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
-
Angles:
- Pitch Yaw Roll (Y Z X)
<angle> - This entity's angular orientation in the world.
-
Targetname:
- Name <string>
- The targetname other entities refer to this entity by.
- 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
Targetname:
-
Kill - Removes this entity from the world.
-
KillHierarchy - Removes this entity and all its children from the world.
-
AddOutput <string> - Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.
- Format:
<key> <value> - Format:
<output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite> -
FireUser1toFireUser4 - Fire the
OnUseroutputs; see User Inputs and Outputs.
- Activate
- Turn the force on
- Deactivate
