top view? As in, you want it to be over a certain object? How's this:
position camera object position x(obnum), object position y(obnum)+camheight, object position z(obnum)
rotate camera 90,0,0

just change obnum for the object you want the camera to follow, and camheight is the height of the camera. On the ¨rotate camera¨ command, it might be 270 instead of 90, didn't test this. I haven't coded in DBP for a few months.

"

that isn`t going to work since you will rotate the camera 90deg every time you execute those lines, what you need to do is either point the camera downwards just once and then position it as many times as needed, OR position the camera like this

position camera x,y+height,z
point camera x,y,z

will make it look straight down, hope thats some help, cheers.

Use what Mentor said.

+ Code Snippet

sync on : sync rate 0
autocam off

make matrix 1, 640, 480, 10, 10
for i = 1 to 20
	make object cube i, 20
	position object i, rnd(500)+20, 10, rnd(340)+20
next i
position camera 320,401,240
point camera 320,0,240

do
	set cursor 5,5
	print camera position y()
	sync
loop

where would i set the camera for this...

+ Code Snippet

sync on
hide mouse
randomize timer()
backdrop on
autocam off

load object "cell.x",1
position object 1, rnd(500)+20, 10, rnd(340)+20
position camera 320,50,240
point camera 200,0,200
i=1

do

if ia=0
   ia=1
   iz=0
   i=i+1
   clone object i,1
   position object i,object position x(i-1),object position y(i-1),object position z(i-1)
   yrotate object i,rnd(360)
endif

if ia=1
   iz=iz+1
   move object i,0.1
   `change 10 to how big your object is /10
   if iz=10 then ia=0
endif

for a=2 to i
   if object exist(a)
      if object screen x(a)>screen width() or object screen x(a)<0 then yrotate object a,wrapvalue(180-object angle y(a))
      if object screen y(a)<0 or object screen y(a)>screen height() then yrotate object a,wrapvalue((180-(object angle y(a)-90))+90)
   endif
next a

Yrotate object 1,object angle y(1)+1

sync

loop

the height of the camera depends on the size of your level and the position depends on what object you want to be directly below the camera. You would do.

+ Code Snippet

position camera object position x(follow_object), object position y(follow_object)+height_over_object, object position z(follow_object)
point camera object position x(follow_object), object position y(follow_object) , object position z(follow_object)

[edit] If you don't want the camera to follow the player overhead and just want it centered on the level just position the camera in the center of the level and how many units it takes over the level to see it all and then point the camera at camera position x(), 0, camera position z()

Which one the center of the model? If so could you make the cell.x available or tell me its size and I'll run the code and see.

Oh I see what you are doing now. Because you are loading your object to a totally random place each time the program runs you have to use the position of object 1. Also you may want to put the randomize timer command after you place object 1 so it will always load in the same place each time the program runs but the "growth" will still seem random.

+ Code Snippet

sync on
hide mouse
randomize timer()
backdrop on
autocam off

load object "cell.x",1
position object 1, rnd(500)+20, 10, rnd(340)+20
position camera object position x(1),40,object position z(1)
point camera object position x(1),10,object position z(1)
i=1

do

if ia=0
   ia=1
   iz=0
   i=i+1
   clone object i,1
   position object i,object position x(i-1),object position y(i-1),object position z(i-1)
   yrotate object i,rnd(360)
endif

if ia=1
   iz=iz+1
   move object i,0.1
   `change 10 to how big your object is /10
   if iz=10 then ia=0
endif

for a=2 to i
   if object exist(a)
      if object screen x(a)>screen width() or object screen x(a)<0 then yrotate object a,wrapvalue(180-object angle y(a))
      if object screen y(a)<0 or object screen y(a)>screen height() then yrotate object a,wrapvalue((180-(object angle y(a)-90))+90)
   endif
next a

Yrotate object 1,object angle y(1)+1

sync

loop

No, because by calling that command, you are setting, not offsetting, the angle of the camera.

The default editor is fine.

That is why I was wanting you to change the randomize timer to after you position object 1. I would even just place object 1 at the center of a flat matrix or plain and texture it.
