How would you make a custom vehicle chassis?


:smile: yes they did

I hear the big craze around creating vehicle chassis is using constraint objects? How, I haven’t a clue. Something to do with motors and whatever. Point is, the first thing you’re going to want to have somewhere is a force to make the car move in the first place.

They didn’t, probably how I was using them.

Yeah, I have a forward force, I just can’t figure out how to make it look realistic and how to turn.


BodyVelocity objects are BodyForces, that’s what I meant to say.

Either way, the creation of custom chassis does require scripting - I’m sure that’s obvious. How are you looking to construct your chassis, to begin with? Are you looking at constraints or something else?


My chassis’ hierarchy is

 Chassis (BasePart and main part for chassis)

I would prefer to call them BodyMovers since BodyForce is actually an object on its own. Plus that’s what the parent class of all of them is named


That’s your hierarchy, but that doesn’t really answer my question. It tells me the setup of your chassis, but not how you want to accomplish the creation of a custom chassis.

@Spynaz Oops, confused the terminology.


I don’t understand what you mean, then.

What is unclear about my post? How do you want to create your chassis? With constraints, or with motors, or what? I thought I was explicit about what I was trying to ask.

I’m just using BodyMovers (BodyVelocity, BodyGyro), because I’ve never made a vehicle chassis before. I don’t know the best way to do it.

I would suggest that you take a look at some already-created chassis to get an idea of what’s involved in the creation of one first. As I mentioned earlier, constraints would be really nice for the creation of chassis and seem to be a personal favourite as of late.

This is a model I scraped off the catalogue that may help you towards creating one:

I’m personally not versed in vehicle creation so excuse me if my reply is unsatisfactory.


I guess I’ll try using constraints and seeing where that goes. Thanks.

You can play with this what I made. It uses constraints.

Is a little old but is good for learning.

The idea of my chassis’ is that you can extend and add limbs to them.

Oh, sorry. Try this?
Vehicle chassis.rbxm


Thanks a lot. I’ll probably look through the code tomorrow and try to create my own version. Appreciate it.

I have created a physicsless vehicle build here, I can post an .rbx file if you need it.


I checked it out and it’s pretty cool, however WingItMan’s chassis showed me what I need to know, since I was looking for how to make a constraint based chassis, so it’s up to you. If you do release it, it may be better off in it’s own dedicated thread.

By the way, I like how you did the speedometer. Very nice looking.

Is there anyway I could have the rbx file?

I have made an open source place file here for anyone interested in this system to use.


This is something you should message the poster for over bumping a nearly year-old topic. They don’t have membership on the forum but they can respond to messages.

There was a debacle on this thread some time ago that the presented work did not belong to the user. Most of the content has been purged but in essence, it was an illegitimate release of Jailbreak’s chassis.

You’re better off looking into doing this yourself through use of resources and appropriate creation of threads.
