1. Remix the Maze Starter Project

Hey and welcome to day three of Scratch Games.

Today you're going to explore If statements, while creating a Maze Game.

If statements allow the computer to check a condition; decide whether to do something.

If statements have two parts, an If and a Then.

They can be read, 'If this is true, Then do this'.

Take a look at the game Pac-Man as an example.

Pac-Man is a classic arcade game from the 1980s.

In this game, a Pac-Man character must avoid a swarm of enemies.

The Pac-Man character uses If statements in many different ways.

For example, if Pac-Man is touching an enemy, then he looses a life.

In Scratch, you can express the same kind of statement with a Block-Stack.

For example, you could code an If statement that directs the computer if touching enemy, then change lives by minus one.

Even the maze in Pac-Man uses If statements.

Pac-Man can only move forward if he is not facing a wall.

Today, you'll create a game where players guide a Sprite through a maze using the mouse.

You'll use If statements multiple times.

For example, if the sprite touches the walls of the maze, then it changes directions or if the sprite touches a bug at the end of the maze, then the game ends.

Check out the different Starter Projects and decide which one fits the story your game will tell.
