[vos-d] Terangreal OSX again
Hello everybody,
Good news from the Ter'angreal on MacOSX front! Well, sort of...
By accident I found the reason why terangreal (and assumedly
wxterangreal) just get stuck when I run them on my Mac. Terangreal
uses its own main event loop (main.cc), which emulates the functions
of the default CrystalSpace run loop. However, on the Mac CS needs to
use a *different* run loop, as the code in csutil/generic/runloop.cpp
clearly states. And sure enough, there is a different one in csutil/
macosx/OSXAssistant.cpp.
So I changed the code of apps/terangreal/main.cc like this:
if (terangreal->Initialize ())
{
/*
while (!terangreal->wantToQuit) {
terangreal->DoFrame();
}
*/
csDefaultRunLoop(object_reg);
}
and sure enough, when starting it the "busy" spinner disappears!
I can even rotate the view by dragging the mouse!
Apart from that however, I cannot move around or anything. I assume
Terangreal handles keyboard input etc. by itself in its custom run loop?
Still, it is a step in the right direction... But since I know next
to nothing about CrystalSpace, and even less about WX, could someone
more versed in these arcane arts please fix (wx)terangreal to use
csDefaultRunLoop() ?
Thanks,
Karsten Otto (kao)
...Cross-platform development is such wonderful and fun thing to do...

This has less to do with dynamic typing than memory management... in C++ you can dynamic_cast any object. MetaObject and meta_cast are partly ways to add more structure to dynamic_cast and C++ polymorphism. The only thing is, you have to actually cast *to* something, it's not like some languages where you can just call a method and the object either responds or fails to (silently or not).

Re: [vos-d] Re: [OFF] typing
Well, all you'd need in a Python errorchecker like that, is to (a) make it mandatory for the programmer "declare" member variables, then (b) parse the code and print a warning if you use an undeclared variable. (There are other kinds of programming errors too, of course.) Maybe such a thing exists?

Oh good, on-topic discussion :-)

Oh man. I forgot that Cocoa was annoying like that and didn't provide a
GetEvents() type function. Which means Cocoa absolutely, positively must
control the toplevel run loop and makes cooperative run loops impossible.
I guess you should expect this kind of control freak behavior from a
company run by Steve Jobs :-)
So I changed the code of apps/terangreal/main.cc like this:
if (terangreal->Initialize ())
{
/*
while (!terangreal->wantToQuit) {
terangreal->DoFrame();
}
*/
csDefaultRunLoop(object_reg);
}
Okay, this is probably a valid fix, provided we still have a way to quit
:-)

Does the entire scene load correctly? You mentioned you were having
problems with that before? Also, for mouse navigation, you use the right
mouse button (command-click in OS X I think?) to toggle between mouselook
mode and browsing mode, and in mouselook mode the left mouse button makes
you walk forward. So if the mouse works, you should be able to move
around.
Apart from that however, I cannot move around or anything. I assume
Terangreal handles keyboard input etc. by itself in its custom run loop?
Perhaps it is failing to get keyboard focus in some way? Does walktest in
Crystal Space work? All the keyboard handling in terangreal is with the
event system provided with CS, we arn't doing anything strange.
Still, it is a step in the right direction... But since I know next to
nothing about CrystalSpace, and even less about WX, could someone more

WxTerangreal uses the Wx runloop, which should itself be implemented using
the Cocoa runloop. The wxgl plugin takes wx events and translates them
into CS events. I don't think there should be any problem there... The
place to start is really with the "wxtest" program in CS, which I think
you mentioned does not work either (it should be displaying a room which
you can move around in)? You might want to bring this issue to the
Crystal Space mailing list.
