  • compilation fixed
  • classes oscsender and oscreceiver ready to use

todo

  • finish the oscmsg (osc message) class to prepare messages in gdscript instead

windows compilation

  • all set methods are using Variant instead of typed arguments
  • utils contains methods to check variant easily
  • registration of methods and properties for gdnative
  • adaptation of godot macros ( see GODOT_SUBCLASS )
  • include and SConstruct adaptations, should be cross-platform

todo

  • enable OSCreceiver signal in OSCreceiver.cpp, line 285 (crash at compilation)
  • verify gdnlib & gdns in demo/bin/
  • debug loadong in gdscript
  • make OSCsender & OSCreceiver appears in the object selector in godot

gdscript

receiver = load("res://bin/OSCreceiver.gdns").new()

result:

ERROR: poll: res://bin/OSCreceiver.gdns:9 - Parse Error: Can't load cached ext-resource #1
   At: scene/resources/scene_format_text.cpp:587.

  • Fix linking oscpack shared object files

pitfall

  • SConstruct is definitely not cross-platform friendly, see comment in-file

Warnings

When loading the project, I get this in Godot's output window

 drivers/unix/net_socket_posix.cpp:301 - Method/Function Failed, returning: ERR_UNAVAILABLE
 modules/gdnative/gdnative.cpp:480 - No valid library handle, can't get symbol from GDNative object
 modules/gdnative/gdnative.cpp:386 - No valid library handle, can't terminate GDNative object
 Can't open dynamic library: /home/mis/src/gdnative_osc/demo/bin/x11/libgdosc.so. Error: /home/mis/src/gdnative_osc/demo/bin/x11/libgdosc.so: undefined symbol: nativescript_api

Also, in the console, possibly related to Frankie's todo point #4
