CSC3150 Assignment 2
Task Description
In Assignment 2, you are required to complete the multithread program to implement the game “Frog crosses river”.
Game rules:
A river has logs floating on it, and a frog must cross the river by jumping on the logs as they pass by.
Objects:
Log: =================
Frog: 0
River bank: |||||||||||||||||||||
When the game starts, the frog stands in the middle of bottom bank of river. The user can control the frog
jumps by keyboards. The logs will move from left to right or right to left staggerly. Please take care of the edge
cases.
W: UP
S: Down
A: Left
D: Right
Q: Quit the game
You will win if the frog jumps to the other bank of river successfully.
You will lose if the frog lands in the river, or reaches the left/right side of the river.
Please note that this is a game. If the player suffers from extereme difficulty, high latency, and other
unexpected situations for a game, your grade will suffer as well.
Function Requirements (90 points):
To run the template, you will see the frog stands in the middle at bottom bank of river. There are 9 blank rows
which means the river. Compile the program to see the static output. (5 points)
You should complete the function named “logs_move” to let the logs can move staggerly from left to right or
from right to left. (20 points)
You should create pthread and use mutex lock for logs and frog movement control. (30 points)
“kbhit” function is provided for keyboard capture. You should complete the jump rules for keyboard actions.
And the frogʼs position should be updated when keyboard hits. (15 points)
When the logs are moving, the program should be able to judge the game status (win, lost or quit). Print out the
message for user whether he/she wins or lost the game. (15 points)
If the user quits the game, print the message. (5 points)
