OnTrigger
OnTrigger
Event in Actor Class
Overview
The OnTrigger
event in the Actor
class is designed to respond to specific triggers activated for the actor, particularly those initiated by a TriggerNode
. This event plays a pivotal role in games where triggers influence character actions, gameplay mechanics, or narrative progression.
Description
- Event Type:
Action<string, bool>
- Functionality: This event is fired when a specific trigger, often set up via a
TriggerNode
, is activated for the actor. It receives a string identifier for the trigger and a boolean value representing the trigger's state. This design facilitates responsive actions to various triggered conditions.
Usage
The event is ideal for executing actions or logic in the game in response to trigger activations. This could include changing the actor’s behavior, initiating gameplay sequences, or advancing the storyline based on the nature of the trigger.
Subscribing to the Event
To effectively handle trigger events, subscribe a method with the signature Action<string, bool>
to the OnTrigger
event within a MonoBehaviour script. Unsubscribing from the event when it's no longer needed is crucial to maintain optimal game performance.
Example of Usage
public class TriggerResponseHandler : MonoBehaviour {
public Actor actor;
void Start() {
if (actor != null) {
actor.OnTrigger += OnSpecificTriggerActivated;
}
}
private void OnSpecificTriggerActivated(string triggerName, bool triggerState) {
Debug.Log($"Trigger '{triggerName}' activated for {actor.FullName} with state: {triggerState}");
// Custom logic to handle the activation of the trigger
}
void OnDestroy() {
if (actor != null) {
actor.OnTrigger -= OnSpecificTriggerActivated;
}
}
}
In this script, TriggerResponseHandler
is attached to a GameObject and subscribes to the OnTrigger
event of an Actor
. When a trigger is activated, possibly by a TriggerNode
, the OnSpecificTriggerActivated
method is called, allowing for appropriate responses to the trigger event.
Remarks
- The
OnTrigger
event is essential in creating dynamic and interactive gameplay experiences, allowing for conditional responses to specific game events. - Proper management of this event enhances the game’s interactivity and responsiveness, especially in scenarios where triggers dictate significant changes or actions.
- This event is particularly significant in games with complex mechanics or narrative-driven structures, where triggers set by
TriggerNodes
play a crucial role in driving gameplay and story elements.
