About Trailmakers:
In the toughest motoring expedition in the universe, you and your friends will build your own vehicles to cross a dangerous wasteland. Explore, crash horribly, use your wits to build a better rig, and get as far as you can with whatever spare parts you find on your way.
Welcome to the Ultimate Expedition!
Journey over grueling mountains, hazardous swamps, and bone-dry deserts on a distant world far from civilization - it is just you, your fellow adventurers and the amazing, jet-powered hover-buggy you built yourself. Explore, crash your vehicle, build a better one, and get as far as you can with whatever spare parts you find along your way.
Trailmakers is about building very awesome vehicles and machines, but you don’t need an engineering degree to get started. The intuitive builder will get you going in no time. Everything you build is made from physical building blocks. Each block has unique features like shape, weight and functionality. They can be broken off, refitted and used to build something new. Individually the blocks are fairly simple, but combined the possibilities are endless.
Expedition Mode is the challenging campaign mode of Trailmakers. You are competing in an off-world rally expedition with only a few building blocks to get you started. You must build, tinker with and rebuild your machine to progress. Journey through a big world, overcome deep gorges, angry wildlife and dangerous weather to progress and find new parts that will juice up your machine. The world in Expedition Mode will test your survival skills and ingenuity.
Sandbox Mode is where you want to head for an unrestricted, sandbox, vehicle-building experience. Here you can build anything you can dream of, and play around with it in the world of Trailmakers. It is a great place to test out crazy machines, and experiment with the physics engine. With tons of different blocks, hinges, thrusters and interactive vehicle parts - the skybox is the limit.
Trailmakers is even more fun if you play it with other people. Build cool vehicles and compete in mini-game modes with your friends or other Trailmakers online. Build a helicopter, send it to your friend, and shoot them out of the sky. Put two seats on a tank, and let your friend control the turret. As we get further in Early Access development Expedition Mode will also be adapted to multiplayer.

[@Hadeks_Marow]

No he wasn't. That speed was the calculation of the teleportation, not his actual travel. Speed in this game is calculated by distance over time. 1 frame he was in one position, the next frame he is teleported somewhere else BY respawning. Time is those 2 frames, distance is how far he teleported. It's an oversight on how trailmakers handles teleportation which carries over with alot of their different systems. Point is, that 2000 was not actually from buoyancy, but rather just the natural (unintended by the devs) occurrence from respawning while in a moving vehicle.

[@CaptainFlips]

You might break the sound barrier with this if you place the seat at the top. The game has to have some point of reference for the sound barrier and if it's the seat (which seem likely), by placing it at the top, you're basically bringing it out of the water at max speed, not at the speed that the vehicle has once it's completely out.

[@Blackbirdtree1]

Me: Racking my brain, trying to understand how something can be more buoyant in air, but far less buoyant in water... The game, which relies on code, and not actual physics: Bruh.

[@ledocteur7701]

It actually has the same buoyancy in water and in air, it's hydrodynamics that make it much slower.

[@tombroad9239]

@@ledocteur7701 Does that mean... the pontoons are more buoyant in water...? Buoyancy should contribute a force consistently relative to the density of the surroundings. Assuming the balloon is exerting the same relative force, that being enough to ascend at ~20 in water, and then at 160+ in air... How does the pontoon rise 3x faster in water, but not at all through the air?

[@TeeJai2010.]

The pontoons, as you explained, are reactive to the environment; if you put air or carbon in water, it will most likely float, but if you put air in air, it most likely will float down; this is because things float due to its forces being less dense / lighter than its environment ex: water, air.

[@tombroad9239]

@@TeeJai2010. If I understood that correctly... Such a functionality exists only for the pontoons? If it is the pontoons which change depending on the environment, their weight-offsetting force must decrease drastically in the presence of air. For the balloon to rise at 20 underwater, and at 160 in the air, the drag must be 8 times greater in water. The pontoon, with comparable volume and comparable drag, rose at 60, that being 3 times the rate, meaning it was 1/3 the density. If that's seriously how the pontoons work, and then they're programmed to lose their excessive buoyancy once they reach/pass the water's surface... that's kinda dumb. At this point, it's worth mentioning; Each part has a weight stat, but Scrap didn't seem to be paying too much attention to these. I'm not sure that they relate directly to the buoyancy of the part, but I wonder what their relation is...?

[@ledocteur7701]

@@tombroad9239 In this game it's not relative to pressure, because pressure doesn't exist in the game. "Buyancy" is also not real, instead they just give upward thrust that mimics buyancy, it's essentially a thruster wearing a disguise, and they activate based on the environment it's in. what does exist is 3 environments, "air", "water" and "space", the pontoons only give "buyancy" when in "water" and the balloons give "buyancy" when in "air" and "water", but that "buyancy" is the same amount of thrust. And yes, pontoons do have more "buyancy" than balloons, but they are off when in "air".

