Assume the Following Components Are Available: If You Want Any Others in Your
Banana Blowout
Last week we worked on a game called Banana Bash. Today, we put the polish on it by adding animation and some sounds.
The game is played as before, but with a few additions. 1) The monkey should do a little 8 frame hop. 2) If a coconut hits a monkey, it should split open across 3 frames. 3) When the monkey touches a coconut or a banana, it should play the appropriate sound.
Assume the following components are available: If you want any others in your
implementation, you will need to create them.
•monkey1.gif-monkey8.gif – these are the 8 frames of the monkey animation
•coconut1.gif-coconut3-gif - these are the 3 frames of the coconut breaking open
•bite.wav –the sound that should play when the monkey eats a banana
•cry.wav–the sound that should play when the monkey gets hit by a coconut
Modify the code from the banana bash game (reproduced below) to make the monkey dance!
