Debugging a Racing Game Prototype

The video tutorial focuses on debugging a racing game prototype. The game involves two cars racing on a straight track, and the goal is to identify and fix bugs in the display function. The instructor demonstrates how to test the display function with various test cases, identifies issues with car positions, and updates the function to handle cases where cars are at the same position. The tutorial concludes with advice on narrowing down bugs to individual functions for easier debugging.

What is the main objective of the racing game prototype?

• To have the cars remain stationary

• To have the cars race on a straight track and determine the winner

• To have the cars race in a circular track

• To have the cars move backward on the track

What was the initial observation about the game that indicated a bug?

• The cars were not starting the race

• The cars were moving in reverse

• The cars were disappearing from the track

• The cars were moving too slowly

What does the display function take as input?

• The positions of the cars and the length of the track

• The color of the cars

• The speed of the cars

• The names of the cars

Which test case was NOT mentioned for the display function?

• Both cars at the same position

• Second car ahead

• First car ahead

• Cars moving backward

What was the solution to the bug where a car's position exceeded the track length?

• Continue drawing until the furthest position is reached

• Ignore the car's position

• Reset the car's position to the start

• Stop the game immediately

What symbol was initially chosen to represent both cars on the same position?

• A

• B

• X

• O

What was the issue with the initial implementation of the 'X' symbol?

• It was not visible on the track

• It was drawn for every segment

• It was too small to see

• It was the wrong color

What condition must be met to draw an 'X' for both cars on the same position?

• The cars must be at different positions

• The cars must be at the start of the track

• The current position must match both car positions

• The cars must be at the end of the track

What is the recommended approach when encountering a bug in a program?

• Ask someone else to fix it

• Ignore the bug and continue

• Narrow it down to the individual function level

• Rewrite the entire program

What was the final outcome after fixing the bugs in the display function?

• The cars stopped moving

• The game crashed

• The display function worked correctly

• The game still had issues
