I have two questions that need help

1:How to make such an object collide?

How to change the collision condition to 1?
2:
​​​​​​​How can the role be returned to the initial position if the role meets BUG, falls map, or enters the collision body?

Thank you

I tried it,But the Pillar till could be crossed.
The pillar is the official material in the Sun Temple
