You are expected to collaborate significantly in this class, EXCEPT for those parts of the class that are specifically designated as individual work.  Each project or assignment will identify whether it is individual or group work.

Asking for help with Unity issues, suggestions for how to accomplish certain things, and so on is fine on these individual assignments;  as long as the project and prototype you create are yours.  For example, you can get a pointer on how to implement something, but you should then do the implementation in your project.

If you get code from somewhere, either a Unity tutorial, web page or forum, you are allowed to include it as long as you document what you got where.  The prototype should have a significant element of your work;  it is not acceptable to get a working prototype from somewhere and modify it slightly and turn it in.  The goal of the class is for YOU to demonstrate that you have learned how to create a working prototype.

If in doubt, ask.
