Phys thruster

Entity Description

An entity used to apply constant acceleration to a physics object. The force and torque is calculated using the position and direction of the thruster as an impulse. So moving those off the object's center will cause torque as well. Torque can be removed by unchecking the Apply Torque flag. The position of the thruster can be forced to be at the object's center by checking the Ignore Pos flag.

Keyvalues

Pitch Yaw Roll (Y Z X)
This entity's angular orientation in the world (also used for angular effect entities).
Defines the name that other entities refer to this entity by.
  • hammerid [Episode Two Update]
<integer readonly> This id is used for debugging purposes in Hammer.
  • attach1
<target_destination> Attached Object - Object to apply the force to.
  • forcetime
<float> Time of Force (0=inf) - Automatic shut-off after this time has passed. A value of 0 means to stay on forever or until deactivated.
  • force
<float> Force, in kg·in/s2. Will be integrated over time.

Flags

  • 1 : Start On
Thrust is on by default. (Will turn off after the time specified in forcetime.)
  • 2 : Apply Force
Apply linear force (if off, torque only)
  • 4 : Apply Torque
Apply rotational force (torque—if off, linear only)
  • 8 : Orient Locally
Maintain local relationship with the attached object
  • 16 : Ignore Mass
Impulse is independent of object's mass (impulse is acceleration, not force)
  • 32 : Ignore Pos

Inputs
