth to me

Try to make a new scene with no scripts etc. to see if this will be the same there.
It might also be just a visual rendering glitch. Try zooming in on the shape in the editor to see if the jitter is actually there.
