I Made Sonic the Hedgehog but it's 3D 

A solution for when Sonic enters a tunnel: The terrain around him becomes transparent, except for the tunnel, and you can see Sonic rolling through it.

I like how at the end of the level, Sonic just ends it all

This looks very similar to the secret Green Hill level in Sonic Adventure 2 that you can unlock by getting all badges in all of the stages.

I’m the guy who made put this model on sketch fab… Thanks Cody! I changed my RU-vid account name to Goofy

Solution for ring lag: In the original games, sonic players will remember that if you get hit, you drop all your rings. They'll ALSO remember that the max ring drop limit is 20. So if you only have 4 rings you drop them all. But if you have 50 rings, sonic only drops 20 and the other 30 are gone.

"Green Hill Zone Act 1 is such an iconic stage, that even Sega decided to remake it in Generations." I think you're missing a couple hundred other games after Generations there

Maybe for the ring problem, you can turn off the hitbox for the rings and then just launch them in a random direction, but in the middle of their launch, turn on their hitbox so they can land on the ground

I like how sonic is unaware of the water ahead and just drowns no matter what

The first thing I noticed is that this controls more like Mario than Sonic. In a real Sonic game, Sonic would first have to build up speed for a few seconds before he goes really fast. This version is missing the Momentum which is important for every Sonic game.

I think this shows why the homing attack exists

The ring issue is simple, just set a rule where rings can't collide with other rings. When interacting with other rings just do the engine's version of the ignore collision function. Another option would be to script it so collision detection is enabled 200-500ms after spawn.

4:02 what you could've done is made the tunnel appear on the wall like the wall is invisible so you see Sonic running through it. It might even be with small transparrent squares similar to how in Mario Oddysey if something goes into the camera or if something gets too close

“The remade green hill lacked the 3d dimension” Green hill act 2 and sonic adventure 2 unlockable green hill: “am ima joke to u?

In most Sonic games, when he gets hit, no matter how many he had, he only drops 10-20 rings. If you could code that in, it would both be more accurate and save on resources

Wait what !That was amazing!Good work ! It's like sonic the hedgehog but it's 3d!

Every time I rewatch one of your videos you make me want to get back into blender

If the lag spike is being caused by the rings colliding with each other, you could probably just make it so the rings can't collide with each other, but can still collide with other objects.

When Sonic gets hurt, spawn a maximum of 20 rings or so. That's how it usually works in the games.

good job I really apricate this for such a interesting video and really hard work programming is hard

For the rings, You can make a limit of the amount of rings are spawned. For example if the limit was 30, even though there could be more than 30 rings on the counter the limit will spawn only 30 rings.

In Sonic Adventure 2's version of Green Hill, the tunnels look like they're carved into the wall and the camera automatically moves to a side-view when entering them. Maybe they can function similarly in this recreation.

There's actually a bonus stage in Sonic Adventure 2 that is exactly like this

Impressive, recommendation, having a bit of inspiration on the Sonic Adventure 2's layout one, just on stuff that couldve helped you visualize stuff. Impressive work still

I think the level should be made a bit bigger so that the loop looks more imposing and you can't just skip it easily that would also help with the speed issue.

I like how when sonic finishes, he just runs into the water

Ring problem: Assign the ring collision to its own physics layer, and then set that layer to not collide with other objects on the same layer. The rings won't check collisions with each other, only the world, sonic (and enemies if that's enabled too). Bam, collision issue solved ;) Pipe problem: You could make Sonic follow some path inside the pipes, and use a shader to show a semi-transparent Sonic through the world geometry. While this is happening, the camera animates around the terrain while looking at Sonic, sidestepping the camera-colliding-with-terrain issue (This tends to be what the official Sonic games do for things like loops too - temporarily take control away from the player when they're currently doing something they don't have any/much control over). Then you can see Sonic do all his crazy motion through the world without any camera troubles.

I Wish I Could Download Some Of Your Games. I Love Them!!

Good job bro!

Me:sees the loop physics Also me: OH GOD ITS '06 AGAIN

sad that you didn't remake Sonic 06, but great game and video nonetheless lol

how to get rid of the huge lag spikes with the rings: step one: when the rings spawn, turn of collisions. step two: when the rings aren't touching anything, turn collisions back on. simple.

