Question

Paper.js遇到很多问题。在Udemy上做Colt Steele的Web Developer Bootcamp。我在第19节。目前正在尝试制作Patatap克隆。在我被困的时候：

HTML

<!DOCTYPE html>
<html>
<head>
    <title>Circles</title>
    <link rel="stylesheet" type="text/css" href="circles.css">
    <script src="https://cdnjs.cloudflare.com/ajax/libs/paper.js/0.10.3/paper-full.min.js"></script>

    <script type="text/paperscript" canvas="myCanvas">

    function onKeyDown(event) {
        var maxPoint = new Point(view.size.width, view.size.height);
        var randomPoint = Point.random();
        var point = maxPoint * randomPoint;
        new Path.Circle(point, 10).fillColor = "olive";
    }

    var animatedCircle = new Path.Circle(new Point(300,300), 100);
    animatedCircle.fillColor = "red";

    }

    </script>
</head>
<body>
    <canvas id="myCanvas" resize></canvas>

</body>
</html>

CSS

canvas {
    width: 100%;
    height: 100%;
    background: black;
}

body, html {
 height: 100%;
 margin: 0;
}

Chrome控制台错误

应该发生什么，只是显示一个圆圈。那就是它。

Answer 1

通过将稿件替换为下面，它可行。首先，删除不必要的结束标记}。其次，将animateCircle修复为animatedCircle。

    <script type="text/paperscript" canvas="myCanvas">
    function onKeyDown(event) {
        var maxPoint = new Point(view.size.width, view.size.height);
        var randomPoint = Point.random();
        var point = maxPoint * randomPoint;
        new Path.Circle(point, 10).fillColor = "olive";
    }

    var animatedCircle = new Path.Circle(new Point(300,300), 100);
    animatedCircle.fillColor = "red";
    </script>
