Critical Hit Game Engine

C++ game engine built using OpenGL and SFML and available under a permissive licence.

#Build Instructions

Use premake4 to generate a project file or Makefile and build with your OS-specific tool. We also use Python 3 for some support scripts.

##Windows

Install Visual Studio Community 2013.

Download Premake 4.3 and extract premake4.exe to C:\premake4\bin.

Add C:\premake4\bin to your PATH user environment variable:

1. Type "environment variables" into the Start Menu search menu to access Environment Variables.
2. If Path already exists in User variables, edit it and add "C:\premake4\bin;" to the front. If Path doesn't exist, create a new variable with "Path" for the name and "C:\premake4\bin" for the value.

Install Python 3.0+ and add "C:\PythonXX" to your PATH user environment variable (see above).

OpenGL is statically linked in Visual Studio and SFML is statically linked in the project source, so installing them separately is not required.

Generate the Visual Studio Project and run the build:

1. Open a command prompt and navigate to the directory containing premake4.lua.
2. Type premake4 vs2010. Visual Studio 2010 project files will be generated.
3. Open the .sln file in Visual Studio 2013. You should be prompted to upgrade the projects to the VS2013 compiler and libraries. Click OK. If you do not see this dialog, you can force it to appear with Project>Retarget Solution.
4. Set the Solution Platforms dropdown to x64.
5. Right-click the Solution in the Solution Explorer and click Build Solution.

##Mac OSX

###Libraries

We highly recommend using Homebrew when developing on Mac OSX. If this is not possible, you can download the required libraries and edit the PATH manually.

####Homebrew

Open a terminal and type brew install premake sfml

####Manual Download

If Homebrew is not available, you can manually download add the binary to your path.

Download Premake 4.3 and extract the binary from the tarball. Move this binary to /opt/premake4/bin.

Open ~/.bash_profile with a text editor and add a line to edit your PATH. For example:

PATH="/opt/premake4/bin:$PATH"

You will have to log out and in again to apply this change.

You will then have to install SFML. See SFML's Download page for more information.

###Python Python3 may already be installed. You can check with python3 --version. If it is not installed you can install it using Homebrew or download it from here.

###Build Tool

You can use either of two options to develop and build: XCode or the command line with GNU Make.

####XCode

Install XCode from the App Store.

Open a terminal and navigate to the directory containing premake4.lua. Type premake4 xcode3. An XCode project file will be generated. Open it with XCode and run the build.

####GNU Make

Install the Command Line Tools from developer.apple.com (Apple Developer account required).

Open a terminal and navigate to the directory containing premake4.lua. Type premake4 gmake. A Makefile will be generated. Type make help for usage information, or simply make to run the default debug build.

##Linux

Use your distribution's package manager to install the build dependencies:

• GCC or Clang
• Make
• Premake >= 4.3
• SFML 2.1
• Python >= 3.0

We are compiling in C++11 mode, so recent versions of GCC are preferred. We also assume that you have a GUI and graphics driver installed.

Open a terminal and navigate to the directory containing premake4.lua. Type premake4 gmake. A Makefile will be generated. Type make help for usage information, or simply make to run the default debug build.
