New game, old engine...

ok, you knwo all those nasty puzzels sloving games? like brokensowrd? or bioforge? where the camera is postioned in the room, and as you walk about you watch yourself moving, and when you go into a new room or part of the same one(a new secotr) you see a vew from a different camera!
this is what i want to do in my new MP level RPG, but only when in externail view, so you can shose whether to have it or not.
So basicaly what i want is a cog that will...

Not work when you have internail view online.
will work when you have externail veiw online.
If your in a perticular secotr it shows one camera view, while allowing you to walk around.
and will work for a infanite number of secotrs(or atleast a good few) per cog.

OK... Starting up the engine! Are the COGs moving?

Good! Lets start cogging!

We shall make a cog for each room. A room can have more than one sector. First the symbols:
Code: 
symbols

message    entered

sector     rsector1
sector     rsector2
sector     rsector3
sector     rsector4
sector     rsector5
sector     rsector6
sector     rsector7
sector     rsector8

thing      rcam1
thing      rcam2
thing      rcam3
thing      rcam4
thing      rcam5
thing      rcam6
thing      rcam7
thing      rcam8

int        i    local

For every rsector you enter, the view will change to one of the rcams.
Now you want external to be external, right? Then this will be a little tricky. You will have to place you "ghost" cameras in a perticular way. You must know how steep the external camera looks. How steep does it look down on you. Then when you place your ghosts, place them at the up/down angle you want minus the external camera angle. If anybody else can explain better, please post now!
Time for the code!
Code: 
code
entered:
        for(i=1; i<9; i=i+1)
        {
          If(GetSenderRef()==rsector1)
          {
            SetCameraFocus(1,rcam1);
          }
        }
return;

I think that's all! Now, SetCameraFocus() makes the view view through a different thing but the player. If you want the view to view though the player, simply replace rcam1 with GetLocalPlayerThing(). The number before that indicates what camera should set its focus. 1 is ex, and 0 is in. If you wish to switch between the 2, simply use this syntax: SetCurrentCamera(number);

Try that one. Its based on adjoins. When the player crosses an adjoin, the view is switched to the corrosponding camera. On startup, external view will be tranferred to Cam0.

It doesnt switch the camera on startup....

A nifty effect to add would be to have the camera always looking at the player:
Code: 
symbols
thing player local
thing camera=-1

message startup
message pulse

end

code

startup:

player = GetLocalPlayerThing();
SetPulse(.01);
Return;

pulse:

SetThingLook(camera, VectorNorm(VectorSub(GetThingPos(player), GetThingPos(camera))));
Return;
end
