Old School Laser Show
« on: April 21, 2021, 07:10:03 pm »
Hi all, I thought I would tinker with QB64 today to see if my imagination would spark anything finally. Well, instead of my imagination my memories went back to old old old school lasers. So after messing with it for a couple hours, I made this. It's 4 lasers at a time with a slight afterglow. I used only 7 basic colors so they would be bright and simple. It's always the simple stuff like this that recharges me. Also goes good with rock music. :)

Code: QB64: [Select]
  1. _TITLE "Laser Show - by SierraKen - Press Esc to end."
  2. SCREEN _NEWIMAGE(800, 600, 32)
  3. c1 = 255
