Part 3 - If Statements

---

Summary

If statements are a type of conditional logic. They check whether a condition is true and run one block of code if it is, and another block if it is not.

---

Syntax

if (condition)
{
    // Run this code
}
else
{
    // Run this code instead
}

---

Example

if (Input.GetAxisRaw("Horizontal") != 0)
{
    MovePlayer();
}
else
{
    return;
}

This checks for keyboard input. If the player presses A, D, Left Arrow, or Right Arrow, the player moves. Otherwise, the script returns without moving the player.

• I can explain what an if statement does.
• I can read basic if/else logic in a script.
