FAQ

Final Project

• If you want to use GIF images, you can download the plugin algif.

  It can be used like videos after putting the library under your project folder.

• If you play multiple BGMs or sound effects at the same time, the al_play_sample could fail.

  You can either:

  1. Set RESERVED_SAMPLES to a higher value.
  2. Don't abort if al_play_sample fails.

• Unable to find resources when open the executable file located in ..bin directly.

  You can copy all used resources to the ..bin folder, since the executable file searches for the resources file located in the same folder.

• Error message: assertion failed .. bitmap_draw..

  A high chance is that you didn't initialize one of your image file before drawing it. e.g.

  The full error message:

• al_load_bitmap, load_resized_bitmap keeps failing, but I've done nothing wrong.

  Some image files you downloaded from the internet might be in the incorrect format. You can open it in PhotoShop, GIMP, Paint.NET, .. and re-save it as *.png or any format you want. This problem occurs sometime if you are using Chrome, but it doesn't occur if you use Firefox.

  For example: You can try to save this image: http://img1.3png.com/340af8a9dd2e666738f797b6573a963e1e8f.png. Although it says it's a PNG file, but it's actually a JPEG file. If you don't believe it, you can open it in Notepad, Notepad++, .. You'll see the JFIF at the beginning lines, if it's a PNG file, you should see NG.

• Task 1, 2, 3 are independent, you can test the game behavior after finishing each part.

• If your game lags (drop frames), you can comment out the line below:

• If your game loading time is very long, it is caused by the large music files. You can change the file to other audio, or simply disable (don't load) background music.

• Space key cannot be detected.

  You should change your input from Chinese to English, otherwise the keycode will be different.

Installation on Windows

Dev C 5.11 Install

• fopen is not safe .. in Visual Studio

  Download template again, or add #define _CRT_SECURE_NO_DEPRECATE at the top of your file.

• Visual Studio cannot compile

  When setting the configuration of Allegro5 plugins, make sure to set in All Configurations and All Platforms.

• File allegro-5.0.10-monolith-mt-debug.dll is missing in Code::Blocks

  Find the file allegro/bin/allegro-5.0.10-monolith-mt-debug.dll located inside the unzipped library folder.

  Copy it to your project folder under binDebug. If these folders don't exist, you can create them by yourself, or simply compile and run the code, your IDE will create them for you.

• task_2_ans.c compile error in Code::Blocks.

  Change

  to

• Header not found using the new version Allegro5.2 in Dev-C++

  fatal error: allegro5/allegro.h: No such file or directory

  The include and library paths assume that you have extracted the library using the built-in Extract All.., and put it into the C drive.

  A way to check if you had put them in the correct path is to see if the include path really exists in the file system.

• Cannot find resource files (when running task_2_ans.c)

  You should drag your files (pirulen.ttf, 32largebugs.jpg) into your project folder (same folder as your main.c or task_n_ans.c).

• Redefinition of ..

  You need to keep only one main function in one project, for example you may have both task_1_ans.c and task_2_ans.c in your project. You should only keep one.

  Or you might accidentally edit the Allgero5 library header, re-installing the library may help.

• When reopen the project, all settings are gone.

  For Code::Blocks you should open the *.cbp file.

  For Dev-C++ you should open the *.dev file. If all files disappear, use Project > Add To Project.. and select all files.

• On Code::Blocks Release mode: The Application was Unable to Start Correctly (0xc000007b)

  You should copy both allegro_monolith-5.2.dll and allegro-5.2.dll to your /Release folder.

• I want to hide the console window.

  For Code::Blocks:

  Set the build target type to GUI application.

  For other IDEs there are also such settings.

Installation on Mac OS

• There are OpenGL related bugs in newer version of XCode make sure to use XCode versions prior or equal to 10.3.

  Or you can use a custom Makefile.

• Command not found - brew

  When installing homebrew, it'll ask you to press Return to continue, you must press Enter and type your password to continue installing.

  If you press any other keys, it'll abort the installation process.

• Password are not read by terminal

  The password you type won't be shown on the terminal (it won't have something like ****). You can just type your password and press Enter.

• Cannot find resource files (when running task_2_ans.c)

  You should drag your files (pirulen.ttf, 32largebugs.jpg) into your project.

