Portal Speedrunners Found An In-Game Aimbot (And It's Not Cheating...)

[@Msushi]

Something I didn't mention in the video is that runners can easily change their mouse sensitivity on the fly mid-run by binding it to a key-press just like any other action. Its as simple as typing into the developer console "bind [key] 'sensitivity [value]'", and then pressing [key] changes your sensitivity. i.e. "bind 1 'sensitivity 3000'" changes the sensitivity to 3000 when you press 1. And yes, the legitimacy of viewsnap is debated by Portal speedrunners to this day, many still don't like performing it in their runs.

[@ruinenlust_]

Thank you for this addendum :)

[@Pyrodiac]

I found that obvious, but I can see how some people were confused. And yes I have no idea why anybody is thinking we shouldn't be using this.

[@ArtturiSalmela]

Msushi forgot to say it in the video, but changing the sensitivity is probably done with keybinds that the runner would prepare in advance through the console. You could use something like the number keys for the different settings; Q for normal, 1 for chamber 1, 2 for chamber 5 and so on. Adjusting the mouse's dpi can be changed similarly.

It is TAS idk why they say it’s not. using the “console”(tool) to do things that are entirely impossible for humans in a speedrun is a TAS.

[@stuffed1322]

Fun fact: There are seamshots which are big enough to abuse easily in Team Fortress 2 - so big that even calling them seamshots is generous because it's basically a whole door border that you can shoot through, no viewsnap required. Best example being on gully wash shutter (the door connecting to upper lobby, straight ahead from left spawn). This problem was serious enough to be banned in competitive TF2 leagues, and remains so to this day.

[@otakusatanist]

nothing usable on normal servers but cleavers clipping trough glass on trade plaza was always fun to do

[@asdffdsa8885]

Those aren't true seamshots at all since they're still inbounds, just parts of the map where the developer forgot to add collision. The source engine REALLY doesn't like it when maps have any sort of "leak" out into the void, so the whole map has to be completely enclosed in order for it to load correctly. That's also why out-of-bounds objects in source engine games are always placed in their own little rooms. The seamshots in this video are leaks so small that even the engine isn't aware that they exist until you shoot through them, so they don't cause any issues when creating the map. Another fun fact: If I remember correctly, those shutter doors only have collision on the shutter itself, the frame that surrounds it is a separate model that isn't solid by default. So if the map creator forgets to make it solid or put something solid behind it, the doorframe can leave a gap above the shutter that's wide enough to shoot through.

Play at a higher dpi but lower your in-game sense to keep the same edpi, you can find calculators for this. This should increase the "resolution" you can use. It may make you more jittery until you get used to it. I use this technique in valorant to teach others how to aim when they start out. From 400 to 800 to 1600 dpi, any higher doesn't really make a difference. I stand corrected, 3200 DPI does actually make a difference. But only in certain edge cases. Playing aim labs I find that I either overshoot or undershoot and upping the DPi seems to give me a little more leeway when aiming, despite having the more then enough resolution to hit a target.

btw I'm pretty sure you can figure out m_pitch and m_yaw values in addition to sensitivity so that all you have to do is move one step in both the X and Y directions.

I think the part about sensitivity is also very noticeable if you use a very low desktop resolution (640 x 480 or something)

[@D0Samp]

But only if you have raw input disabled, right? Traditional game input works by periodically re-centering the invisible cursor on the screen and polling its position as a vector of motion, so it's quantified further by the screen resolution. But with raw input on, the actual mouse data is received and scaled by sensitivity (as well as m_yaw and m_pitch that define how large of an angle 1 unit of horizontal/vertical sensitivity is) to get changes to yaw and pitch. That said, people are stating that an average 800 dpi mouse is roughly pixel-equivalent to a Full HD resolution, so you can expect similar results by dropping hardware sensitivity to about a third of that.

This sounds kinda reminiscent of the airboat run in Portal 1, wherein ch_createairboat wasn't protected by sv_cheats, so _technically_ it's a legal move, right? Except that got banned outside of a joke category, and meanwhile this is apparently allowed? I don't really like it since it's essentially making macros that automate (admittedly small) parts of the game, which feels like it should be TAS category

[@mlugg5499]

It's not really the same. In general, the rulesets for both Portal 1 and 2 aren't based on sv_cheats protection: that may be taken into consideration but it's certainly not the defining factor. So ch_createairboat unambiguously *was* cheating, and everyone knew that: but someone joked about it being allowed, hence those runs and that category. This, on the other hand, is just adjusting an option which the game gives normal users: you could do it without even enabling the developer console. On that note, there's a bit of a difference between Portal 1 and Portal 2 here. Portal 1 provides the user with a text field in the options so they can input any sensitivity; this means anti-viewsnap sentiments don't really have an objective basis because they can literally be performed without doing anything a normal player wouldn't do. In Portal 2, however, we only get a sensitivity *slider* which caps out at 20 - this was the main justification for the 20 sens cap that was temporarily implemented. However, we already allow sensitivities far below 1 (the minimum on the slider), so it was much more logically consistent to not have the ban (and as Msushi discussed, capping sens at 20 didn't stop viewsnaps anyway). Last note: binds. You could argue that the bad thing here is that you can press a single button to change your sensitivity, and that a bind should only be allowed if it can be set in the menu. That's a reasonable opinion: it's what we'd call a more "purist" perspective but it's totally valid. But the way these communities have evolved has led, through essentially community consensus, to the rules for what binds are allowed being more open than that: Portal 1 is much stricter than Portal 2 but is still significantly less strict than the purist interpretation.

