hard trigger question

does any1 know a non jass way to make a thrid person view that follows a unit, pzzzz tell me how

Lol i just anwsered this for another person.

Start:
I like the one when it is right behind the unit, so the

(Apply a camera like this at the start of the map.)
angle of attack: 0
Z offet: 150+
distance: 400-1000
lock camera to unit

Then making the camera turn the way the unit is facing.
Event:
Every 0.25 seconds of the game

Actions:
Lock Camera to unit
Set Camera AOA to 0.
Set Camera Distance to 400-1000
Set camera rotation to "direction unit is facing" over 1 second.

Please Note:
-I dont know if you can change the hieght of the camera, personal I have tried many things and could not do it, other than when unit enters region ect. So if a unit went up a map the camera would stay at the same height.
-I do not have the WE open so the actions are not exactly the same.
-The reason I use lock camera to unit is because it saves some use of triggers making it produce less lag.

thx
