垃圾分类
垃圾分类已经成为我们日常生活中很重要的一部分,这对于环境保护、资源回收利用具有重要意义。
下面我们做一个简单的垃圾分类互动游戏。
1. 准备工作
(1)导入背景库中的“Mural”,并编辑该背景,增加如下图中的两个垃圾桶,注明“可回收垃圾”和“不可回收垃圾”的文字说明;
(2)导入角色库中的“Takeout”作为一种纸袋垃圾。
2. 功能实现
(1)点击绿旗后,地面出现垃圾“Takeout”(造型a),垃圾出现的位置不与垃圾桶相接触,垃圾静止1秒。
(2)垃圾面向鼠标指针移动。
(3)当垃圾遇到绿色的可回收垃圾桶时消失,并说“分类正确”2秒:当垃圾遇到蓝色的不可回收垃圾桶不会消失,并说“分类错误”2秒。
3. 设计思路与实现
(1)角色分析
- 角色:Takeout
(2)背景分析
- 背景:Mural(在上面绘制两个垃圾桶)
(3)所用积木块介绍
