"Physics Interpolation" jitter when updating Position

Hey,

I am new to Godot and doing the introduction 2D tutorial. I’m moving the sprite by updating its Position in the PhysicsProcess(). When I set the Physics FPS to 30 and turn on Physics Interpolation, the sprite moves visibly with 30 FPS, there is no smoothing at all. When I add my own simple interpolation code to interpolate between the previous and the current positions, it’s butter smooth. Is this feature currently buggy, or I’m doing something wrong?

Thanks

You don’t normally move physics object directly. Depending on what kind of physics object it is (Rigid, Kinematic etc…) you use something like move_and_slide() or move_and_collide().

I see. In case I don’t use physics to move my objects, then it’s up to me to interpolate. Thanks for the answer!

If you’re not using physics, I would use _process() instead of _physics_process().
