Theoretically this could solve a lot of floating point issues in games that do not use a 'moving origin' already

First its working computers in Minecraft now its quantum physics in source

So what you've implimented here is an established gamedev technique called a "floating origin". All open world games do it in some capacity to avoid floating precision artificats, however multiplayer games do it differently. Everything that happens on the server is stored in double precision and exsists "in their real position". Its only on the client where everything is converted to floats in order to speed up rendering and thus requires a *local* floating origin. Having the telleports happen on the server as well is something we *desperatly* try to avoid, however it seems you've got a really good system working with masking out the collisions and wrapping everyone back around on the server as well. Very impressive system.

i visualized this method, but i never thought anyone would actually do it in gmod. good stuff

This is awesome! You did a great job! I create maps since my childhood in Warcraft 3 as a hobby, and a year ago I created a prototype of a coop map for multiple players that uses the very same method that you described. So basically my map is infinite. I created another set of coordinates and data storage for this. When players leave chunk - I save all parameters of objects that are left behind (2 sets of coordinates, type of object, life, etc.) and delete objects. But when players come back I create those objects back and restore their parameters, so players will see those objects again. My method is more primitive than yours because the players on my map always stay close to each other. There is an explanation for this - all the players on the board of the spaceship. And the spaceship itself moves between the chunks. Players take on the role of its crew and can only move inside the ship, or if they use a shuttle to only fly nearby. Still, you did an amazing job. Thank you for the new ideas and for the proof that this is a good method.

The creators of the localized physics tool made a map called gm_infinigrass a while back that used a similar technique. I remember it being really buggy, but quite fun

I love how much you explain things for everybody, not Gmod map maker experts, you explain for EVERYBODY.

That bit where you need to create a duplicate object to ensure collision works across boundaries has actually been done in source before; portal uses that system to allow collisions through portals! There's a hidden entity called physicsshadowclone that acts as a secondary hitbox before the object has reached reached the other side!

Mirror mirror on the wall, who will be the earliest of them all? Edit: I just watched the entire explanation, really cool and easy to understand explanation

I do remember a gravity hull mod that also allowed for infinite maps, but it had the issue of not isolating the players properly, and the physgun glow was still rendered where the players really were. I do also remember that it had limited random generation support if I recall correctly, and the gravity hulls worked in a similar way to the Safe Space addon. lots of source trickery, which is always cool to see :P

This is sick. Can't wait to see what people do with this. By the way, you can change the far z during the map creation process.

It would've been hilarious if at 1:07 when you said "it's legitimately impossible to go past the hammer map size", you followed it up with "anyways..." and then walked past it XD

This is super cool, though if I understand correctly then when it comes to making detailed maps bigger than a normal source map you're still limited to the original size, so you'll have the same repeating map over and over and over and over, so the best you could do is an infinite flatgrass. I guess you could solve it if it were possible to superimpose objects in hammer and make them appear only on depending chunk coordinates, maybe something like that could be done with only props

I imagine the only way to make "terrain" past the chunk boundaries is with props, so are you gonna try combining your terrain tool with this when you get it all working correctly?

immediately after i said i had no idea what chunks were in gmod, he uploads this vid, nice.

This was a good explanation, it's just a bunch of layers sitting in the same chunk, but with a little math and visual magic you can make it look like it's on a grid. You could also probably do this up and down, which is a cool concept.

Does 3D skybox have the same render distance limit? It makes everything look 16x bigger, so, perhaps, it might be a way to essentially multiply the default far Z value by 16?

You should do a video where you allow multiple people to try it out on a server (If it's possible/works in multiplayer). See what kind of concepts or ideas people can make out of this. By using and testing it it's limits

I actually had proposed the exact concept to my friend Its gonna be neat to see if contraptions can withstand the teleport

So it's kind of like how super mario 64's "parallel universes" work, so one question I have is what is the current map you're using? Is it just a sky map? Would a flat water only map work too?

It is awesome seeing you work on any project, and even cooler to see some techniques/ideas thrown in to help new projects turn out smoother

This is extremely smart! The simplest wat to put it is that its like going into the upside down in stranger things. It is 2 places merged but not visible or interactive

Dude you have like the biggest brain ever, your idea is incredible P.s. If I understand it correctly the explosions and bullets will do all sorts of whacky things

Nice explanation, didn't realise how small hammer maps were. This addon seems like it'll be very useful!

