• 00:34

• 01:47

• 02:59

What is the first block used to make the object move? (01:09–01:47)

• "Move 10 steps"

• "Set X to"

• "Point in direction"

• "If on edge bounce"

How is the ball made to bounce when it hits the edges of the screen? (01:47–02:27)

• By using the "move 10 steps" block

• By using the "if on edge bounce" block

• By changing the X position

• By clicking the green flag

What does the "point in direction" block do? (01:47–02:27)

• Changes the speed of the object

• Sets the direction the sprite moves

• Stops the ball from moving

How does the paddle follow the mouse movement? (03:35–04:15)

• By linking the "set X to" block with the "mouse X" block
