Here is a FGIO class derived from FGSubsystem that replaces the fgIOInit() and fgIOProcess() functions. The FGIO::update(double delta) doesn't use the delta argument yet. I suspect it could be used as a replacement for the calculated interval value but I'm not familiar enough with that piece of code just yet. I've also added two "command properties" to fg_commands.cxx that select the next or previous view. Writing any value to these properties triggers the corresponding action. As an example I modified my keyboard.xml: <key n="118"> <name>v</name> <desc>Next view</desc> <binding> <command>property-assign</command> <property>/command/view/next</property> <value type="bool">true</value> </binding> </key> <key n="86"> <name>V</name> <desc>Prev view</desc> <binding> <command>property-assign</command> <property>/command/view/prev</property> <value type="bool">true</value> </binding> </key> And of course these actions can also be triggered from external scripts via the props server.