I haven't seen anyone bring this up in the comment section but when you 100% Sonic Adventure 2, the reward the game gives you is a playable Green Hill Zone. Much like yours they actually went out of their way to translate the level design of the first Sonic game into 3D. I recommend checking it out

For the ring-collision issue, you could write a script that when Sonic gets hit the rings don't have collision for a few seconds, and then turn the collision object back on.

Sonic: [stands still on the ceiling of the loop] Me: [“Sonic goes for a walk” flashbacks]

“Hi. I would like to have. Some lemonade.” I laughed way harder than I should’ve.

Even though it’s 2 years later, just wanted to let you know that you can absolutely release this.

Hey, CLWEnt here! The guy who uploaded that model to sketchfab! The story behind that model and the fact it had all the animations is a neat one, so lemme spin ya a little yarn. So, from 2019 to 2020, I worked on the Sonic Runners Revival project (which is still going on to this day, proud of them) as a graphic designer for new events and event images. So to get a start, I tried working with models from the game, as well as models from other Sonic games (theres a ton of models on there that are still drafts, and as such, not public.) that I could modify and use in my event images. This includes the Classic Sonic model you used in the video, which I modified and used for the Sonic 3 event image. But how did I get the model complete with the animations? I'll tell you. So in the earlier days of the project, a member of the team (who's name I cannot remember, this was two years ago and I believe they left early on, I could be wrong) decompiled and dumped all the assets of the game for the team to check out and use if they wished to. And being the lead graphical designer at the time, I had a field day and a half XD. But the decomp was *huge* and a pain to navigate through, so I just took the things I needed and put them in easier places to access, like Google Drive or in this model's case, Sketchfab. I don't work on SRR anymore, I retired late last year, they've gotten a bunch of new people in my place since then that do an amazing job, and I'm super proud of them. Anyways, that's the rambling, and amazing job on *your* project here, Cody!

Funny story: Sonic Adventure 2 basically did almost exactly what you did, except the layout isn't linear as the original or your version, but it's still basically act 1 from the original

Kinda wild how similar yet different this is to GHZ in Sonic Adventure 2. Like, you both made the same level, just... Different.Also, official Sonic games fix that issue with Ring Loss but just making it so when you lose rings, only up to either 20 or 32 spawn, depending on the game.

I'm sitting here wondering if he ever played Green Hill in Sonic Adventure 2. That level is exactly what he wants to make.

And this is why the Homing Attack is so useful for 3D Sonic

1: sonic Adventure 2 already did this when you got all emblems, and 2 there is also a sonic 06 restoration going on right now, all of sonics levels are available (trial select not story)

excellent video! God bless you and yours!

This is awesome!!! You should do chemical plant next

The ring collision thing, disable their collision with the same object type and apply an impact/physics force to push them all apart.

Sega doesn’t mind if you remake their games or make fan games about sonic “CodyCantEatThis” so just upload the game! (Edit: Wow! 240 Likes, That’s A lot Of Likes!)

I'd love to see this updated with momentum, rolling, and maybe even the spindash (since it and the drop dash have been backported to most games that didn't originally have it)

So awesome!!

Sonic Adventure 2 intensifies Also, for the ring problem, make a max number of games rings that can spawn like 20 or 50, and make it so they can’t interact with each other.

"Sega forgot to add a third dimension to greenhill zone in Generations" 2nd act though?????????

8:22 so were gonna ignore how the buzz bomber almost killed the other buzz bomber 😭

For The Ring spawn lag you could use Coroutines to spread out The spawning over a few frames with yield return null and a loop of like 20. Also you could spawn them around Sonic a bit with OnUnitSphere and perhaps give them momentum at spawn and wait a second before activating their collisions?

4:41 oh hey thats my old sonic head render in a good use XD nice job on the game!

2:58 “ huge thanks to this guy” *then proceeds to roast his animation*

nice game! but you forgot to add the flickies (the little animals in sonic) that when you kill an enemy, they appear out of them!

I think a 3D Blast 3D remake would be fun! Imagine playing through the levels with actual camera controls, and being able to see the distance you're jumping.

