Game engines and LWJGL questions

A question regarding 3D, in order to create a FPS, do you have to use a 3D engine or is it possible to create it using a library? What exactly is a Game Engine?

When you "code" for a game engine, what is it doing with your code? When you code using a library, are you "creating" your own game engine? Can you use LWJGL to create a full FPS?

do you have to use a 3D engine or is it possible to create it using a library?

I'm not sure I get what you mean. Though basically when creating a 3D application, you would usually either use OpenGL or DirectX both of them is an API for 2D & 3D rendering. Those aren't 3D engines, but simply the tools for rendering 3D (and 2D). So now you can use one of those and create a 3D engine.

What exactly is a Game Engine?

Basically a Game Engine is a piece of software which runs and controls everything within a game. Most game engines are written in C and C++, though you can of course use any language you want.

When you "code" for a game engine, what is it doing with your code?

When you want to program a game engine, then you basically can do two things.

  1. Create a full game engine which can do basically all the things you would need. Like loading 3D models, perform lighting, etc.
  2. Create a game engine based on a game idea. What I mean by that is, when you have the main game idea, then you can create a game engine for that specific game. Thereby if the game doesn't need any lighting, then you of course don't have to write all the code for performing lighting.

When you code using a library, are you "creating" your own game engine?

Well you don't need to use any extra libraries to create a game engine. The game engine is simply what makes your/the game run. Though you would of course use some sort of graphics rendering API like OpenGL, DirectX, etc. But basically you don't have to.

Can you use LWJGL to create a full FPS?

LWJGL like JOGL is simply a Java OpenGL Wrapper, and using OpenGL you can create any kind of 3D application you want. If you have the skills you could probably create something like Crysis, though I might chose to use C++ or C, instead of Java for creating something huge and advanced as Crysis, though it is possible.

So yes using LWJGL you could easily create any kind of 3D and/or 2D game you want to.