• Redefinition of ..

  You need to keep only one main function in one project, for example you may have both task_1_ans.c and task_2_ans.c in your project. You should only keep one.

  Or you might accidentally edit the Allgero5 library header (e.g. fmaths.inl), re-installing the library using the command below may help.

Allegro is a software library for video game development.^[2][3][4] The functionality of the library includes support for basic 2D graphics, image manipulation, text output, audio output, MIDI music, input and timers, as well as additional routines for fixed-point and floating-point matrix arithmetic, Unicode strings, file system access, file manipulation, data files, and 3D graphics. The library is written in the C programming language and designed to be used with C, C++, or Objective-C, with bindings available for Python, Lua, Scheme, D, Go, and other languages.^[5] Allegro comes with extensive documentation and many examples.

Allegro supports Windows, macOS, Unix-like systems, Android, and iOS, abstracting their application programming interfaces (APIs) into one portable interface. Previous versions up to 4.4 supported Windows, macOS, DOS, BeOS, and various Unix-like systems with (or without) the X Window System. There is also an independent port of Allegro on AmigaOS 4 and MorphOS.

'Antique gold is great for eyes that are green,' confirms Garnes. Since many green eyes have flecks of gold in them, using a gold shadow will brighten and bring out those hues for an ultra-flattering look. Mac colors for hazel green eyes pictures. So, if your eyes fall on the lighter side of the green-eyed spectrum, definitely experiment with gold shadows. 'I love to just do a wash of color on the lid and blend outward and top with lots of mascara for a serious wow!'

Released under the terms of the zlib license, Allegro is free and open source software.

History[edit]

Initially standing for Atari Low-Level Game Routines,^[6] Allegro was originally created by Shawn Hargreaves [pl] for the Atari ST in the early 1990s. However, Hargreaves abandoned the Atari version as he realized the platform was dying, and reimplemented his work for the Borland C++ and DJGPP compilers in 1995. Support for Borland C++ was dropped in version 2.0, and DJGPP was the only supported compiler. As DJGPP was a DOS compiler, all games which used Allegro therefore used DOS. Around 1998, Allegro branched out into several versions. A port to Windows, WinAllegro, was created, and also during this time, a Unix port of Allegro, XwinAllegro, was created. These various ports were brought together during the Allegro 3.9 WIP versions, with Allegro 4.0 being the first stable version of Allegro to support multiple platforms.

Allegro 5[edit]

Current development is focused on the Allegro 5 branch, a complete redesign of both the API and much of the library's internal operation. Effort was made to make the API more consistent and multi-thread safe. By default, the library is now hardware accelerated using OpenGL or DirectX rendering backends where appropriate. Many of the addons that existed as separate projects for Allegro 4 now interface seamlessly with Allegro proper and are bundled with the default installation. Allegro 5 is event driven.

Features[edit]

Allegro provides the following graphic functions:

• Vector drawing:
  • pixels, lines, rectangles, triangles, circles, ellipses, arcs, Bézier curves
  • shape fill, with or without pattern
  • polygons: flat, Gouraud, textured (3D) and translucent
• Sprites:
  • masked, compressed and compiled sprites
  • blitting, rotation, stretching, reduction, alpha blending, Gouraud shading
  • native support for BMP, LBM, PCX and TGA files (others supported with library extensions)
• Color palettes:
  • color palette manipulation (reading, writing, conversion)
  • conversion of color formats RGB <-> HSV
• Text:
  • support for different encodings and conversion, default is UTF-8
  • bitmap fonts (masking, colouring, alignment)
• Misc:
  • draw directly on the screen or on any-size memory bitmaps
  • hardware scrolling and triple buffering (where available), mode X split screen
  • animation functions for FLIC format^[7]

Addons[edit]

The community of Allegro users have contributed several library extensions to handle things like scrolling tile maps and import and export of various file formats (e.g. PNG, GIF, JPEG images, MPEG video, Ogg, MP3, IT, S3M, XM music, TTFfonts, and more).

Allegro 4.x and below can be used in conjunction with OpenGL by using the library AllegroGL which extends Allegro's functionality into OpenGL and therefore the hardware. Allegro 5 natively supports OpenGL.
