javascript - 将图像加载到Processingjs中的绘制循环中

Question

我的蜜蜂不会出现。在绘图循环中加载和显示图像的正确方法是什么？

/* @pjs preload="/static/uploaded_resources/p.8706/Flower-Ice-icon.png"; */
/* @pjs preload="/static/uploaded_resources/p.8706/bee.png"; */
void setup() {  // this is run once.   

    PImage img;
    PImage bee;
    // set the background color
    background(255);

    // canvas size (Variable aren't evaluated. Integers only, please.)
    size(256, 256); 

    img = loadImage("/static/uploaded_resources/p.8706/Flower-Ice-icon.png");
    bee = loadImage("/static/uploaded_resources/p.8706/bee.png");
    image(img, 0, 0);
} 
void draw() {  // this is run repeatedly.  
    image(bee, mouseX, mouseY);
}

Pjs 不支持使用多个预加载。相反，您需要用逗号分隔这两个图像作为单个预加载命令的参数。请参阅http://processingjs.org/reference/preload , “多个图像的语法”
