The above code detects that when the mouse moves to the edge of the screen, the camera will move in the specified direction
Screen.width is to get the length and width of the screen, and set the range to reach the specified position to trigger the movement effect
Among them, moveAmount controls the moving speed of the lens. At the same time, you can also set moveAmount to change according to time to achieve the effect of acceleration or deceleration.
Time. deltaTime is to control the moving speed of the lens according to the frame rate, the higher the frame rate, the faster the moving speed, and vice versa, the slower.
If you use Time. fixedDeltaTime is a fixed refresh frame rate.
