# PGE Template Project v2.25
This is a template project for use with the [olcPixelGameEngine](https://github.com/OneLoneCoder/olcPixelGameEngine). It serves as a jumping off point for you to build your masterpiece application.
## Features
CMake script for cross-platform building. Tested environments include:
* Linux - with UNIX Makefiles, GNU GCC and LLVM Clang
* MacOS - with UNIX Makefiles, XCode and LLVM Clang
* Windows - with Visual Studio, NMake Makefiles, and MinGW Makefiles
* Emscripten - with UNIX Makefiles, NMake Makefiles, and MinGW Makefiles
# Preparing your Environment
The instructions to prepare your environment have been broken up for convenience. Simply follow the instructions that are pertinent to your situation.
## Linux
### **Requirements**
* C/C++ Toolchain for your Linux distro
* CMake
* Git
* libpng
* Mesa OpenGL Development Libraries
### **Ubuntu and Ubuntu based distros**
Update your package manager by issuing the following command:
```
sudo apt update
```
Install toolchain and required software by issuing the following command:
```
sudo apt install build-essential cmake git libpng-dev libglu1-mesa-dev
```
### **Arch, Manjaro, and Arch based distros**
```
sudo pacman -Sy base-devel cmake git libpng mesa
```
## MacOS
### **Requirements**
* XCode
* [Homebrew Package Manager](https://brew.sh/)
* libpng
* CMake
* git
Install XCode from the App Store.
Open the ``Terminal`` App from Finder. go to Applications -> Utilities
Follow the instructions at the [Homebrew Website](https://brew.sh/) to install the Homebrew package manager.
Once Homebrew is installed, issue the following command to install ``cmake``,``libpng``, and ``git``:
```
brew install libpng
brew install cmake
brew install git
```
## Windows
### Requirements
* Chocolatey
* CMake
* Toolchain (MinGW or Visual Studio / NMake)
The following will be required whether you use MinGW or Visual Studio.You will need to open Powershell, as Administrator.
Visit the [Chocolatey website](https://chocolatey.org/) for instructions on how to install Chocolatey.
Once you've got Chocolatey installed, we can install CMake:
```
choco install cmake
```
Say ``yes`` to all of the scripts Chocolatey wants you to run!
After the installation has completed, find the Cmake ``bin`` directory, it is typically ``C:\Program Files\CMake\bin`` and add it to your path!
Confirm CMake is installed and in your path by issuing the following command in a Command Prompt:
```
cmake --version
```
If you recieve an ``command not found`` error double check that you have actually added CMake to your path.
## MinGW
Install MinGW via ``choco install mingw`` from Powershell as Administrator
## Visual Studio / NMake
Download and install [Visual Studio: Community Edition](https://visualstudio.microsoft.com/downloads/).
Ensure that you have installed the Desktop C++ option!
# **Usage**
IF YOU HAVE MADE IT HERE AND YOU HAVE NOT SET UP YOUR DEVELOPMENT ENVIRONMENT, GO BACK UP AND READ THE INSTRUCTIONS AGAIN!
## Linux / MacOS (with default toolchains)
Open a Terminal and navigate to the directory which you downloaded the project. Issue the following command:
```
cmake . -B linux-build -G "Unix Makefiles"
```
CMake will generate UNIX Makefiles you can use to build the project, like so:
```
cmake --build linux-build
```
The compiled binary will be located in ``linux-build/bin`` directory.
**NOTE: if you're executing the program, ensure you have the correct working directory, which contains the executable!**
## MacOS (with XCode)
Open a Terminal and navigate to the directory which you downloaded the project. Issue the following command:
```
cmake . -B xcode-build -G "xcode"
```
CMake will generate an XCode project in ``xcode-build``. You can use it like any other XCode project.
## Linux / MacOS (Emscripten)
**These instructions assume you have Emscripten installed, activated, and have the environment set up for an active Terminal.**
Open a Terminal and navigate to the directory which you downloaded the project. Issue the following command:
```
emcmake cmake . -B emscripten-build
```
Emscripten's ``emcmake`` utility will invoke CMake with all the magic required to make it work with Emscripten. Generating UNIX Makefiles you can use to build the project, like so:
```
cmake --build emscripten-build
```
The compiled HTML, Javascript, WebAssembly, and Data will be in the ``emscripten-build/bin`` directory.
If you lack some sort of live server extension to your IDE, you can view it using the ``emrun`` utility, like so:
```
emrun path/to/build/bin/PROJECTNAME.html
```
This command should launch the project in your default web browser.
## Windows (MinGW)
Open the ``Command Prompt`` prompt and navigate to the directory which you downloaded the project. Issue the following command:
```
cmake . -B mingw-build -G "MinGW Makefiles"
```
CMake will generate MinGW Makefiles you can use to build the project, like so:
```
cmake --build mingw-build
```
The compiled binary will be located in the ``mingw-build/bin`` directory.
**NOTE: if you're executing the program, ensure you have the correct working directory, which contains the executable!**
## Windows (NMake)
Open the ``x64 Native Tools Command Prompt for VS 2022`` prompt and navigate to the directory which you downloaded the project. Issue the following command:
```
cmake . -B nmake-build -G "NMake Makefiles"
```
CMake will generate NMake Makefiles you can use to build the project, like so:
```
cmake --build nmake-build
```
The compiled binary will be located in ``nmake-build/bin`` directory.
**NOTE: if you're executing the program, ensure you have the correct working directory, which contains the executable!**
## Windows (Visual Studio)
Open the ``Command Prompt`` prompt and navigate to the directory which you downloaded the project. Issue the following command:
```
cmake . -B vs-build
```
CMake will generate a Visual Studio solution and project in ``vs-build``. You can use it like any other Visual Studio Project.

| OneLoneCoder Pixel Game Engine Extension |
| MiniAudio v1.5 |
+-------------------------------------------------------------+
NOTE: UNDER ACTIVE DEVELOPMENT - THERE MAY BE BUGS/GLITCHES
What is this?
~~~~~~~~~~~~~
This extension abstracts the very robust and powerful miniaudio
library. It provides simple loading and playback of WAV and MP3
files. Because it's built on top of miniaudio, it requires next
to no addictional build configurations in order to be built
for cross-platform.
