AllegroFlare

Current version - v0.8.8wip

AllegroFlare is a game programming library in C++. It's built on top of the Allegro 5 Game Programming Library, extending it with new features to make your game development expreience all the more enjoyable.

Build Instructions

AllegroFlare works on Windows, Linux, and OSX. Before compiling, you'll need to have Allegro 5.2.0 or greater on your system. If you're using gcc or clang, the process for building is the same on all systems.

Step 1: Clone the repo

$ git clone https://github.com/MarkOates/allegro_flare.git

Step 2: Set your directories in Makefile

At the top of the Makefile are 4 variables. Edit them to point to the locations where you have Allegro and AllegroFlare on your computer. If you're on Windows, your LIBS_ROOT might be something like C:/Users/Repos/.

LIBS_ROOT=/Users/markoates/Repos
ALLEGRO_DIR=$(LIBS_ROOT)/allegro5
ALLEGRO_LIB_DIR=$(LIBS_ROOT)/allegro5/build/lib
ALLEGROFLARE_DIR=$(LIBS_ROOT)/allegro_flare

Step 3: Run Make

$ make

Success! The only thing left to do is #include <allegro_flare/allegro_flare.h> in your program, and link with the AllegroFlare lib and the Allegro libs when compiling. Optionally, you can build the example programs with make examples.

If you run into any problems or have questions, ask on the allegro.cc forums.

Simple Example

#include <allegro_flare/allegro_flare.h>

class MyApp : public Screen
{
public:
    MyApp(Display *display) : Screen(display) {}
    void primary_timer_func() override
    {
        al_draw_filled_rectangle(300, 400, 200, 100, color::chartreuse);
    }
}

int main(int argc, char **argv)
{
    Framework::initialize(); // initialize all things AllegroFlare
    Display *display = Framework::create_display(800, 600); // creates a new Window
    MyApp *my_app = new MyApp(display); // creates a new instance of your app
    Framework::run_loop(); // run the AllegroFlare framework
}

Some Examples of Features and Tools

Framework

• Initialize (basically) everything with one function (Framework::initialize())
• Interface with the system through a parent class (Screen)
• Use virtual member functions to grab events (primary_timer_func(), mouse_axes_func(), joy_button_down_func(), key_char_func(), etc.)
• Get any asset by filename (Framework::bitmap("mypic.jpg"), Framework::font("Times.ttf 16"), etc.)

Resource Management

• Bins for media files (FontBin, SampleBin, BitmapBin)
• Use any image, sample, or font by filename

Graphics

• Easily position, size, rotate and draw images with (BitmapObject)
• Draw to offscreen bitmaps / Cache expensive renders (RenderCache)
• Use 3D models (Model3D)
• Use cameras for better placement/views (Camera2D, Camera3D)
• Use shaders (Shader)
• Easily place objects in 2D and 3D space (vec2d, vec3d, placement2d, placement3d)
• Modify images with filters (gaussian_blur(), color_overlay(), trim(), color_curve(), invert(), etc.)
• Generate images from data (draw_wav_sample(), draw_histogram(), create_gradient_bitmap(), etc.)
• Create paths (path2d)
• Create music notation (MusicNotation)

GUI

• Interface with the GUI through the parent class UIScreen
• Use from a list of usefull widgets UIButton, UICheckbox, UIDial, UIFramedWindow, UIImage, UIIntSpinner, UILabeledCheckbox, UIListSpinner, UIMusicNotation, UIPickingBuffer, UIProgressBar, UIScaledText, UIScreen, UIScrollArea, UIScrollBar, UISpinner, UIVerticalSlider, UIText, UITextArea, UITextBox, UITextInput, UITextList, UIToggleButton, UIXYController, UIWidget, UIWindow
• Easily create your own widget by inheriting from UIWidget

Motion

• timing and movement control (Motion)
• easing functions (interpolator::fastIn, interpolator::trippleSlowInOut, interpolator::bounceIn, etc.)

Scripting and Animation

• Use useful clases to automate playback of your objects (Motion, Timeline, Stage, Actor, Script)
• Use any member function from your classes in a script (Scriptable)
• Add attributes to your classes for scripting, saving, and loading (Attributes, ElementID)

Internationalization

• Support multiple languages with I18n

Color

• Color creation and manipulation (mix(), change_hue(), change_lightness(), etc.)
• Operators for ALLEGRO_COLORs (+, -, *, ==)
• Many color definitions (color::yellowgreen, color::blue, color::plum, color::floralwhite, etc.)

Encryption

• md5 and sha2 functions

Other cool stuff (requires dependencies)

• Interprocess and Shared Memory (boost)
• Text-to-speech API (windows)
• Download a file in a thread (curl)
• Webcam access (OpenCV)
• MIDI control (windows)

And More

• Bone trees, profiling timers, file path access, php-like functions, chainable media objects, etc.
