Flying is bugged when colliding with the ground

I wrote a flying script and it works fine until I collide with the ground.

when I collide with the ground the camera and the player shake and after going up it slowly moves even when not touching anything.

you can test it yourself by putting it in Starter charcter scripts

You are changing the CFrame of the character’s HumanoidRootPart which interpolates instead of physically rotating. Which is why whenever you physically collide with the ground, it jitters around.

So instead, you can use a BodyGyro. You can adjust it’s D and P to make it as snappy as directly changing the CFrame.
