How Holding Objects Really Works

I explain how holding objects really works in SM64. Here is a complete summary:
When Mario grabs at an object and appears to hold it, it's actually just a clever illusion. The object instead becomes invisible and intangible, in state called "limbo". In limbo, the object won't interact with or influence anything in the real world. Simultaneously when the object is sent to limbo, Mario's given a "ticket" that looks exactly like the object he grabbed at. Furthermore, when Mario releases the ticket, the object will come back from limbo to the real world on the same frame the ticket disappears. And so, since the ticket appears right when the object is sent to limbo, and since the object comes back from limbo right when the ticket disappears, it creates the illusion that the ticket IS the object, but that's false.
Since the ticket is its own entity separate from the object, it needs its own coordinates to render at. Thus, the HOLP is a variable specifically designed to be where the ticket renders. The HOLP is used as the bridge for the transition from ticket to object, since the object needs to know where to appear in the real world so as to maintain the illusion that the ticket was the object. If Mario throws the ticket, the object appears at the HOLP but translated 32 units forward in Mario's facing direction. If Mario drops the ticket, the object appears at the HOLP laterally but at Mario's current height. More info on this here: • Releasing Objects . Additionally, if the ticket doesn't render because of any number of glitches, then the HOLP simply won't bother to update. We can take advantage of this by having the object transition back to the real world at an old HOLP value.
Cloning is a glitch where we grab at an object and it unloads after the grab is established (frame 3) but before the object is sent to limbo (frame 6). Since unloaded objects aren't processed, the object is never sent to limbo, and so Mario ends up with a ticket for an object not in limbo. The whole point of sending objects to limbo is to keep them safe and inactive so they won't unload while we're supposedly holding them. But since this doesn't happen, any object can now load into the slot represented by the ticket, and so it will appear as though Mario is holding those objects.
Handsfree teleporting is a glitch where Mario teleports while holding a ticket. Unlike all other ways of releasing a ticket, this way doesn't redeem the ticket, but instead discards the ticket without affecting the corresponding object. Consequently, the object remains in limbo, but Mario no longer has its ticket. Thus, Mario becomes unable to retrieve the object from limbo and it's stuck there forever.
However, the exception to this is bob-bombs, since bob-ombs are unique in that they remain tangible in limbo. Consequently, bob-ombs can be manually grabbed straight out of limbo. The bob-bombs' tangibility in limbo also explains many bob-omb-related idiosyncrasies, such as why Mario can push goombas and detonate other bob-ombs while holding a bob-omb. It also explains why Mario experiences backwards momentum while holding a bloated bob-omb,
since the bob-omb's bloated hitbox is large enough so that it overlaps with Mario's hitbox. Hence, the bob-omb's hitbox will push Mario back, then update close to Mario again, then push Mario back, then update close to Mario again, and this repeats. The result is that Mario experiences constant backwards momentum.
P.S. The word "limbo" is defined as:
- a place or state of oblivion to which persons or things are regarded as being relegated when cast aside, forgotten, past, or out of date
- an intermediate, transitional, or midway state or place
- a place or state of imprisonment or confinement
Hence, it seemed like a fitting name to describe the realm that held objects are confined to as they wait for Mario to release the ticket so that they may return to the real world
Corrections:
(1) I said the grab is established on frame 3 of the grab, but it's actually established on frames 4 and 5. My mistake.

So you're just working your day job at the dry cleaners. Then, a plump Italian plumber walks through the door, wearing a red shirt and cap and blue overalls. For all the time you've worked there, this is the first time you've seen him. Then, he asks, "May I get-a my brother's clothes?" You instinctively reply, "May I see your ticket, sir?" Realizing his "mistake," he checks his pockets and states, "It seems that I have lost-a my ticket. But watch-a this." The man then holds out his arms as if he were holding something, steps in place a few times, and then throws the "object." The clothes that he asked for immediately appear, like some kind of magic trick. The man then says, "See you next time." He backs up against the wall near the door and begins jumping in a strange manner. Moments later, he starts spasming against the wall, and then disappears in an instant.

Fun fact: When chuckya grabs Mario he does the same thing. He gets a ticket and Mario is sent into Limbo. You can see that by walking in front of a bob-omb first. The bob-omb will then walk towards Mario and if Mario is then grabbed by a chuckya the bob-omb will still run towards the place where Mario was grabbed.

This video made me afraid to lose my ticket if I ever end up using one of these coat stations, so I think I won't.

