[Update] Constraint Chassis


Hi , I heard a lot of people have trouble with making constraint vehicles so i made this open sourced Chassis

The Chassis Includes

  1. Suspension


  1. Mobile Support (Which means the controls are on point with the user’s input) Make sure to use the new Dynamic Thumbstick for this to work properly


  1. Configurations ( You can change them in real time)


  1. It automatically sets networkownerships


  1. Automatic Welding ( You can put a Custom Body inside the Body under the Model and they will be welded , put tires or rims under the Wheel and they will also be welded)

And the chassis is more organized.

And thats it

How do I make a car with constraints?
Help on a Chassis

Cool. Covers the basics of using contraints for vechicles. P.S maybe put all the constraints into a folder and make it slightly more organized? Such as making a folder like for the body and wheels.


Thanks - this is helpful

Stole my thunder. That’s fine, I’ll just add in some fancy scriptable features.

No, he stole my thunder, and only I can do that.

On a serious note, I’ve been trying to figure out the best way to do this for a while, and you’ve brought it to me. This will be really useful in my games.

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!

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?

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

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


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.
