Iron Bomber guy here, the barrels were designed to rotate but because of the way they're positioned (and because there are only 4 of them instead of 6), there is no way to rig them to rotate when firing as far as I know, so I cheated. The barrels are rigged to an extra bone that isn't present in the stock grenade launcher, and the footage from the demonstration video is actually from Garry's Mod and not TF2. I was working on a personal project which aimed to replicate TF2 in Garry's Mod at the time, so all the code for the grenade launcher was already present, all I had to do was add a bit of extra code to make the barrels spin after every shot. It would be possible to do that in TF2 in theory, but it would be hard to implement in a way that doesn't result in a hacky mess and I never expected Valve to go that far just for a single weapon, it was just a fun little experiment I wanted to show off in the video.

Those aren’t bugs, that’s just Demoman drinking too much scrumpy all at once

We actually discovered late last night that the Splendid Screen bug at 11:07 only occurs if it's changed off the default style! If it's in the default style it will show up. Weird.

Spy so buggy he gets a feature in the Demo video!

The floating shield bug appears to only happen in servers with tournament mode enabled (mp_tournament 1). This also includes Casual mode, which uses a modified tournament mode. It is a derivative of competitive mode, after all. Community servers tend to not use tournament mode, so the bug won't show on those servers. Also, here's an annoying one. Sometimes when your charge ends early (via shield bash, I believe), the minicrit particles and sfx will remain indefinitely until you charge again. The sfx even persists through dying, respawns and class changes. You could do snd_restart in console to stop the sounds but that won't fix the minicrit particle effects, which only go away by charging or perhaps switching class. Sometimes I intentionally have to wait an extra cooldown outside of combat because of this bug.

18:53 - For what it's worth, at least in the context of doing it with the high-five taunt, you _are_ still providing a "smiling face," as the achievement says, just not the drawn one

I want to see some engineer bugs next! I bet he's got some fun ones.

Damn, even Demoman's weapons are drunk. This is getting out of hand.

3:20 Demoman holding a knife isn't something I thought I wanted to see, but I'm glad to have seen it

gosh imagine hitting an ennemy with your pipe that bounced of your teamate. must be the hypest thing ever

In fact, I saw this bug with flying shield that can be seen through walls a few weeks ago. I think this bug is just very rare

aww, what's that? the iron bomber is a straight upgrade? awww

They didn't just give demoman a glock, they gave him a whole ass minigun.

3:57 With what I remember from History Class, it was noted during the civil war that cannonballs could gib the poor souls unlucky enough to be in the way, so I consider this an intentional effect.

Another way to do the broken caber glitch is to hit a retracting spawn door.

What a nice class, hopefully it isn't bugged to the point it's absurd that it's state is even accepted by valve

My guess with the mini crit bottle bug is that the client goes 'it broke' and swaps the model and the server goes 'nuh-uh, that was a mini crit' so the client fixes it.

3:10. WE CAN FINALLY GIVE DEMOMAN A GLOCK!

There's also the bug where Demoman's extended sword range during charges only work for Demo robots. For players, the extended range only works while charging, which ends the moment you swing. However, Solarlight found out that if you swing right before beginning the charge (therefore not canceling the charge), you will get a regular damage, yet extended swing.

Not sure if it's specifically a spectator mode thing but I have experienced the floating shield issue before multiple times fairly recently

17:07 might be referring to the end screen of casual or competitive where the scoreboard gets brought up. Sometimes the sounds relating to sticky jumping keep playing even after I lose control of my character, which might then count the airtime or something? Food for thought.

The bug at 10:30 still exists, you need to use a sword so the shield appears in first person

Ah yes, what is scarier than a charging Scottish Cyclops with a haunted sword? *A charging Scottish Cyclops with a minigun*

It's funny how many of the demoknight bugs clearly came from the solarlight videos about Demo bugs, but they didn't copy all of them. The Extender bug where you can boost melee range while charging is apparently not on the wiki.

For the bug at 17:02, I think it may be referring to the payload explosion throwing you just as the round ends.

10:15 Xmas lights: ELECTRICITY, POWER!, INFINITE POWER!

The "seeing ur shield after death" bug is real, I still see it when I die

6:56 PLEASE TRY DOING THIS ON AN ENTIRE ENEMY DEMOMENS TEAMS WORT OF STICY BOMBS (The plual of Demoman is Demomen)

4:03 to be fair people irl don’t stay in one piece when hit with cannon balls

Loch and Load bouncing pipes is gold

"The cannon ball doesn't explode on impact." Definitely, absolutely.

3:50 Your class model on the right is holding the degreaser, whereas you are holding the stock flamethrower. Just pointing that out.

10:21 I've only ever seen this one happen with the tide turner, maybe it's been fixed on the other shields? I don't know.

