Angry Birds (Windows)

Angry Birds
Developer: Rovio Publisher: Rovio Platform: Windows Released internationally: January 4, 2011 This game has unused graphics. This game has unused music. This game has unused sounds. This game has debugging material.

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

Angry Birds is an award-winning strategy game for multiple platforms, but mostly known on iOS and Android. This article pertains to the PC version, which makes more sense to use on a laptop.

Mighty Eagle

To do: After edited scripts under PC Version can be used but unfortunately, 1.5.1-1.6.3.1 sprite feather, eagle button and eagle score text are missing.

The Mighty Eagle was a mobile-exclusive character, whose game mode could be purchased for a dollar. Even though the Mighty Eagle was exclusive to mobile devices, the graphics and sounds for it can be found. This suggests that this feature may have been planned at one point, although they could also be nothing more than leftovers.

First-Time Use Screen

This screen (found in "data\images\pc" of the game's directory) is what would've appeared when the player clicked on the Mighty Eagle icon (in the main menu, or the Power-Up Shop). The roll of film with the Mighty Eagle's eye led to this video.

Feathers and Unused Title

Notable in this sheet is what appears to be the original name for the PC version, "Angry Birds HD". However, the iPad version is called Angry Birds HD, so this may have also been a leftover from that.

(Source: iTunes Store Page)

It doesn't appear in v2.2.0. Found in MENU_ELEMENTS_2.png, (Not v2.2.0 PC) and MENU_SHEET_2.png.

The large feathers below it are the rankings that replace the stars when using the Mighty Eagle. For how much of the stage is destroyed by the Mighty Eagle, the black feather transitions to the colored feather by percentages. The small feathers on the right are for the menus. During level selection, the black feather is used for indicating a level with the Mighty Eagle used, which is under-layered by the colored feather, showing how much 'eagle score' is obtained.

Sardines

This can of sardines is how the Mighty Eagle gets summoned. Once the box is launched, it disappears and then the Mighty Eagle dives diagonally towards it, then bounces off the screen, destroying everything in its path. Any pigs are self-destructed if they survived.

Sprites

The Mighty Eagle entering and attacking once it appears. Note that these are supposed to be blurry, as they are blurry in-game.

Sounds

The Mighty Eagle bouncing once it hits the ground.

The cartoon sound effect that plays right after the Mighty Eagle makes its battle cry.

The Mighty Eagle's battle cry, which exists in two files: mightyeagle.wav and mighteagle.wav. The duplicate's existence appears to be a simple mistake.

Unused Store Image

This image's name is "SHOP_NEW_ME_BG.png", so it might've been used in the store.

Demo Level

There is an eagleDemo level in \data\levels. This might have been used as a power-up tutorial level in the mobile versions.

Funk Remix

This James Bond-esque remix of the title screen music can be found in the music directory with the name funky_theme.mp3. This can be legitimately obtained in the mobile versions by getting three stars on all the Mighty Hoax levels and finding the secret in the Angry Radio Golden Egg.

Title theme changes

In update 3.3.0, the game's main theme was replaced with Angry Birds Trilogy's main theme to celebrate the chapter "Red's Mighty Feathers", where Red finally gets a chapter-exclusive ability. Version 4.0.0 reverted back to the original track.

Versions 3.3.0 to 3.3.3 (Angry Birds Trilogy theme)	All other versions (Angry Birds theme)

Powerup Buttons

To do: Check for sprites for the slot machine and other powerup-related sprites.

Icons for the powerups from Angry Birds Friends (aka Angry Birds Facebook), which includes the shop images, as well as some placeholder graphics. They can be found in one file. Like the Mighty Eagle, these features never came to this version. There is also a lock button (iPhone retina Display) that is unused. That appears in BUTTONS_SHEET1

Old Level Complete

The sound used for when the player completes a level in the previous versions of Angry Birds. It was replaced with the ranking system from Angry Birds Rio, but the sound file still lays there as a leftover. It is only used when the player completes an episode.

