1、500 Lines or Less——可视化编程工具(Blockcode)该项目主要用于为龟图(turtle graphics)实现块语言，通过简单拖放创建图案，整个过程通过常用的Html、CSS和JavaScript来实现(每一个块由html元素组成，CSS用于设置样式，JavaScript时间处理器进行拖拽并修改参数)。其次，作者将块构建为一个框架以服务其他编程语言。▲操...
Visual representation of the drawing created using Turtle graphics. Example: Input values: 1. Move the turtle forward by 100 units 2. Turn the turtle left by 90 degrees 3. Move the turtle forward by 100 units 4. Turn the turtle left by 90 degrees ...

The first activity is, again, turtle graphics. A number of basic variations on drawing a rotated square are presented—without a lot of underlying explanation, initially—just to introduce the general concepts, but by the end of the section, you’ll have been provided with a pretty good unde...
