You're not going to believe me, but the puts wasn't working in the Ruby console for the past 2 days, but it just started working right now. Ghost in the machine I guess. I'm still getting a crash when I run the motion_sample.rb script I mentioned above. I think it might have to do with not being able to access the gems, although there is no error message. I'm investigating it and will get back with any questions. Thanks again!

Hi Dan, Thanks a lot for the reply! Having the Java program write to a file and then having the Sketchup script read it in is a good idea. I'm going to try that. Can I use the 'File' object to accomplish this in a Sketchup script? Having said that, for me latency is an issue, and I don't know if the time for writing and reading from the disk will slow me down - but I guess I'll only know after I try. Actually what I am trying to accomplish is have a controller control the camera in the Sketchup model. The controller has APIs in a bunch of languages (Java, C++, Javascript), but none in Ruby. There is one interface created by a third party that uses SWIG to wrap the C++ functions and make it accessible in Ruby, but those are 'listeners', and I don't know if they would work within Sketchup Ruby. Do you know if it is possible to have the a .rb script, run via the Sketchup Bridge from within an IDE, that acts as a listener? (Sorry if this is a bit vague - I'm don't have much experience integrating a scripting language like Ruby with something like Java or C++. Let me know if I can clarify this further).
