Adjust Saturation

[Grathea]

Basically, what I need is a script that will adjust the saturation of the screen by a value. However, I would prefer that certain events be taggable as to not be effected by this.
I was looking earlier, and stumbled over a method in the MACL that adjust saturation. However, if anyone can adjust this to fit my one requirement, I'd love it.

If it's too difficult, let me know. This is extremely important to my game though, so I'd hate not to have it. I can work out alternate methods, but that would boost filesize hugely, and I don't really want to do that.

As an added incentive, if you make this for me, I'll do some spriting for you! Charsets or tilesets, your choice.

do you mean the stauration of a color object?
or do you mean the tone?

Setting the "gray" value of the color tone will adjust its saturation, which is probably what you mean:

# Half saturation=128, desaturated=255
$game_screen.start_tone_change(Tone.new(0,0,0,128), 20)

However, I don't believe it's possible to disable this effect for specific sprites, because the character sprites are interwoven with the tilemap--they have different Z values as well as the tilemap itself.

My thought on this now is placing the tagged sprites into a separate Viewport object which works. But you will get weird z issues that I can't really get around. It seems the viewport has precedence over the z. So I finally decided on moving every sprite into the new viewport. And playing with the update loop by adding a conditional to adjust tone based on whether or not the sprite is tagged. This does work but adds a little extra overhead to the drawing of Spriteset_Map as it includes a conditional check within a for loop but also adjusts the tone of the sprite if it isn't tagged.

Just create an empty section above main and paste in this code. At the top of the Spriteset_Map is a section called Constant Variables. Just below it is "Ignore_Tone_Tag = '_itone'". You can adjust the string to however you want event names to be tagged. Make sure its unique though. An event name like "Woah_itone" works that same as "_itoneyurobbie".

THANK YOU SO MUCH, khmp. If you want anything sprited, whenever, just PM me with details. This script is probably the single most important thing to my current mini-project.
