Question-10. What is the difference between _process() and _physics_process()?
Answer-10: _process() is for general updates; _physics_process() is for physics-related updates.
Question-11. How do you create a new scene in GDScript?
Answer-11: Instantiate a PackedScene and instance it. Example: var scene = preload("res://path.tscn").instance().
Question-12. What is preload() used for in GDScript?
Answer-12: Loads a resource at compile time.
Question-13. How do you load a resource dynamically?
Answer-13: Use load(). Example: var texture = load("res://path.png").
Question-14. Explain the extends keyword.
Answer-14: Used to inherit from another class. Example: extends Node2D.
Question-15. How do you define a class in GDScript?
Answer-15: Implicit by the file name. Use extends for inheritance.

Question-18. How do you iterate through an array?
Answer-18: Use for. Example: for i in my_array: print(i).
Question-19. What is the difference between load() and preload()?
Answer-19: load() is runtime, preload() is compile time.
Question-20. Explain the usage of match in GDScript.
Answer-20: A pattern-matching control structure. Example: match x: case 1: print("One").
Question-21. What is a singleton (autoload) in Godot?
Answer-21: A globally accessible script or scene. Set via Project Settings > AutoLoad.
Question-22. How do you call a method from another script?
Answer-22: Use get_node() or reference the script directly. Example: get_node("NodePath").method().
Question-23. Explain onready in GDScript.
Answer-23: Delays initialization until the node is ready. Example: onready var sprite = $Sprite.
Question-24. What is a Timer in Godot?
Answer-24: A node that counts time and emits a signal after a set duration.
Question-25. How do you pause a game in GDScript?
Answer-25: Set Engine.time_scale = 0 or pause individual nodes.
Question-26. How do you check if a node exists in the scene tree?
Answer-26: Use has_node("NodePath").
Question-27. What is the use of the $ shorthand in GDScript?
Answer-27: A shortcut for get_node(). Example: $Sprite is equivalent to get_node("Sprite").
Question-28. How do you access the root node of a scene?
Answer-28: Use get_tree().root.
Question-29. What is the yield() function in GDScript?
Answer-29: Suspends execution until a signal or condition is met. Example: yield(timer, "timeout").
Question-30. How do you export variables in GDScript?
Answer-30: Use export. Example: @export var speed = 10.
Question-31. What is the Tool keyword used for?
Answer-31: Enables a script to run in the editor. Example: @tool extends Node2D.
Question-32. How do you debug scripts in Godot?
Answer-32: Use breakpoints, print(), and the debugger panel.
Question-33. What is a Group in Godot?
Answer-33: Logical collections of nodes. Nodes can be added to a group using add_to_group().
Question-34. How do you play an animation in Godot?
Answer-34: Use AnimationPlayer.play("animation_name").
Question-35. How do you create a custom resource in GDScript?
Answer-35: Extend the Resource class. Example: class_name MyResource extends Resource.
Question-36. How do you access a child node in GDScript?
Answer-36: Use get_node("NodePath") or $NodePath.
Question-37. What is a PackedScene?
Answer-37: A saved scene that can be instanced.
Question-38. How do you instance a scene in GDScript?
Answer-38: Use var instance = packed_scene.instance().
Question-39. How do you check for input actions in GDScript?
Answer-39: Use Input.is_action_pressed("action_name").
Question-40. What is the purpose of _init() in GDScript?
Answer-40: It's called when an instance of the script is created.
Question-41. How do you detect collisions in Godot?
Answer-41: Use physics nodes like Area2D or CollisionShape2D and their signals.
Question-42. How do you work with random numbers in GDScript?
Answer-42: Use randi() or randf(). Example: randf() * max_value.
Question-43. What are Enums in GDScript?
Answer-43: A way to define named constants. Example: enum { STATE_IDLE, STATE_MOVE }.
Question-44. How do you use a Viewport in Godot?
Answer-44: Use it to render a specific part of the scene or for offscreen rendering.
Question-45. How do you pause a Timer node?
Answer-45: Use timer.stop() or set timer.paused = true.
Question-46. What is the difference between Node and Node2D?
Answer-46: Node2D is specialized for 2D, while Node is generic.
Question-47. How do you emit a signal in GDScript?
Answer-47: Use emit_signal("signal_name", optional_arguments).
