Horde3D

When a resource isn't loaded successfully, I can see an entry in the log file. But from the code side this isn't really helpful. I can still apparently possible to successfully add nodes from a resource that wasn't successfully loaded, as apparently it does no error checking or at least it returns a nonzero node. (I think it *should* do error checking even if it's a bit slower though).

There is no utility function to only load a single resource from disk (well, I guess I'll have to write one). Wouldn't it be nice to just be able to check whether a resource is loaded or not, after calling loadResourcesFromDisk?

In addition to the patch below, I think adding nodes from the resource should also fail.

I won't make separate patch, but just paste the changed I made here because my diffs show extremal amount of windows linebreaks... Also the whitespace seems to get smashed when I paste here, but it's just a matter of indenting it again.

in egMain.cpp


in Horde3d.h

Thanks for these hints. The isResourceLoaded functionality can be useful in some cases.
I also just discussed with Volker the best behavior when calling addNodes with an unloaded resource and it makes sense to return 0 since the scene graph will not be updated automatically even if the scene graph resource is loaded later.
