Portal 2 - Crouch Flying Glitch - Theory, Fast Entry, and Flying Objects

First this video just talks about how to do the crouch flying glitch. It then goes through a little theory about why I think things happen the way they do.

At 5:00 it starts talking about offsetting portals, which lets you become crouch flying glitched much faster, and also lets you make some objects fly.


Two things about CFG Theory that I forgot to mention in the video:

1: When you save and load the game, it loses track of which excursion funnel you're in, so flying into one sets your gravity flag to false (it's already false but whatevs) and hooks you up to that tunnel as if you were never glitched in the first place. This is why flying into funnels after saving brings you out of the glitch instead of changing your altitude.

Additionally, you can un-crouch after saving and loading. Usually un-crouching runs the "You exited the excursion funnel" script (Unless you initiated the glitch against a wall. In that case, you end up glitched as long as you remain standing, and crouching ends the glitch). When you save and load the game, your connection to the funnel is gone so it doesn't run that script when you stand up.

2: The gravity flag is attached to your player, not the level or whatever, and if it's set to false, it remains false. That's why you can retain the glitch into the next level if you start it using the main funnel that comes out of the machine. If you use two portals to create a second funnel segment and use that to glitch, it will not be retained into the next level because that segment will be destroyed and set your flag to true when you pass through the emancipation field.

thats wierd i start flying a little bit around the room and then like3 secs later i fall down do i have to press something to make me stay up

[Negatratoron]

@BBRyanDudeDawg Yeah, you need to remain crouching. (If you have a low roof over your head (like if you are right up against the ceiling) you don't need to physically hold the button.)

this works on xbox 360 but it's slightly harder to do.

i know em all before whitout help from anny videos (did u know that all can be done on xbox + u can take it with u in the elevator?)

[AgentCannonball]

I like how you explain the glitches. Nice job!

[NabsterHax]

You don't need to jump by the way. The basic principle is:

1.Come to a complete halt at the end of ExFu, vertical or horizontal.

2.Change crouch position (Crouch, if uncrouched. Uncrouch if crouched. You can crouch, then uncrouch again)

3. Fly out.

If the ExFu you used was redirected via portals, moving the portals will destroy the glitch. Changing crouch state in air again will also remove the glitch. You can also stand on the ground while glitched, but you cannot jump if you are crouched.

i like it when stupid stuff like placing the wrong portal happens not only to us, but to professionals as well xD

@TheZB17 As far as I know this is PC because you can't really do scripts on console.
