XP Style Fog 1.0
Shaz​

Introduction
This is a simple port of XP's fog system.

Features
- Add fog via map notes or via a Call Script command
- Change fog tone and opacity via a Call Script command

How to Use
Paste script into a new slot below Materials. All methods are aliased, so this can go below other custom scripts.

Add fog to a map via map notes as follows:

                Code:       

1. <fog name hue opacity blend_type zoom speed-x speed-y>

复制代码

or via a Call Script command:
                Code:       

1. Call Script: $game_map.add_fog(name, hue, opacity, blend_type, zoom, speed_x, speed_y)

复制代码

Change fog via a Call Script command:
                Code:       

1. Call Script: $game_map.start_fog_tone_change(red, green, blue, gray, duration)Call Script: $game_map.start_fog_opacity_change(opacity, duration)
