      To be fair, there's nothing about this that make it really "an engine", the title is just pure clickbait. It's just few of the most common classes that are absolutely necessary to make any kind of 3D game.

      @@dwarfda which is all an engine is? It's just a collection of tools and classes that are necessary to make a game, he wasn't going to implement a complex physics engine, audio, animation, etc. all within 48 hrs. But what he built was still an engine...

      ​@@dwarfdaif you consider it to be on the level of Unity and whatnot, sure it isn't "a game engine" but that is also a bit short sighted. An application is an application regardless of how it holds up. That scrutiny only matters when you're trying to ship a product.
      It is still a game engine but is it a versatile or well documented and modern game engine? No not really yet it isn't trying to be for now.

    1. create a hello world program and make sure it compiles
    2. build your engine

    Writing your own game engine is impressive, but as a game dev, I find the completeness of the game for jam even more important. Therefore, these two aspects together makes your work amazing. Maybe it is not perfect in terms of game design, but it's very cool anyway!

      I still give him credit for coming up with a complete loop with a theme-appropriate mechanic given the tools he has to work with. Sometimes it's an interesting exercise to think of the simplest possible thing that's mechanically fun or interesting. It could build good practices to prevent feature creep too.

    Very nice work for 48 hours... I would of just coded a very simple platformer engine, but I'm pretty simple.
    I think my favourite part was the collision detection/physics. I've found 3D collision to be quite the pain to debug, so I really like how you simplified it to what you specifically needed for the project. Very neat :D

    Impressive work 👏! A gameplay loop could be that you get a higher score the longer path the ball rolls before it land in the hole. So you could play it safe by putting the hole closer to the starting point, or try to get a high score by placing the hole far from the starting point.

    Game engines like Unity and Godot etc are great but often times you will be struggling to get what you have in mind implemented. They are not magic bullets. Sometimes they can actually get in the way. I highly recommend anyone with a serious interest in game dev try making a few games using only OpenGL. Its harder yeah but i don't think its as hard as most people that have nt done it think. I love and use game engines as well but ive always got a hand in a opegl only project. Ive written a couple of different model loaders for use in those projects that support pbr materials and skeletal anim for dae and gltf in windows and one for android. Qoite a piece of work but not as hard as i would have initially thought.

    For simple projects I prefer using RayLIB instead of SDL2 or SFML. The graphic window initialization code is much shorter, yet you still can acces openGL directly and use shaders not limted by framework. And still can do all the low-level stuff (engine) since the raylib itself missing many features and definitely not an engine by itself (it has basic 3d model rendering functions and some rudimentary resource loading system, though).
    At least you should check it out :)

      To clarify, I did not use python as a wrapper for C++ functions. I created a 3d model of a terrain in blender, then exported a heightmap png from blender. Then I made a python script that calculates the gradient of this image and outputs the result as another png. Then Portable Par, loads this gradient image on startup and uses it for physics.
      So the python is a script to convert one png to another before loading in the game

    If I wanted to make a engine like the build engine but able to use 3d models like quake or heretic 2. What would be the way to start for a complete newbie? I want to make a retro shooter but without all the bloat that some game engine come with lol

      Assuming you know C++ well, OpenGL is the best graphics api (to learn graphics programming) in my opinion, it's a bit old now so Vulkan is better but Vulkan should be learned after understanding opengl.

    Why not just make a file reader that can read the obj files rather then include and external library?
    Obj files themselves are not complicated to get data from in the first place.

      I keep thinking about this lol. It might even have been faster to code haha

    How many years experience do you have with C++ and OpenGL?

      For opengl, I basically just took an undergraduate course in computer graphics + a couple minor projects. In that course, we did everything you saw in this video, so I was already familiar. For the C++, checkout my other video
