一些比较重要的函数

延迟执行某方法

void Start (){    

//重复调用  

 InvokeRepeating("LaunchProjectile", 1,5);//1秒后调用LaunchProjectile () 函数，之后每5秒调用一次    



//调用一次  

 Invoke("LaunchProjectile", 5);//5秒后调用LaunchProjectile () 函数  



//取消调用  

  CancelInvoke("LaunchProjectile");   

}    



void LaunchProjectile(){    

    print("hello");    

}  

协同程序

同步执行

//运行结果："Starting 0.0"和"Before WaitAndPrint Finishes 0.0"两句，2秒后打印"WaitAndPrint 2.0"  

//WaitAndPrint在Start函数内执行,可以视同于它与Start函数同步执行.  



void Start() {  

    print("Starting " + Time.time);  

    StartCoroutine(WaitAndPrint(2.0F));  

    print("Before WaitAndPrint Finishes " + Time.time);  

}  



IEnumerator WaitAndPrint(float waitTime){  

    yield return new WaitForSeconds(waitTime);  

    print("WaitAndPrint " + Time.time);  

}  

 执行完成后，执行下面的

//运行结果：0秒时打印"Starting 0.0",2秒后打印"WaitAndPrint 2.0"和"Done 2.0"  

// 运行WaitAndPrint直到完成。  



IEnumerator Start(){  

    print("Starting " + Time.time);  

    yield return StartCoroutine(WaitAndPrint(2.0F));  

    print("Done " + ime.time);  

}  



IEnumerator WaitAndPrint(float waitTime) {  

    yield return new WaitForSeconds(waitTime);  

    print("WaitAndPrint " + Time.time);  

}  

 同步执行

//StopCoroutine停止协同程序

IEnumerator Start() {

    StartCoroutine("DoSomething", 2.0F);

    yield return new WaitForSeconds(1);

    StopCoroutine("DoSomething");

}


IEnumerator DoSomething(float someParameter) {

    while (true) {

        print("DoSomething Loop");

        yield return null;

    }

}

 子/父级关系

设置子/父级关系

//B为A的父级

A.transform.parent = B.transform;

 获取所有子物体

foreach (Transform item in this.transform)

{

    print(item.name);

}

 旋转/角度

限制旋转角度

/// <summary>

/// 限制旋转角度 

/// </summary>

/// <param name="angle" />要旋转的Deg

/// <param name="min" />最小角度

/// <param name="max" />最大角度

/// <returns>符合标准的deg</returns>

public static float ClampAngle(float angle, float min, float max)

{

    if (angle < -360)

        angle += 360;

    if (angle > 360)

        angle -= 360;

    return Mathf.Clamp(angle, min, max);

}

 限制旋转最大扭距

/// <summary>

/// 限制旋转最大扭距 

/// </summary>

/// <param name="angleTarget">要达到的deg

/// <param name="angleNow">当前角度

/// <returns>符合标准的deg</returns>

public static float reviseMaxAngle(float angleTarget, float angleNow)

{

    float max = 160;

    float DValue = angleTarget - angleNow;



    if (DValue < -360)

        DValue += 360;

    if (DValue > 360)

        DValue -= 360;



    if (DValue > max)

    {

        DValue = max;

    }

    else if (DValue < -max)

    {

        DValue = -max;

    }

    angleTarget = angleNow + DValue;



    return angleTarget;

}

确定目标可见性(α透明)

bool isVisible = (gameCamera.isOrthoGraphic || pos.z > 0f) && (!disableIfInvisible || (pos.x > 0f && pos.x < 1f && pos.y > 0f && pos.y < 1f));
