# BusTriggerEvent

> Talos 0.6 · Since 0.6

Payload of the engine-published `"trigger"` bus event: {@link TriggerEvent} plus both scene ids.

The ids are there because a subscriber is usually neither participant, and reading `.id` off a handle is only safe while that entity is alive. They are taken when the event is published and are `""` for an entity despawned in the same tick as the contact.

## Signature

```ts
export interface BusTriggerEvent extends TriggerEvent {
  volumeId: string
  otherId: string
}
```

Import: `import type { BusTriggerEvent } from "@argus/api"`
