TF2's Door Problem

I find it funny how almost all of these problems are caused just by mappers using the smallest grid size

Yes I WILL watch a 15 minutes video about the doors in the Team Fortress 2 video game!

7:13 There's a check that happens every item Pyro attempts to use his flamethrower meant to prevent this from occurring. Standing inside a teammate causes the check to be disregarded and the particles spawn anyways. I think Shounic covered it at one point.

I know exactly why the dustbowl door opens upside down. It happened to me. Look above it. Imagine the door’s size. It WILL go up and create an invisible wall on the roof. The ceiling isn’t big enough to hold the door inside. So we make it go down instead. Good thing they caught on that, because it’s hard to notice it if you playtest alone, I mean, who’s gonna open the door for you if you’re above ?

Why doesn't valve just hire this guy

You should make a compilation (guide) of mistakes that map makers can make. So that when a new map maker wants to create a map, they know what mistakes to avoid.

I think one of my favourite doors is upward blu forward spawn in the tunnel. The door brush opens upward, meaning if someone is in the tunnel segment above the spawn they collide with the door. In an open state it pokes about 40 units out of the ground.

If you haven't died to a spawn door in mercenary park, you haven't played TF2 the right way! 😂 Great video, dude!

Most of this problems come from the fact their didn't use instances back then, a instance is like a piece of a map with props, triggers, door etc, so instead of making the same door over and over you make it to a instance and then just reference it all the times that you need it. And if you find a bug, change the instance and it gets updated to all the maps that use it(they need to be recompiled). Valve enforced instances when building Portal 2's maps, the puzzle's devices are also made from a bunch of different entities working together, if every time these get used the devs change some of them or have to make them from scratch these are more prone to develop problems.

I like LED. He dosen't try to sound smarter than everyone else, makes good and informative videos, and isn't afraid to admit when he doesn't know something. Keep it up! 😊

I actually did not know about that door on Frontier permanently closing

for the door launch section of the video (11:10), the func door likely moves down so players standing above the door wont get blocked while trying to walk through it while open. this is a problem in some other community maps, but is most notable above blue's 2nd spawn on upward. once the door is open, you cannot enter the side tunnel without crouch jumping over the door.

LED is now like the 3kilksphilip of tf2

I think the hoodoo door may have something to do with the sign above it, maybe it has that wacky collision like some of the signs on upward, causing the door to ignore any players blocking it

4:55 Love how heavy wastes no time punishing scout for existing

As someone who has been curious to get into mapmaking, thank you so much for this guide on how to let enemy players into spawn. I'm always disappointed when a map doesn't have at least one funny exploit you can do, so being able to make sure there's at least one on any map that I make really warms my heart.

I expect a detailed tier list on every TF2 door soon

13:46 sounds like it could be a floating point issue. Try placing the door in the same worldspace coordinates as well

the door on dustbowl isnt set to down because "valve didnt notice", its because otherwise the invisible door brush would clip through the top of the walkable area above the door, this is also why they used the animated prop instead of the parented one.
