Array¶
A built-in data structure that holds a sequence of elements.
Description¶
An array data structure that can contain a sequence of elements of any type. Elements are accessed by a numerical index starting at 0. Negative indices are used to count from the back (-1 is the last element, -2 is the second to last, etc.).
Example:
var array = ["One", 2, 3, "Four"]
print(array[0]) # One.
print(array[2]) # 3.
print(array[-1]) # Four.
array[2] = "Three"
print(array[-2]) # Three.
var array = new Godot.Collections.Array{"One", 2, 3, "Four"};
GD.Print(array[0]); // One.
GD.Print(array[2]); // 3.
GD.Print(array[array.Count - 1]); // Four.
array[2] = "Three";
GD.Print(array[array.Count - 2]); // Three.
Arrays can be concatenated using the + operator:
var array1 = ["One", 2]
var array2 = [3, "Four"]
print(array1 + array2) # ["One", 2, 3, "Four"]
// Array concatenation is not possible with C# arrays, but is with Godot.Collections.Array.
var array1 = new Godot.Collections.Array{"One", 2};
var array2 = new Godot.Collections.Array{3, "Four"};
GD.Print(array1 + array2); // Prints [One, 2, 3, Four]
Note: Arrays are always passed by reference. To get a copy of an array that can be modified independently of the original array, use duplicate.
Note: Erasing elements while iterating over arrays is not supported and will result in unpredictable behavior.
