Simulation like in the fps without flying

I am new in the UE, so sorry for this noob question. When I start simulation, I want to be able walk on my scene like in the real game. But player is flying.
How can I solve it?

You need to add collider for items of the floor.

Please, provide your UE project’s source, as it possible…

And - Please, don’t bump your question in 4 days. If will be no answer in 4 days, you will able to bump it again…