4:48 boy did this bug age like a fine wine

the bug at 17:02 is real! if you are on the winning team and inside of your spawn as the round ends, you are teleported to the enemy spawn. if you stickyjump before you're teleported, it counts the distance from your spawn to the enemies spawn, thereby giving you the achievement.

10:40 yes it's still does, me and my friends were playing the community mvm campaign today and we all were demoknights (doing the FUNNY) and it was bound to happen... You can imagine our faces trying to understand half a dozen Shields scattered throughout the map

I gotta say good on you for still managing to find original video ideas for this game lol. Also I feel as though engie would have some fun bugs

ive always thought that the loose cannon gibbing players with low health was a feature ig you learn something new everyday

For the highland fling achievement... Depending on how early that bug was added to the wiki, it might be referring to a server changing maps. When a map ends and the server prepares to change maps, every player is frozen - and I think that might include in midair too. And while you're frozen, it might be theoretically possible to gain the highland fling achievement.

I remember submitting one for Sniper when I played MvM and noticed Spies can just pierce through the Razorback. Looking back at it, I think it is due to the Robot Spy having an infinite swing speed.

Ngl I kinda want the stock grenade launcher to also get the increased hit box rather than fixing the bomber's

14:06 I personally love this glitch, especially if it is used with the bumper car.

1:42 Catboy Demo doesnt exist he can't hurt you. Catboy Demo

The weird properties in Nucleus' point come from the fact that the entire platform is a dynamic prop, not a static prop or brush. This also causes ragdolls and gibs to fall through the platform. The same behavior occurs on the payload cart and other things.

That floating shield bug can be fixed by doing "cl_first_person_uses_world_model 1; wait 10; cl_first_person_uses_world_model 0" Bind it to a key so you can do that when you need to bind [KEY] "cl_first_person_uses_world_model 1; wait 10; cl_first_person_uses_world_model 0"

0:48 mom get the camrea

17:26 they were talking about the crit boost the winning team gets, making you able to get the achievement with the sticky jumper but due to crit boost you can jump way further

The beckoning Demoman is hilarious

13:08 I can also confirm this still happens (pretty randomly tho), I regularly use the caber.

Your ad segment actually feels pretty genuine

The collision less shield bug has happened to me quite a bit in the past few months, it does still exist

worth noting: You can also get the second eye using a laughing taunt or when a holiday punch heavy crits you. Least that's how I got it by complete accident

10:25 this bug still happens from time to time but from my experience it's very rare

RIP Iron Bomber 2014 - 2022 😭🥺😢

Oh yeah, for the floating shield bug, I have a similar bug that I've seen a lot where, when you're spectating somebody swimming, if you un-specatate them (for example, when you respawn), it will for a short while show splashing around yourself in first person view. At the very least, I've seen this happen a few times on lakeside.

Oh god, another one, thank the gods,. I love these videos

This video is a year old, but I think that the glitch with the Highland Fling achievement is about starting the jump right before the map changes at the end of a round, meaning that the game will recognize that you somehow jumped from one map to the next.

Probably the best way to get this to you. I believe the bug at 16:58 is saying that if you jump after the round ends, and are teleported back to base while still in the air, you should get the acheivement.

Demoman with a minigun, demoman has enought

Here's one I found recently. The sticky jumper's shooting sound will become the stock's shooting sound after a round ends (like after the last point is capped)

For the U turn achievement, I believe they might be saying you can kill an enemy by charging and detonating a sticky bomb on an enemy behind a wall that you can't currently see. But I think that's probably not a bug either.

I think the reason why the Rocket Jumper doesn't make pumpkin bombs explodes is because once the projectile collides with something, it applies the knock back to you, and then removes the projectile before it collides with anything basically, when it collides with something, it removes itself so it doesn't collide with anything

Love your content man

I think the reason why you can't pick up beer bottles or the other collectibles in Player Destruction mode is that they are classified as intelligence in the game's code. This is why you can get the Belittled Beleaguer achievement on these maps.

fantastic work

as a demoknight main, yeah the floating shield bug does still happen. almost every game in fact, I don’t know what causes it but hey it makes it easier to see

I like to call the first bug that was listed, ‘the demo-lobster’

3:11 why does demoman always look badass with any weapon he's holding

1:34 ah yes, the spycrab's more aggressive cousin: the democrab

One unlisted bug: Frying pan Demo has infinite melee range.

15:05 the same thing happens with tide Turner+wee booties on kill and holding charge down

Whatever bug you're talking about in the intro, I think it might apply to the Box Trot taunt as well. I've been getting a red box on blue team an awful lot lately

Errors I noticed in the video: 17:05 I think this refers to multi-stage map that teleport you to the next spawn room at round end 18:02 you probably need to be charging for this to work. like you detonate the sticky mid-charge on an enemy you never saw 18:33 this isn't a bug because it says "The Grenade Launcher", not "a grenade launcher"

The bug of the shield not glowing from others' point of view is because in first person it is "attached" to the active weapon, while from another point of view it isn't and instead attached to the arm of demoman. The broken bottle effect from the tide turner is an "end of charge" animation i would guess, which is why when you have the swing timer reset it goes back to normal.

