C# (Unity)

Easiest to learn, most used for game dev

csharp

// ✅ Production-Ready: Unity MonoBehaviour Template
public class GameEntity : MonoBehaviour
{
    [SerializeField] private float _speed = 5f;
    [SerializeField] private int _health = 100;

    public event Action<int> OnHealthChanged;
    public event Action OnDeath;

    private Rigidbody _rb;
    private bool _isInitialized;

    private void Awake()
    {
        _rb = GetComponent<Rigidbody>();
        _isInitialized = true;
    }

    public void TakeDamage(int amount)
    {
        if (!_isInitialized) return;

        _health = Mathf.Max(0, _health - amount);
        OnHealthChanged?.Invoke(_health);

        if (_health <= 0)
            OnDeath?.Invoke();
    }
}

Key Features:

Object-oriented, managed memory
LINQ for data queries
Coroutines for async game logic
Events and delegates
Garbage collection (requires optimization)

Learning Path: 2-3 weeks basics, 2-3 months mastery

最容易学习，游戏开发领域使用率最高

C++ (Unreal Engine)

Most powerful, steepest learning curve

cpp

// ✅ Production-Ready: Unreal Actor Template
UCLASS()
class MYGAME_API AGameEntity : public AActor
{
    GENERATED_BODY()

public:
    AGameEntity();

    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Stats")
    float Speed = 500.0f;

    UPROPERTY(ReplicatedUsing = OnRep_Health)
    int32 Health = 100;

    UFUNCTION(BlueprintCallable, Category = "Combat")
    void TakeDamage(int32 Amount);

    DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnHealthChanged, int32, NewHealth);
    UPROPERTY(BlueprintAssignable)
    FOnHealthChanged OnHealthChanged;

undefined

类Python语法，语法最简单

gdscript

undefined

✅ Production-Ready: Godot Node Template

extends CharacterBody2D class_name GameEntity

signal health_changed(new_health: int) signal died

@export var speed: float = 200.0 @export var max_health: int = 100

var _health: int = max_health

func _ready() -> void: _health = max_health

func take_damage(amount: int) -> void: _health = max(0, _health - amount) health_changed.emit(_health)

if _health <= 0:
    died.emit()
    queue_free()

func _physics_process(delta: float) -> void: var direction = Input.get_vector("left", "right", "up", "down") velocity = direction * speed move_and_slide()


**Key Features:**
- Dynamic typing with optional type hints
- Simple, Python-like syntax
- Signals for messaging
- First-class functions
- Growing ecosystem
