Great advice and equally applicable to real life. By assuming positive intent you're counteracting the Fundamental Attribution Error.
tendency to attribute another's actions to their character or personality, while attributing their behavior to external situational factors outside of their control.
Otherwise you're likely to spend a lot of time being angry at people who don't really deserve it. Or even if they do, it's just not worth your mental energy being upset.
I'm not in the industry, but I've dabbled in Unity and that's just kind of how it works by default. You create a game object and it gets an Update() function that is called once per frame. You're encouraged to perform calculations and update it's position in that callback.
You're supposed to use
Time.deltaTime
to scale your calculations based on how long it's been since the last frame.But that takes effort and it's very easy to just not do that and your game will still work fine in most cases.