[@georgethecat5150]

Don’t you love when logarithms are everywhere, especially diminishing returns like adding more and more pontunes on the effect of weight

[@jaspermooren5883]

It's more the hydrodynamics though than mass. Both air and water resistance is relational to the square of the velocity. So going faster quadratically makes the resistance go up. Technically there's some more stuff to water than air (well super technically not, but the viscosity of air is practically 0), but the basic stuff is the same. And I highly doubt Trailmakers calculates it any different, since their aerodynamics and hydrodynamics math seems to be fairly simple. If it was relating to mass, the effect would actually be bigger, since the effect of the weight of the diving bell will get closer to 0 by adding more pontoons.

None of these numbers were genuine. That was an oversight in how teleporting works in the game. That "speed" was calculated based on the previous position (before he teleported) and his current position (after he teleported). It's an unintended oversight in how the game is programmed.

Dude _repeatedly_ saying "area" when he means "volume" would have been fighting words in my 9th grade geometry class.

[@SnakeMichael]

He also keeps saying “aerodynamics” instead of “hydrodynamics” which is bugging me

[@buckduane1991]

Sound travels roughly five times faster in sea water than it does through air, and even then it varies depending how deep you are due to pressure. The “valley” of the wave as you called it is actually called the “trough”, and the crest is called… the “crest”. You want a ship to face into them so waves break across the bow, whereas if your ship is running length down the trough, the next wave can and will roll you over and capsize you. The RMS Queen Mary nearly rolled over when struck by a rogue wave while carrying thousands of US Troops in 1943, rolling to 45 degrees and holding their for what felt like an eternity before she finally righted. Lusitania also experienced a rogue wave that tore her upper bridge off.

[@Nojaru]

When expanding horizontally, realize that a vehicle with two columns of pontoons is functionally the same as two separate single column vehicles except that with the two-column vehicle, each column is accelerating half a diving bell, while the single column vehicle is accelerating the whole diving bell.

[@Lectrikfro]

It's a shame that adding a bunch of logic to do some sort of staging so it can shed weight as it approaches the surface (eliminating the weight of the pontoons after they break the surface when they no longer provide buoyancy) would probably just lose just as much speed to the extra weight as it would gain

[@IgnavumFortuna]

Technically, there is such a thing as surface drag. And if you double the width (in two dimensions) you get more lift per surface area. I'm just not sure if Trailmakers considers that kind of drag.

[@sterlos1499]

@@Lectrikfro would cause a zero drag glitch and be cheating anyway

[@lucidocelot]

I love that you keep coming up with new ideas for this series

[@lohan1361]

It's better to put them in a big flat square than a tower if you want to maximise the jump, because once the pontoon is out of the water it becomes dead weight, and when about half of them are out of the water you already start loosing speed ( technicaly with a 100 tall tower it wouldnt get out of the water)

[@francislacap4800]

Water has physics in trailmakers

[@ThePhonax]

Yea but a big square literally gets no speed to get out of the water

[@ledocteur7701]

hydrodynamics however absolutely destroys the benefit of a big square.

[@Hadeks_Marow]

@@ledocteur7701 Yeah agreed, but a flat line works better than a tall pole though. Yes, it requires more hydrodynamic blocks to make it less resistant, but the tradeoff is worth it. You don't want the bottom fighting with the top, because at that point, that is forces fighting with eachother. No bueno.

[@ledocteur7701]

@@Hadeks_Marow I mean.. in real life a flat line would be better, but with the game simplified hydrodynamics, it's the same thing as a big square, since water doesn't "flow", all that matters is how many drag arrows you have, aka the surface area, which is the same for a square and a line with the same amount of pontoons.

[@Hadeks_Marow]

Hey scrapman, Remember when I explained how trailmakers deals with positional data when teleporting? It was in your space video testing max speed. You found the trail particle system was acting weird due to teleporting across the map. Yeah, same thing here with your 2000 speed. Speed is distance traveled over time. By respawning, your position 1 frame was where you where, your position next frame is where you respawned at. That "speed" isn't you actually "traveling", it's the calculated speed of the teleportation. You did NOT go super sonic, I'm sorry to say. This again is an oversight on the devs not clearing the values on teleporting. I will however suggest that you try going long instead of tall. Tall means that not only will you have less up travel, but the bottom buoyancy will be fighting with the top. Buoyancy naturally wants to be leveled. By making it tall instead of going sideways, you are actively fighting against the forces. On top of that, once the peak breaches, the parts above water are effected by gravity giving you downward force when what you are aiming for is upward force. Yes, this will mean needing more blocks to help with aerodynamics, but the tradeoff is worth it. Trust me. Wide > Tall.

