Help locking camera.

[DESTROYER123]

Hello everyone!
What I'm asking today is a bit hard....
I want a triger fuction which will lock on a unit that enters a specific region.
Check the picture I've attached to see how I want the camera to be!
However this is not the only thing.
I want the player by using the up and down buttons to move the camera up and down.
But i want boundaries. This will help you understand:
-
-
-
-
-
-
------------
I don't want the camera to be able to move outside the unit's facing point.
I hope you're willing to help me and those who help will be posted on the credits and in-game (while explaining how to use the camera)
Post only trigers please!!!!!!
Thank you.

I couldn't find a system for adjusting camera z. You need to code your own and integrate it with the system above. Do you have any jass experience?

What is jass?XD
I know what it is but I have 0 experience

Damn. This thing is very hard for me to use.......

Is there at least a way to lock camera at the back of the unit and follow his back forever even if he turn 80 degress e.t.c.?

Yes, the camera system I posted does that.

I'll try using that one (if I figure out how).
Anyway if I get this working I'll post you and the creator.(Until then +rep)
Thank you!
