Someone on VCForum joked that I should make it "Find the kitten" -- apparently that's a thing on the internet -- so I did: https://tinyurl.com/kwalvsy It's silly but it uses everything I learned so far: how to move a sprite, how to make the joystick's 256 increments match the lores screen's 40 increments, how to combine static images with the moving image, how to generate random(ish) numbers, how to do collision detection, how to animate an image (by primitive method of redrawing over old image in background color, etc.), and how to restart by using the joystick button (already learned from previous Lego robot experiment). The real game will be a bigger challenge. Have to merge the robot code into the game framework (hey Brace and Dan, yes the main program is all subroutines), make additional collision detection for when you drive the robot over the screen boundaries, make obstacles, make a scoring system, improve the graphics, and optimize the code (even I understand it WILL get slow as it grows). Tools I learned to use in the robot + game process so far -- ADTpro, Cidepress. (Dan: turns out using Ciderpress is easier than you and I both thought. Just open the .dsk image, select your .txt file with the "convert to .BAS" option, and that's it -- it automatically adds it to your disk image; you don't have to re-save the image or use any compression formats. Discovered this by accident when I reloaded the program, but I forgot to re-save the image, and yet the new code was magically on the disk already.) ________________________________ Evan Koblentz, director Vintage Computer Federation a 501(c)(3) educational non-profit evan@vcfed.org (646) 546-9999 www.vcfed.org facebook.com/vcfederation twitter.com/vcfederation instagram.com/vcfederation
