Entity Description

Entity Name: logic_measure_movement

An entity that can measure the movement of an entity relative to another entity and apply that movement to a third entity.

Entity Values


  • Name targetname <target_source>
    • The name that other entities refer to this entity by.
  • Entity to Measure MeasureTarget <target_destination>
    • Entity whose movement you want to measure.
  • Measure Reference MeasureReference <target_destination>
    • The movement of Entity to Measure will be measured relative to this entity.
  • Entity to Move Target <target_destination>
    • This entity will be moved to mimic the motions of Entity to Measure.
  • Movement Reference TargetReference <target_destination>
    • The Entity to Move will move relative to this entity.
  • Movement scale TargetScale <float>
    • A scale to divide the measured movements by, before applying those movements to the Entity to Move. 1 = target entity moves as much as the measured entity, 2 = target entity moves half as far as the measured entity, and 0.5 = target entity moves twice as far as the measured entity.
  • Measurement Type MeasureType <choices>
    • What to measure. If Position, measures the entity's linear movement; if Eye Position, measures the entity's angular movement.


  • Kill
    • Removes this entity from the world.
  • KillHierarchy
    • Removes this entity and all its children from the world.
  • AddOutput <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire (-1 == infinite)>
    • Adds an entity I/O connection to this entity. Very dangerous, use with care
  • FireUser1
    • Causes this entity's OnUser1 output to be fired.
  • FireUser2
    • Causes this entity's OnUser2 output to be fired.
  • FireUser3
    • Causes this entity's OnUser3 output to be fired.
  • FireUser4
    • Causes this entity's OnUser4 output to be fired.
  • SetMeasureTarget <string>
    • Set the Entity to Measure, whose movement should be measured.
  • SetMeasureReference <string>
    • Set the Measure Reference entity.
  • Target <string>
    • Set the Entity to Move, which will be moved to mimic the measured entity.
  • SetTargetReference <string>
    • Set the Movement Reference entity.
  • SetTargetScale <float>
    • Set the scale to divide the measured movements by.
  • Enable
    • Enable the logic_measure_movement.
  • Disable
    • Disable the logic_measure_movement.


  • OnUser1
    • Fired in response to FireUser1 input.
  • OnUser2
    • Fired in response to FireUser2 input.
  • OnUser3
    • Fired in response to FireUser3 input.
  • OnUser4
    • Fired in response to FireUser4 input.

Additional Info

  • Useful for simulating motion outside of the hierarchy system.
