Crossbridge-Recast-Navigation

This project is a FlasCC port to ActionScript 3.0 of C++ navigation mesh library Recast Navigation by Mikko Mononen.

Usage

In order to integrate the library with your project simply add as3_lib/bin/Crossbridge-Recast-Navigation.swc to it's library path.

Demo

Live demo in Flash featuring some of Recast Navigation capabilities is available here. It's source code can be found in demo folder.

How to build demo

To build demo from source you need to add demo/src and demo/themes folders to source path, add lib folder to library path. You can use html template from demo/html-template folder or use your own, but don't forget to set wmode parameter to "direct" as it is required by Starling Stage 3D rendering. Input geometry meshes are in demo/meshes folder.

How it's all organized

FlasCC compiler is used to generate swc library with internal API which is further used in final AS3 library project providing easy to understand AS3 API. Final product preserves original API as much as it's possible.

Internal API

Using FlasCC compiler you can manually expose C++ functions to AS3. Study this example to understand how it's done. Internal API creation code is in folder as3_internal_api. To build as3_internal_api.swc run crossbridge_compile.sh from Crossbridge environment. You can also run crossbridge_launcher.bat providing it with path to Crossbridge folder as an argument.

AS3 Library

Final AS3 library wraps internal API methods and C++ structures and classes. It creates simple AS3 classes and functions so it can be easily used in standard AS3 workflows. Most recent version of it is always available in as3_lib/bin folder. But you can build it yourself. You need to create an AS3 library project with source from as3_lib folder and add as3_internal_api/as3_internal_api.swc as a library. You can also add -inline as an additional compiler options.
