blockRendering.Drawer.draw() 方法
将砌块绘制到工作区。这里是“绘图”表示设置 SVG 路径元素并在屏幕上移动字段、图标和连接。
路径片段被推送到“steps”数组中,这些“路段”数组随后与空格连接,并直接在块上设置。这可保证这些步骤用空格分隔以提高可读性,但这并不是强制性要求。
Signature:
draw(): void;
返回:
void

This involves setting SVG path elements and positioning fields, icons, and connections. The method constructs the block's path by pushing path segments into \"steps\" arrays. These steps are then joined with spaces and assigned directly to the block. The method does not take any arguments and does not return anything.\n"]]
