Lab Exercises, 6 March
-
(Lab6MarchEx1.a2w) Create a world with a frog (Animals) and a ladybug (Animals). Write an interactive program to allow the user to drag the ladybug around the scene. (Use a let the mouse move objects event.) As the ladybug is dragged around, make the frog chase after it by moving one hop at a time. If the user moves the ladybug within 2 meters of the frog, have the frog look at the camera and say "ribbit" -- then end the animation.
-
(Lab6MarchEx2.a2w) Extend the world you created in the previous exercise with the following steps. The structure of this solution is very similar to what we built for Homework 5.
- Count the number of hops the frog makes.
- If the number of hops reaches 5 before the frog gets within 2 meters of the ladybug:
- Make the frog's head turn to face the camera, and have the frog say, "Whew! I'm tired."
- Start counting over from 0.
- The frog should continue hopping after the ladybug, stopping to take a break only every 5 hops.
