Need help with cameras

I'm trying to make 3 different camera angles, 1 a sky cam, that will follow the unit around, using top view. 1 Action cam, where the camera is right behind the unit and a little above so you can see some action going on. And 1 Camera that is the same as the game camera, except its rotated 90 degrees.

So thats
1 Sky cam
1 Action cam
1 90 degree rotated cam

Anyone who can help me with this will be included in credits for sure.

TIA

1. lock camera
first create a camera with correct angle, distance, aoa, etc

event
Every (seconds) of game time

action
camera-lock camera target for (player) to (unit), offset (0,0)
using (default)

disable mousewheel, rotation etc

event
Every ((0.5-1 or something)seconds) of game time

action
use set camera fields and set the same distance, angle of
attack, roll and rotation as your created camera. you need to
create one action for each.

2: not sure about this one but first start with creating a camera as
in number 1: then,

event
Every (seconds) of game time

action

camera-lock camera target for (player) to (unit), offset (0,0)
using (units rotation)

as I said not sure about this one...

3: same as number 1, just create the camera in 90 gegree
rotation first.

Hope this helps.
