How to make a better physics based cart that tips over still (like cart ride around nothing)

Help and Feedback Building Support
1

So I am making a cart ride around nothing and cart ride into the unknown inspired game, and I need a cart. So I read through 4 topics (Creating a cart that can go uphill and is more stable - #6 by WamblyWasTaken, Fix cart ride cart shakyness? - #13 by Miserable_Haven, How is the Cart Ride Around Nothing suspension made?, and How do i make spring constraint only go up and down? - #2 by Spooce) and tried to make a cart, but it looked like this.

I need it to have more stability.
These are what are included in the cart (PrisimaticConstraint, WeldConstraint, HingeConstraint, SpringConstraint, Attachment)

I still need help making this.

ive been going at this forever, but a week ago i finally got the right adjustments:

moves similar to the cart in game after adjusting springs

If so, could you send me the rbxm? I will tweak it if it’s not my preference.

Gravity was set to 30, youll have to tweak it for higher gravity. Low gravity gives it the slow motion effect tho

Ok, I’ll give you an update if it works or not.

Well, I put it in and tweaked the tracks, then this happened.


Note: I just set the angularvelocity of the hinges to 10.

can you tell me what settings you had for springs and also gravity?

Had this issue as well, and solved it in this topic:

Use the model i sent.

heres a video of how it works when i used it. im still tweaking settings, but rn its pretty close. i reckon with higher stiffness or dampening itd look like the game

It’s probably my fault, cause I was doing an experiment with AI to see if it could make procedural generation and it did pretty good, but the track might be too smooth.

Anyway this is what I am looking for so you can have a better reference.

Its just a slighty modified version regular suspension

Actually, I have one more issue. When I modified the cart, this thing happens when it stops.


Here is the car file if you need it.

Try adjusting springs or prismatic constraints. If the prismatic constraints arent right springs bug out. Also, the gravity was set to normal since i forgot to set it to 30 if you didnt notice, so its probably more stiffer than its supposed to be

Okay, I’ll do one of your suggestions and tell you what happened.

Sooo it has been a day and I guess I decided I wanted to keep it for fun since it’s kinda funny. Thx! I’ll also credit you in-game too.

Question though. How can I change the stability of the cart/car?

19

stiffness or the guard part inside the cart. it keeps the cart from derailing
