You know what's crazy? When he showed the little guy without the spikes jumping up and down, my mind still genuinely thought it was moving forward, even though there was nothing moving to the left to signify that, the fact that Flappy Bird had such a big effect on my brain that a small character jumping up and down tells my brain it's also moving right is insane to me

I think it's also the eyes of the character, the lines on the triangle are facing right so you've think if it was moving then it's obviously moving to the right and not to the left.

0:12 yes but a "line of code" is specifically defined. Hop into your visual studio and you can actually do a quick diag and it will tell you how many lines it is, ignoring whitespace.

LOL thanks haha, we’ll see about skyrim 👀

[@nathansnail]

Skyrim has multiple objects all with their own code and the game needs one manager object to do everything so it would be even more of a nightmare making more complex behaviours such as pathfinding. You could probably merge an open source engines code with your games making it truly 1 line.
