Lesson 2

Which statement is TRUE for non-waiting blocks?

• They allow the stack to continue even if the block's behavior is not yet complete.

• They pause the rest of the stack until that block's behavior has been completed.

• They cause the VR Robot to shut down.

• They are always blocks from the Looks category.

What do waiting blocks do in a VEXcode VR project?

• Repeat a behavior forever.

• Pause the stack until that block's behavior has been completed.

• Allow the stack continue even if the block's behavior is not yet complete.

• Set VR Robot Pen color to red.

How does the highlighting function help to visualize waiting vs. non-waiting blocks?

• It explains how to use waiting and non-waiting blocks.

• It stops the project when a waiting block is being executed.

• It moves blocks to show how the project is being executed.

• It highlights each block as it is being executed in a VEXcode VR project.

The [Wait until] block is a Control block that accepts Boolean values.

• True

• False

Which of the following describes the [Wait until] block?

• It will move to the next block while checking a Boolean condition.

• It will execute the next block after waiting 1 second.

• It will not move to the next block until the condition of the Boolean reports TRUE.

• It will stop the project completely.

How will the VR Robot behave once the Bumper Sensor is pressed in this example?

• The VR robot will stop driving.

• The VR Robot will turn right for 90 degrees.

• The VR Robot will drive forward.

• The project will restart.

What will the <Pressing bumper> block inside the [Wait until] block report in this example?

• Yes (bumper released) or No (bumper pressed).

• Drive forward (bumper pressed) or Drive in Reverse (bumper released).

• Turn right (bumper pressed) or Turn Left (bumper released).

• TRUE (bumper pressed) or FALSE (bumper released).

Which of these blocks can NOT be used as either a waiting or non-waiting block?

• [Stop driving]

• [Drive for]

• [Turn to heading]

• [Turn for]

Which of the following best describes how to create a project where the VR Robot drives forward until the Bumper Sensor is pressed?

• Select the [Drive] block, then place the [Turn for] and <Pressing bumper> blocks underneath.

• Select the [Drive] block, then place the [Wait until] block underneath. Place the <Pressing bumper> Boolean reporter block inside the hexagon in the [Wait until] block.

• Place the [Repeat until] block with the <Pressing bumper> Boolean after the [Drive] block.

• Place the [Drive for] block under the [When started] block. Add the <Pressing bumper> and the [Set drive heading] blocks.
