# SCA_ObjectActuator(SCA_IActuator)¶

base class — SCA_IActuator

class SCA_ObjectActuator(SCA_IActuator)

The object actuator (“Motion Actuator”) applies force, torque, displacement, angular displacement, velocity, or angular velocity to an object. Servo control allows to regulate force to achieve a certain speed target.

force

The force applied by the actuator.

Type

Vector((x, y, z))

useLocalForce

A flag specifying if the force is local.

Type

boolean

torque

The torque applied by the actuator.

Type

Vector((x, y, z))

useLocalTorque

A flag specifying if the torque is local.

Type

boolean

dLoc

The displacement vector applied by the actuator.

Type

Vector((x, y, z))

useLocalDLoc

A flag specifying if the dLoc is local.

Type

boolean

dRot

The angular displacement vector applied by the actuator

Type

Vector((x, y, z))

Note

Since the displacement is applied every frame, you must adjust the displacement based on the frame rate, or you game experience will depend on the player’s computer speed.

useLocalDRot

A flag specifying if the dRot is local.

Type

boolean

linV

The linear velocity applied by the actuator.

Type

Vector((x, y, z))

useLocalLinV

A flag specifying if the linear velocity is local.

Type

boolean

Note

This is the target speed for servo controllers.

angV

The angular velocity applied by the actuator.

Type

Vector((x, y, z))

useLocalAngV

A flag specifying if the angular velocity is local.

Type

boolean

damping

The damping parameter of the servo controller.

Type

short

forceLimitX

The min/max force limit along the X axis and activates or deactivates the limits in the servo controller.

Type

list [min(float), max(float), bool]

forceLimitY

The min/max force limit along the Y axis and activates or deactivates the limits in the servo controller.

Type

list [min(float), max(float), bool]

forceLimitZ

The min/max force limit along the Z axis and activates or deactivates the limits in the servo controller.

Type

list [min(float), max(float), bool]

pid

The PID coefficients of the servo controller.

Type

list of floats [proportional, integral, derivate]

reference

The object that is used as reference to compute the velocity for the servo controller.

Type

KX_GameObject or None