20 years to late, they already did this in Sonic Adventure 2

4:04 for tunnels working with the camera may work. Still teleport the character, but trace the camera over the imaginary path inside the mountain + add sounds of sonic squeezing. Should have a cool effect

I really do know almost nothing about game development, but following basic logic, i think you could turn off collisions between the rings for the first split second, and then have them turn back on.

For the ring thing, don’t make ALL the rings get out, and just make 20 or something get out, just like SA2

To fix the ring issue, go into the project's Physics settings and disable layer collisions between Ring and Ring. That way, rings won't collide with other rings.

A tip for the rings : Instead of dropping all the rings u have when u take damage, make it only drop to 20 when the rings u collected are more that 20 since that's how it works in the original game

8:33 well that's because that's not Sonic, he doesn't run fast the second he walks, he needs acceleration, he needs momentum. Sonic isn't about being fast, is about learning how to be fast. (But i can understand that would be difficult to program)

Hi! Sonic nerd here! In every game, sonic doesn’t drop 100+ rings at once, he’ll drop a max of 20-30, BUT in knuckles chaotix there’s such a thing as the combine ring! The rings will grow in size, they’ll be less, but each one is worth a multiple, like 5 for each one, hope this helps!

And then you realize Sonic Adventure 2 did the same thing as a secret level

For the rings dropping after an attack: In other 3D Games, only up to like 20 or so are dropped at max when hit. They are spawned around a circle with sonic being the center and Unity has its own spawning tutorials for spawning objects in a circle at runtime. Also to prevent them from being instantly picked up again, you could deactivate the colliders for like 0.25 seconds or so. As to not make them collide with each other: check out the editors Physics Tab! You can set up which layers can collide with each other and which would ignore collisions - put the rings on their own layer and then disable collisions of this layer with itself, that should work like a dream.

Good job !

This is very cool

An idea to solve the rign spawn lag (if it is caused by the physics calculations). Make an specific layer for the rings and set that layer on the ring prefab. Then in project settings modify the collision properties to avoid objects of the "ring layer" to hit other objects of the same layer. With this, the rings will collide with al objects except other rings. I hope this helps ;)

Sonic: clears stage Also sonic: guess I'll die

0:33 I did NOT need that hit of nostalgia

for the rings, there was a solution even the original devs used that i noticed where no matter if you've collected like 100 rings the game will make you drop only 30, probably for performance too

Yeeeeah, this is why Sonic Generations didn't remake GreenHill in "3D"

When sonic is upside down on the loop Me: sonic 06 is that you

6:51 on that part, make it so that the rings are non-collidable, it could work, but I don’t know any other solutions.

how to fix the lag spike: so bassically go into blender and try to low down the verts. And select all the verts and make them collision off in blender. Then put them into the game and select them in the pool or what you call it. And make them non collision

Consider lowering the acceleration, in the original games he takes time to gain speed and slow down.

0:44 bro, its in almost every game that was loved by the fanbase. SA2, SG (as you just said), Sonic Mania, etc.

u forget to mention some things like the start menu and when sonic loses all his lives? Also Keep The Good Work

The moment codycanteatthis will reach 600k yayyyyyyy

6:50 for one thing, when sonic gets hit, the counter drops to zero but he only drops 20 rings, regardless of how many the player had.

3:39 you've already taken the first step to remaking sonic 06

You are allowed to release this game if you want. SEGA doesn't care about fan games, especially fan demos like this. Same for Valve games, their company is actually putting their games on open source engines, because they actually want you to mod it and make fan games of it as well as play it.

For the ring solution, make it so the rings will group up into a bigger ring, making 10 rings effectivley one larger ring.

0:30 omg, I forgot about that cartoon

6:55 You can probably make a trigger under the ring so when it hits on the ground it will active collisions, so it doesen't lag

3:59 A solution would be a camera prespective change into a sidescroller view like in mario oddysey's 2d sequences

Bro recreated the faunal level in sa2! I’m not hating I love this man’s vids and I’m starting unity because of him

3:41 Yey sonic 06 physics :D PHYSICA FROM MY FAVORITE SONIG GAME!

