Trouble with making a basic car

Help and Feedback Building Support

I just followed this tutorial on the Roblox Wiki: Making A Car

This is what I came out with in studio

But when I click play:

The wheels aren’t connected and (obviously) it doesn’t drive.

I’m unsure as to what I’ve done wrong as I also went through this video tutorial on the Roblox Channel

Could someone tell me what I’ve done wrong?

Car is too heavy for chassis

Hmmmmmm

Can you loosen up around the area where it connects just a tidy bit also did you group the vehicle? Just to note that tutorial is kind of old.

I suggest following the new tutorial on the developer hub: https://developer.roblox.com/videos/Making-a-Car-Joints

What do you mean loosen up the area where it connects? It’s grouped.

Have you anchored the base of the car?

#7

No because that would make it incapable of moving.

#8

Im not too about this one the chassis I use works with anchored

#9

I just tried and it doesn’t work.

#10

Alright I dont know anything else since I never actually made a basic car before.

The chassis you use probably has a script that either sets the position directly or un-anchors the base when the game runs. Anchored parts are not affected by the physics system whatsoever, and anchoring the base won’t solve the issue of the hinges not connecting.

I recently tried to make a vehicle using the old method (like @oryRBX was doing) and it wasn’t working for me either. So I just followed the new tutorials on the dev hub and it worked.

  • What behaviour do you have set in AutoJointsMode in Workspace?
    Is it Default, Explicit or LegacyImplicit?

  • Also which of the three options do you have for the join settings in Studio? (see pic)

  • And are you using a surface hinge or a HingeConstraint?

Probably easiest if you upload the place file.

Make sure everything is unanchored! Also, try welding it. I have seen many videos on YouTube teaching you how to do this, plugins like F3X have weld features, videos like this are helpful;

ROBLOX’s official tutorial

A different source I found, also working.

I have the same issue with trains, I have to write a function to MakeJoints() now. I used to be able just to insert it but now the wheels just fall off.

This works for me. Remove the script from the model and delete the brick. Place the script into the car model and it will make joints to keep the car from falling apart.

As you know, Roblox does not do automatic welding of vehicles anymore. So I recommend you use this script while having no models inside of the model you are working with:

local Car = script.Parent
Car:MakeJoints()
script:Destroy()

Sorry if I am two years late to the party. If anyone stumbles upon this, place this script into your car.
