How to realize camera Control by unity

This article is about how unity implements camera control. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The first and third person controllers in unity all have a script called Mouse Look, which I wrote down.

[AddComponentMenu ("Camera-Control/Mouse Look")] public enum RotationAxes {MouseXAndY=0,Mouse1,MouseY=2} public RotationAxes axes=RotationAxes.MouseXAndY;public float SensitivityX=15F;public float SensitivityY=15F;public float minimumX=-360F;public float maxmumX=360F;public float minimumY=-60F;public float maxmumY=60F;float rotationY=0F;void start () {if (Getcomponent ()) {GetComponent (). FreezeRotation=true;}} void update () {if (axes==RotationAxes.MouseXAndY) {float rotationX=transform.localEulerAngles.y+Input.GetAxis ("MouseX") * SensitivityX RotationY+=Input.GetAxis ("MouseY") * SensitivityY; rotationY=Mathf.Clamp (rotationY,minimumY,maxmumY); transform.localEulerAngles=new Vector3 (- rotationY,rotationX,0);} else if (axes==RotationAxes.MouseX) {transform.Rotate (0Magnum Input.GetAxis ("MouseX") * SensitivityX,0);} else {rotationY+=Input.GetAxis ("MouseY") * SensitivityY; rotationY=Mathf.Clamp (rotationY,minimumY,maxmumY) Transform.localEulerAngles=new Vector3 (- rotationY,transform.localEulerAngles.y,0);}}

The protagonist faces the direction of the mouse click:

Vector3 MousePositionMousePositionObtains the screen coordinates of the mouse; Vector3 p_pos=Camera.main.WorldToScreenPoint (transform.position); / / converts the protagonist's world coordinates to screen coordinates in order to obtain his z-axis coordinates; mroompos.z; / / assigns the screen z-axis coordinates of the protagonist to the mouse Vector3 wolrd; wolrd.x=Camera.main.ScreenToWorldPoint (m_pos) .x; world.z=Camera.main.ScreenToWorldPoint (m_pos) .z; world.y=transform.position.y / / y axis coordinates remain unchanged so that the protagonist will not go underground; transform.LookAt (world); / / the protagonist looks at the position of the mouse click

Slide the mouse to adjust the distance of the field of view:

Float fov=Camera.main.FieldOfView; / / get the value of the camera's adjusted field of view; fov+=Input.GetAxis ("Mouse ScrollWheel") * sensitivity; / / sliding built to adjust the field of view worth size; fov=Mathf.Clamp (fov,minFov,maxFov); / / limit the field of view value to (minFov,maxFov); Camera.main.FieldOfView=fov; / / then assign the adjusted value to the camera's field of view; thank you for reading!
