与拖拽角色相关的积木

先修科目
介绍
如果想运用拖拽事件,你需要用事件类别的这3个帽子积木:“二维拖动开始时”、“被二维拖动的时候”、“二维拖动停止时”。

全屏拖拽模式
默认情况下,在全屏模式不能拖拽角色。
如果想在全屏舞台上拖拽角色,必须用侦测类别中的积木”将拖动模式设为( )"

然后从下拉菜单中选择“可拖动”。
使用方法如下:

积木:“二维拖动开始时”
当你开始拖拽角色时,就会触发这个积木。例如,当我们开始拖拽小狗时,可以让小狗换成闭着眼睛的造型。

积木:“被二维拖动的时候”
当你在舞台上拖拽角色(仅全屏模式),这个积木会重复不断地运行。

积木:“二维拖动停止时”
当你停止拖拽角色并松开鼠标时,这个积木就会运行。在如下示例中,每当我们停止拖拽,就让小狗回到舞台中心。
