Game Engine

A game engine is a software framework that provides the reusable core systems needed to build a video game, so developers do not write everything from scratch. Typical parts are a renderer, physics simulation, audio, input handling, animation, scripting and tools for assembling scenes.

Why it matters

Choosing an engine shapes a project's platforms, performance, team skills and cost. Engines let small teams ship across PC, consoles and mobile by abstracting graphics APIs and hardware differences. They also affect how games run: how efficiently they use the GPU, how they schedule updates and how they handle networking.

Example

Most engines run a loop like this on every frame:

while (running) {
  readInput();
  updateGameLogic(deltaTime);
  simulatePhysics(deltaTime);
  renderFrame();
}

Using deltaTime, the elapsed time since the last frame, keeps movement speed the same whether the game runs at 30 or 144 FPS.

Common mistakes

• Picking an engine by popularity alone, without checking platform support and licensing terms.
• Tying game logic to frame rate instead of elapsed time.
• Assuming the engine handles multiplayer fairness; authoritative game servers still need design.
