description	Implements factory and pool for RenderEventBase classes. Invoke when creating or managing render events that need object pooling for memory optimization.

Render Event Factory and Pool

Overview

This skill provides a comprehensive implementation of a factory and pool system for RenderEventBase classes, enabling efficient object reuse and memory optimization in game rendering systems.

Key Features

1. Factory Pattern: Creates instances of RenderEventBase subclasses through a centralized factory method
2. Object Pooling: Reuses event instances instead of creating new ones, reducing memory allocation and garbage collection
3. Automatic Registration: Automatically registers all RenderEventBase subclasses
4. Lifecycle Management: Handles event creation, initialization, and recycling

Implementation Steps

1. Modify RenderEvent Class

Add the following components to the RenderEvent class:

• Event Pool: A dictionary of stacks to store reusable event instances
• Event Types Registry: A dictionary to store event type information
• Factory Method: Create<T>() to create or retrieve events from the pool
• Registration Methods: RegisterEvent<T>() and RegisterAllEvents() to register event types
• Init Method: To initialize the factory and register all event types
• Return to Pool: ReturnToPool() to recycle event instances

2. Add Init Methods to Event Classes

For each RenderEventBase subclass, add an Init method that:

• Takes all public member variables as parameters
• Initializes the event's state
• Resets the IsDone flag to false

3. Replace Direct Instantiation

Replace all instances of new RenderEventBaseSubclass() with RenderEvent.Instance.Create<RenderEventBaseSubclass>() followed by a call to the Init method.

Usage Example

// Before
CameraMoveEvent cameraMoveEvent = new CameraMoveEvent()
{
    targetPosition = position,
    dialogStyle = UIDialog.DialogStyle.ClickPersonSay,
    content = "Hello World",
    person = somePerson
};
RenderEvent.Instance.Add(cameraMoveEvent);

// After
CameraMoveEvent cameraMoveEvent = RenderEvent.Instance.Create<CameraMoveEvent>();
cameraMoveEvent.Init(position, 0.5f, UIDialog.DialogStyle.ClickPersonSay, "Hello World", somePerson, null, null);
RenderEvent.Instance.Add(cameraMoveEvent);

Benefits

• Memory Optimization: Reduces memory allocation and garbage collection
• Performance Improvement: Faster event creation through object reuse
• Centralized Management: All event creation goes through a single factory
• Consistent Initialization: All events are initialized through standardized Init methods
• Scalability: Easy to add new event types without modifying the factory

When to Use

Invoke this skill when:

• You need to optimize memory usage in your game's rendering system
• You're creating multiple instances of render events
• You want to standardize event creation and initialization
• You're working with a system that generates many short-lived events

Best Practices

• Always use RenderEvent.Instance.Create<T>() instead of direct instantiation
• Always call Init() after creating an event instance
• Ensure all RenderEventBase subclasses have a properly implemented Init method
• Call RenderEvent.Instance.Init() during game initialization to register all event types
