Event trigger

When you're designing a game event that either triggers itself or another event, it's really important to use the Event Trigger logic mechanic in your scene. This mechanic is essential for any triggering mechanisms you plan to include in your game.

In the horror game template, the Event Trigger is a component that consists of a trigger, condition groups, and an action list. Here's how it works: When the trigger is activated and the specified condition is met, the corresponding action is executed.

To make it simpler, think of it as a way to set up events in your game that happen automatically based on certain conditions being fulfilled. It's like creating a cause-and-effect relationship, where you specify what needs to happen for a specific action to occur.

Let's start with the most basic setup for this configuration.

Adding the Event Trigger component to your object

1. Select the object in the scene and view its properties by choosing the More icon.

2. In the Properties window, choose Add Event Trigger and you can continue to add the component. Or, you can choose Add Components and select the event trigger component.

   

   

3. After adding the Event Trigger component, you can edit its triggering mechanic in the Properties window. For more information about the component, see Event Trigger.

6. Customize the trigger's properties and settings following these steps:

   1. Drag the Trigger Zone object into the Trigger Object field.
   2. Choose OnTriggerZonePlayerEnter as the trigger event.

   4. Keep the delay at 0 for immediate action.

   These settings make the cube show the narrator when the player enters the trigger zone.
