Alice: Slot Machine
Concepts Need:
random numbers
nested if statements
object parameters in methods
Slot Machine Problem - Phase 1
Create an Alice program that will simulate a slot machine. The slot machine will have three “wheels” that will "display" the numbers from 1 to 6. The numbers are displayed by changing the colour of the "wheels".
Required Objects:
one "wheel"
3D-Text for the players name
3D-Text for the number Tokens
a lever
Your program will take as input:
the player’s name
the number of tokens in the player’s bank (there will be at least one and fewer than 100)
Your program will out
number of times the player plays
the player's name
the number of tokens in the player's bank
First
- when the world starts
- prompt for the player's name
- prompt for the number of tokens
- when the lever is clicked
- call a world class method to change the colour of one "wheel" as the random number changes
Slot Machine Problem – Phase 2
Objects to Add:
two more wheels
Modify your Phase 1 Slot Machine program, so that you will use one method to spin all the wheels of the slot machines. This will be accomplished by creating a method that uses an object as a parameter. For a sample program see 008AliceTips-ObjectsAsParameters in 1.1 Alice Programs: Tips and Tricks
Convert your world class method to change the colour of one "wheel" to use object parameters.

The machine will pay:
10 to 1 if all three wheels match
5 to 1 for two matching wheels.
Logic Method #1
if all three wheels are the same colour
pay 10
else
if wheel 1 and wheel 2 are the same colour
pay 5
if wheel 2 and wheel 3 are the same colour
pay 5
if wheel 1 and wheel 3 are the same colour
pay 5
Logic Method #2
if wheel 1 and wheel 2 are the same colour
if wheel 2 and wheel 3 are the same colour
pay 10
else
pay 5
else
if wheel 2 and wheel 3 are the same colour
pay 5
if wheel 1 and wheel 3 are the same colour
pay 5