16:58 I think this bug may either talk about getting this achievement via enemy stickies specifically when the round ends, or just that you can get it by grenade jumping when the round ends like it said in the part you omitted.

This is the first tjme i didnt skip a sponsor segment and is willing to install the sponser lol

The floating shield bug goes back to 2014 actually. It’s in STAR’s “I main Demoknight 6v6” which is from March of 2014 I think

For the lock n load, it's while the Nucleus platform is extending. It's the dynamic part of the props that cause it to bounce. Guess it must be dynamic props or animated static props

The reason the sticky jumper can destroy pumpkin bombs but the rocket jumper can't is probably because the rocket jumper rockets don't explode on impact, and just disappear like normal rockets. The sticky jumper bombs collide with the pumpkins, triggering the explosion, just like hitting the pumpkin with any melee will trigger the explosion.

Return of the king

I think Demoman is one of the least buggy TF2 classes.

The bug where the shield floats in midair after spectating a player definitely still exists. I saw it last week on nucleus.

I was recently playing a Hightower game when the floating shield glitch showed up when I was demo panning

Honest the intro was basically me. I like the sound on keypress or whatever it's called.

The caber taunt is my favorite because I would always use the Scotsman's Stagger to make it look like Demo is drinking his own caber and it doesn't explode in his mouth

I really hope they fix the bug that causes the iron bomber barrel not to spin. It’s a minor thing, but that animation looks so damn cool.

3:30 - Sounds like an incorrect position offset is being used there. 4:56 - This is because the Iron Bomber has an attribute that replaces a model with a different one. The whole process causes a bounding box recalculation that the projectile type doesn't override due to the bounding box assignment coming before the projectile model change. The same attribute is also present on the Quickiebomb Launcher, and will only affect grenades and stickies. 5:38 - Yup, it's as it says. The barrel is not rigged to the correct bone, but to a different bone. 6:36 - My initial thinking was that this is because the Sticky Jumper projectile is under a different projectile ID as the Sticky Jumper uses an attribute called "override projectile type" for what it fires which means the function that handles stickies destroying other stickies was simply a case of projectile ID. I do not have the means to check if this actually the case though... 10:15 - This is simply a missing line in the material file. 14:21 - The Half-Zatoichi is a total mess in how it's shown. In the schema, it's "anim_class" key (which animation set to use in both first- and third-person. Scatterguns, Rocket Launchers, Flamethrowers and Miniguns all use "primary" for example) is simply blank and is assigned one in game. What you're seeing suggests that the Half-Zatoichi is using the "melee" animation set by default, and a series of conditions will force an override to the "item1" animation set - used by the Demoman for all his swords - if all are met.

Huh I actually happen to know of another achievement-related bug. I got the "Sticky Thump" achievement, which states: "using the Scottish Resistance, kill 3 players without placing new traps", while using the SBL. I even had a video of it.

For the highland fling, perhaps in humiliation the fact you've landed doesn't register and if you walk far enough, you get the achievement. That might be what it meant

12:07 yeah, when I use the tide turner and swing some melees at the end of the charge for a split second it will use the crit animation.

Maybe the highland fling achievement has something to do with payload explosions? Perhaps the game treats being launched from those as blast jumping?

2:56 I think that is more of a spy bug than demo.. But I'm not sure

I found a bug for the sield: If you start the uncrouch animations and essentially quantum crouch if you charge while doing it because your not able to crouch while charging. So this bugs the screen and causes it to violently shake up and down.

I actually have an explanation for the time turner bottle breaking bug, so way back when the tide turner was first released it was able to crit normally like all the other shields on a full charge, so I'm assuming the bottles are taking old code from the charge data off the tide turner, then are updating afterwards for the model, as the game realizes that you only dealt a minicrit and not a full crit.

My theory with the bottle breaking and restoring itself after a tide Turner charge is that the developers saw the old bug of it breaking and said "yeah you know what, we'll make it so the bottle restores itself after a tide turner charge, no one will notice" but didnt take into account the speed at which it is restored

1:35 - ya started with the Democrab! Ha-ha, classic! =)

Jim: demoman KZfaq captions: Haps Educatorman 14:34

11:07 I remember seeing this a few months ago but it was visible to someone else too. That person wasn't originally involved in the fight. They said they only saw it after they had a severe lagspike(packet loss) so it might have been something to do with that

Just like with the rocket jumper, the reason why you can't grab PD pickups with the sticky jumper is because PD pickups are the same flag entity as Intel, but with a specific setting for the mode.

If your team secures the intelligence while your engie is drinking beer, it shows him drinking the wrench and the bottle
