I Evolved This FAILED War Machine Into A SUCCESS

[@ADonutMan]

The problem is (as always) with sm's optimisation and how it handles rigid body updates, when you turn game tries to make track more "stable" so it reduces physical updates for it, this is mostly done due to the fact that when big body with a big area touches the ground the physics engine counts not one big collision but rather a lot of small 1 point collisions, which lags out the game. Until devs took (which as they said in QnA they are doing for chapter 2) a deep dive into physics engine they just made game "to not really think about it" when such collision is detected, when you put weight on the track it just updated it and the game's like oh? we're moving? so until more work is done on the physics this problem is to stay. I hope I explained it well)

[@WeaselDev]

Is there a release date for chapter 2? Because like SM with better physics would be the greatest thing ever

[@ADonutMan]

@@WeaselDev No, but it's a huge pain to do that since basically all of sm is tied to physics

What about the famous Davinci tank?

[@Drago_Whooves]

the derailment issues might be fixable by making the grove deeper

[@JamUsagi]

Probably not, because there’d still be gaps in the barrier so the tracks can go to 45 degrees. Since it tends to derail between tracks, there’s little benefit and it’d just add extra weight.

[@lestatkorsaverman]

@@JamUsagi true

[@deftknight7418]

I actually built one of these, and I've completely solved this, and it isn't by using a deeper grove. Running down the center of the tread is a rail like lip, and the vehicle clamps to the rail using two separate clamps. If the track leaves the reasonable tolerance for the center rail, you unhook the front from the seem, hop the gap, and then re-rail the front. After that, detach the rear and your good. Is this completely rediculus for a design like Scrapman's? Yes, but in my design, the tread is super heavy, so this helps to keep the carrage from tipping over, and also helps my gears mesh with my toothed track design.

You are brilliant ScrapMan. According to steamcharts, barely 2k average monthly people play this game, but hundreds of thousands of us will happily watch you play! Fix idea: 2 more wheels on top of the track to pin it (the tracks) between the top wheels and their new parallel counterparts could solve derailment as well as instability issues. Probably will need more weight on the bottom section though.

[@TrafimN]

Good job! You fixed so many issues with this machine. But, (this is my opinion) I feel like the turning mechanism isn’t the best it could be. Because it has such a small contact patch and it will have to bear basically all the weight of the whole machine, if you were on say mud, the wheel would most likely just fall through the mud due to the pressure (or large amount of force exerted on a small patch) and lose traction, rendering turning impossible. This doesn’t happen in Scrap Mechanic because the ground isn’t able to flex / bend / move. But in real life it would. Of course, you could just try and drive to harder land but, this still takes away from the machine. the whole idea of the tread was to take away pressure. Sure, it’s the weight of a tank, but because the contact patch is so massive the pressure would only be about 10 lbf/in^2 to 16 lbf/in^2. This is why tanks were made with treads, as soft terrain was a lot easier to pass, and this solved the glaring issue tanks had, if they sunk in soft terrain, they would always bottom out and not be able to get back out without the assistance of a different vehicle or a big scoop as part of the tread - aka a log that was tied to the trads in these situations - and this was due to the fact that that the bottoms of tanks where large and flat, meaning that they exerted a lot less pressure than even the tank's treads. This is why the solution with the wheel would not be the most practical. I understand that it is very hard to come up with a solution that takes everything that I've said into mind, but you guys's creativity has never failed to blow me away. The only solution I can think about is to try to make the whole big tread made up of small tracks that are perpendicular to the direction that the big track is pointed in. This way you could have tank steering when two of the sections are on the ground at the same time. Another Idea could be just to simply weld two of these things together, creating two huge tracks side by side. Thank you for coming to my TED talk.

[@SpecialFX99]

Glad you returned to this one. I felt like you left a lot of opportunities for improvement the first time. This time you addressed everything I thought of and then some. My suggestion for a vehicle would be to see if you can do a car in a ball like a hamster ball then see how much terrain it can handle. Bonus points if it can float and go across water with at least some amount of control

[@johnhutsler8122]

Dude, there's sooo many old crazy machines you could try to replicate. You should keep doing this and make it into it's own series. Combining history and building games is an excellent idea

[@vincenthavinga3963]

you can improve the steering and the derailment issue by adding a pipe to your wheels and make a sideways-one-block high rail on each track segment since the bounces only occur on the middle. this also gives th option to steer at almost any point

[@kingxavior54]

You should make a giant tank using those tracks and the cart for propulsion. Or add a gun. It looks cool already and these videos are always really cool to watch!

