Adding Randomness to Pacman Game in Scratch

The video tutorial guides viewers through adding a ghost to a Pacman game, focusing on making the ghost move randomly within a maze. It covers setting the ghost's starting position, creating variables for direction and distance, and ensuring the ghost changes direction upon hitting walls. The tutorial emphasizes unpredictability in the ghost's movement and introduces programming concepts like subroutines to streamline code.

What is the primary goal when adding a ghost to the Pacman game?

• To make the ghost move faster than Pacman

• To ensure the ghost moves randomly and unpredictably

• To have the ghost start at a random position

• To make the ghost follow a fixed path

How do you ensure the ghost starts in the same position every game?

• By using a timer to reset the position

• By setting fixed coordinates for the ghost's starting position

• By allowing the player to choose the starting position

• By using a random number generator

What is the purpose of creating a variable for the ghost's direction?

• To determine the ghost's color

• To store a random number representing the ghost's direction

• To keep track of the ghost's score

• To store the ghost's speed

Why is it beneficial to use a subroutine for changing the ghost's direction?

• It reduces the game's memory usage

• It allows the ghost to change color

• It increases the ghost's speed

• It makes the code more readable and reusable

What is the purpose of setting a random distance for the ghost's movement?

• To make the ghost move in a straight line

• To make the ghost follow Pacman

• To ensure the ghost's movement is unpredictable

• To slow down the ghost

How do you prevent the ghost from moving through walls?

• By increasing the ghost's speed

• By using collision detection with the maze's color

• By setting a fixed path for the ghost

• By reducing the ghost's size

What happens if the ghost hits a wall during its movement?

• It speeds up

• It changes direction

• It moves through the wall

• It stops moving

Why might you need to adjust the random distance range for the ghost's movement?

• To make the ghost's movement smoother

• To change the ghost's color

• To increase the game's difficulty

• To make the ghost move slower

What is the effect of setting a high maximum distance for the ghost's movement?

• The ghost becomes invisible

• The ghost moves in a predictable pattern

• The ghost might stop over gaps

• The ghost moves too slowly

What is the next step after ensuring the ghost moves unpredictably?

• Adding more ghosts to the game

• Changing the ghost's color

• Making the ghost faster than Pacman

• Allowing the ghost to interact with Pacman
