Re: [squeak-dev] [BUG]UndefinedObject(Object)>>doesNotUnderstand:

Hi Rafael,

You'll have better luck with these sorts of questions on the Croquet
mailing list (I'm cross-posting this response to croquet-user).

The "mouse move" problem actually appears to be a problem with your
OpenAL installation (notice that #isCurrent is being sent to 'nil'...
OpenAL is one of only 2 implementors of #isCurrent). Have you
installed OpenAL on your machine?

About the entropy warning... which VM are you running the image with?
There's a Croquet VM provided that has some special VM plugins. The
plugin "CroquetPlugin" provides a primitive to use the appropriate
platform-specific method of gathering entropy. One reason that you
might see the warning is because you're using a normal Squeak VM that
doesn't have the plugin. In fact, this would also cause the OpenAL
problem even if you have properly installed OpenAL on the machine.

Hope this helps,
Josh
