Vector
In math, a vector is a list of numbers representing a direction and a length (called the vector's magnitude).
In math, vectors can be lists of numbers of any length, though in games, we mostly use vectors to represent 2D and 3D coordinates. So, we mainly use vectors with 2 and 3 numbers.
A 2D vector has two values representing the x and y coordinates, while a 3D vector has three values for the x, y, and z coordinates.
In Godot, vectors are essential for representing positions, velocities, and forces within a game world. We use them in scripts to control characters, detect collisions, and more. Godot provides two primary vector types: Vector2 for 2D, and Vector3 for 3D.
Common vector operations
You can manipulate vectors with various operations, including:
- Addition and subtraction: You can use these to move a sprite or a character in the game world.
- Multiplication and division: You can scale vectors by multiplying or dividing them by a number.
