# Raycast Triggers

![](/files/-MW9SIioiRbFOet4ekI-)

Use this trigger type for detector rays. Note that this is a trigger behavior only, for visualizing the laser beam you need a Ray Handler too. 

* **Trap:** the trap this detector ray controls. 
* **Action:** Activate, Deactivate or Toggle. (For Toggle you always need to specify a trap)
* **Cooldown:** time (seconds) until the trigger can react to events again.
* **Max Distance:** how far the ray (laser) should extend. 
* **Layer Mask:** use these to include or exclude objects from raycasting.
* **Tag Filter:** the trigger reacts when the raycast hits a game object with these tags.
* **Events:** you can set Unity Functions on specific events, for example, play audio, particle effect, or animation.