[@BradenBest]

Actually, the first thing I thought of when you said the object becomes invisible and intangible is Minecraft's _FallingSand_ entity. Except FallingSand is a single entity that can be skinned to look like any block, can have its physics turned on or off, and during normal gameplay, it actually destroys/creates the sand (or gravel) that it masquerades as if the game's physics determines that the block can "fall" (sand can fall? -> destroy sand at (X1, Y1, Z1) -> spawn fallingsand at (X1, Y1, Z1) -> hit block? -> kill fallingsand at (X2, Y2, Z2) -> create sand at (X2, Y2, Z2)). I say "determine" because there are plenty of optimization-bourne in-game bugs that can prevent sand from falling by tricking the game into thinking that either there's something below a block of sand, or that it doesn't need to check that block for some reason (block updates). Beyond that, FallingSand is generally just plain glitchy. For example, if you put a piston under a pillar of 14 blocks of sand, and arrange it to rapidly move up and down, you'll _lose sand_.

[@SuperNuclearBoss]

Braden Best SethBling could use command blocks to create a custom entity: *_Walking Sand_*

[@SuperNuclearBoss]

Replace a walking entity with a FallingSand entity boom

Two main things I want to say about this video. The first is that for as "silly" as some may say the coatroom comparison was, it actually made a lot of sense to me, and I liked how easily comprehensible it was. The other is that if Mario really does have the power to transport things to and from some sort of "limbo", the guys over at Death Battle may have made a huge oversight.

[@Lizuma]

Wow thanks so much for this amazing video!! I LOVED IT!! I NEVER KNEW that was how holding objects worked until now!! I always thought it was the real object being picked up! I wonder if other Super Mario games with picking up objects, including the ds version of sm64, do this! The explanations were great, I was able to understand everything you were talking about!

[@tripplordofinconvenience9953]

Here’s something interesting I found in Super Mario 64: in Shifting Sand Land the yellow box that contains a shell on the roof of the structure near the start of the level makes sand particles appear when you walk on top of it. I don’t know if it’s supposed to do that or not.

[@ShadowAbomination]

I've always wondered how speedrunners did the Chain Chomp star without opening the gate, and this explains part of it! The increased Bobomb hitbox pushes Mario backwards, and he collides with the gate, probably in a particular way that takes advantage of the wall hitboxes being projected in cardinal directions, and so Mario pops on through!

[@MarioDSLife]

Then you’re given a ticket that represents your ownership of the coat...” Oh. I see. “Later when you want your coat back, you can redeem the ticket and your coat will be returned to you.” 👌🏻.

[@Goretantath]

i like how the frame comparisons were timed to the walking sfx x3

[@GraveUypo]

these videos are so awesome.

[@adamblakeslee5301]

I actually did something similar in Unreal once for a school project. The idea was that I wanted the player to collect wheels and attach them to a car but with time being an issue, I created two sets of wheels, one on the car and one scattered around the level. Each time the player touched a wheel scattered around the level, the wheel would go invisible (it was always intangible) and a switch would be flipped. The car already had a set of wheels but they were invisible and when when the player touched the car, one of the wheels would become visible for every switch that was flipped. So without ever giving the player an inventory, I had given them the ability to collect items. The key to good game design is to give the illusion of what should happen while you go off and set things up to be as simple and easy to make as possible.

[@WhimsyHeath]

One question: When object is in limbo and we don't have the ticket, what if there is a way to get a ticket for example of object 30, then unload the object in limbo somehow and/or change its ID to 30 and have the ticket of the object back? Or maybe a way to get a ticket with ID 30 from other source? Or maybe take ticket and change it's ID by wanking the game's memory by lots of objects? Or something else like that? (nvm, 3 questions lol)

[@UncommentatedPannen]

You'll have a ticket for a different slot. You can change what object is in that slot, but you can't change which slot the ticket references. So there's no way to recover it

[@Architector_4]

pannenkeok2012 Okay then. _(insert hype responce)_

[@jongyon7192p]

You can choose the slot by grabbing an object from that slot, right? So since the limbo object will stay in its slot, the only way to grab the slot is to grab the limbo object itself, right? What if you grab the limbo bobomb fake? Wait is that even possible? I need to look back on how to clone again.

