If you want to stop the Sprite when it reaches the edge, which of this code is correct?

• 
• 
• 
• None of these

Answer explanation

The "repeat until" block is a control block that repeats a set of code until a specified condition becomes true. The code is executed repeatedly until the condition is satisfied. So when the Sprite reaches the edge it will stop.

Where does the sprite end up after the script has been run?

• 1. (X:200,Y:10)

• 1. (X:220,Y:0)

• 1. (X:0,Y:0)

• (X:220,Y:220)

Answer explanation

 We have used the condition of greater than 200 Inside the repeat until loop. So the loop will get executed until the x position will not get more than 200, after that it will stop.

How does changing the backdrop continuously create the illusion of sprite movement?

• 1. The sprite is physically moved around the screen
