Introduction & Learning Objectives
Learning Objectives
Identify the key parts of a game character, like their look and abilities.
Define a character's attributes using simple data (e.g., speed = 10, color = 'blue').
Explain how an 'event' (like a key press) can make a character act.
Create a simple 'If...Then...' rule (a conditional) for a character's special power.
Design a unique game hero on paper by listing their attributes and rules.
Describe how changing an attribute (data) can change how the character plays.
If you could create your very own video game hero, what would they look like and what would be their super-special power? 🦸♂️🚀
Today, we are going to be game designers! We will learn how to invent our own game characters by choosing their looks, setting t...

Core Syntax & Patterns
The Event-Action Rule
WHEN [Event] happens, DO [Action]
Use this to make your character do something when the player acts. This is how you make characters controllable.
The If-Then Power-Up Rule
IF [Condition is true], THEN [Do a special action]
Use this to give your character special powers or reactions. The action only happens if the condition is met.
The Attribute Setter Rule
SET [Attribute] TO [Value]
Use this at the start of the game to decide your character's starting information, like their health, speed, or score.

Challenging
You're designing a hero for a puzzle game where the hero must move blocks onto switches. Which character design is the most effective and creative?
A.super-strong hero who can smash blocks instead of moving them.
B.hero with a 'push' ability and a special 'tractor beam' to pull blocks from a distance.
C.super-fast hero who can run around the blocks very quickly.
D.hero who can fly high above the blocks and switches.
Challenging
A hero can be either 'Fast but Weak' or 'Slow but Strong'. What is the main reason a designer would make a player choose between these two options?
A.To force the player to find a secret third option that is both fast and strong.
B.To make the game unfair for players who choose the 'wrong' hero.
C.Because it is easier to code a hero with a weakness.
D.To create a meaningful choice where the player trades one advantage for another, suiting different playstyles.
Challenging
Design a conditional rule for a 'water hero' who gets stronger in rain and weaker in the desert. The hero has a 'power_level' data value.
A.IF the hero is near a cactus, THEN power_level increases.
B.IF the game weather is 'rain', THEN power_level doubles; ELSE IF the level is 'desert', THEN power_level is cut in half.
C.IF the hero jumps, THEN the weather changes to rain.
D.The hero's power_level is always 100, no matter what.