2:12 ah yes, my Favorite company, *F O N Y*

I think it would be cool to see a remake of this with new models that match the voxel esthetic of your newer 3d remakes

Im an unreal dev, never really used unity, but in unreal we have collision tags we can use to have the engine ignore collision calculation against entities what a matching tag. If unity has something like that it might be worth looking into. Besides that, honestly the actual sonic devs solve this issue on the genesis by spawning only a max of 20 rings. You could get around this by creating 10-stack rings, basically special rings worth 10 rings, and then just calculate the number of times your ring total is divided by 10, spitting those out as 10 stacks, and then spit out the remainder. This is over a year old and Im sure youve figured out a number of things by now

You missed programming the "Momentum", the Momentum is like gravity, for example. You want to go through a looping and you run towards it, but from a very short distance, and you cannot make the complete turn, because you have to have more speed going down a hill rolling or something similar, that is the "momentum"

You could have made the fish jump over the bridges otherwise they're just cosmetic

i know the best solution for the ring issue, when you have like 100 rings in sonic 1, and you get hit by an enemy, the exact count of the rings you collected wont drop, it will only drop like 10-15 so the game wont lag (this was in all sonic games i think, sonic mania only drops huge rings and some small ones so you can go with that too)

regarding the ring concern: if i remember right the orginal aproach was to spawn a small amount of rings around Sonic, meaning in radius without colission, he could grab back and decrease the counter to zero.

Ring Collision: Bring in 5 - 10 per iteration at random locations around a sphere of sonics transform.position from the object pool. Offset the next iteration by the diameter + radius / 2, etc. This will avoid object collisions.

How a sonic fan, i can say, this is so beatiful and incredible but You forget the spindash 3:39 “sonic 2006 moment”

Something to about the tunnels you could make it similar to the tunnel sections in Metroid Prime. There the tunnel is typically on the side of a wall rather than further inside it. That allows the you to make it visible to the camera by making the tunnel transparent on that side of the wall.

To CodyCantEatThis, I like what I see but there are things I want to suggest to you to help and improve this project. This are just my thoughts and ideas, hopefully they help you. So, here I go! 2:20 Spread the item computer screen apart so they aren't cluttering the same spot. 2:34 Maybe have only a few springs in the bundle of spikes so that way the player has to go from one spring to another as an obstacle. 3:32 It looks rigid, the loop inside looks like it doesn't have much space to do a proper loop around and probably needs to be bigger for sonic to do it. The moment sonic got half way, there wasn't enough space and looks like there are collision there. Other then that, you can either have Sonic have a script loop around or have that moment in first person until exiting from the loop. 3:44 You can make the tunnels visible to the players when Sonic enters in it and it becomes un-visible when exiting out. Also, here's an idea for ya, when there's more then one tunnel or paths, you can make them go different directions to make the stage more real and not just straight ahead. 4:17 Make them break when hitting the ground or make them hit the ground before rising back up after a few seconds. 4:37 Why not make a orangish gold rings that glows to represent as the 5 rings, and add a number 5 in that ring to let the player know that that's how many it contains. That way you can use less rings on stage and when Sonic loses rings and you can have more Memory Space. If not that then have the rings be transparent for a temporary time and if it detects a ring occupying the same space then it'll move away until it isn't or it vanishes. Also the rings bounce up and down when Sonic drop them, probably to make it easier for them to scatter. Or fuse any rings Sonic drop that made contact to another ring Sonic drop into a ring with a number indicating how many ring value it currently has. Or make the rings Sonic drops not have collision when spewing/dropping out of Sonic. 5:35 You can make the Chomper's jump over the bridge to try and bite out of whatever goes on the bridge. 5:39 You can make Motorbug have a revving before charging at Sonic to ram him when they spot Sonic in a straight line view. 5:41 Crabmet(don't know how to spell its proper spelling.), make it snap it's pincers from either of it's side whenever Sonic is within range or when they reach the end of their paths(just so the players know that they can attack you now and not just because of hitbox contact.). 7:22 Make that invincibility for 9 to 12 seconds to make the players hurry up because of their screw ups or have it shorten time span every time you it happens until you leave the stage or clear it. Lastly, five things: 1. Make the stage longer and not just make it wider, just widening it makes the stage feel short. 2. Where's Sonic Ground Spin Dash? 3. Sonic has a short slow walk before gaining speed when walking/running. 4. Camera Screen is too far out, zoom in a bit. 5. Where is Sonic's Blur effect when he's spins when jumping?
