LookAt: The point where the camera is looking. You can create an empty object under the player. LookAt is set to this empty object. You can easily adjust the point where the camera is looking.

 

AxisControl axis control

Y Aixs controls the vertical axis of the camera, and X Aixs controls the horizontal axis.

Value: relative position on the axis, determines the specific position of the camera

Speed: The maximum speed at which the camera turns

Accel Time/Decel Time: The time required for the camera to accelerate to the maximum speed or decelerate to 0. For example, when the Accel Time is set to 10 and the Input Axis Value is 1, the camera's rotation speed gradually accelerates to the maximum speed within 10 seconds.

Input Axis Name: Determines the name of the input of InputAxisValue. The default is Mouse X and Mouse Y. The corresponding name can be adjusted in ProjectSettings->InputManager. Since this article uses code to control input, the name is set to empty.

Input Axis Value: The input on the corresponding axis, the minimum is 0 and the maximum is 1. If the input is between 0 and 1, the camera rotation speed will slow down.

Orbits camera track

When a camera is selected and Gizmos is opened, the camera's track can be seen in the Scene window, and the camera will move on the track.

 

BindingMode: Binding mode of the camera. Different binding modes will have different tracking effects. The following is the difference between Simple Follow With World Up and World Space.
