# triggers

A list of prims that execute a behavior’s actions.

## Discussion

The runtime executes all actions in the [actions](/documentation/USD/actions) array if the conditions of any trigger in [triggers](/documentation/USD/triggers) are satisfied. Only insert [Preliminary_Trigger](/documentation/USD/preliminary-trigger) prims in this array.

### Declaration

```other
rel triggers
```
