What Are Conditions?

In Unit 2, your game learned how to store and update information: health, coins, XP, and more. In Unit 3, your game learns how to think about that information and make decisions.

This is where conditions come in.

1. What is a condition?

A condition is a question your program asks about the data it has.

• Is the player’s health below 20?
• Does the player have enough coins?
• Has the player reached level 5?

Each condition can only be answered in two ways:

• True
• False

If the condition is True, the game does something.

If it is False, the game does something else—or nothing at all.

2. The if Statement

if condition:
    # code that runs when the condition is True

This is how your game starts making decisions.

3. Example: Low Health Warning

health = 15

if health < 20:
    print("Warning: Health is low!")

• The condition is health < 20.
• If health is less than 20, the message is printed.
• If health is 50, nothing happens.

This is the beginning of game logic: your game reacts to the player’s situation.

4. Example: Enter the Cave

torch = True

if torch == True:
    print("You enter the dark cave.")

Here, the game checks if the player has a torch.
If the condition is True, the player can enter.