We do it somewhat similar, have a specific position on the map to store objects physical state (but invisible) and store all other data on server itself and handle everything that way(everything is fake in sense but from stored data there are comparisons to be made that allow it to function), for shots we also do a TraceRay onto compensated position and match it within entity bounds so the hitbox wouldnt be off and that the fake location wouldn't be accidentally hittable, still trying to figure out sounds properly seems like it's better to just tell clients to play sound locally but haven't tested much with directions Also if you apply damage via serverside don't forget to add some sort of directional weak knockback as well cause it looks odd otherwise during pvp sessions. By messing around with sending data to players we seem to have managed to cause nullpointers on multiple cheats that don't have much sanity checks, so that's funny, but never reliable of course.

I found this out while toying with bombs on some infinit maps and now I know I was right thank you

warning: there is alot of things to read in this comment and can cause confusion, misunderstanding and bad engelish can't you make it so your playermodel is smaller so there is alot more space but keep the chunks and have some sort of way to make textures "smaller" but not in resolution. this would make it feel even more infinite. make the chunks about half of the size of the map. so it gives you some sort of space idk. if you arr planning on adding this to other maps or even a way as a mod make it infinite for every gmod addon map. make it so your player doesn't clip through any of the walls and if the ground is lower or higher from the ground make sure it does not teleport players above or below the map and teleport them to a space where they can walk without any issues. it's confusing to tell what i mean but something with smaller player, bigger chunks, addon map support, don't tp player underneath or overneath the map you were playing on, tp player to a lower/higher space if the space on the otherside of the map is in a lower or higher altitude (sorry for my bad engelish) and teleport player to a suiteable place where you can walk and not get tped into a wall. my last thing i want you to add is if you are playing on a backrooms map or something like that. make it so the enviroment the player is in without an outside has endless rooms and hallways edit: make it so it's like a randomly generated backrooms map, like a script where it generates rooms based on the rooms from the previous chunk.. unload previous chunk however keep the previous chunk but with only portions that are visible from the next chunk. ray cast only the part that are visible from the other chunk so it doesn't look like an empty space when you enter the other chunk. idk how to describe it. what i try to say is like an infinite but random generated map themed chunks for indoor maps edit edit: make another addon for randomly generated but also infinite maps and for out doors maps make it infinite but randomly generated chunks with same theme as the first chunk however it's completely different and creates as an example: if the map is some sort of hills or whatever it generates chunks in that theme but it's differently. it generates suiteable chunks that fit with the actual map theme.

This is genius. You are very talented, my friend.

9:38 Cat meow moment.

i dont know much about g mod but this is actualy really intresting info. gives me ideas for other things.

Holy shit, this is like how game makers found shortcuts and stuff to push old consoles to the limit

The small map size in Gmod was the main reason I was looking forward to S&box, but now that that issue has been resolved, the possibilities are limitless! People can RP on a real GTA style map! Spaceships flying through fast expanses, planet to planet! All of those Wind Waker maps could finally be combined! You could have 50 people all playing in VR on a map the size of Skyrim!

what a maaagic. btw, you can cut the ummm eeeeem ummm part in the editor, so more people would understand you, I guess. but I like it even with ummm eeeeem

wait this is really cool. Good job with working on this

i thought youbwere gonna say "hello everyone, this is your daily dose of internet" for a second

My brain hurts from the chunk explanation

Mee is just a bored omnipotent source god at this point lol

LOL I came up with the same method 2 months ago for my own engine project, I think it'll work great aside from NPCs deactivating outside the 9 loaded chunks

What about NPC pathfinding, do they go to the player's rendered position as supposed to or do they go to the player's legitimate position (npcs do not exit centre chunk)?

I have two questions, can this work with the Zeta players and other nextbots like Drg and 2D Sanic clones, and with vehicles (WAC, LFS, Simfphys etc.)? PS: The explanation is grate, and the visuals are clever.

man plays with dolls for 7-8 minutes explaining a complex concept

Cute little teeny tiny baby props

This is just brilliant. Very impressive!

Great implementation. I think I could take a swing at animating this explanation. Your visual aids were pretty good tho!

But first, we need to talk about parallel universes.

This reminds me of the summoning salt video of super Mario 64 when there’s this glitch to go super fast and teleport to another copy dimension in the game

started up this video and thought i was watching a khan academy video or something with the way you talked

This sounds like the whole parallel universes thing in Mario 64.

