TF2 Bug Busters: Demoman Bugs

[@KilburnTheTweaker]

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.

[@weebnt_the_strong2458]

i believe the flouting sheald bug happens if the guy you are spectating has it equiped

[@SolarLight]

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.

If you see this bug, it can be fixed the same way invisible players (a client-side bug that makes other players completely unable to be seen and when you get killed by them, the kill cam will go to a part of the map that is not near you) and other visual bugs are fixed. I just can't remember how, I wanna say it has to do with starting and stopping a demo recording. I've had it bound to my ] key for so long I just can't remember what to put into console.

[@FurryWrecker911]

[@theoverpreparerlamenters3r436]

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

[@reiidaya4439]

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.

[@Appletank8]

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.

[@myriadtechrepair1191]

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.

[@Yuzzy1234]

It might also have to do with the fact that the tide turner used to crit

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.

[@medicindisquise4271]

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.

[@thegreenfox011]

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

[@GlitchyTypo]

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.

[@sopito9923]

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

[@Chaud31423]

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.

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.

10:59 I think the reason it wasn't working was because you cant normally see the with grenade launchers, the bug will work if you default to your melee

[@wojtekpolska1013]

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"

[@matteo-ciaramitaro]

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.

@@walugusgrudenburg3068 ya probably not. i was thinking they wouldn't disappear if you switched weapons but how do you detonate then?

[@internetmysteries1595]

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.

[@wojtekpolska1013]

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

[@noodlenogginsnogginonoodles]

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

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

[@Hypernova559x]

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.

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.

[@purplehaze2358]

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.

[@ohnoitspit]

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.

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.

Not sure if this counts as a bug or not but when the loose cannon is either crit or mini-crit boosted, it will be unable to double donk players and it prevents the dd counter from strange loose cannons to count as a dd.

[@angel89775]

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.
