ok i found it

titlecut [" ","BLACK IN",1]
_camera = "camera" camcreate [12505.94,7881.93,100]
_camera cameraeffect ["internal", "back"]

#loop
;comment "15:31:51";
_camera camSetTarget vehicle1;
_camera camSetrelPos [2,-20,2];
_camera camsettarget vehicle2;
_camera camPrepareFOV 0.900;
_camera camCommitPrepared 1

goto "loop"

working...

i need something like this

titlecut [" ","BLACK IN",1]
_camera = "camera" camcreate [12505.94,7881.93,100]
_camera cameraeffect ["internal", "back"]

#loop
;comment "15:31:51";
_camera camSetTarget rf1;
_camera camSetrelPos [0,-10,0];
_camera camsettarget rf;
_camera camPrepareFOV 1.000;
_camera camCommitPrepared 1
goto "loop" ;for 60 seconds then goto "scene1"

#scene1

;comment "15:35:26";
_camera camPrepareTarget rf;
_camera camPreparePos [11644.01,10114.49,100];
_camera camPrepareFOV 0.700;
_camera camCommitPrepared 0
~60
;comment "15:35:26";
_camera camPrepareTarget rf1;
_camera camPreparePos [11644.01,10114.49,100];
_camera camPrepareFOV 0.800;
_camera camCommitPrepared 0
~60
_camera cameraeffect ["terminate","back"]
camdestroy _camera
end1=true;
exit;

Just use a variable that boosts, and if it exceeds a certain limit then stop looping. Kind of like a for/do loop.

i found this

Create a trigger that is set to activation "none" and in the condition box write startcount, set the countdown boxes to 20 secs each and in the on activation box write endplaneview = true. 
{titlecut [" ","BLACK IN",1]
_camera = "camera" camcreate [12505.94,7881.93,100]
_camera cameraeffect ["internal", "back"]

startcount=true
#loop
;comment "15:31:51";
_camera camSetTarget rf1;
_camera camSetrelPos [0,-10,0];
_camera camsettarget rf;
_camera camPrepareFOV 1.000;
_camera camCommitPrepared 1
? (endplaneview) : goto "nextstep"
goto "loop"
#nextstep
;comment "18:38:32";
_camera camPrepareTarget [70704.44,82796.21,-34028.41];
_camera camPreparePos [11465.79,9828.33,142.57];
_camera camPrepareFOV 0.800;
_camera camCommitPrepared 10
~20
_camera cameraeffect ["terminate","back"]
camdestroy _camera
end1=true;
exit;

this working but i get error '(|#|endplaneview)' Error undefined variable in expression :endplaneview.

why ?

also i found that if i change the ? line to

? (rf distance object)< 100 : goto "nextstep"

working without errors

but why my first script working and give error?
