Question by kite37 · Apr 14, 2011 at 10:54 AM · movementcubefriction

friction problem

Hello,

I'm currently trying to build a short sample in which I have a sort of wagon with cubes put on it.

Some of them are piled up.

The wagon is made of a cube (resized) and four cylinder, put in an englobing gameObject on which I apply my movements (no wheelCollider nor individual wheel movement, I just deed it in its simplest form). It is set as kinematic.

But here is the problem : whenever I move my wagon (even slowly), the cubes never seems to grip its surface correctly and fall from it, or start rotation or even bouncing.

I've tried using some physical material, but it didn't change the result : the cubes always ends out from the wagon, no matter the speed / acceleration I applied to it or the material properties (in my test it was a linear movement, though).

How to apply a realistic and efficient comportment to my scene?

Is there a sample to answer to my problem?

Thanks,

KiTe

If you could share the project, that would help finding the right setup, a lot of parameter can affect what you are experiencing. How many cubes, the weight or each component, the actual scale of them,, do you apply gravity?, have you mess with the default settings of the physics? etc etc etc. Vast topic. $$anonymous$$aybe do a video or a web build so that we can see how it performs, that can also help.

thanks for your answer, but after working all the afternoon (and with a bit help of a senior developper of my company) we succeeded at getting something quite nice. Tutorials helped a bit too, but I feel that I still have a long way to go before mastering physics ^^

I suggest following some tutorials...

But also as Jean said, it'd help if we seen the scripts/project

Good luck.
