    # Set the color to orange at full opacity.
    pen.set_pen_color_rgb(225, 112, 52, 100)
    # Drive forward for 400 MM to draw a line.
    drivetrain.drive_for(FORWARD, 400, MM)

pen.fill()

The pen.fill(red, green, blue, opacity) method fills in the shape of whatever the VR Pen is on top of, for example:

网格线	网格方块	在没有网格的游乐场上，它填满了整个游乐场地板。

这是一种非等待方法，允许任何后续方法无延迟地执行。
