OmniPeg - PhilOfPerth - 08-13-2023

Here is my version of the Peg Solitaire game, which has a couple of twists to the original. 
Coding is not economized, and could be probably halved by some members (?), but it works.

RE: OmniPeg - mnrvovrfc - 08-13-2023

The "WIPE" subprogram is handy for SCREEN 0 programs. Pete would love that one.

Have to use subprograms also just to set colors. Yellow! White! Because QB64 doesn't have "#define" like in C/C++ or something else to define a search-and-replacement macro. From this I could see Ethan Winer crying, "No! Stop! Use GOSUB subroutines instead, they are only three bytes per call!" LOL. I miss that PC-MAGAZINE BASIC primer that he wrote.

RE: OmniPeg - justsomeguy - 08-13-2023

Great little game! 

I had to make one change to it to work on a Linux machine. This font seemed generic enough to work a lot of distros.

Code: (Select All)
SetFont: f& = _LOADFONT("/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf", 24, "monospace") '                                                 31 rows, 73 columns text, allows chr$(95)

Thanks for sharing!
