1.讓cube沿著矩形四個點運動
using System.Collections; using System.Collections.Generic; using UnityEngine; public class cube : MonoBehaviour { // Use this for initialization private Vector3 vec; float time = 0; void Start () { vec = transform.position;//存取坐標 } int speed = 1; floatspeed2 = 0; // bool b = true; // Update is called once per frame void Update () { //time += Time.deltaTime;//計時器 //移動 transform.localScale = new Vector3(1,1,1); transform.Translate(new Vector3(0.02f * speed, 0, speed2)); if (transform.position.x >=4) { speed = 0; speed2 = -0.02f; } if (transform.position.z<- 4) { speed = -1; speed2 = 0; } if (transform.position.x < -4) { speed = 0; speed2 = 0.02f; }if (transform.position.z >0) { transform.position = vec; speed = 1; speed2 = 0; } //transform.Rotate(0, speed, 0); } }
2.cube之按鍵操作
//transform.Rotate(Vector3.right,50,Space.World); 自轉// transform.RotateAround(Vector3.right,5);//只有世界坐標下的運動 transform.RotateAround(Vector3.zero,Vector3.up,5);//圍繞別人轉 //if (Input.GetKey("w")) //{s // transform.Translate(Vector3.forward);//局地坐標（相對坐標）(0,0,1) //} //if (Input.GetKey("s")) //{ // transform.Translate(Vector3.back);//世界坐標，絕對坐標(0,0,-1) //} //if (Input.GetKey("a")) //{ // transform.Rotate(Vector3.down);//(0,-1,0) //} //if (Input.GetKey("d")) //{ // transform.Rotate(Vector3.up);//(0,1,0) //} // transform.Translate(Vector3.right);//(1,0,0) // transform.Translate(Vector3.left);//(-1,0,0) //if (Input.GetKey(KeyCode.W)) //{ // Debug.Log("摁下了W鍵"); //} //if (Input.GetKeyDown(KeyCode.W)) //{ // Debug.Log("Down了一下"); //} //if (Input.GetKeyUp(KeyCode.W)) //{ // Debug.Log("Up了一下"); //} //if (Input.GetKey(KeyCode.Space)) //{ // Debug.Log("摁下了空格鍵"); //} //if (Input.GetKeyDown(KeyCode.Space)) //{ // Debug.Log("Down了一下"); //} //if (Input.GetKeyUp(KeyCode.Space)) //{ // Debug.Log("Up了一下"); //} //if (Input.GetMouseButton(0)) //{ // print("持續摁下了鼠標左鍵"); //} //if (Input.GetMouseButtonDown(0)) //{ // print("摁下了鼠標左鍵"); //} //if (Input.GetMouseButtonUp(0)) //{ // print("擡起了鼠標左鍵"); //} //if (Input.GetMouseButton(1)) //{ // print("摁下了鼠標右鍵"); //} //if (Input.GetMouseButton(2)) //{ // print("摁下了鼠標中鍵"); //}
3.射線檢測
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit;//檢測信息 if (Physics.Raycast(ray,out hit)) { print(hit.point); if (hit.collider.name == "Cube") { hit.collider.gameObject.GetComponent<MeshRenderer>().material.color = Color.red; } }
4.cube歲鼠標移動
public GameObject obj; Vector3 pos; bool b = false; // Use this for initialization void Start () { } // Update is called once per frame void Update () { // transform.LookAt(obj.transform); Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit;//檢測信息 if (Physics.Raycast(ray, out hit)) { if (Input.GetMouseButtonDown(0)) { pos = hit.point; transform.LookAt(new Vector3(pos.x, pos.y + 0.5f, pos.z));//lookat b = true; } } if (b) { transform.Translate(0,0,5*Time.deltaTime); if (Vector3.Distance(transform.position,pos)<1f) { b = false; print(123); } } }
5.
點擊cube隨機變顏色，掉下去 using System.Collections; using System.Collections.Generic; using UnityEngine; public class RayDiao : MonoBehaviour { GameObject obj; // Use this for initialization void Start () { } Color[] gameclor = { Color.black, Color.blue, Color.cyan, Color.green, Color.red, Color.yellow };//定義顏色數組 //Random num = new Random(); // Update is called once per frame void Update () { Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit;//檢查信息 if (Physics.Raycast(ray,out hit)) { if (Input.GetMouseButtonDown(0))//判斷是否點擊了鼠標左鍵 { if (hit.collider.tag.Equals("cube"))//判斷是否點擊的是cube { hit.collider.gameObject.GetComponent<MeshRenderer>().material.color = gameclor[Random.Range(0, gameclor.Length)];//隨機添加顏色 //hit.collider.gameObject.GetComponent<Rigidbody>().useGravity = true;//使添加的剛體激活 hit.collider.gameObject.AddComponent<Rigidbody>();//增加剛體 // obj= hit.collider.gameObject; } } } //if (obj != null)//不是空 //{ // obj.transform.Translate(0, -1*Time.deltaTime, 0);//以（-1*Time.deltaTime）的速度下降 //} } }
6.
添加cube的方法，如消消樂 using System.Collections; using System.Collections.Generic; using UnityEngine; public class creatCube : MonoBehaviour { //public GameObject cube; // Use this for initialization Color [] c = { Color.black, Color.blue, Color.clear, Color.cyan, Color.green, Color.red, Color.yellow }; void Start () { /* GameObject obj = Instantiate(Resources.Load("Cube")) as GameObject;*///另一種生成cube方法 //GameObject obj = Instantiate(cube);//第二種方式生成cube，需要預制體 //GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Cube);//生成cube // obj.transform.position = Vector3.one;//one表示坐標（1，1，1） //obj.transform.rotation = Quaternion.Euler(0, 45, 0);//角度設置 // obj.transform.localScale = new Vector3(2, 2, 2);//大小設置 //int index =obj.name.IndexOf("(");//字符串截取 //obj.name=obj.name.Substring(0, index); for (int i = 0; i<10; i++) { for (int j = 0; j < 10; j++) { GameObject obj = GameObject.CreatePrimitive(PrimitiveType.Cube);//生成cube obj.transform.position = new Vector3(i, j, 0);//生成位置 obj.transform.localScale = new Vector3(0.9f, 0.9f, 0.9f);//生成大小 obj.GetComponent<MeshRenderer>().material.color = c[Random.Range(0, c.Length)];//隨機顏色 } } } // Update is called once per frame void Update () { } }
7.
鼠標點擊變大 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit; if (Physics.Raycast(ray, out hit)) { if (hit.collider.gameObject.tag == "cube" &&Input.GetMouseButtonDown(0)) { cubeObj= hit.collider.gameObject; cubeObj.transform.localScale = new Vector3(1,1,1); } } if (Input.GetMouseButtonUp(0)&&cubeObj) { cubeObj.transform.localScale = new Vector3(0.9f, 0.9f, 0.9f); }
