2. Game Design Principles: Core Mechanics, Gameplay Loops, and Level Design
Learn about game design principles, including core mechanics, gameplay loops, and level design.
What you'll learn
- Identify and classify at least three distinct core mechanics in popular video games, providing a rationale for their classification based on the mechanic's fundamental role in the game's functionality.
- Diagram and explain the gameplay loop of a chosen video game, including the player actions, system responses, and feedback mechanisms, demonstrating an understanding of its iterative nature and impact on player engagement.
- Apply principles of effective level design (e.g., pacing, flow, visual cues) to create a sketch or digital mockup of a game level, justifying the design choices in terms of their impact on player experience and achievement of specific gameplay goals.
- Evaluate the effectiveness of level design in two different video games, using specific examples to support claims about how level design choices contribute to or detract from the overall gameplay experience and player immersion.

Introduction & Learning Objectives
Learning Objectives
Define a core mechanic and give an example from a game they know.
Identify the three parts of a gameplay loop: action, reward, and new challenge.
Explain that the goal of level design is to create a fun and challenging path for the player.

Describe how a variable can be used to keep track of a player's score or lives.
Create a simple rule for a game, like 'collect 3 coins to win'.
Ever wondered what makes your favorite video game so much fun to play over and over again? 🎮 Let's learn the secret recipe!
We are going to become game designers! In this lesson, we'll learn about the secret ingredients that make games fun: core mechanics (the main actions...

Key Concepts & Vocabulary
TermDefinitionExample
Core MechanicThe main action that the player does over and over in a game.In the game Super Mario Bros., the core mechanic is jumping.
Gameplay LoopA repeating cycle of activities that keeps the player engaged.In Pac-Man, you eat dots (Action), get points (Reward), and then have to avoid faster ghosts (New Challenge). This cycle repeats.
Level DesignThe art of creating the environment, challenges, and path that a player follows in a game.Placing platforms, coins, and enemies in a specific order to make a level fun and not too hard.
ObjectiveThe main goal the player is trying to achieve in a game or level.The objective might be to 'get to the finish line' or 'collect all the stars'.
RewardSomething positive the player receives for completing a task...

Core Syntax & Patterns
The Gameplay Loop Pattern
Action -> Reward -> New Challenge
Use this pattern to make your game fun and addictive. The player does an action, gets a nice reward for it, and then faces a slightly harder challenge that makes them want to perform the action again.
The Level Design Flow
Start -> Easy Challenge -> Harder Challenge -> Goal
When you build a level, guide the player. Give them a clear start, an easy first task to teach them, a harder task to test them, and finally the goal to complete the level.
The Score-Keeping Algorithm
score = score + points
To keep score, create a variable called 'score'. When the player does something good, like grabbing a coin, add points to the score variable to update it.

Challenging
You are designing a stealth game where the core mechanic is 'becoming invisible for 3 seconds.' Which of these would be the most effective gameplay loop?
A.Become invisible, run to the end, win
B.See a guard, become invisible, sneak past the guard, become visible again and wait for the power to recharge
C.See a guard, fight the guard, take the guard's key
D.Run around in circles until the timer runs out
Challenging
A new game has an amazing core mechanic (like building portals) and beautiful art, but players say it's 'boring' and 'pointless.' What is the MOST LIKELY problem a game designer should investigate?
A.The main character's name is not exciting enough
B.The game's icon on the screen is too small
C.The gameplay loop does not use the core mechanic in an interesting or rewarding way
D.The sound effect for jumping is not loud enough
Challenging
A designer wants to make a level feel scary. Which combination of level design and mechanics would be MOST effective?
A.Brightly lit, wide-open spaces with a fast-running character
B.level with happy music and lots of friendly characters to talk to
C.powerful weapon that can defeat any enemy in one hit
D.Narrow hallways, limited light, and a core mechanic where the player has no way to fight back, only hide
