--- name: ControllerManager last_updated: 2026-06-11T23:11:56Z inherits: - Instance - Object type: class memory_category: Instances summary: "Manages simulated motion control for its assigned ControllerManager.RootPart ." --- # Class: ControllerManager > Manages simulated motion control for its assigned > [ControllerManager.RootPart](/docs/reference/engine/classes/ControllerManager.md) . ## Description The [ControllerManager](/docs/reference/engine/classes/ControllerManager.md) instance manages simulated motion control for its assigned [ControllerManager.RootPart](/docs/reference/engine/classes/ControllerManager.md). It can be used to build a physics-based character controller. ## Properties ### Property: ControllerManager.ActiveController ```json { "type": "ControllerBase", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Behavior", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` The [ControllerBase](/docs/reference/engine/classes/ControllerBase.md) that is set to be activated on the character. It does not guarantee that the specified [ControllerBase](/docs/reference/engine/classes/ControllerBase.md) is, in fact, active. If the [ControllerBase](/docs/reference/engine/classes/ControllerBase.md) cannot be activated for whatever reason, such as being outside of the character's [WorldRoot](/docs/reference/engine/classes/WorldRoot.md) or no [Part](/docs/reference/engine/classes/Part.md) being found to use as the floor for a [GroundController](/docs/reference/engine/classes/GroundController.md), it will remain set and the [ControllerManager](/docs/reference/engine/classes/ControllerManager.md) will attempt to activate it in the next frame. This property can be set to `nil` to disable the physics controller. ### Property: ControllerManager.BaseMoveSpeed ```json { "type": "float", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Behavior", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` The base linear movement speed used by all controllers. Controllers individually customize speed by setting the [ControllerBase.MoveSpeedFactor](/docs/reference/engine/classes/ControllerBase.md) property. ### Property: ControllerManager.BaseTurnSpeed ```json { "type": "float", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Behavior", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` The base angular turning speed used by all controllers to align the character to face the desired direction. ### Property: ControllerManager.ClimbSensor ```json { "type": "ControllerSensor", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Behavior", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` A reference to the sensor data used while a [ClimbController](/docs/reference/engine/classes/ClimbController.md) is active. A [ClimbController](/docs/reference/engine/classes/ClimbController.md) will use the [ControllerPartSensor.HitPart](/docs/reference/engine/classes/ControllerPartSensor.md), [ControllerPartSensor.HitFrame](/docs/reference/engine/classes/ControllerPartSensor.md), and [ControllerPartSensor.HitNormal](/docs/reference/engine/classes/ControllerPartSensor.md) for climb movement computations. Typically a [ControllerPartSensor](/docs/reference/engine/classes/ControllerPartSensor.md) set to [SensorMode.Ladder](/docs/reference/engine/enums/SensorMode.md) is used here. Otherwise, you can override the sensor's outputs to direct what sensor data you want the [ClimbController](/docs/reference/engine/classes/ClimbController.md) to use. ### Property: ControllerManager.FacingDirection ```json { "type": "Vector3", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Input", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` The unit vector describing the desired direction to face. Aligns the [LookVector](/docs/reference/engine/datatypes/CFrame.md) of the [ControllerManager.RootPart](/docs/reference/engine/classes/ControllerManager.md) to this. Any [Vector3](/docs/reference/engine/datatypes/Vector3.md) assigned will be automatically unitized. ### Property: ControllerManager.GroundSensor ```json { "type": "ControllerSensor", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Behavior", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` A reference to the sensor data used while a [GroundController](/docs/reference/engine/classes/GroundController.md) is active. A [GroundController](/docs/reference/engine/classes/GroundController.md) will use the [ControllerPartSensor.HitPart](/docs/reference/engine/classes/ControllerPartSensor.md), [ControllerPartSensor.HitFrame](/docs/reference/engine/classes/ControllerPartSensor.md), and [ControllerPartSensor.HitNormal](/docs/reference/engine/classes/ControllerPartSensor.md) for ground movement computations. Typically a [ControllerPartSensor](/docs/reference/engine/classes/ControllerPartSensor.md) set to [SensorMode.Floor](/docs/reference/engine/enums/SensorMode.md) is used here. Otherwise, you can override the sensor's outputs to direct what sensor data you want the [GroundController](/docs/reference/engine/classes/GroundController.md) to use. ### Property: ControllerManager.MovingDirection ```json { "type": "Vector3", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Input", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` The vector describing the desired direction to move in, with a magnitude between 0 and 1. This is multiplied by [BaseMoveSpeed](/docs/reference/engine/classes/ControllerManager.md) to determine a final target move velocity. The [RootPart](/docs/reference/engine/classes/ControllerManager.md) will attempt to move in this direction based on the rules defined by the [ActiveController](/docs/reference/engine/classes/ControllerManager.md). ### Property: ControllerManager.RootPart ```json { "type": "BasePart", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Behavior", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` The [BasePart](/docs/reference/engine/classes/BasePart.md) where the controller's forces and torques are applied. With a typical [Humanoid](/docs/reference/engine/classes/Humanoid.md)-based character, the [Humanoid.RootPart](/docs/reference/engine/classes/Humanoid.md) is assigned as the [ControllerManager.RootPart](/docs/reference/engine/classes/ControllerManager.md). ### Property: ControllerManager.UpDirection ```json { "type": "Vector3", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Input", "capabilities": [ "AvatarBehavior" ], "simulationAccess": true } ``` ## Inherited Members ### From [Instance](/docs/reference/engine/classes/Instance.md) -
