      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.

      ​@@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.

    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.

      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

    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 :)

    BRO, did u go the game school or something? Where did u learn the physics? I knew those math equations but didn't knew they can be applied like that. It was really cool how a single equation define a whole behaviour. 😍
