[<< wikibooks] Cross-Platform Game Programming with gameplay3d/Getting Started
== What is gameplay3d? ==
The gameplay3d project is an open-source, cross-platform, 3D framework that is aimed at supporting indie game developers who want to develop desktop and mobile games. The primary development language is C++, although Lua scripting is also supported.
A major motivation behind gameplay3d is to allow developers to make their games available on as many platforms as possible. It is platform-specific only where necessary, which maximises the possibility for code re-use across different platforms.
Gameplay3d is also designed to allow fast iterating and prototyping, which enables developers to realise and test ideas quickly and easily.

== Prequisites ==

=== Hardware ===
Your hardware will need to support:

OpenGL 3.2 (desktop); or
OpenGL ES 2.0 (mobile)

=== Knowledge ===
A strong grasp of C++ is required in order to use gameplay3d, as is an understanding of 3D graphics principles.
Some knowledge of the OpenGL API and the GLSL shader language is very helpful, although not strictly necessary to get started using gameplay3d.
Similarly, familiarity with Lua is helpful if one wishes to use gameplay3d's Lua scripting support (although use of Lua scripting is entirely optional).
Some useful links for learning about C++, 3D graphics, OpenGL and Lua can be found in Links to other useful resources.

== Using this book ==
If you are completely new to gameplay3d, we recommend that you begin by reading the first 4 chapters of this book (i.e. this chapter, An Overview of the Game Class, gameplay3d Design Concepts and Creating a Scene) to get an overview of how gameplay3d works. After that, feel free to skip around as required!

== Installation ==
Regardless of which platform you are using, you will first need to get hold of a copy of the gameplay3d repository, which is hosted at https://github.com/blackberry/GamePlay

=== Windows ===
The simplest way to clone the gameplay3d repository is to:

click on the "Download ZIP" icon on the gameplay3d GitHub page; and
extract the files to a folder of your choice.Alternatively, if you have git installed and want to take advantage of the version control features it offers, you can:

open git bash in a folder of your choice; and
run the command $ git clone https://github.com/blackberry/GamePlay.git.The second step is to install the external dependencies on which gameplay3d relies. This is done by running the install.bat script.
The dependencies which gameplay3d uses are as follows:

bullet - for physics
freetype2 - for font conversion
glew - for loading OpenGL extensions
lua - for scripting
oggvorbis - for compressed audio
openal - for positional audio
png - for image decompression
tinyxml2 - for XML parsing
zlib - for data decompressionThe third step is to make sure that you have Visual Studio Express 2013 for Windows Desktop installed, which is free to install and use.
After cloning the repository, installing the dependencies and installing VS2013, you are ready to open the gameplay solution (i.e. gameplay.sln). Before you run any of the samples for the first time, you will need to build the gameplay3d library, which in VS2013 can be done as follows:

Build > Build Solution (F7)

=== Mac ===
See how to install gameplay3d in mac from the internet. Let's google. It will be added here soon

=== Linux ===
This section demonstrates how to install gameplay3d on Ubuntu Linux.
First, make sure you have GIT installed. This can be done either through the Ubuntu Software Centre or by typing the following from the terminal:

Second, there are a number of other software packages that you need to have installed. To install these, type the following from the terminal:

This installs the following packages (to the extent that they are not already installed):

build-essential - this contains contains various required tools for compiling/building software from source
gcc - the GNU Compiler Collection
cmake - CMake, used for managing the build process
libglu1-mesa-dev - the OpenGL utility library development files; includes headers and static libraries for compiling programs with GLU
libogg-dev - Ogg bitstream library development files (used for compressed audio)
libopenal-dev - development files for the software implementation of the OpenAL (audio) API
gtk-2.0-dev - development files for the GTK+ library
curl - cURL, a command line tool for transferring data with URL syntax
libpcrecpp0:i386 - a C++ library of functions to support regular expressionsThird, if you haven't done so already, use git to clone the gameplay3d repository in your desired location.
Fourth, run the following command-line from the top-level directory of your gameplay3d repository, which installs the external dependencies listed in #Windows above:

This script requires curl.
Fifth, build the gameplay3d library by running the following from the top-level directory of your gameplay3d repository:

=== Blackberry ===

== Trying out the samples ==
Gameplay3d comes with a generous selection of samples. Between them, they demonstrate most of the concepts and classes found in gameplay3d. We strongly recommend that you familiarise yourself with all of the samples (particularly the "samples-browser" sample) and borrow/adapt the code in these samples in your own projects.

=== Windows ===
Right click the sample you want to run
Set as StartUp Project
Debug > Start Debugging (F5)

=== Mac ===

=== Linux ===
In order to run a sample (here the "sample-browser" sample is used as a demonstration), run the following from the top-level directory of your GamePlay repository:

=== Android ===

=== Blackberry ===

== Creating your first gameplay3d project ==

=== All platforms ===
To create a new cross-platform game project, run the script newproject from the repo root:

newproject.bat (on Windows)
newproject.sh (on Mac or Linux).The following is an example of running the newproject.bat script:

== Adding and running the new project ==

=== Windows ===
Add the Visual Studio project to the existing gameplay.sln solution;
Set the "gameplay" project as a dependency (right-click on the new project, click "Project Dependencies…", and select the "gameplay" project)
Build and run.

=== Mac ===

=== Linux ===
Open the terminal and navigate to the "build" folder contained inside your new project folder.Run the following commands:
Run the newly-created executable file, which will be found in [projectname]/build/bin/linux/.

=== Android ===

=== BlackBerry ===