Early Game Complete

The music was used in the oldest version where the player completes the game. This was replaced by the ranking system from Angry Birds Rio and like above, this song is still in the current version files.

Unused/leftover sprites

Crystal Button

Found in BUTTONS_SHEET_1.png (Or BUTTONS_SHEET_2.png), there is an icon for Chillingo (The original Publisher of Angry Birds on iPhone {under Clickgamer.com} & iPad)'s now dead Crystal SDK service, which was used in the iOS version where you could track scores via its leaderboard, get achievements, etc. It was shut down on June 23, 2013.

Fire Blocks

Unused blocks from a update that never came. There was also sprites for a Fire Bird and burning/charred pigs found ingame.

Unused Buttons

Among all the button icons, there are a lot of icons which were not used:

• The "Play" button has been replaced with a simple round button with a play icon.
• The left arrow button with a corner shadow might be intended for use in the level selection, but the one without the shadow was used.
• Some social media icons will only appear in the game if used the Chinese, Japanese or Korean localizations
• The ID card button icons were used only on the mobile versions, where you could save your progress online with a Rovio account.
• Ads never appear in the PC version. But in the mobile versions, you can purchase to remove ads. Hence, "Get the latest ad-free version!" button sprite was never used.
• Red tied with a ribbon, present in the iOS version as a button to share a free version of it.
• The crystal icon, again, but smaller.
• The trophy icon might have been for achievements, only present in iOS versions.
• The curved arrow icon and the curved arrow on 'level select' icon was never used in any versions. Might be intended as a return button.
• The blue button with hills will change the background to a static color, and will also remove all background images. This is only present in the mobile versions.

Intel Golden Egg Sprite

This golden egg sprite has the Intel logo engraved in it. An Intel-themed Angry Birds game was made for promotion, with some of the levels appearing in the Android version of Angry Birds Seasons. Maybe it was planned to appear on this game too. It is possible to view the levels themselves by either replacing already playable levels with them or by enabling it from editing the LUA game code files. There are 5 Intel Golden Egg levels in total. Here are the levels themselves:

Golden egg #12 soundbox

While the first five birds (Red, Blues, Chuck, Bomb, Matilda) and Hal were used, their 'hurt' sprites were never used. Same for Bomb's exploding phases, wide-mouthed Hal and Terence. This was added in v3.1.0.

Bad Piggies promotion

Sprite-sheet for the Bad Piggies promotion. This is supposed to be animated. This was added in v2.3.0.

Test arrow

To do: This is present in the level editor that isn't present in the PC version. The mobile versions (v7.1.0+) use this icon.

This pair of arrows were included in the birds and pigs' (INGAME_BIRDS_1) sprite-sheet, and are likely a leftover from the developer kit. It can be seen in this video.

Red's special (Mighty Feathers) activated

Red's sprite when he uses his ability. In Chapter 9, Red gets a special ability. While it does show up in the tutorial screen, this never shows up when used. This is also used in (INGAME_BIRDS_1).

Sticky Block

A rectangle bubble-like sprite and its particle sprites. Code of it present in older versions shows it was supposed to make objects bounce on it and make birds stick on it.

Unused blocks

Some weird block sprites are present in the blocks sprite-sheet that were never used in-game.

• The golden American football might have be used for golden egg #22 as it was a Super Bowl surprise. But, as this specific egg didn't used any sprite to seem invisible to players, this sprite was never used.
• Two different types of terrain, a wooden stage, and an ice rink.
• Two bent planks, each painted with a different color.
• A brass tray.
• A sideways metal pole that might be for a sideways flag.
• An ice platform. It was used in Angry Birds Seasons as a static platform.

• "Golden" sprites of the first 6 chapters' level complete items, and a King Pig for some reason. A golden item might be planned for each episode, but was scrapped for some reason.
• A puzzle piece. It was not used at all as it didn't fit with any chapter's theme.
• Also In Retina Display (Or iPad 3 & newer) (And v2.2.0 to v3.3.1), the Mighty Hoax block is supposed to be the Chrome sprites.

