Current map as battle background error

[Acera]

Greetings,

I found this script for making the current map your battle background, (using the search function, yes it does work) but when I test it I get an error and my rather restricted knowledge with scripting is not really helping.
Here's the error;

line 21:
@battleback_sprite.tileset = RPG::Cache.tileset($game_map.tileset_name)

and here's the script;

    @viewport4.color = $game_screen.flash_color
    @viewport1.update
    @viewport2.update
    @viewport4.update
  end
end

If you're able to fix it could you please explain to me what was wrong and such (trying to learn RGSS, and for me examples always work the best)

Thanks in advance,

Is this VX or XP? This script is written for an XP maker game. "tileset_name" is no longer a property of Game_Map in VX, which would create an error like the one you are showing.

If you aren't however. I just plopped that script into a test project on XP and it worked without a problem. Are you using any other custom scripts? Where did you install the script?

Ugh I figured it out now... I get that error whenever I battle test via the database -.-. But I had to delete these lines

    
# If effect is showing
    if @spriteset.effect?
      return
    end

any idea what these do?

Thanks in advance,
