Portal speedrunners were just trying to skip a small portion of a cutscene, but they ended up finding an invincibility glitch in the process. How exactly does that happen?

Eight years all for a trick that saves 10 seconds. Speedrunners are so cool.

"It takes 3000 days to practice this skip.. of 10 seconds; who touched my portal gun?"

[@bolson42]

“I was thinking about why so many in the radical left participate in "speedrunning". The reason is the left's lack of work ethic ('go fast' rather than 'do it right') and, in a Petersonian sense, to elevate alternative sexual archetypes in the marketplace ('fastest Chell'). A "speedrunner" may well spend hours a day at their craft, but this is ultimately a meaningless exercise, since they will ultimately accomplish exactly that which is done in less collective time by a casual player. This is thus a waste of effort on the behalf of the "speedrunner". Put more simply, they are spending their work effort on something that someone else has already done (and done in a way deemed 'correct' by the creator of the artwork).” this comment is satire btw, although the source sadly isnt

[@maximusthedude8305]

Chad Portal 2 speedrunners discover invincibility, run is so optimised it only saves 10 seconds. Incredible

[@tylisirn]

I'm actually not hugely surprised. You don't encounter turrets that often and turrets have relatively huge grace periods before they activate, so by going fast you can do quite a lot in front of them even without invincibility. And the liquid pools are generally functionally "bottomless pits" so being able to swim in them benefits little since they rarely have a way out of them.

[@sunvieightmaster88]

There are many reasons I like speedruns. One of that reason is discovering something accidentally.

[@bjiggles8145]

In the years after Chell's escape, she's seen getting hit by a car and gets up with no injuries. Accident witness: Holy crap are you okay! How did you survive that?! Chell: I used a clipboard a while back, looks like it hasn't worn off yet.

It gets even crazier when you are messing with cheat codes to find bugs. I'll give an example of one I accidentally found: there's a entity dupe glitch you can do in the advance wars game "dark conflict" on the nds, you essentially run a code that lets the player take another turn, but if you put a unit on a ship during your turn, then run the code, your unit is cloned somehow.

[@nolram]

The reason Players get dragged but not physics props is because the use a different physics system. The physics system of props, Vphysics (internally the Havok physics engine) is not the same as the engine controlling NPCs and the player, which are controlled by something called QPhysics, which is the physics system inherited from GoldSrc, which inherited it from Quake which it is based on (thats why is called QPhysics - Q for Quake). QPhysics “glues” the player to the platform so they move along with it, as you can see on any moving platform in the game - however this also applied to animations.
