介绍

VEXcode VR 包含一个监视器选项卡，可以在项目运行时显示控制台输出、监视变量和监视传感器值。

控制台方法可以显示文本、数字和变量值。它们还可以将控制台光标移动到新的一行、清除控制台以及设置更改颜色后打印文本的颜色。

以下是所有方法的列表：

打印 — 输出文本或清除控制台。

• print — Displays text, numbers, or variable values in the Console.

• new_line — Moves the Console cursor to the start of the next row.

• set_print_color — Sets the color used for text printed in the Console.

• clear — Clears all rows in the Console.

监控 — 在 VEXcode 的“监控”选项卡中，监控项目期间传感器或变量的值。

• monitor_variable — Adds one or more predefined variables to the Monitor tab.

• monitor_sensor — Adds one or more sensor values to the Monitor tab.

打印

print

print displays text, numbers, or variable values in the Console using the current cursor position.

如果您希望打印消息中包含项目中的值（例如分数、计时器或传感器读数），请使用自定义字符串格式。有关更多信息，请参阅字符串格式页面。

Use new_line when you want the next printed value to start on a new row.

Usage:
brain.print(value, precision)

参数	描述
value	要在控制台中显示的文本、数字或变量值。
precision	Optional. The number of decimal places to display when printing a number. The default is 0, so numbers print with no decimal places.

def main():
    # Display a message in the Console
    brain.print("Hello, robot!")

# VR threads — Do not delete
vr_thread(main)

def main():
    # Print a number with 5 decimal places
    brain.print(math.pi, precision=5)

# VR threads — Do not delete
vr_thread(main)

new_line

new_line moves the cursor to column 1 on the next row in the Console. The next value printed will appear on that row.

当您希望下一个打印值从新的一行开始时，请使用此方法。

Usage:
brain.new_line()

参数	描述
	此方法没有参数。

def main():
    # Print on two lines
    brain.print("Row 1")
    brain.new_line()
    brain.print("Row 2")

# VR threads — Do not delete
vr_thread(main)

set_print_color

set_print_color sets the color used for text printed in the Console after this method is used. At the start of a project, the Console text color is set to BLACK.

Usage:
brain.set_print_color(color)

参数	描述
color	The color to use for text printed in the Console: BLACK BLUE GREEN RED

def main():
    # Print text in different colors
    brain.print("Default text color")
    brain.new_line()
    brain.set_print_color(RED)
    brain.print("Red text color")

# VR threads — Do not delete
vr_thread(main)

clear

clear clears all rows from the Console.

Usage:
brain.clear()

参数	描述
	此方法没有参数。

def main():
    # Display text, then clear it after two seconds
    brain.print("This will disappear...")
    wait(2, SECONDS)
    brain.clear()

# VR threads — Do not delete
vr_thread(main)

监视器

monitor_variable

monitor_variable adds one or more predefined variables to the Monitor tab in VEXcode. This lets you watch a variable’s value change while a project is running.

Variables must be global for monitor_variable to monitor them successfully. Provide each variable name as a string.

Usage:
monitor_variable(“variable”)
monitor_variable(“variable1”, “variable2”)

参数	描述
variable	要监控的预定义全局变量的名称，以字符串形式给出。要监控多个变量，请用逗号分隔每个变量名。

def main():
    # Monitor the amount of loops
    global loops
    monitor_variable("loops")

    # Drive in a square 3 times
    for loops in range(12):
        drivetrain.turn_for(RIGHT, 90, DEGREES)
        drivetrain.drive_for(FORWARD, 150, MM)

# VR threads — Do not delete
vr_thread(main)

actions = 0

def main():
    # Monitor the amount of loops and actions
    global loops, actions
    monitor_variable("loops", "actions")

    # Drive in a square 3 times
    for loops in range(12):
        drivetrain.turn_for(RIGHT, 90, DEGREES)
        drivetrain.drive_for(FORWARD, 150, MM)
        actions = actions + 2

# VR threads — Do not delete
vr_thread(main)

monitor_sensor

monitor_sensor adds one or more sensor values to the Monitor tab in VEXcode. This lets you watch sensor values change while a project is running.

如果传感器可以以不同的单位返回数据，“监控”选项卡将显示以每种可用单位返回的数据。请以字符串形式提供每个传感器值。

Usage:
monitor_sensor(“sensor”)
monitor_sensor(“sensor1”, “sensor2”)

参数	描述
sensor	The sensor value to monitor, given as a string. To monitor more than one sensor value, separate each sensor value with a comma. This can be any sensor method that returns a value, such as “drivetrain.rotation”.

def main():
    # Monitor the distance in MM and inches
    monitor_sensor("front_distance.get_distance")
    drivetrain.drive_for(FORWARD, 400, MM)

# VR threads — Do not delete
vr_thread(main)

def main():
    # Monitor the rotation in the Monitor tab
    monitor_sensor("drivetrain.rotation", "drivetrain.heading")
    drivetrain.turn_for(RIGHT, 450, DEGREES)

# VR threads — Do not delete
vr_thread(main)
