Tutorial Lesson 5 Updated

[TerryRitchie]

UPDATE 04/22/24
--------------------

The PCOPY statement has been added to lesson 5 along with an example game highlighting its use. The tutorial asset file has also been updated to include this code.


UPDATE 04/13/24
--------------------

The _PIXELSIZE and _NEWIMAGE statements have been added to lesson 5. _NEWIMAGE was always included but now broken out to it's own section.

Legacy screens are now covered in the SCREEN section in lesson 5.

Screen pages and page flipping are now covered in lesson 5.

The tutorial asset file has once again been updated to include the new sample source code.

------------------------------

The DRAW, POINT, and PSET statements have been added to Lesson 5 of the tutorial.

The tutorial asset file has also been updated to incorporate the associated example programs that go along with the additions.

This is a big update, the DRAW command has a huge subset of commands to explain.

PSET was always included in Lesson 5 but just as a paragraph from another command. I broke it out to its own section.

Thanks, Terry! Will check it out.

Let me know if anything is unclear or needs to be added or corrected.

One thing I noticed which folks might find quite useful, that you might want to add:  _PixelSize.  This seems like an excellent place to include it in the tutorial, and it's quite useful in many instances, just so an user can figure out what screen they're working on.

PixelSize = 0 <-- Text Screen
PixelSize = 1 <-- 8-bit Screen
PixelSize = 4 <-- 32-bit color Screen

^Those can come in very, very handy -- especially if ever writting _MEM routines which you want to use across various screen modes.

Yes, _PIXELSIZE is definitely on the list for Lesson 23: Direct Memory Manipulation.

In lesson 5 I purposely avoid the legacy screens and introduce instead SCREEN _NEWIMAGE(). However, I do agree _PIXELSIZE should be covered during the SCREEN introduction. I'll expand on the SCREEN statement to include the legacy and 256 color screens and then explain how _PIXELSIZE can be used to identify them.

Thanks for the suggestion.