[@falsche921]

@@mlugg5499 Thanks for the input. Honestly I still don't like it much. It feels like it both uses control methods outside of what would be available to a typical player as well as ignores certain limitations of the game. (can the slider actually be used to set the game, say, to sensitivity 19.97561? To quote the video, "it's more like a grid, where your mouse can only be at certain points at a given time". Is there actually a point the mouse can be in that corresponds to those settings?) But I suppose at that point it's a matter of opinion. Although a last question: Why was sensitivity below 1 accepted in the period when sensitivity above 20 was banned? I don't really understand that part.

[@CAPTAIN_CLOCK]

Not really. HL1 and 2 both have scripted categories, and it's all allowed. I can see this being set to its own category, though, but I doubt it.

[@nereithr]

> It feels like it both uses control methods outside of what would be available to a typical player as well as ignores certain limitations of the game This is nonsensical because the console has been available (either by default or activatable from the in-game menus) in Source Engine games since the HL1 days. Moreover, you don't even need the console because you can achieve the same by editing config files directly (and setting up the necessary binds there). Arbitrarily limiting the precision with which you can set your sensitivity is just that: arbitrary. > Why was sensitivity below 1 accepted Pure speculation, but you can't really ban sens below 1 unless you want to lose a ton of players, because if you are a low sens/high DPI player then banning any sens below 1 pretty much bans you from playing the game. For instance, my current sens in CSGO is 0.9@1000 DPI, which isn't that low in the community as it is around 42 cm/360. If I played at a higher CPI my in-game sens would need to be even lower to compensate. Banning sens above 20 may make more sense initially because nobody *actually* plays on low CPI and ultra-high sens (this is not beneficial in any game). but it was still ultimately a dumb decision. > I don't really like it since it's essentially making macros that automate These are just sensitivity change binds. You might as well ban ADS in single player shooters with ADS since that changes your sensitivity as well. Also, an important distinction making binds different from macros is that binds only allow you to execute one change with one keypress, while macros (using alias in console) allow you to perform several actions. Binds are pretty universally allowed in both speedrunning and pro scenes, while actual macros are banned. For example, in CSGO it is fairly easy to create a jumpthrow macro, which releases your fire button at the same moment as your jump, allowing you to throw 100% consistent smokes. This macro is banned in pro play and also 3rd party leagues, precisely because it is a macro, but achieving the same effect by binding -fire to a key next to the spacebar and pressing both buttons at the same time is not.

[@mlugg5499]

@@falsche921 yeah, chances are the slider couldn't actually be used to enough precision to set values that precise anyway. Like I say, this issue only affects Portal 2 (in P1 you literally get a text box where you can type any number your heart desires) but it's still a fair point since there's no reason the games' rules should be in sync. As for why sens < 1 was allowed: essentially, this rule was put in place to try and ban viewsnap, because people deemed it a trick that didn't think should be allowed. Of course, that's not really what happened, but it was the intention. Sensitivities under 1 are a crucial part of the run, and have been for years: they're the "usual" method for performing these incredibly precise shots (such as seamshots). On a strictly objective basis, there's not really a reason to prefer sens < 1 to sens > 20, but in the context of this rule, sens > 20 was the "problem" and banning sens < 1 was essentially impossible because of how widely used and liked it is.

[@DarkKyugara]

The problem here is the usage of the console, and console commands... If I'm allowed to use the console command, why am I not allowed to use noclip? I think the answer is the same as every single other issue that Speedrunners had to deal with different strategies: Multiple categories. We can have a category that allows viewsnap and a category that doesn't, pure and simple.

[@falsche921]

The issue with making it a category is that... well, effectively it's the exact same run, the same route and strategy. It's just that in one case players would spend a few extra seconds firing portals into a corner until they shoot through, and in the other one they won't. Airboat% was different enough to make it a category, this just isn't

[@DarkKyugara]

@@falsche921 So, if this isn't enough to need another category, this isn't enough to have a debate in the first place, right? So... Nothing changed.

