Installation

To install wmwpy, run

pip install wmwpy

or

python -m pip install wmwpy

You can also install it from the source, which may be needed because it is frequently being updated, although you need to make sure git is installed.

pip install wmwpy@git+https://github.com/wmw-modding/wmwpy

Usage

Get game folder

To get started, you need to have a Where's My Water? game folder, either an extracted apk, ipa, or on a rooted / jailbroken device (for editing the game files directly). The game must be extracted like this.

- root
 - assets
  - ...

The assets folder can be specified in wmwpy.

Loading the game

Start by loading the game inside wmwpy

import wmwpy
game = wmwpy.load('game/wmw')

You can specify the assets folder

game = wmwpy.load('game/wmw', assets = '/assets')

You can set assets = '.' if you have the gamepath (first parameter) set to the assets folder (such as on a rooted / jailbroken device).

Alternately, you can specify the platform.

game = wmwpy.load('game/wmw', platform = 'android')

This automatically sets the assets folder to what it is on the platform.

Platform	assets folder
android	/assets
ios	/Content

You can also specify the game, which sets things up for that game.

game = wmwpy.load('game/wmp', game = 'WMP')

Currently all the games are

Game	Code
Where's My Water?	'WMW'
Where's My Water? Free	'WMWF'
Where's My Perry?	'WMP'
Where's My Perry? Free	'WMPF'
Where's My Mickey?	'WMM'
Where's My Mickey? XL	'WMMXL'
Where's My Mickey? Free	'WMMF'
Where's My XiYangYang?	'WMXYY'
Where's My Water? Featuring XiYangYang	'WMWFXYY'
Where's My Water? 2	'WMW2'
Where's My Holiday?	'WMH'
Where's My Valentine?	'WMV'
Where's My Summer?	'WMS'

You can also specify the base assets path, the folder within the assets folder that contains all the assets. For example, Where's My Perry? has all the data within /assets/Perry.

game = wmwpy.load('game/wmp', baseassets = '/Perry')

Each game has the database in a different location, so you can specify it.

game = wmwpy.load('game/wmp', db = '/Perry/Data/perry.db')

Since Where's My Water? 2 uses a profile instead of a database for the save data, you can also specify that.

game = wmwpy.load('game/wmw2', profile = '/Water/Data/factory_profile.json')

You can also provide a function to be called during the loading, so you can keep track of the current progress, e.g. in a gui application with a progress bar.

game = wmwpy.load('game/wmw', load_hook = lambda progress, text, max : print(f'({progress}/{max}) {text}'))

The inputs for the function are

(
   progress : int,
   text : str,
   max : int,
)

Once you're done editing all the files, you need to dump the all the assets.

game.dump()

This will save all the files in the game inside the assets folder. You can customize this if you want them saved in a different location.

game.dump(folder = 'path/to/output')

Main classes

Level

To load a level from within a game, use the .Level() method.

level = game.Level('first_dig')

The first input can be the name of a level inside the /Levels folder (first_dig), an absolute path to the level (/Levels/first_dig), or the path to an xml file (/Levels/first_dig.xml).

You can also specify the xml and image separately.

level = game.Level(xmlPath = '/Levels/first_dig.xml', imagePath = '/Levels/first_dig.png')

Some levels include objects that wmwpy fails to load, so you can use the ignore_errors parameter to ignore them.

level = game.Level('first_dig', ignore_errors = True)

You can also use the HD or TabHD textures for the objects.

level = game.Level('first_dig', HD = True, TabHD = True)

If both are specified, TabHD will get priority. If it can't load TabHD textures. See hierarchy.

- TabHD
 - HD
  - Low Quality

You can also provide a function to run while loading to see the current progress.

level = game.Level('first_dig', load_callback = lambda progress, text, max : print(f'({progress}/{max}) {text}'))

The inputs for the function are

(
   progress : int,
   text : str,
   max : int,
)

The objects in the level are all accessible in a list

>> level.objects
[
   <wmwpy.classes.object.Object object at 0x000001C7627FE850>,
   ...
]

See Object

The level properties are also accessible as a dictionary

>> level.properties
{'HeavyIntro': '1'}

WMW2 challenges are also accessible in a list

>> level.challenges
[<wmwpy.classes.level.Level.Challenge object at 0x000001C72176ADD0>]

Once you're finished editing the level, you can get the xml.

xml = level.export(filename = '/Levels/first_dig.xml',)

This returns the xml file as bytes, but also saves the file to the game filesystem.

Challenges

Each challenge has requirements in a dictionary

>> level.challenges[0].requirements
{
    'WinWait': {
        'seconds': ''
    },
    'Duck': {
        'count': '2'
    }
}

Object

To load an object within a game, use the .Object() method.

obj = game.Object('/Objects/broken_pipe.hs')

You can also use the HD or TabHD textures for the objects.

level = game.Level('first_dig', HD = True, TabHD = True)

If both are specified, TabHD will get priority. If it can't load TabHD textures. See hierarchy.

- TabHD
 - HD
  - Low Quality

An object has many properties

>> obj.properties
{
    'Type' : 'spout',
    'SpoutType' : 'DrainSpout',
    'Goal' : '1',
    'GoalPreset', : 'Swampy',
}

An object also has many Sprites

>> obj.sprites
[<wmwpy.classes.sprite.Sprite object>]

The object image is a PIL image.

>> obj.image
<PIL.Image.Image image mode=RGBA size=300x300>

The image scale can be set

obj.scale = 20

You can also save a GIF of the object animations

obj.saveGIF('broken_pipe.gif')

Once you're finished editing the object, you can get the xml.

xml = export('/Objects/broken_pipe.hs',)

This returns the xml file as bytes, but also saves the file to the game filesystem.

Building package

To build the package, install build

pip install build

Then run

py -m build

Building docs

To build the docs, make sure sphinx is installed

pip install -r doc-build/requirements.txt

You then need to run

sphinx-build -b html doc-build docs

• Thanks to Mark Setchell for helping to make loading waltex images faster (still need rgb565 and rgba5551).