Well explained, nice concept too!

for the first second i thought i was watching a garbaj video lol

this is amazing, i need this

Another way to explain would be to show actual entities in wireframe material clicking back as they travel away from a player

G Bombs is gonna even more fun now

every boundry is like another dimension. like w,x,y,z where w is a different layer. x,y when escaping the max or minimum limits you get it kind of flipped in a way while updating w to which ever chunk you're in. but the problem is intersecting objects with chunk borders so he duplicates it to make it. the issue i see is bigger maps, map chunks, weapons, vehicles and physics props.

imagine this man making source 2 on source 1 with gmod

Since portals work on this map, Tardi should as well, other than the possibility of the tardis not loading when it's to far

The center "main" chunk can actually be much larger. You only need the other chunks to occupy a tiny fringe of the map in order for the teleport trigger to be hit, if you get creative with rendering

i would love to see like farlands reference after walking like 10 hours straight in one direction lol

The visuals and explanation remind me of Pannen's explanation of PUs in SM64

So essentially, geocentrism has been implemented in gmod.

oh this is very clever good job my dude!

wow, that's pretty useful

this must have been a headache to design, nonetheless put into practice. huge props.

bros a gmod scientist but man youre great

I've been dreaming of creating a map where I could fly a plane in a straight line without having to turn erratically for 2 years, hopefully that dream will come true.

we definitely live in a simulation

Cool

This is so cool I wish I could play on a map like that!

sooo.. essentially you could have a ship addon like a spaceship or a TARDIS let's say , assuming they'd add auto-pilot to fly forwards while you're walking around, you could make infinite space to fly through? that's mad

this guy made kerbal space program in gmod

Do raycasts properly go between chunks? like can you shoot a weapon from one chunk into another?

this is fucking insane

you are a god damned genius. why the hell didn't the actual devs think about this. unless of course that wasn't their goal all along, but rather to make the canvas in the first place. still very inspiring and informative. i'm little more than half way through watching the video but wanna get the complement out of my system before i forget.

you are awesome man

4D space, i get it 💯

This is groundbreaking

hello everyone garbaj here 0:00

Hey uh question regarding the map (seriously) You ever played daggerfall?

in s&box they also made it posible but with edeting source 2 sourcecode

man visualizes expert coding skills inside of gmod, breaking news

what about weapons, i believe the revolver is hit-scan, how'd that work, or the crossbow, which i believe has a physical bullet. let's say you for example shoot the rendered enemy which has teleported to the other side, wouldn't that brake the hit-scan, with the crossbow, lets say it works but in front of the invisible real version of the enemy there is another one visible, wouldn't that make the crossbow hit the wrong target?

so basically one chunk houses the entire world

Now you just have to wait to get a job at Valve

Very interesting

Can a player in chunk 1 accidentally destroy a breakable object in chunk 2 if they're in the same "technical" location?

please stop bullying our game engine, thank u. -Valve Team

normal people: this idea would be hard to do in source... I guess I will do something in roblox or unity or whatever.. Mee: this would be hard to do in source... well, time to learn literar magic and fuck around on the very edges of the engine limitations.

I played something similar to this on GMod where a map is basically one infinitely going flat grassland. You can't really drive vehicles past a certain point as an invisible wall will stop it in its tracks while you're driving it, though. Which begs the question... do props despawn when you go far enough from the "center origin" of the map?

I cant be the only one who thinks this person sounds like the youtuber Garbaj...

instead of using a paint tool to show 2d chunks the absolute madman made it in hammer and presented it in gmod. lmao!

I understood it, but it is probably because I'm a programmer myself, but yeah nice trick

whats crazy is that its modded with probably lua into a game with limitations thats based on source with limitations

that's cool

I understand correctly that this has a lot of problems with collision detection, shots, lighting, mechanisms?

9:37 meaaaaaoowwww

Pretty sure if you turn on sv cheats, change a variable and then turn sv cheats off on the same tick, the server basically won't "notice" that cheats were turned on (ie achievements still work and everything). At least that's the case in TF2, but i don't see why it would be any different in GMod.

based video

so does it just store the perceived offset from the world origin for each object in an array, and then iterate through that to offset the rendering each frame? very very cool stuff, excited to see final product

how do hitboxes work? if someone goes far away can you still shoot them? and what about explosions? if you took a bomb far away would it damage everything because it is technically still in the center chunk with everything else?

that's so cool oh my god
