Question

我已经尝试了所有工作来使这个工作以硬编码数字结束，但当我鼠标悬停在舞台上时根本没有任何事情发生。鼠标悬停（或鼠标移动）仅在我实际覆盖图像本身时才会激活。每当我将鼠标移到舞台上时，有人能告诉我如何使图像向左或向右移动吗？

stage.on('mouseover', function(){ var mousePos = stage.getUserPosition(); if (mousePos.x >= 289) { rect.move(5, 0); } else { rect.move(-5,0); } stage.add(layer); });

当我们在图像之前添加矩形（透明）时，KineticJS Moverover正在工作。请参阅以下代码，其工作情况。

            y: stage.getHeight() / 2 - 59,
            image: imageObj,

              width: stage.getWidth(),
              height: stage.getHeight()

          layer.add(rect);
          layer.add(yoda);
          stage.add(layer);

          stage.on('mousemove', function(){ 
            var mousePos = stage.getUserPosition(); 
            if (mousePos.x >= 289)

              yoda.move(5, 0);
            } 
            else 
            { 
              yoda.move(-5, 0);
            } 
            layer.draw();
