Always Sensor: Blender 3D Game Engine



Logic Brick Index
Main index for actuators, controllers and sensors.
 

Always Sensor
When an Always Sensor is triggered, it sends one positive pulse to the attached controller.
 
  
 





  
1.  Always Sensor
When an Always Sensor is activated, it sends one positive pulse to the attached controller(s).
  • An Always Sensor is always active.  It is never deactivated.
  
2.  True Level Triggering
When a sensor is activated, it sends one positive pulse to the attached controller(s).  
  • True Level Triggering disabled:
Sends one positive pulse when the sensor is activated.
  • True Level Triggering enabled:
Continues to send positive pulses as long as the sensor is active.
  • Note:  The number of pulses sent is based on the logic tic rate.  Default is 60 times per second.
   
3.  False Level Triggering
When a sensor is deactivated, it sends one negative pulse to the controller.
  • Note:  An Always Sensor is always active.  It is never deactivated. 
   
4.  Trigger Delay
Skips sending pulses to the controller after the 1st pulse is sent
  • Skips the number entered.
  • Note:  Works with True Level and False Level Triggering
   
5.  Level
Part of the State System. 
  • When the State is activated, it checks to see if a mouse button or a keyboard key is pressed.  Sends a pulse to the controller if it is.
   
6.  Tap
When the sensor is activated, a positive pulse is immediately followed by a negative pulse (next frame).
  • True Level Trigger disabled:  Positive pulse becomes a positive pulse immediately followed by a negative pulse (next frame).
  • True Level Trigger enabled and Trigger Delay = 0:  No practical change.  Positive pulse is sent every frame.  Never has the chance to send a negative pulse.
  • True Level Trigger enabled and Trigger Delay greater than 0:  Each positive pulse becomes a positive pulse immediately followed by a negative pulse (next frame).
  • Note: False level triggering:  False level triggering is ignored when Tap is enabled.
   
7.  Inv
Inverts the output of the triggers. 
  • A positive trigger event sends a negative pulse to the controller.
  • A negative trigger event sends a positive pulse to the controller.
