[Unity cainiao] Time

1. Time. deltatime incremental time is calculated in seconds to complete the last frame (seconds) (read-only)

You cannot control the time used by the number of frames. Each frame is different. The game generally uses 60 frames per second, that is, the updata method is called 60 times (if you calculate 60 frames and the actual situation is less than 60 frames, the object will not be moved to the desired position ), however, the actual situation is generally less than 60 frames. If you set the motion of your object as 60 frames, the action will be inconsistent. Therefore, deltatime only uses the time spent on the previous frame as the time used for this frame, because no one knows how long it will take for this frame. Now, let's get to know more about the code.
