以下是使用虚幻引擎5编写飞机大战游戏代码示例： ```cpp // 导入所需头文件 #include "Engine/Core/Engine.h" #include "Engine/World/World.h" #include "Engine/Rendering/Canvas.h" #include "Engine/GameObjects/Character/Character.h" #include "Engine/GameObjects/Projectile/Projectile.h" #include "Engine/GameObjects/Player/Player.h" #include "Engine/GameObjects/Enemy/Enemy.h" #include "Engine/GameObjects/Environment/Environment.h" #include "Engine/GameObjects/Camera/Camera.h" #include "Engine/GameObjects/UI/UI.h" #include "Engine/GameObjects/UI/UIElements/UIText.h" #include "Engine/GameObjects/UI/UIElements/UIButton.h" #include "Engine/GameObjects/UI/UIElements/UISlider.h" #include "Engine/GameObjects/UI/UIElements/UILabel.h" #include "Engine/GameObjects/UI/UIElements/UIInputField.h" #include "Engine/GameObjects/UI/UIElements/UIImageView.h" #include "Engine/GameObjects/UI/UIElements/UISprite.h" #include "Engine/GameObjects/UI/UIElements/UIRectangle.h" #include "Engine/GameObjects/UI/UIElements/UILine.h" #include "Engine/GameObjects/UI/UIElements/UIBox.h" #include "Engine/GameObjects/UI/UIElements/UIPanel.h" #include "Engine/GameObjects/UI/UIElements/UIGroup.h" #include "Engine/GameObjects/UI/UIElements/UIList.h" #include "Engine/GameObjects/UI/UIElements/UITableView.h" #include "Engine/GameObjects/UI/UIElements/UITableViewRow.h" #include "Engine/GameObjects/UI/UIElements/UITableViewCell.h" #include "Engine/GameObjects/UI/UIElements/UISpriteSheet.h" #include "Engine/GameObjects/UI/UIElements/UITextureAtlas.h" #include "Engine/GameObjects/UI/UIElements/UIFont.h" #include "Engine/GameObjects/UI/UIElements/UIColor.h" #include "Engine/GameObjects/UI/UIElements/UISpriteBatcher.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRenderer.h" #include "Engine/GameObjects/UI/UIElements/UISpriteFrameCache.h" #include "Engine/GameObjects/UI/UIElements/UISpriteBatcherRenderer.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_1.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_2.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_3.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_4.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_5.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_6.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_7.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_8.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_9.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_10.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_11.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_12.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_13.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_14.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_15.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_16.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_17.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_18.h" #include "Engine/GameObjects/UI/UIElements/UISpriteRendererFactory_Cpp_19.h" #include "Engine/GameObjects/UI/UIElements// Engine::USceneComponent* pScene = GetActive()->GetRoot().FindChild("MyScene"); ``` 在上述代码中，我们创建了一个空的`Actor`对象，并设置了其位置、缩放比例等属性。然后，我们调用了`Update`方法来更新游戏状态，并调用了`Render`方法来渲染游戏画面。我们还使用了`HandleInput`方法来处理用户输入，以及`StartCoroutine`和`EndCoroutine`方法来启动和结束游戏循环。
