Parallax Background Script

Download the playable demo now:


.exe   Parallax_Background___R2.exe (Size: 1.17 MB / Downloads: 2)

This is the real R2 demo... I forgot to update this.

New Release #2 now available !

Known issues:
- Crashes on first message (in the demo):
You can download a working RGSS100J.DLL file from our download section and paste it over your one in windows\system32 -- You may have a corrupted DLL. This one has been proven to work with many script.

Infos:

This script will allow you to use the good old Parallax Background of RM2K and RM2K3 in RMXP. At the moment, only 4 directions are possible; up, down, left and right. But it's complicated to do the diagonals one (up-left, up-right, down-left and down-right).

I also used my first "Alias" method... neat stuff those alias. I'll be able to enhance all my past script with that, now that I know how it works...

Features:

- Move a panorama at the desired speed, in the desired direction.
- Fade in/out a panorama, even if moving.
- Fade Loop feature - Can make a panorama "blink".
- Stop Fade >> Can stop any fading anytime.
- Erase panoramas when you want to.
- Save parallax when you save a game (New in R2)
- Automatic parallax start upon map load ! (New in R2)

The script you need:

To use that script, simply add a page in your script editor (press INSERT) just above MAIN, and paste all that code in it.

(The instructions manual will follow, as usual.)

       ■ Map Parallax Background Settings:
       ---------------------------------------------------------------------------------------------------------
       ▼ DEFAULT PARALLAX SETTING FOR EACH MAP:
        
       The following list of lines defines each default parallax settings for each map using a
       parallax background. The number between square brackets is the map ID. Example:
       $map_parallax[3] will refer to the parallax settings of your map ID #3. Just copy the line
       to add more settings to all the maps using parallax. The rest will be done automatically by
       the script when you load a map in the game. This way you don't have to set full of code in
       your teleport, and you can save/load a game and it will work perfectly, as the script now
       save the parallax settings in the save file. The parallax settings and syntax is the same as in
       previous release: Parallax.new("name", direction, speed, opacity, hue)
       Read the manual and play the demo for more info and details about how to manipulate
       your parallax within the game. (It's the same way as before, but now you use the right
       map ID, so you would do $map_parallax[1].fade_out(2) to fade the parallax of map ID#2.)
