What exactly is our collision detector?

Up until now, we didn't see much of the whole field and where the frog is moving to. But now that we've set the camera to follow the frog, I see it doesn't go through the stones and logs. I went over the code we wrote and I can't see us doing any collision detection and restrictions. I might have missed something in the previous videos, but could you explain to me how exactly do we restrict the frog from going through objects?

Unity makes it's gameobject's use components , It provides some built in components. Some of these are todo with Unity's physics engine, the important one's being a Rigidbody and a Collider. The collider is a base component, so there are many different Colliders: BoxCollider, SphereCollider, PolygonCollider. You don't see any collision code because it's packaged in the component
