Question: Does Godot use Python?

Answer

No, Godot does not use Python as its primary scripting language; instead, it uses a Python-like language called GDScript. GDScript is designed to integrate seamlessly with the Godot editor and is tailored specifically for the high-level node-based architecture of Godot.

Here's an example of how GDScript code looks:

extends Sprite

# Member variable
var speed = 100

# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(delta):
    var input_vector = Vector2(0, 0)
    input_vector.x = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left")
    input_vector.y = Input.get_action_strength("ui_down") - Input.get_action_strength("ui_up")
    input_vector.normalized()

    position += input_vector * speed * delta

This example shows a _process function that moves a sprite based on user input. The syntax should be familiar if you are used to Python but GDScript is a separate language with its own quirks.

However, there is also an option to script in other languages through plugins or modules. For example, there is a plugin called "GodotPython" which enables scripting in Python. These are community-driven projects and are not officially maintained by the Godot Engine developers. Here is an example of how this might look if you were to write a script using the Python plugin:

from godot import exposed, export
from godot.bindings import *

@exposed
class Player(Node2D):

    @export
    var speed = 100

    def _process(self, delta):
        input_vector = Vector2.ZERO

        if Input.is_action_pressed('ui_right'):
            input_vector.x += 1
        if Input.is_action_pressed('ui_left'):
            input_vector.x -= 1
        if Input.is_action_pressed('ui_down'):
            input_vector.y += 1
        if Input.is_action_pressed('ui_up'):
            input_vector.y -= 1

        input_vector = input_vector.normalized()
        self.position += input_vector * self.speed * delta

Regardless, the official and most optimized way to script in Godot is by using GDScript.
