  • I posted this before I carefully read the comments. I now know the OP already knew about SNAKE.BAT. Commented Dec 1, 2013 at 5:02
  • that is fine, i had not understood the game as well before, and i learned more from this post than i did from reading through your code for three hours every night for a week. i had thought that the screen painting was for the snake effect, not optimization. i did wonder: is it better to set a line of enimies at the top, and execute code that changes what is displayed only if there is a hit, or is it better to re display it every time, so that the time for display always take the same amount of time. i guess you hit two birds with one stone. would it be too much to ask for you to explain cont.

  • how i could implement a fixed amount of time in my code? i think i can figure the rest out, but i dont quite get that. Commented Dec 1, 2013 at 5:31
  • @nephi12 - See my edited answer. If you have additional questions, then I suggest starting a new SO question for each specific programming topic. Your question here is a bit open ended for SO. Another alternative is to join DosTips and start a thread there. The format there is a bit more free form, with lots of back and forth and collaborative brain storming. Commented Dec 1, 2013 at 15:02
