To have an sky having clouds in movement you need to add, to the function
"initialize" of the Class CobaltWorld:
tframe := TSkyBox new initializeWithFileName: 'JUL'.
tframe step. " Make the sky spin. "
space addChild: tframe.
Commentaries in Smalltakk are between quotation marks.
It works for Croquet-Cobalt and I imagine that it's working also for
Web-Cobalt, like you can test loading, at the "Cobalt browser":
(It's the same 3D lesson 4 with the new sky)
Please, let me know if it's working OK because, like I do tests at a "not
clean" computer, sometimes I think that all is OK, but it's not. Because my
Cache has many thinks that a "clean machine" doesn't have.
