Playing games can desensitize you to the fact that they're really an amalgamation of number and letter strings, each of which was painstakingly placed in the proper order. This Matrix-like wizardry isn't often seen in full, but Daniel Tabár of Data Realms has done us the kindness of offering a window into the intricate labor that goes into coding a game.
In a series of three videos spanning nearly five hours in total (!), Tabár walks us through his process for adding the Techs feature to the indie sidescrolling shooter Cortex Command . You might recognize the game from 2010's Humble Indie Bundle 2 —now see a fraction of all the work that went into making it.
For aspiring game programmers, watching Tabár fly through source code making tweaks here and there should be a treat. Even if you can't discern a line of data from the lucky numbers in a fortune cookie, it's fascinating to watch Tabár work while he thinks aloud in a calm and informative tone.
