创建协程以淡出不同类型的对象

Uri*_*pov 2 c# unity-game-engine

嗨,我正在尝试统一创建一个协程,以处理各种物体上的褪色。到目前为止,我已经能够获得所需的不同类型的Alpha值,但是在使用新颜色后如何设置它还处于死胡同。这是我的代码:

public static  IEnumerator FadeTo(float aValue, float aTime,GameObject gameObj)
            {
                Component[] allComponents = gameObj.GetComponents(typeof(Component));
                Component fadableComponent;
                Type type = null;
                float alpha=0;
                foreach(Component c in allComponents)
                {
                    if(c.GetType()==typeof(Image))
                    {
                        fadableComponent = c;
                        alpha = fadableComponent.GetComponent<Image>().color.a;
                        type = fadableComponent.GetType();
                        Debug.Log("Found a image");
                        break;
                    }
                    if (c.GetType() == typeof(Renderer))
                    {
                        fadableComponent = c;
                        alpha = fadableComponent.GetComponent<Renderer>().material.color.a;
                        type = fadableComponent.GetType();
                        break;
                    }
                    if (c.GetType() == typeof(SpriteRenderer))
                    {
                        fadableComponent = c;
                        alpha = fadableComponent.GetComponent<SpriteRenderer>().color.a;
                        type = fadableComponent.GetType();
                        break;
                    }
                    if(c.GetType()== typeof(CanvasGroup))
                    {
                        fadableComponent = c;
                        alpha = fadableComponent.GetComponent<CanvasGroup>().alpha;
                        type = fadableComponent.GetType();
                    }
                    Debug.Log(alpha.ToString());
                }


                for (float t = 0.0f; t < 1.0f; t += Time.deltaTime / aTime)
                {
                    Color newColor = new Color(1, 1, 1, Mathf.Lerp(alpha, aValue, t));
                    gameObj.transform.GetComponent(type) // What now ?!
                    yield return null;
                }
                yield return null;
            }
        }

现在,我知道如何使用另一组if或not进行操作,但是我想避免这种情况。以我想避免的解决方案为例,我介绍了iTween实现。这是我要避免的完美示例:

if(target.GetComponent<GUITexture>()){
            target.GetComponent<GUITexture>().color=colors[3];
        }else if(target.GetComponent<GUIText>()){
            target.GetComponent<GUIText>().material.color=colors[3];
        }else if(target.GetComponent<Renderer>()){
            target.GetComponent<Renderer>().material.color=colors[3];
        }else if(target.GetComponent<Light>()){
            target.GetComponent<Light>().color=colors[3];   
        }

妈妈,这是一团糟。延长这将是一场噩梦。

基本语法是

所以(用伪代码)

StartCoroutine( 2f.Tweeng( .. move the ball .. ) );
StartCoroutine( .5f.Tweeng( .. spin the spaceship .. ) );
StartCoroutine( 1f.Tweeng( .. fade the text .. ) );

这些例子是

  • 在1/2秒内旋转飞船
  • 淡出文本一秒钟。

// tweeng z to 20 degrees in .12 seconds
StartCoroutine(.12f.Tweeng( (t)=>transform.Eulers(0f,0f,t), 0f,20f) );

// fade in alpha in .75 seconds
StartCoroutine(.75f.Tweeng( (u)=>{c.a=u;s.color=c;}, 0f,1f) );

// duck volume..

您可以补间任何东西,当然包括淡入淡出。

Tweeng的基本代码库:

只需将其放在文件Extns.cs中:

public static class Extns
    {
    public static IEnumerator Tweeng( this float duration,
               System.Action<float> var, float aa, float zz )
        {
        float sT = Time.time;
        float eT = sT + duration;

        while (Time.time < eT)
            {
            float t = (Time.time-sT)/duration;
            var( Mathf.SmoothStep(aa,zz, t) );
            yield return null;
            }

        var(zz);
        }

    public static IEnumerator Tweeng( this float duration,
               System.Action<Vector3> var, Vector3 aa, Vector3 zz )
        {
        float sT = Time.time;
        float eT = sT + duration;

        while (Time.time < eT)
            {
            float t = (Time.time-sT)/duration;
            var( Vector3.Lerp(aa,zz, t) );
            yield return null;
            }

        var(zz);
        }
}
