Camera follow object after certain point

I’m currently using the Smooth Follow script (which I converted to C#) to have my camera follow a platform that the player controls as it moves up and down the level.

What I would like to do is have the camera start so that the platform is at the very bottom of the screen, and once it gets about 1/3 of the way up the screen, the camera will follow it up. When it comes back down to that point, I would like the camera to again stop following so that the platform can go back to the bottom of the screen. I have tried setting a flag so that the script doesn’t start working until the platform reaches the point that I want to, but then it jumps to the new position instead of just starting to smoothly follow the platform. I’d much appreciate any suggestions.

maybe you can use a trigger? on trigger enter you can script your action.

As robertbu pointed out, the simplest solution was to limit the Y position of the camera.
