help for lock a camera

Can someone tell me how to create a camera wich will do the same movement as a unit (for exemple if the unit turn on the right the camera will turn too).
thx for all how answer

lock camera to a unit then use "rotate camera" action in a periodic trigger.

I'am sorry but how do you do a periodic trigger for rotate camera?

look in other map "triggor" or warchaesar

ever X seconds you rotate the camera to the units point of view.

Sorry but what is a warchaesar? (i have french version) because i didn't find periodic trigger and it is probably there.
thx for your answer

Or can you give me an example where you do it please?

"Periodic Event" is an Event choice. It's used to make something happen every x seconds, good for something being updated constantly. Here's the trigger:

E: Periodic Event - every 0.01 seconds
A: Set camera field "rotation" to "rotation of "unit""
