Walkthrough by mouse in showroom like littleworkshop

[Parisa_Shahbazi]

Hi
I want to run a walkthrough like this project for myself by mouse. detecting surfaces like ground and stairs, and move the camera smoothly to that place like a person walking. And I want to prevent the camera from going over the wall
Can you help me with how to do it?

If first intersected object is floor then show circle and can go.