[@clairevoyanceSLA]

allowing console =/= allowing every console command source games usually have a whitelist of commands and noclip is not on there

[@ryogahibiki3838]

I didn't know about that, but i did knew about aimbot in cs go and kovaak for mainly practicing aims, its kinda intriguing how those affects into single player games and campaigns of source games just for aiming precise for speedrunning like L4D 2. Good explanation, i understand well on CC. Good job on ur video, sushi!

[@AveryChow]

I believe 3klicks covered something similar in CS:GO where he discussed whether it's better to have a high sensitivity in game but a low mouse sensitivity, or a low mouse sensitivity but a high in game sensitivity. he found (either by accident, or on purpose) that with low DPI and a high in game sensitivity, your crosshair would skip pixels across the screen. really cool to see a practical use for low DPI and high game sens lol.

[@ZipplyZane]

Seems to me that, if it's allowed, then the set-up time should count as part of the run.

[@ProSureString]

It’s not allowed, most of the times seam shots are done in the middle/end of the level.

[@Kris18]

This is a great video! I have a question though: does the community refer to it as aimbot? Unless something is missing, it's definitely not even close, and the title is misleading at best.

[@user-rf5hr6ek8x]

this tech was also figured out by some tf2 jumpers independently a few years ago but it got banned from being used in runs. very interesting to see a different decision being made by the portal community on the exact same concept

[@SinisterShrink]

I'm honestly surprised that use of the dev console is allowed at all for official runs. Feels like that should be put into a different category (unless it is already, all I saw was SLA/No SLA categories). It's still impressive to watch you pull it off though, and there's obviously a high level of skill and game knowledge required

as soon as he introduced "seam shots" and the thumbnail being about sensitivity, i had a hunch it was about ropz's sens thing, and man was i right. that's amazing that something like a pro csgo player's discovery can even affect the portal speedrun meta, crazy.

[@ThePsyphil]

They should probably just ban changing sensitivity and dpi during a run

[@renakunisaki]

And using the dev console.

[@clairevoyanceSLA]

@@renakunisaki use of dev console allows for a lot of qol and such which is accepted by the community as legitimate, and disallowing it’s use entirely would be pointless (since pretty much everyone is fine with dev console anyway) and impossible to incorporate considering how commonplace it is and has been for years in runs.

[@brynshannon6692]

Okay, if I knew an aiming training thing like the blue ball targets existed, I'd probably have used it... instead of growing a distaste for FPSs over a decade ago and wussing out towards melee-oriented games instead. X'D (crying inside)

[@ruinenlust_]

How can someone adjust their sensitivity on the run? Why did you not explain this?

[@finx10097]

macros, clipboard pastes ready for the console, basically any way you can think of normally changing your mouse sens???????

[@ruinenlust_]

@@finx10097 how is that not cheating. seriously. you're setting the value using a console because the game wouldn't normally allow you to do so. that's what we call cheating.

[@mythicalgod]

@@ruinenlust_ In source engine games you have "sv_cheats", which basically turns cheats on and allows cheat commands. With it turned off (by default), it only allows commands that were not considered cheats by developers.

[@ruinenlust_]

@@mythicalgod You understand that I, as someone who's not familiar with all this, saw this video and was confused right? It even says no cheating in the title but lo and behold it uses console commands. To me it still seems like cheating. Weird rule.

[@finx10097]

@@ruinenlust_ ok so they also aren't allowed to manually line up the seam shots because they use the pos values screen that have to be enabled via console? Like where's your logic? They pressed the console key so it must be a cheat. Also this is used for OOB speedruns which is also not intended by the Devs for you to be able to do, so the whole category is invalid because they're cheating?

[@Robertkopp84]

Finally a video about something I was pointing out for more than 20 years and everybody said I was stupid. I was just playing around with dpi and sensitivity in times where every 'pro player' told you 400 dpi is the best. Well when I set my razer copperhead mouse to 400 it was more like 300 and when you then try to go up to sensitivity 7 or 8 you will clearly see it. In HL1 or CS1.6 it skips 3 or 4 millimeters.

really disappointed to hear you use the word "spaz" in this. I'm sure you didn't mean any harm (and I know a lot of americans in particular seem to be unaware of this for some reason) but it's a really harmful ableist slur. yes, even in a non-derogatory context.

Next you're gonna tell me we can't use the word “slope” to describe an incline, because 60 years ago, our grandparents were using it as a racial slur? Get over yourself.

Spaz isn't a slur in America, it just means to be a klutz. Kind of like how "fanny" refers someone's butt in the U.S., but is a synonym for vagina in other former British colonies.

[@chluff]

@@hellterminator if you want to use ableist slurs just because you exist in an environment in which they are considered acceptable, that's up to you. but the vague hand-waving of "languages evolve" is just a post-hoc justification. it simply *is* a slur - what you want to do with that information is up to you.

This grid thing kinda explains why when you actually see cursor in the middle of screen it shakes and returns to center while your view in game shows you are looki ng around. I wonder if the distance the cursor travels before snapping back to center is affected by set sensitivity in game.
