1. Background adaptive (guitexture) orthogonal mode

voidStart () {guitexture GUI= getcomponent<guitexture>(); //the Pixelinset values for guitexture are://width:510 height:340//x: -255 y: -170Rect r =NewRect (); R.width=Screen.width; R.height=Screen.height; floatm =510/ -255f; floatn =340/ -170f; R.x= Screen.width/m; R.y= Screen.height/N; Gui.pixelinset=R; }

2. Control camera rotation resulting in 2.5D effect (perfect solution with mathematical knowledge)

floatAnglespan =0; voidUpdate () {//determine if the aircraft exceeds the visible range of the screen, and if it exceeds the position of the aircraft, 20 is set according to the Maincamera far .        if(Transform.position.x > -) { speed=Random.range (8f, 12f); Transform.position=NewVector3 (-20f, TRANSFORM.POSITION.Y, transform.position.z); } transform. Translate (0,0, Speed *time.deltatime); //2.5D effect Nextz possible value (initial value is 0): 2 4 6        if(Nextz >maincamera.transform.position.z) {//Author's method://Float mx = 3 * Mathf.sin (TRANSFORM.POSITION.Z/2) * time.deltatime; //float mz =-mathf.sin (TRANSFORM.POSITION.Z/2) * time.deltatime; //mainCamera.gameObject.transform.Translate (MX, 0, MZ);            floatAngle = Time.deltatime *5.7f; //change the background and camera rotation, resulting in 2.5D effectmainCamera.gameObject.transform.Rotate (vector3.up, Angle);            GameBackground.gameObject.transform.Rotate (vector3.back, Angle); //My method: Calculate the angle of each rotation of the cameraAnglespan = Maincamera.gameobject.transform.localeulerangles.y-Anglespan; floatDistance =vector3.distance (gameBackground.transform.position, mainCamera.transform.position); Vector3 ZZ=NewVector3 (-distance * Mathf.sin (Anglespan *Mathf.deg2rad),0, Distance* (1-Mathf.cos (Anglespan *( Mathf.deg2rad))); MainCamera.gameObject.transform.Translate (ZZ*time.deltatime); }

The picture on the left is the normal state when the shark is not hit, and the right is the state after the shark has been hit two times.

When the shark was hit, In order to achieve 2.5D effect, perfect to rotate the camera and background map, and move the camera, the camera and the background of the rotation to do, is to give them the same angle to rotate, but after the rotation, in order to maintain the camera's original shooting angle and the screen, how we move it, this requires a certain angle of rotation for the camera's landing point, : The location of the camera (0,0,0), the position of the background map (0,0,20)

Other trivia:

1, the role of translate: is the sign to indicate the direction, the value represents the moving distance

Transform. Translate (New Vector3 ( -10,-TRANSFORM.POSITION.Y + random.range (-4,-1), 0));//move 10 units in the opposite direction of the X-axis
