XP Style Fog
XP Style Fog 1.0Shaz
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:
<fog name hue opacity blend_type zoom speed-x speed-y>
or via a Call Script command:
Code:
Call Script: $game_map.add_fog(name, hue, opacity, blend_type, zoom, speed_x, speed_y)
Change fog via a Call Script command:
Code:
Call Script: $game_map.start_fog_tone_change(red, green, blue, gray, duration)Call Script: $game_map.start_fog_opacity_change(opacity, duration)
