c# - Unity でスクリプトを使用してスプライトのアルファを変更する方法

Question

4 つのボタンがあり、ボタンを押すとそれぞれが点滅します。ただし、ボタンを押す場合、ボタンが暗い (点滅している) 間に別のボタンをクリックすると、そのボタンは暗いままになります。無効にする前にスプライトの色をリセットしたいのですが、うまくいきません。ボタンを押しても点滅しなくなりました....

コードは次のとおりです。

void Start () {
        easy.GetComponent<SpriteRenderer>().color = color;
    }

    void Update () {
        if(difficultySelected[0] == true){
            enemyBehavior.shotsPerSecond = 0.2f;
            //Enabling the selected button
            easy.enabled = true;

            //Reseting the colors
            normal.GetComponent<SpriteRenderer>().color = color;
            hard.GetComponent<SpriteRenderer>().color = color;
            expert.GetComponent<SpriteRenderer>().color = color;

            //Disabling the 'unselected' buttons
            normal.enabled = false;
            hard.enabled = false;
            expert.enabled = false;

            easy.Play("Difficulty");
        }else if(difficultySelected[1] == true){
            enemyBehavior.shotsPerSecond = 0.5f;
            normal.enabled = true;

            easy.GetComponent<SpriteRenderer>().color = color;
            hard.GetComponent<SpriteRenderer>().color = color;
            expert.GetComponent<SpriteRenderer>().color = color;

            easy.enabled = false;
            hard.enabled = false;
            expert.enabled = false;

            normal.Play("Difficulty");
        }else if(difficultySelected[2] == true){
            enemyBehavior.shotsPerSecond = 1;
            hard.enabled = true;

            easy.GetComponent<SpriteRenderer>().color = color;
            normal.GetComponent<SpriteRenderer>().color = color;
            expert.GetComponent<SpriteRenderer>().color = color;

            easy.enabled = false;
            normal.enabled = false;
            expert.enabled = false;

            hard.Play("Difficulty");
        }else if(difficultySelected[3] == true){
            enemyBehavior.shotsPerSecond = 2;
            expert.enabled = true;

            easy.GetComponent<SpriteRenderer>().color = color;
            normal.GetComponent<SpriteRenderer>().color = color;
            hard.GetComponent<SpriteRenderer>().color = color;

            easy.enabled = false;
            normal.enabled = false;
            hard.enabled = false;

            expert.Play("Difficulty");
        }
    }

あなたは書ける：

color.a = 1f; // value between 0 and 1, where 1 is opaque

//Resetting the colors
normal.GetComponent<SpriteRenderer>().color = color;
hard.GetComponent<SpriteRenderer>().color = color;
expert.GetComponent<SpriteRenderer>().color = color;
