照明効果を適用するプラグイン – RS_SimpleLight.js

===============================================================
Introduction
===============================================================
This plugin implements a dynamic lighting/lantern effect using WebGL shaders.
The light follows the player character and illuminates the surrounding area,
creating an immersive atmosphere for dark dungeons, night scenes, or horror games.

===============================================================
Performance Considerations
===============================================================
Since this plugin uses shader-based lighting effects rather than image-based solutions,
it may cause performance issues on less powerful devices like mobile phones.
Consider this when implementing it in your game, especially if targeting mobile platforms.

===============================================================
Plugin Commands
===============================================================
Unlike many lighting plugins that provide complex command systems, RS_SimpleLight
focuses on simplicity with just two essential commands:

1. To enable the lighting effect:
RS_SimpleLight Enable

2. To disable the lighting effect:
RS_SimpleLight Disable

===============================================================
Technical Details
===============================================================
This plugin creates a lighting effect using PIXI.js filters and custom GLSL shaders.
The light follows the player and adjusts based on the player's direction.

Key features:
- The light intensity and size are configurable
- The light automatically adjusts to the player's position and direction
- Light color can be customized through code (using the setColorTone method)
- Works with RPG Maker MV's save/load system

===============================================================
Advanced Usage (For Developers)
===============================================================
For advanced users who want to modify the light properties programmatically:

1. Change light size (smaller values = larger light):
$gameSystem.setLightProperty('size', 1.0); Value between 0.001 and 1.0

2. Change light color (using code):
Access the filter in the active spriteset
var filter = SceneManager._scene._spriteset._simpleLightFilter;
if (filter) {
Set to default white color
filter.setDefaultColorTone();
OR set to red color
filter.setRedColorTone();
OR set to custom RGB color (values from 0-255)
filter.setColorTone(255, 255, 0); Yellow light
}

===============================================================
Compatibility Notes
===============================================================
- This plugin is compatible with RPG Maker MV v1.6.1 and above
- May conflict with other plugins that modify the filter system or rendering
- Works with the core save/load functionality without issues (since v1.1.01)

===============================================================
Examples & Use Cases
===============================================================
- Create a dark dungeon where the player must navigate with limited visibility
- Implement day/night cycles by enabling/disabling the light based on time
- Create horror scenes with limited vision to increase tension
- Use colored lights for special effects (red for danger, blue for ice areas)
