这款VR机器人使用一支笔在游乐场上边移动边作画。机器人的笔可以改变粗细、颜色，并能覆盖整个游乐场。

以下是所有可用模块的列表：

操作——改变画笔状态以及游乐场和其他图画的填充颜色。

• move – Raise or lower the robot’s pen.

• fill – Fill a playground or an enclosed area with a specified color.

修改器 – 修改画笔的颜色和粗细。

• set_pen_color – Set the color of the robot’s pen from preset options.

• set_pen_width – Set the width of the robot’s pen.

• set_pen_color_rgb – Set the color of the robot’s pen with red, green, and blue values.

行动

move

move sets the position of the VR Pen.

Usage:
pen.move(action)

参数	描述
action	The set position of the VR Pen: DOWN – Allows the pen to draw on the playground. UP – Stops the pen from drawing on the playground.

def main():
    # Draw a straight line.
    pen.move(DOWN)
    drivetrain.drive_for(FORWARD, 400, MM)

# VR threads — Do not delete
vr_thread(main)

fill

fill fills in the shape of whatever the VR Pen is on top of, for example:

网格线	网格方块	在没有网格的操场上，它会铺满整个操场地面。

Usage:
pen.fill(red, green, blue, opacity)

参数	描述
red	RGB 值中红色颜色的强度，范围从 0 到 255。
green	RGB 值中绿色的强度，范围从 0 到 255。
blue	RGB 值中蓝色的强度，范围从 0 到 255。
opacity	VR笔颜色的透明度，范围从0%到100%。

def main():
    # Fill the playground's floor with blue at full opacity.
    pen.fill(43, 162, 202, 100)
