Comp Sci L1 - Blocks with VEXcode VR Course Unit 4

Which block reports if the Bumper Switch is pressed?

• <Distance found object>

• <Pressing bumper>

• <Color near object>

• <Bumper switch on>

What values does the <Pressing bumper> block return?

• TRUE (pressed) or FALSE (released).

• Positive (pressed); Negative (released).

• Number values between one and ten.

• Distance from the object in millimeters (mm).

What will happen when the Bumper Sensor is pressed in this project?

• The VR Robot will turn left for 90 degrees.

• The VR Robot will stop moving.

• The VR Robot will turn right for 90 degrees.

• The VR Robot will drive in reverse for 200 millimeters (mm).

What does the <Pressing bumper> block report if the Bumper Sensor is pressed?

• Reports TRUE.

• Reports FALSE.

• Reports a measured distance.

• Reports an object found.

How could you use the Bumper Sensor in the Wall Maze challenge?

• To calculate the distances between the VR Robot and a wall.

• To instruct the VR Robot to turn when it bumps into a wall.

• To make the VR Robot ascend a wall to finish the maze faster.

• To determine the color of the wall.

What do non-waiting blocks do in a VEXcode VR project?

• They repeat a behavior forever.

• They skip the next block in the stack.

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

• They should only be used in an emergency.

Which statement is TRUE for waiting blocks?

• They wait for the user to select the "Step" button.

• They wait until the VR Robot has enough power to complete the task.

• They allow the rest of the stack to continue even if that block's behavior has not been completed.

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

What does the highlighting feature do when awaiting block is being executed?

• A highlight will appear around the block until the behavior is complete.

• It will change colors depending on whether the project is running a waiting or non-waiting block.

• It will move to the next block to show the next behavior in the project.

• A highlight will stay on the block until the entire project is complete.

What types of values does the [Wait until] block accept?

• Boolean values: TRUE or FALSE.

• Numeric values: one - ten.

• Color values.

• Time values.

How often will the [Wait until] block check a Boolean condition?

• It will check repeatedly until the Boolean reports FALSE.

• It will check repeatedly until the Boolean reports TRUE.

• It will check once every minute until the project is complete.

• It will check only once.
