Conditional Games

Learning Objectives Design a game that uses a state variable to track progress (e.g., 'start', 'playing', 'win'). Write nested conditional statements (an IF inside another IF) to handle multi-step logic. Use compound conditionals with 'AND' to check if two or more conditions are true at the same time. By the end of a this lesson, students will be able to use compound conditionals with 'OR' to check if at least one of several conditions is true. Construct an 'IF...ELSE IF...ELSE' chain to choose between multiple possible outcomes. Debug a simple game by tracing the logic of its conditional statements. Ever played a game where you need a key AND to be at the right door to open it? How does the computer know to check f...

TermDefinitionExample Nested ConditionalAn IF statement that is placed inside another IF statement. The inner check only happens if the outer check is true.IF you have a ticket, THEN { IF you are on the right train, THEN you can ride. } Compound Conditional (AND)A single IF statement that checks if two or more conditions are true at the same time. All conditions must be true for the code to run.IF player_score > 100 AND player_level == 5, THEN unlock the boss level. Compound Conditional (OR)A single IF statement that checks if at least one of two or more conditions is true. Only one condition needs to be true for the code to run.IF has_magic_key OR has_super_strength, THEN open the enchanted gate. State VariableA variable that keeps track of the current status or 'state' of t...

The 'AND' Pattern IF (condition1 AND condition2) THEN ... Use this when an action requires multiple things to be true simultaneously. For example, to enter a secret room, you might need a key AND a map. The 'OR' Pattern IF (condition1 OR condition2) THEN ... Use this when an action can be completed in more than one way. For example, to defeat a monster, you could use a magic sword OR a fire spell. The Nested IF Pattern IF (outer_condition) THEN { IF (inner_condition) THEN ... } Use this for sequential checks. The program only checks the inner condition if the outer one is already met. This is great for things like checking if a player is at a door before checking if they have the key. The IF / ELSE IF / ELSE Pattern IF (condition1) THEN ......
