TriggerSensorComponent is the condition container of the World Trigger system. It owns arrays of TriggerSensorType objects that define evaluation logic — collisions, interactions, record checks. When conditions pass, it fires WorldTriggerRequestBus::Trigger on the same entity.

For usage guides and setup examples, see The Basics: GS_Interaction.

Container Component

TriggerSensorComponent

Owns and evaluates all sensor type objects. Not subclassed — extended by adding TriggerSensorType objects to its arrays.

For usage guides and setup examples, see The Basics: GS_Interaction.

Overview

SensorType_Record is a TriggerSensorType that fires when a named save record is changed to a configured value. Add it to the andConditions or orConditions array on a TriggerSensorComponent.

Inherits from RecordKeeperNotificationBus — connects automatically on Activate and listens for record changes without polling. When a matching record change arrives, it calls TriggerSensorRequestBus::DoAction on the owning component, which runs the full condition evaluation pipeline.

The World Trigger system pairs a TriggerSensorComponent (condition side) with a WorldTriggerComponent (response side) to create event-driven world state changes. Each component owns an array of polymorphic type objects — sensor types define what conditions to evaluate, trigger types define what happens when the condition passes. Any combination of types can be composed on a single entity without scripting.

For usage guides and setup examples, see The Basics: GS_Interaction.

Breakdown

World Triggers split conditions from responses using a polymorphic type/component pattern. The two container components sit on the entity; logic lives in the type objects they own.

WorldTriggerComponent is the response container of the World Trigger system. It owns an array of WorldTriggerType objects that execute when triggered — toggling entities, setting records, changing stages, logging messages.

For usage guides and setup examples, see The Basics: GS_Interaction.

Container Component

WorldTriggerComponent

Owns and drives all trigger type objects. Not subclassed — extended by adding WorldTriggerType objects to triggerTypes.

Bus: WorldTriggerRequestBus (ById)

Field	Type	Description
`triggerTypes`	`vector<WorldTriggerType*>`	All types are executed on each trigger or reset event.

Method	Description
`Trigger()`	Calls `Execute(entityId)` on every type in `triggerTypes`.
`Reset()`	Calls `OnReset(entityId)` on every type in `triggerTypes`.

On Activate(), calls OnComponentActivate(entityId) on every type — use this for initial state seeding (e.g. entity visibility setup before any trigger fires).