[@shadowj2381]

I always thought it was when Mario grabs something or plays the animation of grabbing as near movable checkpoints ex cork box as a checkpoint he will grab the nearest object or model and use that. And since the nearest object is the object you want to grab its the first thing that teleports to mario's hands is the movable checkpoint and made me think of the bobomb glitch causes Mario to grab an nonexistent object which keeps him in the state of trying to find an object to grab so when he goes to the nearest object it's teleported to mario's hands

[@Microraptorgui]

When I first played Super Mario 64 in 1996, I noticed that grabbing an object while Mario was already holding his hat would cause the object to vanish, and that trying to put it down or throw it would cause it to reappear in an abnormal location. But for the past twenty years, I never saw that glitch being discussed by anyone else. This video (specifically 4:10) is the first time I've seen an explanation for why it happens.

[@groszak1]

[@williamgabriel2245]

So um... I heard you have a cork box. Can I touch it Mario: Well, technically, this isn't the real cork box, just a visual representation to show that I am the owner of the cork box. So, Mario invented NFTs before everyone else.

[@lilscranton6897]

The non-throwable limbo objects update with Mario My guess is having it in the same place it was picked up would require it to be teleported, but having it update with Mario means you can just say "have object go down x units"

[@alphamoonman]

I feel like your videos on all this stuff is a cheatsheet for beginner coders devising logic to engines.

[@yoshibros1111]

I found out something, chuckya also has a holp and when you change chuckyas graphics to Mario's using stroop it will no longer update. Don't know if this is useful but worth looking into. I believe this is also why the camera behaves so weird when being picked up. I'm not sure about king bobomb but I suspect the results with it will be similar.

[@FEScarf]

+Brody Read easier to program / less work to do i assume, thats the reason why many of these glitches are around

This system was a design choice, and I don't know exactly why they chose to do it this way. Perhaps it was easier because the ticket has no hitbox so it doesn't harm/affect anything. For example, if they put the actual object in front of Mario, they'd have to specially disable many of its properties, such as its collision with walls, its collision with Mario, etc. The ticket just goes through walls and Mario, so they wouldn't have to worry about that. And yes, the HOLP is a result of the object-ticket system. If they had implemented it differently, they probably wouldn't have needed a HOLP value.

+Brody Read As mentioned in the video, the point of the limbo is to make sure Mario’s held object is treated as such, e.g. so that a held cork box doesn’t despawn after 30 seconds. It could probably be done by having a “held” flag in each object and accounting for it in the object’s behavior, but it would take more time and memory. That being said, that solution would probably remove the need for storing a HOLP value, as the object itself would move with Mario. Old games do a lot of things that you wouldn’t do nowadays in terms of programming; for example, updating the HOLP seems to require rendering the held object, which is terrible because it means any graphical glitch (like the hat in hand glitch, or the newfound ways to get the game to not render Mario) will immediately cascade into glitches with an actual impact on the gameplay. The main focus for programmers used to be optimization because of the limited memory and CPU, but now it’s more about separating concerns in order to make the code easier to maintain and avoid cases like that where a minor flaw can break everything.

+pannenkeok2012 Not to mention this simplifies the Bob-Omb situation, where they _want_ the object to have a hitbox _and_ render very close to Mario. By separating the held object's rendering from its physical existence, this becomes possible without having to add "if you're held by Mario, don't check collisions with Mario, but still check collisions with other objects. If you _are_ Mario, and you're holding something, don't check collisions with it, but still check collisions with other objects." to the physics engine. That improves performance in the general case. Sure, the game has to do a little more work when Mario grabs or releases an object, and while rendering a held object, but _no other object_ has to care about all that. Contrast with the alternative, where objects need to check what Mario's holding on every collision, even if Mario isn't actually holding anything. The entire HOLP/ticket system might be an idiosyncrasy spawned by the decision to add liftable-yet-collidable Bob-Ombs to the game. And considering the first level of the game, that decision was probably made early-on. While I'm throwing around -baseless speculation- -educated guesses- ideas, if they didn't go with the ticket system at all, cloning most likely would not be possible either, because Mario could hold real objects instead of references to object slots. In short, if BBB weren't a thing, ABC might not be either.

Any clues on why they decided to make this whole "limbo" thing in the first place instead of just having the real object move with you?

[@TheVercci]

Are you planning some big reveal soon? You're coming out with a lot of mechanic focused videos I can't help but think they're going to be used as a reference.

[@UncommentatedPannen]

No, I'm documenting everything I've learned/figured out/realized over the past several weeks, since I'm now on spring break and have free time to do so. At the current moment, I just finished catching up with everything.

11:34 Does the kick's hitbox extend far enough to let you hit things by running into them that way?
