Sensor Brush Entities use Brush geometry (rather than Studiomodel or Sprite geometry) to define a volume which is used to trigger events when an entity enters it.

  • Sensor brushes are generally NotSolid and invisible.
  • Sensors are passive: activated on touch, whereas switches and buttons require specific activation.
  • Some sensors are used simply to fire I/O events when triggered, whilst others have a specific localized effects on entities in touch with the brush.
  • Use the Template:sensor_brush to include entities in this category.