[@guardiantko3220]

getting mad ancient aliens vibes near the end when editing did the slow mo zoom in and the music lmao love it

[@Ceractucus]

ScrapMan, I have two ideas for how to reach Mach 1. The problem is that as soon as the pontoons reach the surface you are sacrificing speed to lift them above the waterline. Solution 1: The long shot. For every cluster of pontoons (every 4 for instance) separate them with a destructible connector that is set to disconnect when altitude reaches air. This way, most of your weight is generating buoyancy (speed). Solution 2: The pontoons on the bottom generate the most buoyancy, so expand the bottom by adding more pontoons to it.

[@yohoki4642]

One thing that might have helped just a bit, you could probably have used the smaller pontoons (4x2x2) as structure blocks in the cones. It probably wouldn't have helped a lot, but they're adding negative weight underwater, so it would be something. Maybe enough to hit the 1200 consistently since you were so close.

[@rjgraylight]

I'm fairly certain that the height of the creation is hindering it's max speed. As you mentioned, the amount of time in the water has an impact on how much speed it can build it. Your creations weren't getting nearly enough time underwater, so the logical thing would be to make it shorter. Bigger isn't always better.

[@steeljawX]

Scrapman's just making reverse dive toys for mermaids. They're float toys. "It's going closer to the surface You're going to have to hold your breath the further out of the water it goes!!!! 1.3 meters high on a single breath!!!! WHOA!!!" Meanwhile some 'posh' urbanite mermaid moms hanging out by the reefs, "HEY KIDS!! We already told you, stay in the deep end of the floating pool! Only big mermaids can float in the shallow end!" Sorry, it's Monday and I need something to keep my mind entertained while I drone on at work. Also, I feel like in some edited universe, Scrapman ends up buoyancy launching himself into the Spacebound DLC map and then it's just a Shooting Stars meme all over again.

[@zombiemage1451]

since those last few versions were all so close together, i wonder if it might actually improve your results if you took the wide version and removed a couple vertical layers of pontoons so you don't have weight leaving the water as soon and effectively give yourself more 'runway'

[@traubeminzeberlin]

Sound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air.

scrap man you forgot about square cubes law, you get less surface area and more volume each time the tank gets bigger

[@the_Acaman]

I would try a less tall pontoon tower after some point- the wider version I mean. That many pontoons going out of the water early may be the reason you hit a cap in speed

[@grantarmstrong2968]

Challenge: create a vehicle that is powered by buoyancy. Essentially, this would mean all your thrust must be vertical (meaning you can use the pontoons and even air balloon). Your goal is to create a vehicle that can redirect that vertical thrust into horizontal to create a vehicle that moves through the water by dolphining through it, using the force of bouyancy (and possibly adding extra force using the air balloon) to move

[@Yesenn]

Scientifically, any "boyancy only" object couldn't break the (air) sound barrier. You actually went faster then expected. A reasonable limit is around 400 km/h.

[@ontdekkingszeiler1114]

curious what happens when shortening it again to lessen the amount of pontoons outside of the water while still accelerating, also the last few videos I'm pretty sure you would've been able to use slightly less weight by turning the wedges 90 degrees and attaching them using the single side point

[@RealTwiner]

I paused it when you did your first test at 4 columns, it reads 2040, thats nutters

[@dragongamerandart]

21:14 by going frame-by-frame, I can see that you did break the sound barrier for outside the water, you just weren't fully out of the water at that moment. Your maximum speed there was 2040 kph. 21:27 max of 1726 kph 21:36 max of 2455 kph I bet if you put more buoyancy blocks inside of the wedges instead of all grid blocks, you probably would be able to get it after lost of trials. ScrapMan, you CAN break the sound barrier with Pontoons. It is possible. You are so close to getting another barrier breaker here. I wish you the best of luck.

[@falconfirecodm4159]

if you think of it, the speed of sound in water is much faster than in air because water is denser. so maybe that is why you did not get the sonic boom in water. you need to go at least 5220 kmph to break the sound barrier in water.

OOo idea. Make explosive buoys using the power coupling to attach it to the ground. And have a race around them

[@gnomed3129]

Your build is very long, and alot of the bouyancy is spread through out the whole build. Meaning that when u launch and the pontoons go out of the water, they become weight with no more power and u will lose acceleration the further up u go. So when u spawn = high acceleration, Exiting water = low acceleration. So the best thing would be too put alot of bouyancy on the tail so most of the weight exits at the same time as all the bouyancy exits. Then u would get: spawn : high acceleration and when u exit high acceleration, which would mean u would go faster with less bouyancy that u used and it would be much shorter. if u need more explaination please comment under this😀

[@WillGrout]

[@dimoichi5841]

Make the entire thing shorter, fatter, and then cap the top for hydrodynamics, it should allow greater acceleration from being under the water longer.

