Constraint Chassis

I’ll be releasing my own version soon featuring some nice features, including emulation of controlled body roll and so on.

Thank you Fahed, very cool!

Nice work!
Was there a reason you used a Prismatic and a hinge rather than the CylindircalConstraint? It’s a combination of the two!

BraxbroRoblox · January 9, 2019, 1:37am

For these systems you really need a Prismatic and two hinges. I got away with a single prismatic and a hinge per wheel in mine because I use rotating the attachments to steer. I hate cylindricals btw, they are so unwieldy to work with, even in Explorer.

I used prismatic constraints to move the spring constraints in one axis

This. Is. Amazing. I have little experience with vehicles on Roblox, so this will definitely be helpful. Thanks!

Hate to bump this, but when I try making the chassis smaller the whole thing flips around. Is there a size limit?

S_undown · February 12, 2019, 10:33pm

You will likely need to adapt the forces and lengths of the constraints to match the smaller size of the chassis.

Intended_Pun · February 12, 2019, 10:34pm

That makes sense. How would I go about doing that, and more importantly, doing it properly?

S_undown · February 12, 2019, 10:36pm

Most I can tell you is to experiment. Look at all of the constraints, adjust their numbers. You will more than likely find that the spring rates are proportional to how small/light the vehicle is.

Intended_Pun · February 12, 2019, 10:59pm

Yeah this is not working at all Wish there was more documentation

ItsJustFahed · February 13, 2019, 5:35am

What do you mean by whole thing fliping around?

Edit: i was able to repo it ill try and get a fix on it

Edit2: I was able to fix this by

Positioning the axels and ReSizing the "Wheel"s

This picture helps tremendously. Thanks

I hate to bother you again but I need more guidance. (Taken from my other thread)

Repro: https://www.roblox.com/library/3058063306/Work-Van

I’m trying to make a work van but every time I turn (at higher speeds), it spins out of control and glitches.

I’ve tried randomly adjusting the constraints, re-positioning things, changing the weight of parts, and more to no avail. It would be helpful if someone who understood constraints could explain what I’m doing wrong

The damping was way to high this is my fault for keeping the default damping at 1000 , ive set it to 250 and it works fine VanForPun.rbxm (26.7 KB) , OP is also updated to have the default damping at 100

Intended_Pun · April 11, 2019, 2:03pm

I really appreciate you looking at it. This is a great chassis when I have my head wrapped around it

anon66957764 · April 12, 2019, 6:33pm

My chassis can run circles around this one.

Literally…

For real though, mine’s pretty advanced, if anyone wants me to try submitting it here I could consider it.

No offense intended though This one handles good enough! I just still believe it can be improved. Particularly in the suspension and friction areas. You can fix it purely with CustomPhysicalProperties and changes to the SpringConstraints.

I’d say make a new thread with yours including details of your chassis, documentation, etc.

anon66957764 · April 12, 2019, 7:43pm

That’s what I mean by

Submitting it to #learning-resources:community-tutorials-resources …

snewo12 · April 12, 2019, 7:46pm

That was a very quick response right there.

However, cool!
