Introduction & Learning Objectives

Learning Objectives Identify at least three types of challenges that can be added to a game (e.g., obstacles, timers, score goals). Explain how a conditional (IF-THEN statement) is used to create a challenge. Use an event block to trigger a challenge, like a character touching an obstacle. Create a simple moving obstacle that affects the player. Implement a countdown timer that ends the game. Design a game rule that makes winning more difficult but fair.

REPEAT UNTIL <timer = 0>: WAIT 1 second, CHANGE timer by -1. Use this pattern at the start of the game. It creates a variable for time, sets a starting value, and then counts down every second until it reaches zero, which can then trigger a 'Game Over' event. The Winning Goal Pattern IF <score = 10> THEN <show 'You Win!' screen> This pattern checks if the player has reached the winning score. You can put this inside a...