Rio golden egg

A sprite for a golden egg with a star, with the movie name Rio engraved on it. It appeared when you finish the golden egg #22 level, replacing the star. But, as the level complete screen was changed, this also got unused.

Debugging Functions

In the game's asset directories, there are Lua files for debugging the game, some debugging code is also present in pre-existing Lua scripts not titled as debugging features, these are shown by the game's build settings in options.lua.

Build Settings

To do: Show the effects of these in-game.

• showEditor: Shows the level and particle editors at the main menu, false is defaulted, due to files aren't present the game (until 7.1.0 which never released on PC before discontinuation), it crashes among toggling this setting while checking data/scripts/editor for editor.lua... maybe files are present in an older version (v1.0.0-v2.0.0) or the ones from current releases can be imported then this setting would be useful?

LUA error handler

Please elaborate. Having more detail is always a good thing.

In the game, There is a LUA error handler, Possibly for developing the game.

If a LUA is modified incorrectly or calls something that has or causes errors, the game will show an error about it, options are to ignore, abort or retry, If the file is too major that is having the problem, the game likely will force you to exit/crash unless the file is fixed. If the game memory is modified based on bird counts (?) the game will show the error below: Next bird not found! Please make sure all birds are correctly numbered for each level. Call stack: INFO...

Developer Cheats

To do: How do you enable the Developer Cheats?

If developer cheats are on, these can be used during gameplay.

FPS and memory display

A display on the bottom middle of the screen, for the FPS and memory in MB is visible, showFps is the internal flag name if using the Debug Console to enable.

Debug console

To do: Is there macros?

A giant overlay for both logging and entering text, covering the entire screen, called and hidden by by Shift-D it is possible to edit in-game flags and values for a session by using it, the same way for loading it on mobile releases (Right corner multi click) is also a method to load on the PC version. Using @ in your entry will close the debug console after it is entered. Also, using launchMightyBait() in your entry will use mighty eagle without purchasing and probably using bundleReward(?) in your entry will receive powerup reward, works on mobile too. Just replace "?" with number amount.

In-game

• C = Simulates a three star (or a 100% on Mighty Eagle) completion, ignoring the current score and using a predetermined score, the same way for using it on mobile releases (Left corner multi click) is also a method to load on the PC version.
• PgUp = Previous level.
• PgDown = Next level, ignores level lock restrictions.

Elsewhere

• Backspace-Q/W/E/R/T/Y/U = Crashes the game, it attempts to call powerups while the PC version doesn't enable them or have the files.
• Ctrl-Alt-# = "#" can be 1 (English), 2 (French), 3 (Italian), 4 (German), 5 (Spanish), 6 (Chinese), 7 (Taiwanese), 8 (Japanese), 9 (Portuguese) or 0 (Polish). Attempts to change the text locale, setting an unexisting locale other than Japanese or English crashes the game...
• S = Toggle sounds on or off.
• Ctrl-F5 = Attempts to create an Lua file containing the layout of a screen, crashes due to the folder layouts in the game data directory does not exist, manually creating it fixes the function to make a plaintext file.
• Shift-F12: Toggles mouse cursor visibility.
• Shift-C: Enables IAPs (doesn't work).
• Shift-Z: Powerup bundle reward (Crashes because powerups are disabled).
• Shift-X: Powerup slot machine (Crashes because powerups are disabled).
• F: Toggles visibility of the FPS and memory display.

Filesystem differences

In the current Angry Birds versions, scripts alone is only present, on PC and old versions, scripts and scripts_common are present, certain DRM files are only present on the PC version of the game, but are mentioned in current versions, LZMA packing is used after v6.0.1 but the PC version beyond v2.0.0 maintained 7z encryption for containing assets, WAVs, OGGs and MP3's are only supported. v1.0.0 used encrypted assets alone.
