moving with constant speed

I have a total of 11 objects. I want my objects to move downwards. In the update i am continously incrementing the speed value. So if 1st object moves with speed = 1, the 2nd object should also move with speed = 1. But since i am continously updating my speed 2nd, 3rd, 4th… objects speed is incrementing. So once all the objects speed = 1 is over then only speed = 2 should happen. How to do this?

It sounds like you’re incrementing the speed in the script that’s attached to each object. Instead, have a separate script that’s attached to only one object (the camera, or some other object that only exists once), and increment the speed there. That way the it will only happen once.
