Editing Urho3D Demos

The sample applications start from the very simple (a "Hello World" program) and progress to demonstrate more complex engine features. The code is heavily commented and should be easy to follow for learning. The applications display on-screen instructions when run.

The AngelScript and Lua versions reside in the Bin/Data/Scripts and Bin/Data/LuaScripts directories. Batch files to run each of them are not provided due to their large amount: instead run the player application with the script file name as the parameter, for example Urho3DPlayer Scripts/01_HelloWorld.as

The C++ versions need to be explicitly enabled in the build with the CMake option -DURHO3D_SAMPLES=1. When enabled, the executables will be produced into the Bin directory and can be run from there. Their source code is in the Source/Samples directory.

The samples provide the following common key controls:
 ESC         Exit
 F1          Toggle console
 F2          Toggle debug HUD
 1           Cycle texture quality
 2           Cycle material quality
 3           Toggle specular lighting
 4           Toggle shadow rendering
 5           Cycle shadow resolution
 6           Cycle shadow filtering quality
 7           Toggle occlusion culling
 8           Toggle dynamic instancing
 9           Take a screenshot and save to the Data directory
== Building C++ Demos ==
When compiling Urho3D from source, set the compiler flag "URHO3D_SAMPLES=1" in cmake.

=== '''Linux''' ===
 ./cmake_generic.sh -D URHO3D_SAMPLES=1

=== '''Windows''' ===