[@PhantomSavage]

Kind of useless as a vehicle of war, but I could see it used as an overly engineered, mars roving crop planter. Imagine that each of the track pieces were solid and spiked like a cleated shoe, and each of the spikes are narrow yet hollow like a traffic cone or needle and the core driving vehicle drops seeds through an auger on it underside as it drives. To compensate for the solid tracks however, you'd need switch the steering mechanism out with two wheels that extend out and lower from the sides of the core vehicle instead of in front of it, and the wheels would need to turn in opposite directions like an RC car can to turn in place. It'd also have to be a drone or remote controlled... because you wouldn't be able to see where the hell you're going either... but personally, I wouldn't want to be inside that thing as it operates anyway.

[@Lee-One]

[@JCLoony]

2 things that might be fun to see how they work: 1. add or remove a segment or two from the track. 2. Build a second one beside the first and link the drive unit in the center, see if you can skid steer with it.

[@virguule1]

hi scrapman, i'm french, it pronons [ bwaro machine ]. add suspensions to all weels should solve some issue maybe. Instead of making little hooks, you can make a long bar so you can hook up everywhere. Don't know if it's understandable ... Great job, keep going bro !

[@CONRAM73]

The next tank you should make is the Tsar Tank. I’m loving this crazy tank series.

[@Pystro]

Looks like some guide wheels that fold out in front of and behind the bottom and top wheels could help with the de-railing. You'd just need to put them on suspension. Because you don't just need to deal with the situation where the track forms a rectangle, but also the transitions between those states where it forms a flattened hexagon.

You could even alter your center of mass left or right using a weight on a piston on either side to help avoid tipping in some instances, so long as the weight is low on the body.

[@nassimmhamdi7464]

you can seperate the two sides of the "track" from each other and have seperate control with two buttons on the wheels from each side of the center car then it will have tank steering

[@ProPanda8D]

To increase traction maybe add the highest friction in a strip under the wheels all the way around And maybe add suspension on the bottom wheels

[@Epica_Destroyer]

It would be cool to see one with weaponry attached. How would it work out? Probably on the side. And maybe even a multiple battle or race over odd terrain.

[@obaidaaljumaili2917]

You should make three wheel controls. one for the top wheel to move by itself to help with the catching up issue. one for the bottom wheels for the same reason and the last one is for all the wheels to move at the same time.

[@nangle3.149]

I think that making the wheel base closer to the length of a track segment would make the vehicle more stable in the track, and less likely to tip backwards. Larger wheels might help with the machines interaction with the leading track joint allowing it to start pushing on and putting weight onto the next track before the axle crosses the joint.

[@rpmschannel4972]

To prevent it from bottoming out, add wheels with power to them at the place where it gets hung up. To make it able to turn, build another one and attach them in the middle. And to stop it from being de railed increase the size of the lip that’s keeping the wheels on track.

[@superbro1332]

I'd really like to see a return to the 'flip walker' using this jack-based turning. Hypothetically, you could attach a similar pivoting jack to the 'gondola' to allow it to steer as well. An alternate solution is using a set of lifting thrusters to get it into a 'hovering' state, then pivot it in midair.

[@deathsicon]

Probably reduce your detracking problem, move your turning dogs to under the on the track, and add the inside/outside wheels at the bottom, maybe add those suspension components to help stay in contact on rough terrain and add weight in for traction, or put a set of wheels in on their side trapped in a track to hold it in

First: the top wheels dont need to fit in the track. You could have arms that go out at the top then up then in then down so you have wheels on the bottom and top of the top section of track that would give better contact and might help prevent some derailment and maintain traction. Second: the outside of the track loop does not need to be flat, you could add texture to give better traction and stop slippage on hills. in scrap mechanics that will probably mean cacti.

[@bobbybobby325]

This fixed vehicle brings me so much happiness.