Breaking the sound barrier with buoyancy... What's next, sails? JK but maybe try it with weights to see if you can sink faster than the speed of sound.

[@xkansasxcowboyx3913]

Yo scrap. When you hit your cap speed you need to shrink the height. That will get you more water to go up through. So take the pontoons frome the top and spread out to a larger profile around the dive bell. Using the pontoons to fill empty spaces between the aerodynamic pieces will reduce weight cost.

My guess as to why you go slower when you're deeper in the water is because the water pressure would make the water denser, and much like the atmosphere higher you go the faster you can go because there is less drag on the vehicle to slow it down because it's running into less molecules of stuff be it air or water or any other gas or liquid that you can travel through

[@Me-mq8iq]

Suggestion: make a hydroplane hovercraft, which only contact point with the water is a pontoon keeping you afloat.

[@HabaDaba-pe1bt]

you can't get a sonic boom because your seat is at the bottom, the sonic boom always gets registered from the seat, so because most of the creation is already out of the water before your seat you get slowed down enough to not boom, and the speed of sound is higher in water

[@SonOfmowgef]

At first I thought the boom didn't happen because Trailmakers doesn't do that underwater and with the seat at the bottom of the vehicle the game thinks it's underwater. However I went and checked on one of Scrapmans other sound barrier videos and the game actually does do booms underwater, so it should have worked. Unless something changed between then and now of course.

I need this tested again, but half the height and double the width. You need to maximize time under water to gain that speed

[@packmaster6249]

You should try cutting your height in half and add those pontoons to the sides instead of a vertical line. You could have the same amount of pontoons, but more time under the water as that seems to be the issue.

By 21:14 with 0,25 Playback Speed you can see that he got over 2000 KPH. Recognising the placement of the seat, which others concluded would be the place of recignicion for the sonic boom and the different speed of sound in water you did get a sonic boom on technicality.

[@UBAT128]

he actually reached 2455 kph at 21:36 use '' keys to play the video frame by frame when paused

[@shay5025]

You should build a porpoise style buoyancy only sea leaping creation.

[@yahiagaming7053]

9:13 😂😂 why did that cut

[@Grunk-ik9os]

It was hilarious

[@tombroad9239]

I'm honestly interested now, in how Trailmakers calculates drag. The aerodynamics displayed in build mode is one thing, and that's simple enough, but in practice, it must use a completely different system. Does it calculate drag on each face, despite only displaying the drag on the front? If so, shouldn't there at least be an option to see the aerodynamics of all 6 faces in build mode? When moving in a direction that does not align perfectly perpendicularly with one face, how does it calculate the drag across multiple faces? What about rotation, instead of linear motion? Does it factor in aerodynamics on different sections of the same face, especially factoring in an angular component? And dynamic components. When there are moving parts to a creation, which turn and do different functions on their own, how does it calculate the drag on these parts in relation to the rest of the build, and relate it back to the whole creation? Would this have something to do with how dynamic parts sometimes spasm away from the build in multiplayer, as it is separately calculating their interactions, before relating them back together? So many questions... It's apparent that there's a lot more to this system than I understand. If anyone knows anything relating to any of these questions, or even has any ideas to contribute, by all means, I want to hear anything you've got. I've never taken it that seriously, but from the way veterans approach it, it seems to be a seriously advanced system...

[@tombroad9239]

Also, the difference between water and air. In the space map, they also have varying atmospheres on each 'planet', which might be an indicator. I assume this is the most simple mechanism. All drag calculations must face a multiplier depending upon their environment. But then, it applies more drag to the parts in contact with water than it does to parts in contact with air, so it must be applied separately. BUT THEN, in the space map, when it displays atmosphere, it shows a value for the whole creation.

[@JustAWildMTTC]

I mean technically you broke the water sound barrier

[@GummieI]

21:14 actually reached 2040 at the peak at that jump (have to single step frames ofc to catch it)

[@Eternal_Night69]

I think instead of wide he should've had them on the sides of the diving bell so that he's more in line and that he doesn't need it to be so towering meaning he gains more speed with more room

[@TenableMold]

Should make battle vehicles where your only form of propulsion is shooting out of the water and bouncing on the surface.

[@hudsonrhodes566]

you shuld do a battle where you yse the buoyancy control device as flotations and have them inflated the hole time so when you shot them off the boat sinks
