Mouse event:

OnMouseEnter (): enter with the mouse

OnMouseExit (): move the mouse out

OnMouseDown (): Click

OnMouseUp (): move the mouse up

Static GameObject Instantiate () Clone

Static void Destroy ()

 

Position, material, collision, rendering

Terrain, pre-made, camera, collision

 

Using UnityEngine; using System. collections; public class shubiao: MonoBehaviour {// Use this for initialization void Start () {}// Update is called once per frame void Update (){}//: enter void OnMouseEnter () {gameObject. renderer. material. color = Color. black;} void OnMouseExit () {gameObject. renderer. material. color = Color. blue ;}//: move the mouse out of void OnMouseDown () {gameObject. renderer. material. color = Color. yellow;} //: Click void OnMouseUp () {gameObject. renderer. material. color = Color. red; GameObject. destroy (gameObject);} //: move the mouse up}

GUI Layout

Using UnityEngine; using System. collections; public class GIU: MonoBehaviour {private string str = "zhangsan"; private string str2 = ""; private bool sex = false; private string _ userName; // Use this for initialization void Start () {}// Update is called once per frame void Update () {} void OnGUI () {/* if (GUI. button (new Rect (10, 10, 70, 20), "Button") {print ("A");} if (GUI. repeatButton (new Rect (10, 100, 70, 20), "button") {print ("B") ;}str = GUI. textArea (new Rect (10, 20,100, 20), str); str2 = GUI. passwordField (new Rect (10,150,200, 20), str2, '*'); sex = GUI. toggle (new Rect (10,100, 50, 50), sex, "male"); // check */GuI. label (new Rect (10, 10,), "User Name"); _ userName = GUI. textArea (new Rect (100, 10,200, 20), _ userName); _ sex = GUI. toggle (new Rect (10, 70, 50, 20), _ sex, "male"); _ sex = GUI. toggle (new R Ect (10,140, 50, 20 ),! _ Sex, "female ");}}

GUILayOut Layout

Example 1: private string str3 = "tested string"; // global variable
GUILayout. button ("GUILayout Button"); if (GUILayout. button (str3) {str3 + = str3;} if (GUI. button (new Rect (50,100,100,100), str) {str3 + = str3 ;}

 

Example 2: GUILayout. beginHorizontal (); // horizontally arrange GUILayout. button ("I am GUILayoutButton"); GUILayout. button ("I am GUILayoutButton"); GUILayout. button ("I am GUILayoutButton"); GUILayout. button ("I am GUILayoutButton"); GUILayout. endHorizontal (); GUILayout. beginVertical (); // vertically arranged GUILayout. button ("I am GUILayoutButton"); GUILayout. button ("I am GUILayoutButton"); GUILayout. button ("I am GUILayoutButton"); GUILayout. button ("I am GUILayoutButton"); GUILayout. endVertical ();

Move w key A key S key D key:

Using UnityEngine; using System. collections; public class fouth: MonoBehaviour {// The right side is the Z axis, the top is the Y axis, and the X axis is invisible; GameObject go; // Use this for initialization void Start () {go = GameObject. find ("Cube3"); go. renderer. material. color = Color. red;} // Update is called once per frame void Update () {if (Input. getKey (KeyCode. w) {go. transform. translate (-5 * Time. deltaTime, 0, 0, Space. self);} if (Input. getKey (KeyCode. s) {go. transform. translate (5 * Time. deltaTime, 0, 0, Space. self);} if (Input. getKey (KeyCode. a) {go. transform. translate (0, 0,-5 * Time. deltaTime, Space. self);} if (Input. getKey (KeyCode. d) {go. transform. translate (0, 0, 5 * Time. deltaTime, Space. self );}}}

Rotation:

Using UnityEngine; using System. collections; public class NewBehaviourScript: MonoBehaviour {// Use this for initialization void Start () {}// Update is called once per frame void Update () {// rotate gameObject. transform. rotate (0, 15 * Time. deltaTime, 0, Space. self );}}

Collision:

void OnCollisionEnter(Collision co)    {        co.gameObject.renderer.material.color = Color.blue;    }

Pre-fabricated (clone ):

void Update () {        if (Input.GetKeyUp (KeyCode.Space)) {            GameObject.Instantiate(go,gameObject.transform.position,gameObject.transform.rotation);                }    }

Void Update () {if (Input. getKey (KeyCode. leftShift) {if (Input. getKey (KeyCode. leftShift) {gameObject. animation. play ("run"); gameObject. transform. transform (Vector3.forward * Time. deltaTime * 6); // forward and backward movement Distance Speed} else {gameObject. animation. play ("walk"); gameObject. transform. transform (Vector3.forward * Time. deltaTime * 0); // forward and backward movement Distance Speed} else {gameObject. animation. play ("stand"); gameObject. transform. transform (Vector3.forward * Time. deltaTime * 3); // forward and backward movement speed }}

 

Shadow baking: sets a shadow for the lamp, sets the rest for the baking, and enables the windows light baking back;

Animation Editing: None

C # animation control:

 

Application

Switch scenario

  if (Input.GetKeyDown (KeyCode.A)) {            Application.LoadLevel(0);                }

Screenshots

if (Input.GetKeyDown (KeyCode.Space)) {            Application.CaptureScreenshot(@"c:\1.png")                }

Open a website

Application. OpenURL ("H"); // open a URL

Exit:

Application. Quit (); // exit

Left-click the game object to disappear

If (Input. getMouseButtonDown (0) // If you press left to hit {Ray ray = camera. main. screenPointToRay (Input. mousePosition); // get the clicked position RaycastHit hitInfo; if (Physics. raycast (ray, out hitInfo) // click {Destroy (hitInfo. collider. gameObject); // destroy the game object }}
