A game engine typically includes several core components that work together to facilitate game development and execution. These components are:
Rendering Engine: Responsible for rendering graphics, including 2D and 3D visuals. It handles lighting, shading, textures, and camera perspectives.
Example: A game engine uses the rendering engine to display a 3D character model with realistic lighting and textures in a virtual environment.
Physics Engine: Simulates physical interactions, such as gravity, collisions, and object dynamics.
Example: In a racing game, the physics engine calculates how a car moves, collides with other vehicles, and responds to terrain changes.
Audio Engine: Manages sound effects, music, and voiceovers, including spatial audio and real-time audio processing.
Example: An audio engine plays footsteps that change based on the surface type (e.g., wood, grass) and distance from the player.
Scripting or Programming Interface: Allows developers to write custom logic, behaviors, and interactions for the game.
Example: A developer uses a scripting interface to create a quest system where NPCs (non-player characters) give tasks to the player.
Input Handling: Processes user inputs from keyboards, mice, controllers, or touchscreens.
Example: The input handler detects when a player presses a key to jump in a platformer game.
Networking Module: Enables multiplayer functionality, including real-time communication and synchronization between players.
Example: In an online shooter game, the networking module ensures that all players see the same actions, such as shooting or moving, in real time.
Resource Management: Handles loading, storing, and optimizing game assets like textures, models, and audio files.
Example: The resource manager loads high-resolution textures only when needed to save memory and improve performance.
Scene Management: Organizes and switches between different game levels or scenes.
Example: A scene manager transitions the player from a city environment to a dungeon when a quest is completed.
AI System: Implements artificial intelligence for non-player characters, including pathfinding, decision-making, and behavior trees.
Example: An AI system makes enemies in a shooter game patrol areas and attack the player when detected.
Cross-Platform Support: Ensures the game can run on multiple devices and operating systems, such as PC, consoles, and mobile.
Example: A game engine with cross-platform support allows a developer to deploy the same game on both Windows and iOS devices.
