Need a little help with my script, Can't access some attributes :/ Options

[Sel Feena]

Hello all, I've started developing a photo script. Right now it's just script calls, with windows and scenes to come later.

However, I've hit a snag and am tearing my hair out trying to figure out how to get access to two attributes:

The name of the current map, that can be set in the game editor
The name of an event, that can be set in the game editor

This info will be referred to in the initialize function for SelFeenaPhoto

Here's my code so far...

CODE

=begin

##############################
## Basic Photo System V 1.0 ##
##############################

Author : Sel Feena
Date   : -.06.11

A simple system that lets your party keep a collection of
screenshots, which are stored along with descriptive data.
The data stored is:

* The snapshot itself (obviously), which is a Bitmap object.
* The ID of the map the photo was taken on.
* The player's XY coords and what direction they were facing.
* The top left XY coords of the photo.
* Information about any events that are captured in the photo:
  -The event's ID
  -The event's XY coords
  -The values for the event's Self-Switches

Compatibility
-------------

Adds new functions to the Game_Party class, and changes its
initialize function. Should be fine.

Possible Bugs
-------------

It doesn't seem possible in the editor, but using maps in your game that are
smaller than 17 X 13 in size could mess things up.

################
## How To Use ##
################

Create Photo
------------

To create a photo, use the following script call:

myPhoto = SelFeenaPhoto.new

Add Photo to Collection
-----------------------

To add the photo to your collection, you'd then type:

$game_party.addPhoto(myPhoto)

The new photo will be added to your party's collection. HOWEVER, if your
collection is full then the photo in slot 0 will be erased to make room.
Set the maximum number of photos allowed in the module below.

Get Photo from Collection
-------------------------

To get a photo, call:

myPhoto = $game_party.getPhoto( x )

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0

Remove Photo from Collection
----------------------------

To destroy a photo, call:

$game_party.delPhoto( x )

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0

Get Number of Photos in Collection
----------------------------------

Use this script:

collection_size = $game_party.getPhotoCount

Make good use of this function call to avoid out-of-bounds errors!

Get Photo Image
---------------

myPhoto = $game_party.getPhoto( x )
picture = myPhoto.getImage

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0
This function returns a Bitmap object.

Get Location of Photo
---------------------

myPhoto = $game_party.getPhoto( x )
location = myPhoto.getLocationID

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0
Variable 'location' will then have the Map ID of where the photo was taken.

Get Player's Position when Taking Photo
---------------------------------------

myPhoto = $game_party.getPhoto( x )
player_loc_data = myPhoto.getPlayerPosition

player_x = player_loc_data[0]
player_y = player_loc_data[1]
player_dir = player_loc_data[2]

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0
This function returns an array of three integers:
   - The player's X position.
   - The player's Y position.
   - The direction the player was facing:
      - 2 -> Down
      - 4 -> Left
      - 6 -> Right
      - 8 -> Up

Get Photo's Position
--------------------

myPhoto = $game_party.getPhoto( x )
photo_loc_data = myPhoto.getPhotoPosition

photo_x = photo_loc_data[0]
photo_y = photo_loc_data[1]

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0
This function returns an array of two integers:
   - The photo's top-left X position.
   - The photo's top-left Y position.

Get Number of Events in Photo
-----------------------------

myPhoto = $game_party.getPhoto( x )
events_in_photo = myPhoto.getEventCount

Where x is the index of the photo in the collection. Just like
arrays, this starts from 0

Is a Certain Event in Photo?
---------------------------

myPhoto = $game_party.getPhoto( x )
has_event = myPhoto.hasEventWithID( i )

Where x is the index of the photo in the collection, and i is the ID
number you're looking for.
Returns true or false.

For the name of the current map, this should work

CODE

class Game_Map
  attr_reader :name
  alias :mapname_setup :setup
  def setup(map_id)
    mapname_setup(map_id)
    data = load_data("Data/MapInfos.rvdata")
    @name = data[map_id].name
  end
end

To get the name, just write $game_map.name

For the event name, I think Night_Runner made one. I'll search around a bit.

EDIT: Nevermind, that was for XP. However, I found a solution.

CODE

class Game_Event
  attr_accessor :event
end

Insert that somewhere in the scripts (I put it under the other script I gave you), and then use
$game_map.events[Event_ID].event.name to get the name.

Bah. Kind of lame that you can't get to them without rewriting code. Silly VX :/

Thanks for the help.

While I'm here, and to avoid clogging up the help forum, can someone tell me how to access the Arrows in the game system's windowskin file, if that's even possible? So, my windowskin right now is (from CLOSET-VX):



And I want to be able to display the brown up/down/left/right arrows in a window.

The only way I know on how to get them is to have the contents bitmap to be bigger than the actual window. I'm sure it's possible, but I don't know how. Not simple anyway. One solution I know is that you can open the windowskin file and then cut out the parts needed through a script. I don't know how to do that though.. Sorry.
