No, not like have cams on Foxy to stall her, more like just having cams open to stall her. I have been using the "ultimate" 4/20 mode strategy for FNAF 1 where you set cams to 4B then do light check, cam flip, light check, and close the left door every now and then to check Foxy
I even try to make a strategy myself where I set Foxy to 20 and did light check, cam flip, turn, cam flip, light check. And Foxy was not stalled, I even slowed down on the cam flips and Foxy still moved
