使用一類

Question

我有此音板這是我的第一個項目和的mousePressed我很高興我能走到今天:)

不過，我試圖用mousePressed一類，它似乎不工作正確地說，我希望它能夠在點擊一次時播放，並在點擊兩次時停止播放。此時，當您將鼠標懸停在音板上的某個按鈕上時，它會自動播放聲音，直到您將其移至其他按鈕。

任何人都可以向我解釋這個問題嗎？

class sound{ 


    float x; 
    float y; 

    public sound(float x, float y) { 
    this.x = x; 
    this.y = y; 
    }

    mousePressed();

    } else

    s1.rewind(); 
    } 
    if (mouseX > 100 && mouseX < 199 
    && mouseY > 200 & mouseY < 299) {

Answer 1

你從你的草圖draw()函數調用你的Sound類的mousePressed()功能。你實際上並沒有檢查用戶是否按下了鼠標。

您可能只是想將這些調用移動到草圖的mousePressed()函數中。

Answer 2

void mousePressed(){ 
    if (mouseX > 1 && mouseX < 99 && mouseY > 1 && mouseY < 99) { 
     s2.play(); 
     image(p7, 1, 1); 
    }else { 
     s2.pause(); 
     s2.rewind(); 
     } 

我認爲這是問題，你檢查你的鼠標位置在哪裏，如果它不在那個位置，聲音會暫停。
