• <Version 1.0c> 2012.01.20 - Fixed a bug where scrolling state icons would not dispose when showing a different actor in the same window
• <Version 1.0b> 2012.01.05 - Fixed a big bug where states were not showing up where they were supposed to be showing up in the battle scene
• <Version 1.0a> 2012.01.05 - Fixed a small bug where the opacity of the states corresponded to the incorrect value
• <Version 1.0> 2012.01.02 - Original Release

---

This script allows you to set it so that if an actor is afflicted with many states and buffs, it will scroll through them instead of only showing the first four.

• Allows you to show more than just four states and buffs if an actor is afflicted by more
• Can choose to either smoothly scroll or flash to the next icons
• Can precisely control the speed and how much time to pause on each icon

Paste this script into its own slot in the Script Editor, above Main and below Materials.

This script is plug & play and will show up in any window, but if you so desire, you can set the speed, pause time, and which windows this feature will be available. See the Editable Region beginning at line 28 for more details.

• ziifee; his RMVX script inspired this one

Please post in this topic at RMRK to report any errors or to ask any questions about this script.

Ha, I like this one. I'm gonna use it!
Thanks. The scrolling part is cool.

Is it just me or the icons in the main menu status don't scroll? They just appear, and disappear immediately.

No, they ought to scroll and they certainly shouldn't disappear; that sounds like a bug. Are they working in other scenes?

I would like to recreate the error, so what are your configuration settings and how many states and buffs are applied? You can simply copy and paste your version of the script.

Also, are you using any menu script?

Oh i managed to make it work, my problems was that i changed the opacity of the status_window in the main menu, so since your script makes the icons to match the opacity, they became invisible. That's why they disappeared. But after i deleted that line it worked perfectly.
Thanks for this nice script :D

EDIT: I found a bug, this time im sure it is. In battle, if my character gets 4+ buffs/debuffs, the icons start scrolling, but they change position on screen. Here is a screenshot (https://rmrk.net/proxy.php?request=http%3A%2F%2Fimg43.imageshack.us%2Fimg43%2F995%2Fbugky.jpg&hash=c52e9f5bf1b6139770750148b168f69d960e2770)

I'm using Yanfly's Battle Engine with several addons.

Alright, thanks. I will look into it.

Alright, I updated the script to v. 1.0b. It should fix the error you are receiving; just grab it from the first post and replace the one you have.

The script probably needs to be redesigned and rewritten as the code is kind of embarrassing at this point, but it should work at least.

It works now! Thanks a lot!

I found another little bug, concerning Yanfly's Battle Engine probably. The problem is, when selecting skills or targets, there is a little window on the right side of the screen, which shows the actor's face and states, that when any actor has 4+ states, just takes the scrolling icons of the actor that has more states even if its not his turn.
This is a screenshot to show what i mean:
(https://rmrk.net/proxy.php?request=http%3A%2F%2Fimg12.imageshack.us%2Fimg12%2F4709%2Fimmaginetog.jpg&hash=322b96ccb5747110280a3b8c82fbf9426a8731b8)
Now, this is the white haired girls turn, but the states displayed are not hers. Because she only had one buff when i took the screenshot.
This is YF battle engine for you to look at: http://yanflychannel.wordpress.com/rmvxa/battle-scripts/ace-battle-engine/ (http://yanflychannel.wordpress.com/rmvxa/battle-scripts/ace-battle-engine/)

Well, it's actually a logical problem solely on my end, unfortunately.

For now, try going to this part of the code, around line 210:

  alias masis_drwactoric_4jv3 draw_actor_icons
  def draw_actor_icons(actor, x, y, width = 96, *args)
    icons = (actor.state_icons + actor.buff_icons)
    # If icons exceed the space given and this window enables state scroll
    if (width / 24) < icons.size && @iconscroll_sprites


Replace it with:

  alias masis_drwactoric_4jv3 draw_actor_icons
  def draw_actor_icons(actor, x, y, width = 96, *args)
    icons = (actor.state_icons + actor.buff_icons)
    if @iconscroll_sprites
      @iconscroll_sprites.each_pair {|key, val|
        dispose_icon_scroll_sprites(key) if val.x == x && val.y == y }
    end
    # If icons exceed the space given and this window enables state scroll
    if (width / 24) < icons.size && @iconscroll_sprites


I might need to rewrite that script. I did it as a sprite since I did not want to be redrawing images onto contents every frame and because I wanted it not to interfere with things that might be drawn below it (as in that battle script you posted), but I think it causes more problems than it solves, especially in the realm of compatibility.

Ok, now it totally crashes, with an error like this: line 212 undefined method 'each_pair' for nil class

Sorry, I had put the wrong fix up before, but I fixed it a couple minutes before you just posted. Reverse the earlier change and make the one that I suggest in the post above.

It works perfectly now! Thanks a lot :D

Hey MA!

awesome script! one tiny problem though. im using Yanfly's Ace Battle Engine, and everything works great, but the scrolling only happens while commands/magic/attacks are executing, otherwise it is paused.

tried changing the script order, but nothing changed.

When I hide the window which contains the scroll icon, the window disappears, but the icon remains on the screen (though it stops being updated). Why is that? =(

Go to this part in the script:



  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  # * Update Icon Scroll Sprites
  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  def update_icon_scroll_sprites
    return unless @iconscroll_sprites
    @iconscroll_sprites.values.each {|sprite|
      sprite.update # Update each sprite
      # Match the opacity of the rest of the contents
      sprite.opacity = self.contents_opacity
    }
  end


Replace it with:



  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  # * Update Icon Scroll Sprites
  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  def update_icon_scroll_sprites
    return unless @iconscroll_sprites
    @iconscroll_sprites.values.each {|sprite|
      sprite.update # Update each sprite
      # Match the opacity of the rest of the contents
      sprite.visible = self.visible
      sprite.opacity = self.contents_opacity
    }
  end


One suggestion, should your ever plan to update the script again:
Include the option to hide multiples of the same icon.
Like, if 3 states with the same icon are applied, only display the icon once.
This way we could have multiple buff or debuff states, without clogging up the 4 icon window.
I would love that feature.
Sincerely

Love that feature, i suggest this is so cool to use it.

In case anyone else experiences the same issue I did...

I was getting a nil error from line 150 "can't convert nil into Array (TypeError)" and as I am not an expert at Ruby, I can't explain why. But I managed to figure out that after the first frame, where draw_bitmap combined the icons array with itself (to make the smooth rollover of the icons) the next frame was losing the ability to repeat it.

So, change that method to this, in order to fix the issue.

  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  # * Draw Bitmap
  #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  def draw_bitmap(icons, icon_hues = [])
    # Unless it is simply flashing through each row
    if MASIS_SCROLL_SETTINGS[:scroll_speed] != 0
      # Create a buffer so that it can smoothly scroll
      rollover = icons[0, viewport.rect.width / 24]
      icons += rollover if rollover
      icon_hues += icon_hues[0, viewport.rect.width / 24] unless icon_hues.empty?
    end
    # Draw all icons
    icons.each_with_index {|n, i|
      if icon_hues.size > 0 # Icon Hue Compatibility
        draw_icon_with_hue(n, icon_hues.shift, i*24, 0)
      else
        draw_icon(n, i*24, 0)
      end
    }
  end



Also note that icon_hues may also suffer from the same issue if its ever not empty. Having not run into a problem, I have left it alone.

I apologize if I am mistaken the actual issue. Just hoping to help. ;)
