Tutorial query - CGA editing

[RichardMorris]

Hi, I'm working through the CE Tutorials. 

Tutorial 6 asks us to edit CGA for the first time. If i cut and paste the code from into the Navigator (or if I type it in manually) I get the error message 'Unused function: ....". Please see attachment.

Any idea what I'm doing wrong?

Thanks

These are only warnings (not errors).  They are ok.  Your code will still run.  They just say that the functions being defined in these lines are not being used (yet).  Later in the tutorial, you add more lines of code which use wall_tex, dirt_tex, etc.
