RigidBody jitter on player when running in circles

JackAnimated

Unity 6.5 (6000.5.2f1)
AC v1.86.4

I am making an action fps game and switching out the Character Controller for a Rigidbody with collider on the SamplePlayerFP gameobject has the effect of making running in circles jitter the movement or camera - not smooth. I have played around with settings on the game object for a couple of evenings without success of solving the jitter.

As AC is generally made for slower paced games, is the rigidbody jitter a known accepted side effect and best that I write or obtain a new player object script more suited to fast paced action, or is there a fix for the AC version?

many thanks.

Generally the Character Controller does fare better for the style of game AC is intended for. For action games, I would say it's worth looking into a more dedicated asset as a motion controller for a fast-paced action game is a large and complex topic in and of itself.

However, for the original issue: open up AC's Char script and look for the first SetRotation function around line 1762. Above:

TransformRotation = _rotation;

add:

if (_rigidbody && useRigidbodyForMovement) _rigidbody.MoveRotation(_rotation);

Does that reduce the jittering?

Fantastic Chris! That has completely fixed the issue. Smooth as butter now.

On a related note, what is the difference between the functions of
"Turn Speed"
"Head turn speed"
"freelook sensitivity"

"movement smoothing" and "Destination Accuracy"
"Free-aim Acceleration" and "Max Free-aim Speed"

as well as how they effect each other, in laymans terms?

• Turn Speed: The character's body-turning speed when under AC's control (for a Player, this is during cutscenes)
• Head turn speed: The speed of the head when turning due to IK (not the same as free-aiming)
• Freelook sensitivity: The speed multiplied for free-aiming

For First-person camera speed, it's the last one that you'll want to tweak

• Movement smoothing: Applies a Lerp to the movement input, to give it a smoother acceleration
• Destination accuracy: How close to a character's destination is "close enough" for it to be considered arrived

These two are independent and don't affect each other

• Free-aim Acceleration: The scale of the Lerp to apply to the free-aim Input. Higher values mean more responsiveness when free-aiming
• Max Free-aim Speed: A maximum cap applied the magnitude of the free-aim input. Lower values mean the max turn speed is lowered
