Change battleback during battle

[Kes]

I've tried the usual Change Battleback command, and that didn't work.
Can this be done using event commands or will I need a snippet?

Thanks.

 

[Andar]

yes and no

the event command changes the setting for the map, that is why it doesn't work during battle.
However I once read a post here that there is a script command to force the battlescreen to update the battleback at any time from the then-current map setting.

So that way you'll need both - the event command to set the new battleback and the script command to force the update.

Unfortunately I don't remember the script command myself, but someone around here should be able to find the old post for it...

Searched. Found an Archeia post. I'll quote it:

Feb 12, 2014
There is a way. In troops tab:

Change Battleback to your desired graphic.

Script Call: SceneManager.scene.refresh_battleback

This will only work if you play in-game from Map -> Battle and not in test play.

Might as well try this?

@Faye Valentine Thank you very much for this. I'll test it as soon as I get home this evening.

Refresh battleback doesn't exist. Try this instead (which again, I'm too lazy to test)

spriteset = SceneManager.scene.instance_variable_get("@spriteset")
spriteset.dispose_battleback1
spriteset.dispose_battleback2
spriteset.create_battleback1
spriteset.create_battleback2

@TheoAllen: tested, it's not working. Tested under standard parameters (blank project)

Archeia script is working. Tested. Only in-game, though. Game crash on troops testing.

@TheoAllen and @Faye Valentine
I tried both ways.
With Archeia's method I got a crash with the error message
undefine method 'refresh battleback'

With TheoAllen's code in the script call, however, it worked like a charm.

Thank you both very much for your help with this.
I shall keep the thread open for a little while in case some oddity creeps out of the woodwork, but I'm hopeful that all will now be well.

 

[Faye Valentine]

@Kes: wow funny thing. I tested it in a blank project, but straight on the game and it showed no crash message whereas theo's crashed, both in-game and on troops tab. Well, glad you found a working solution, mate.

 

[TheoAllen]

@Faye Valentine I was going to reply u that I don't believe, but it's Kes that has the problem so I shrugged in the end.
What was the crash though? Those are really default script function, while "refresh_battleback" was never in default script.
It's funny it's working in your side actually.

Using @TheoAllen 's code I got a script to work.

Spoiler: Change Battleback by Spell

# Change Battle background with a spell
# Created by Roninator2
# Version 1.0
# free for commercial use

# How to use
# Name the graphic files whatever name you specify in the Filename below
# and numbered, with the second battleback with an a at the end.
# e.g.
# SpellBG1.png <- battleback 1
# SpellBG1a.png <- battleback 2
# SpellBG2.png <- battleback 1
# SpellBG2a.png <- battleback 2
# SpellBG3.png <- battleback 1
# SpellBG3a.png <- battleback 2

# files must be present even if they are empty
# then have the spell with the notetag <change_bbg: 1>

# it does not restore the original battleback if no battleback is
# setup before the battle starts. *You get the swirl image of the map.

module R2_change_bbg_by_skill
  Regex = /<change_bbg:[ ](\d+)>/i
  Filename = "SpellBG"
end

class Scene_Battle < Scene_Base
  alias r2_use_item_skill_bg    use_item
  def use_item
    r2_use_item_skill_bg
    item = @subject.current_action.item
    @setbg = false
    if item.is_a?(RPG::Skill) && item.note.split(/[\r\n]+/).each { |line|
      case line
      when R2_change_bbg_by_skill::Regex
        @bgnum = $1.to_i
        @setbg = true
      end
      }
    end
    if @original_bg1 == nil
      @original_bg1 = $game_map.battleback1_name
      @original_bg2 = $game_map.battleback2_name
    end
    if @setbg == true
      bbgimage = R2_change_bbg_by_skill::Filename.to_s
      spellbg1 = bbgimage.to_s + @bgnum.to_s
      spellbg2 = bbgimage.to_s + @bgnum.to_s + "a"
      Graphics.freeze
      $game_map.change_battleback(spellbg1, spellbg2)
      spriteset = SceneManager.scene.instance_variable_get("@spriteset")
      spriteset.dispose_battleback1
      spriteset.dispose_battleback2
      spriteset.create_battleback1
      spriteset.create_battleback2
      Graphics.transition(60)
    end
  end
  alias r2_terminate_bg   terminate
  def terminate
    r2_terminate_bg
    $game_map.change_battleback(@original_bg1, @original_bg2)
    @original_bg1 = nil
  end
end

Neither of your codes works.

The Archeia code says "refresh_battleback" is undefined. For Theo's code, "instance_variable_get" is undefined.

Are you using plugins to do this?

 

[TheoAllen]

@Knight9910 without more information, I'm guessing you're using either MV or MZ. This was for none of them. It is for RPG Maker VXAce.
