ControllerManager.ActiveController
The ControllerBase that is set to be activated on the character. It does not guarantee that the specified ControllerBase is, in fact, active. If the ControllerBase cannot be activated for whatever reason, such as being outside of the character's WorldRoot or no Part being found to use as the floor for a GroundController, it will remain set and the ControllerManager will attempt to activate it in the next frame. This property can be set to nil to disable the physics controller.

ControllerManager.BaseMoveSpeed
The base linear movement speed used by all controllers. Controllers individually customize speed by setting the ControllerBase.MoveSpeedFactor property.
| Field | Value |
|---|---|
| type | float |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |

ControllerManager.BaseTurnSpeed
The base angular turning speed used by all controllers to align the character to face the desired direction.

ControllerManager.ClimbSensor
A reference to the sensor data used while a ClimbController is active. A ClimbController will use the ControllerPartSensor.HitPart, ControllerPartSensor.HitFrame, and ControllerPartSensor.HitNormal for climb movement computations. Typically a ControllerPartSensor set to SensorMode.Ladder is used here. Otherwise, you can override the sensor's outputs to direct what sensor data you want the ClimbController to use.
| Field | Value |
|---|---|
| type | ControllerSensor |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["AvatarBehavior"] |
| simulationAccess | true |
ControllerManager.FacingDirection
The unit vector describing the desired direction to face. Aligns the LookVector of the ControllerManager.RootPart to this. Any Vector3 assigned will be automatically unitized.
| Field | Value |
|---|---|
| type | Vector3 |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Input |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["AvatarBehavior"] |
| simulationAccess | true |
ControllerManager.GroundSensor
A reference to the sensor data used while a GroundController is active. A GroundController will use the ControllerPartSensor.HitPart, ControllerPartSensor.HitFrame, and ControllerPartSensor.HitNormal for ground movement computations. Typically a ControllerPartSensor set to SensorMode.Floor is used here. Otherwise, you can override the sensor's outputs to direct what sensor data you want the GroundController to use.
| Field | Value |
|---|---|
| type | ControllerSensor |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["AvatarBehavior"] |
| simulationAccess | true |
ControllerManager.MovingDirection
The vector describing the desired direction to move in, with a magnitude between 0 and 1. This is multiplied by BaseMoveSpeed to determine a final target move velocity. The RootPart will attempt to move in this direction based on the rules defined by the ActiveController.
| Field | Value |
|---|---|
| type | Vector3 |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Input |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["AvatarBehavior"] |
| simulationAccess | true |
ControllerManager.RootPart
The BasePart where the controller's forces and torques are applied. With a typical Humanoid-based character, the Humanoid.RootPart is assigned as the ControllerManager.RootPart.
| Field | Value |
|---|---|
| type | BasePart |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Behavior |
| serialization | {"can_load":true,"can_save":true} |
| capabilities | ["AvatarBehavior"] |
| simulationAccess | true |
ControllerManager.UpDirection
The unit vector describing the up direction for the character, which defaults to (0, 1, 0) (world up). Controllers under this ControllerManager use it to keep the RootPart upright and to orient direction-dependent forces. For example, a GroundController applies levitation and balancing forces along this direction, while an AirController and SwimController align the character to it. Any Vector3 assigned is automatically unitized; a zero, NaN, or infinite value is ignored.
| Field | Value |
|---|---|
| type | Vector3 |
| security | {"read":"None","write":"None"} |
| thread safety | ReadSafe |
| category | Input |
| serialization | {"can_load":true,"can_save":true} |
