Panorama change based on variables

[sixtyandaquarter]

Hello peoples, how is your collective day going?
It should be obvious by the topic icon that I am looking for a script for VX.  Just figured I'd throw that out incase someone didn't notice, I wouldn't want you wasting your time.  What I am requesting is as follows:

A script that will change the panorama of maps depending on a set variable.  Only certain maps will be altered, and they won't all be altered to the same thing, so the script must be able to handle this.

Basically when a variable is increased, the panorama for that map would change.  Another map would have different panoramas, and have different numbers needed for this to take affect, but would work off the same variable.

Possibly, this could be set up so that each map ID can be given a set.
Map ID 1 could have a {1 => 2, 5 => 3, 6 => 4}
Where when the variable is 1, it becomes 2.png, and when the variable is 5 it becomes 3.png, and at 6 becomes 4 png, see where I'm going with that?
Simultaneously,
Map ID 2 could have a {1 => 12, 13 => 13, 29 => 14}
Where at variable 1, the panorama is 12, etc.

Now I don't know if the above would work, having it be 2.png or what, I just thought it might?  Although if there is a better or easier way for anyone who would want to take up this request, by all means go with whatever is easier.

Also if I typed this horribly and am not clear, by all means inform me.

Thanks.

I can do that for you. That's really easy to do. :thumb:

  def variable_to_parallax(variable_id)
    map_id = $game_map.map_id
    value = $game_variables[variable_id]
    return unless Parallax::Parallaxes.has_key?(map_id)
    if Parallax::Parallaxes[map_id][value].nil?
      $game_map.parallax_name = Parallax::Parallaxes.default
    else
      $game_map.parallax_name = Parallax::Parallaxes[map_id][value]
    end
  end
end

I can also add different looping/scrolling based the the variable's value if you want.
It works as you said, Map_ID => {variable_value => parallax_name}

Hope you like it!

Just ran a the test, and that's absolutely perfect, Dargor.  Thanks

I personally don't need looping or scrolling based on variables for what I'm doing, but I can certainly see lots of uses for it both aesthetically and practically.

Thanks again for taking the time to help out
