You want your frog sprite to face left when moving left and right when moving right. Which rotation style should you set?
All-around allows spinning any direction
Left-right flips to face left or right
Don't rotate keeps sprite always upright
Random rotate changes direction each step
Which condition correctly checks edge contact before saying a message?
If backdrop switches then say message
If key space pressed then say message
If touching edge then say message
If touching mouse-pointer then say message
A program shows the frog life cycle using sprites for eggs, tadpole, froglet, and adult frog. What is a good plan to animate the stages?
Randomly change to any costume every frame
Switch costumes in order with timed waits
Use forever to move and bounce each stage
Show all stages at once without movement
