The Pen Down 积木 is a 画笔类积木 and a 条形积木. The block will make its 角色 continuously pen a trail wherever it moves (until the 停笔 block is used). The color, width, and shade of the trail can be changed with other independent blocks.
This block is used most frequently in projects that require art to be drawn. When a sprite will continuously pen a trail (for example, a 专案 where the goal is to fill the whole screen), most projects will use this block. This block is also commonly used in 一角色一脚本类专案 projects.
