Can not playable camera

I setted up a camera to my character but when i click on play i can’t take a look from setted camera. What i have to do ?

I suggest for you to watch videos at Youtube which explains how to implement a character from scratch. This subject is largely covered there. There are even videos which explain how to setup a new character mesh in the current character templates in the engine (third person, first person, vehicle, etc). There are also courses at which covers from the basics and they are so cheap (most expensive I think is US$ 20) it would be a good investment (once you purchase they are for lifetime) and give to you a solid and yet fast into the job very quickly.
