Physics Simulation Problem

I’m new in Unity3d. I saw an youtube video, a simple game. Catch falling vegetables. I tried to create something simple like in that game. But, I can’t simulate physics property like that video. Also, objects kept passed through collision wall of holder/basket.

ref. video link: here

How can I simulate that type of physics simulation, like in video? Unity’s built in physics property seems not that very useful for that kind of work.

It looks like your object (“vegitables”) has not Collider component or collider’s property IsTrigger is “on”.
