p5Play Project Golf & Helicopter Midterm Review w/ Annotations

Front

What does the following code achieve in the game loop?
obstacle.move(-SPEED, 0);

Back

Moves the obstacle horizontally from right to left.

Answer explanation

The code 'obstacle.move(-SPEED, 0);' moves the obstacle horizontally by a negative value of SPEED, which translates to moving it from right to left on the screen. Thus, the correct answer is that it moves the obstacle horizontally from right to left.

Front

Which condition ensures that the obstacle resets to the right side of the screen after hitting the left side?

Back

Front

What does the clicking Boolean variable do in this project?

Back

It determines whether the helicopter should move upward or downward.

Answer explanation

The clicking Boolean variable is crucial as it determines the helicopter's movement direction. When true, it allows the helicopter to move upward, while false would typically mean it moves downward.

Front

How does the value of dy change as the game loop runs?

Back

dy increases or decreases each time through the game loop based on conditions.

Answer explanation

The correct choice is that dy increases or decreases each time through the game loop based on conditions. This means dy is dynamic and can change depending on the game's state, rather than being constant or reset.

Front

What is the purpose of the MAX_DY constant in the game?

Back

It ensures the helicopter’s vertical speed does not exceed a certain limit.

Answer explanation

The MAX_DY constant is crucial as it limits the helicopter's vertical speed, preventing it from moving too fast and ensuring smoother gameplay. This helps maintain control and enhances the player's experience.

Front

Which condition ensures the helicopter stays within the screen boundaries?

Back

Front

How is the “You Lose” message displayed when the helicopter hits the top or bottom of the screen?

Back

Front

Which function is used to stop the game timer after the helicopter hits a wall?

Back

stopTimer();

Answer explanation

The function stopTimer(); is specifically designed to halt the game timer, making it the correct choice when the helicopter collides with a wall. The other options do not serve this purpose.

Front

What happens when the helicopter collides with an obstacle?

Back

The “You Lose” message is displayed, and the game timer stops.

Answer explanation

When the helicopter collides with an obstacle, the game ends, displaying a "You Lose" message and stopping the game timer, indicating that the player can no longer continue.

Front

What best describes the behavior of the game at this stage? Options: The helicopter moves vertically only, and obstacles stay static. The helicopter moves based on clicking, obstacles move right to left, and the game ends when the helicopter hits a wall. The helicopter and obstacles move randomly across the screen. The helicopter and obstacles only reset positions after colliding.

Back

The helicopter moves based on clicking, obstacles move right to left, and the game ends when the helicopter hits a wall.

Answer explanation

The correct choice describes that the helicopter moves based on clicks, obstacles move from right to left, and the game ends upon collision with a wall, accurately reflecting the game's mechanics at this stage.
