# Trap Mechanism

![This trap has two mechanisms: one for rotating the saw, the other for moving it along the slot.](/files/-MW54IrhTT5RZDmZwWX-)

These components define how the trap works: moving, rotating using physics or particles, and launching projectiles.

You can use multiple mechanisms in a single trap. Putting them together as parent-child will result in a more complex trap.

* **Play Mode:** After activation, the mechanism executes itself once only, or as a loop until the deactivation happens.
* **Cooldown:** Seconds before the mechanism can reactivate.  0 means no cooldown.
* **Reset on Finish:** This only available in Only Once play mode. 
* **Effects:** A list of rules that controls effects. Assign an [**Effect Handler**](/traps/effect-handlers/custom-effect-handler.md) to call a selected command on it when an Event happens.
* **Command:** what should the effect handler do when the selected event happens.
