# Motion Actuator: Servo Control  Motion Type: Servo Control
• Tries to maintain the set linear velocity
Reference Object:
• Object used as the reference base for setting the Linear Velocity

• Example:
• If the reference object is a moving platform, a player standing on the platform would move relative to the platform
• Leave blank to use the world as the reference base
Linear Velocity:
• X: Linear Velocity on the X axis

• Y: Linear Velocity on the Y axis

• Z: Linear Velocity on the Z axis
Linear Velocity L:
• Enabled:
• Use the Local (object axis) axis
• Disabled:
• Use the World axis
X:
• Enabled:
• Limits the force that the Servo Control can use on the X axis to try and maintain the target linear velocity
• Disabled:
• The Servo Control uses whatever force is necessary on the X axis to maintain the target linear velocity
• Max:
• Upper limit of the force that the Servo Control is allowed to use on the X axis
• Min:
• Lower limit of the force that the Servo Control is allowed to use on the X axis
Y:
• Enabled:
• Limits the force that the Servo Control can use on the Y axis to try and maintain the target linear velocity
• Disabled:
• The Servo Control uses whatever force is necessary on the Y axis to maintain the target linear velocity
• Max:
• Upper limit of the force that the Servo Control is allowed to use on the Y axis
• Min:
• Lower limit of the force that the Servo Control is allowed to use on the Y axis
Z:
• Enabled:
• Limits the force that the Servo Control can use on the Z axis to try and maintain the target linear velocity
• Disabled:
• The Servo Control uses whatever force is necessary on the Z axis to maintain the target linear velocity
• Max:
• Upper limit of the force that the Servo Control is allowed to use on the Z axis
• Min:
• Lower limit of the force that the Servo Control is allowed to use on the Z axis
Proportional Coefficient:
• Determines the reaction of the Servo Control to the difference between the actual linear velocity and target linear velocity

• Range:
• 0.00 to 200.00
Integral Coefficient:
• Determines the reaction of the Servo Control based on the sum of recent errors

• Range:
• 0.00 to 3.00
Derivate Coefficient:
• Determines the reaction of the Servo Control based on the rate at which the error has been changing

• Range:
• -100.00 to 100.00
Note:
• Uses as much force is needed to try to maintain the set Linear Velocity

• Force applied:
• Game object moves at the set Linear Velocity
• Force removed:
• Game object keeps moving until gravity and friction slows it to a stop  Motion:
• The type of Actuator
Name:
• Actuator name
Pin:
• Enabled:
• Always display the Actuator
• Disabled:
• Only display when the State Mask group the Actuator is linked to is being displayed
Checkbox:
• Enabled:
• Actuator is turned on
• Disabled:
• Actuator is turned off
Note:
• Actuators can be connected to more than one controller

• Actuators connected to a controller(s) belong to the same State Mask group(s) as the controller(s)
