AI in Games!

Smart Computer Opponents

Ever play a game where the computer fights back? Where it seems SMART? That's AI! Today we learn about game AI! 🎮

🤖

Meet NPCs! 👾

Non-Player Characters

NPC = Non-Player Character. These are the characters in games that aren't controlled by YOU. They're controlled by AI! 🤖

Examples of NPCs:

  • 🎯 Enemy soldiers trying to shoot you
  • 🏀 Basketball player defending you
  • ⚔️ Dragon boss fighting you
  • 🏃 Zombies chasing you
  • 🚗 Racing car competing against you
  • 🧙 Wizard casting spells at you

Scratch vs Modern Games! 📚 vs 🎮

Remember Scratch? We programmed everything! Let's compare:

❌ Scratch Way

WE told the sprite EXACTLY what to do:

  • "Move right"
  • "Jump when you hit wall"
  • "Change color"

The sprite does EXACTLY what we programmed. Nothing more, nothing less. 🤖

✅ AI Game Way

AI DECIDES what to do based on what YOU do:

  • "You moved right?"
  • "I'll block you!"
  • "Let me attack!"

The AI THINKS and REACTS to what you do! 🧠✨

The BIG Difference! 💡

Scratch (old way):
"When X happens, do Y"

AI (new way):
"Look at what the PLAYER did, then DECIDE what to do"
🎮🧠

Game AI Examples! 🎮

🏁
Racing Games

Computer cars try to win! They learn your strategy!

⚽
Sports Games

Computer players defend and attack smartly!

🎯
Battle Games

Enemies react to YOUR moves!

🧟
Zombie Games

Zombies hunt you down!

♟️
Chess AI

Computer thinks many moves ahead!

🏠
Simulation Games

Citizens act on their own!

How Game AI Works! 🧠

Let's trace how a game AI makes a decision:

Step 1: AI Sees

👁️ AI looks at the game and sees WHERE YOU ARE

↓

Step 2: AI Thinks

🧠 AI decides what STRATEGY to use

↓

Step 3: AI Chooses Action

🎯 AI picks the BEST move (attack, defend, run, etc.)

↓

Step 4: AI Acts!

⚔️ AI moves, attacks, or does something IN THE GAME

AI Learns From YOU! 📚

The smarter games learn patterns from how YOU play!

AI Remembers:

  • "When I attacked, the player jumped left" 🧠
  • "The player always runs to the right when scared" 🧠
  • "The player likes to hide behind walls" 🧠

So next time, AI uses what it learned!

Example: "Player always jumps left... so I'll attack LEFT this time!" ⚔️✨

Easy vs Hard AI! 🎮

Games have different AI difficulty levels:

😊

Easy AI

Makes dumb mistakes 🤪
Slow reactions ⏸️
Easier to beat ✅

😐

Medium AI

Smart but fair 🧠
Good reactions ⚡
Good challenge! 🎯

😈

Hard AI

Almost impossible 😱
Super fast reactions ⚡⚡
Very hard to beat ❌

Activity: Which Games Have AI? 🎮

Let's identify which games use AI opponents!

Games to Think About:

  • 🎮 Mario Kart — Computer cars race you
  • ⚽ FIFA/Madden — Computer teams play against you
  • 🏹 Fortnite — Enemy players trying to win
  • 🐉 Minecraft — Creepers attack you
  • 🧩 Candy Crush — Just patterns, no AI

Which ones do YOU think have AI? Why? 🤔

Discussion Time! 💬

Let's Talk About Game AI:

  • What game have you played with a smart opponent?
  • Did it feel like playing against a real person?
  • Was the AI easy or hard? Did you win?
  • Can you tell when AI makes a mistake?
  • Would you rather play against AI or real people?

What We Learned! 🌟

  • NPCs = Non-Player Characters (AI-controlled)
  • AI Sees what's happening in the game
  • AI Thinks about the best strategy
  • AI Acts based on its decision
  • AI Learns from how YOU play
  • Different AI Levels — Easy, Medium, Hard
  • AI Makes Games Fun! — Opponents react to you!

Amazing Work! 🎉

You understand game AI!

Next time you play a game with an opponent...
Remember: That computer AI is THINKING and REACTING to what YOU do! 🧠🎮
