Human ingenuity is a powerful\u2014sometimes terrifying\u2014thing. Throughout history, no matter how basic the tools available to us, we have always found a way to build the weird obsessions that appear in our minds. You know, like Stonehenge, or the Pyramids, or Doom (1993).<\/p>\n

No, really. In a recent chat with Jesse Petrilla on YouTube<\/a>, id co-founder and Doom lead artist Adrian Carmack revealed that, when it came time to put together the classic FPS’ animations, the incredibly complex and advanced animation tool he used to do it was\u2026 the undo key.<\/p>\n

“As an artist, oftentimes you end up making your own tools,” said Carmack. “You know, there was no animation tool, so I started using the undo key to create animation\u2014the undo key in Deluxe Paint, so I’d go back and forth.”<\/p>\n

If you’re unclear as to how that works, remember that animations in original Doom weren’t really animations as we think of them today, with models seamlessly transitioning through countless subtle movements to create smooth motion. Doom sprites, from your enemies to your weapons, were all very frame-y indeed. Working with relatively few frames meant Carmack could create and capture animation loops by cycling through frames in Deluxe Paint using undo\/redo.<\/p>\n
