VEX VR - Python: Units 1-4

Unit 1: Colorization of Code in VEXcode VR Python

The Importance of Indentation

Improper indentation can result in a project not executing as intended, or not at all.

​

​

​

​

​

Commands that are aligned with one another will run as a sequence. Commands that are indented within other commands (like the commands inside of a loop) will run within that structure.​

Multiple Choice

How far will the VR Robot move based off the command below?

drivetrain.drive_for(FORWARD, 300, MM)

• 200mm

• 400mm

• 500mm

• 300mm

Multiple Choice

What part of the command do you change to adjust the direction of the drive_for command?

• 1

• 2

• 3

• 4

Multiple Choice

How will the VR Robot move based off of the command above?

• Turn left to a heading of 80 degrees.

• Turn right to a heading of 90 degrees.

• Turn left for 90 degrees.

• Turn right for 80 degrees.

Multiple Choice

Why is it important to correctly sequence commands in a project?

• To make a project that works as intended.

• To make the VR Robot skip around to random commands.

• To have accurate values and parameters in commands.

• To make a project that does not work as intended.

Multiple Choice

 What order will the buildings on the Castle Crasher Playground be knocked over according to this project above?

• 1, 2, 3, 4, 5

• 3, 2, 5, 4, 1

• 3, 1, 4, 5, 2

• 5, 2, 1, 4, 3

Multiple Choice

Which of the following should be the first command in a project so the VR Robot moves the pen down to draw a black line?

• The drive_for command with the parameter set to 2000 millimeters (mm).

• The turn_for command with the parameter set to 90 degrees.

• The move command with the parameter set to “DOWN".

• The move command with the parameter set to "UP".

Multiple Choice

Which of the following commands is used to change the color of the pen?

• set_pen_color

• move

• turn_for

• for loop

Multiple Choice

How many times will the for loop repeat the turn_for and drive_for commands inside of it?

• 1

• 2

• 3

• 4

Multiple Choice

What is the condition that will end this for loop?

• After the VR Robot places the pen down.

• After the VR Robot drives forward one time for 200 millimeters (mm).

• After the for loop has repeated the commands inside of it four times.

• After the VR Robot has driven forward 200 millimeters (mm) then turned right 60 degrees six times.

Multiple Choice

How can the following example be simplified by using a for loop?

• By placing the first two drive_for and turn_for commands in a for loop that repeats four times.

• By placing the drive_for command in a for loop that repeats four times.

• By placing the turn_for command in a for loop that repeats four times.

• By changing all of the parameters of the drive_for commands to 400 MM instead of 200 MM.

Multiple Choice

Which behaviors will be repeated as part of the for loop in this project?

• Moving the pen down

• Setting the pen color to red, driving forward 200mm, and turning right 45 degrees

• Moving the pen up, setting the pen color to blue, and turning right for 90 degrees

• Turning right for 45 degrees, moving the pen down, and driving forward for 200mm

Multiple Choice

The following project was created to draw a house, but it is unfinished. Which of the following commands should be used next to begin drawing the triangular roof of the house?

• move command set to "UP"

• drive_for command set to drive forward 2000 millimeters (mm)

• for loop with the range function set to six

• turn_for command set to turn left 135 degrees
