INTRO
|
|
|
|
This snippet of code is the XSB multiplayer engine, that is, the code
|
|
responsible for visualizing planes. It is provided totally as-is with
|
|
no guarantees of working or being rmotely useful.
|
|
|
|
Two files, XPLMMultiplayer.cpp and XPLMPlaneRenderer.cpp implement the
|
|
lib. You must include XPLMMultiplayer.h to use it, and provide a text file
|
|
with your plugin to config multiplayer.

HISTORY

|
|
|
PATH NAMES AND CROSS-PLATFORM CODE
|
|
|
|
Paths for XPMP are always "native". This means:
|
|
|
|
- Backslash separators on Windows.
|
|
- Forward slash separators on Macintosh and Linux.
|
|
- For Macintosh (which has both "HFS" and "Posix" style paths) posix paths
|
|
are used.
|
|
|
|
Clients initializing the library are responsible for passing paths in these
|
|
formats. (Macintosh clients can convert from HFS to Posix using the routine
|
|
HFS2PosixPath, which internally uses CFURL for the conversion.)
|
|
|
|
The X-Plane SDK uses native paths, but on Macintosh uses HFS paths. XPMP
|
|
on Mac converts paths from HFS to Posix at all points of interaction with
|
|
the SDK.
|
|
|
|
The paths in some X-Plane formats like OBJ can often have any directory
|
|
separator. These paths are always partial paths; XPMP converts them to
|
|
native separators when they are read in.
|
|
|
|
Therefore the following rules should be followed when using/modifying XPMP:
|
|
|
|
- Always pass native paths to the lib and expect native paths out.
|
|
- When getting file paths from external sources (like OBJ files) make them
|
|
native immediately.
|
|
- Mac only: In the lib wrap any SDK call with HFS->Posix conversion if
|
|
needed. |
