When an unknown bug appears in the game and causes destructive impact on the game environment, any normal developer would first think about fixing the bug.
Huang Wenjun is no exception.
But when he tried to troubleshoot and fix the bug, he was astonished to find that this bug wasn't closely related to the game itself, but was a feature inherently backed into the engine.
This explanation might be hard to understand.
To put it in simpler terms, take the well-known Origin Engine as an example, this engine has a well-known feature: extra acceleration!
While maintaining movement and rotating your view at a constant speed, combined with A/D input, you will gain an acceleration value based on the degree of view rotation...
This is the root of many peculiar combat techniques, like aerial acceleration, midair direction change, abstract position jumps, that are realized in games developed with the Origin Engine.