[@goldfishwings]

Wow! Heck of a job improving the function of this bonkers design! lol! One improvement I suggest, is instead of having the one location where you can set your hooks to lift the track for steering, use pipe pieces and run it as far along each rail as you can. This will give you a few more different options for steering locations, and as a side bonus, it should almost completely fix your derailment issues.

[@tiemanowo]

I have never played Scrap Mechanic at all, but I really like your videos.

[@martinkjrgard2180]

For better traktion put caktai on all of the track pieces. It may help.

[@HorseLooker]

I think the top could be improved massively by adding a wheel on top of the tracks that pinches down onto the current top wheel. In theory, if it was big enough to not fall in between track pieces, then it could completely solve the cycle skipping issues. And for the bottom, one idea would be to make the retaining wall 1 block higher except near the turn hooks. Or maybe making the wheels 2 wide so they have a harder time slipping out? Either way, I love watching the prices of this thing being designed and refined. Good job mate!

[@andreyemelyan5267]

You should try to increase amount of axes for the bottom part, and if you can solve the problem of bottoming out on 3 or more, you should get improvement in derailing problem, also, you can rise walls on tracks, to intercept derailing even more.

[@_Ordinace_]

I think another cool thing to make would be a horizontal helicopter, i dont think it was ever actually built and it might be really hard or maybe even impossible but i think you can do it since you managed to make the monospinner!

[@Kiwo_]

1.Idea:no more Derailing by putting the sides and lock for the turns up by one or two blocks. 2.Idea:making turning faster. 3.Idea if the incline is to high and the top wheel doesnt Touch the top, put the Piston on another button or more to finetune the lenght. 4.Idea put high friction blocks on the bottom of the tracks kinda like table legs

[@WoH9Shadow]

@Scrapman may add a upper guid rail to lower the possible positions at which the cart can derail. sure there will be a gap when the track lays flat but better then none.

[@GunsNerdsandSteel]

What if you had two of these connected by a chassis, basically making a modern tank design with a turret above

Add another bar above the wheels that is low enough to prevent derailment, but high enough to not make contact when driving. When lifting the thing, the wheels will make contact and lift the tracks. Add a piston to the center of the vehicle instead and lift the entire thing. Then rotate the piston. A bit more unstable steering probably, but not unsolvable.

[@kiwano1]

Verry fun, I suspect you would only be able to turn an IRL version when it's in the transitory state of 1 track on the ground.

[@joytrekr]

If you over and up and add a wheel to the top and and add side wheels on the bottom you can potentially fix the derailing. Also if you deactivate the bottom wheel you can move the top forward when you get stuck on steep inclines

I've been meaning to tell you this sense the video you built this and this idea suddenly came in my head to solve the turning problem.

[@boiltheoil7109]

At 18:36 you said that you did not know a solution to fix the uphill climb, I have an idea to propose. Maybe have a frame that folds up to the backside with a couple sets of tires (maybe folding inwards when not in operation for clearance) with semi-stiff suspension on the tires so that you can increase the length of the vehicle momentarily and lift the mid section (the current rear) to increase the probability of it succeeding the climb? If you do try this be sure not to make the extension too long or it may bind/prevent the track and be unfunctional.

[@RiverReeves23]

That was really fun to watch and I think it contributes to our understanding of history. I guess the logical question is could they have added a gun similar to a tank? I have a feeling that the tank was the most efficient design and despite optimisation of this design, it just wasn't going to tackle the jobs they needed without rather large design changes.

If you remove the beams in between the two sides and use better track guidance (like you did in your first video of this design), adapt the propelling of the wheels at the sides, (make it independent) you might revert this machine to proper tank steering?

A bit like your evolution challenges IRL :) It seems that the development of rudimentary track designs was made during WW1 and perfected after that, also for agricultural and ground moving vehicles.

Crazy idea, but why not suspension for the bottom wheels? And to solve the top derailing why not add a wheel that goes out to the sides, then up, in, and finally back down onto the top. Granted then you would also need to add tracks to the outside of the sections. But that would also solve the issue with sections coming up at the wrong point. Anyway, good video. looking forward to how you solve this.

What if you could tilt the treads to the side, such that the path that gets taken becomes curved? That could be a more elegant steering solution.

how about instead of suspension you can put grip (as in stripy layers of blocks )and place it at the bottom of the tracks and it will also weigh it down on to the wheel
