Category:Sensor Brush Entities

From Valve Developer Community

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 invsible.
• 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 localised effects on entities in touch with the brush.
• Use the Template:sensor_brush to include entities in this category.
