How does jailbreak do their cars?

I heard jailbreak doesn’t use physics for their cars, they use raycasting, is this true? If so, can someone explain how this is done?


This is most likely about the car suspension.
Physics method: use Roblox spring objects.
Raycasting method: shoot rays down to get the floor height and use that to determine how a custom spring should behave.

Using Roblox springs is much easier for cars. For things like trail effects, raycasts can also be used.

I recommend using springs.
If you want a flying vehicle that is limited to float a certain height above the ground like one jailbreak vehicle, use raycasts to determine the current height.
