In GDScript there is built-in Array class, that implements either 'push', 'pop', 'top' and 'empty' methods. Method names are:
<ul>
<li>push -> push_back</li>
<li>pop -> pop_back</li>
<li>top -> back</li>
<li>empty -> is_empty</li>
</ul>
<syntaxhighlight lang="gdscript">
extends Node2D
func _ready() -> void:
# Empty stack creation.
var stack : Array = []
# In Godot 4.2.1 nothing happens here.
stack.pop_back()
if stack.is_empty():
print("Stack is empty.")
stack.push_back(3)
stack.push_back("Value")
stack.push_back(1.5e32)
print(stack)
print("Last element is: " + str(stack.back()))
stack.pop_back()
print(stack)
print("Last element is: " + str(stack.back()))
if not stack.is_empty():
print("Stack is not empty.")
return
