JDeeth / PPL-Demo

Contains PPL and a demo plugin as subprojects for simpler building.

PPL-Demo

This is a demonstration of Philipp Ringler's Plugin Patterns Library, a set of C++ wrappers for the X-Plane SDK and OpenGL/OpenAL.

This uses my fork of PPL, which has a few minor additions. These are marked in the comments.

To download along with the git submodules, use this command:

git clone https://github.com/JDeeth/ppl-demo.git --recursive

then open ppl-demo.pro with Qt Creator. PPL and the demo plugin are included as QMake subprojects.

This project has been developed under Linux. plugin.pro will definitely need to be updated to compile under OSX and Windows, with the location of the compiled PPL static library and OpenGL libraries. If you're able to make these changes, please send a pull request! You should be able to compile PPL as a subproject immediately.

When compiling the plugin, add -recursive CONFIG+=withsound to the QMake settings in Qt Creator.

When testing the plugin, copy the sounds directory to the test aircraft folder.

This project currently demonstrates these features of PPL:

• DataRef to access existing datarefs
• OwnedData to create new datarefs
• Processor for flight-loop callback functions
• ALContextManager to play sounds
• PluginPath
• Log and LogWriter
• MenuItem and Action for menu items
• MessageWindow
• OnScreenDisplay

These features are not demonstrated yet:

• OwnedData and DataRef with arrays and custom callbacks
• Command for accessing and creating commands
• DrawCallback for managing drawing-loop callbacks
• FontMgr to draw TTF fonts
• LogicHandler, kinda a more baroque Processor
• OverlayGauge, an OpenGL context for drawing on the 3D cockpit and in popup windows
• Settings, a wrapper around SimpleIni
• Smoothed, a very simple filter for smoothing out changing data
• Texture; loads a bitmap for OpenGL drawing
• VertexBuffer; wraps an OpenGL Vertex Buffer Object. Uses glMapBuffer.
