supertux VS julius

SuperTux - Platformer inspired by Mario Brothers. C++, SDL2

Looking at the repo for SuperTux as featured here in https://news.ycombinator.com/item?id=39528726 and trying to understand how the cross platform aspect works. Am I correct in my thoughts that it's OpenGL based, using a cross platform library called Simple DirectMedia Layer aka SDL, found at https://www.libsdl.org?

I see a frequently occurring header file called SDL.h, but when I search the repo at https://github.com/SuperTux/supertux I can't find it.

What is SDL.h and why am I unable to locate it?

Well, there actually is/was a Supertux 2. I don't remember the specifics, I think they rewrote it from blit 2D into OpenGL? You can see here : https://github.com/SuperTux/supertux/blob/master/supertux2.d... that it's called supertux2

But yeah this has nothing to do with the actual content of the levels, it only refers to the engine.

nix run git+https://github.com/supertux/supertux.git?submodules=1

If you know the file name, you can use the "Go to file" button to search for files with some specific name -- e.g. https://github.com/SuperTux/supertux/find/master

Some open source games using C++ include SuperTux, SuperTuxKart, OpenRCT2

Julius) - Caesar 3 clone. C, SDL2

Cesar 3 was also rewritten (https://github.com/bvschaik/julius), and besides the marvelous work from the author that has allowed fans of the original to experience it on modern platforms and further preserve it, it has also invigorated the community and spawned other efforts to further enhance the game.

It’s a shame that many companies do not agree with such an approach for dormant or abandonware properties.

Picked it up on GoG a while back and had a great time with it. Keep thinking about it every so often despite not finding the time to play through it again. Last year I decided to teach myself a specific game engine by replicating the game. I am not a game developer so I was in over my head and I stopped but I revisited the project earlier this month and managed to get basic map rendering working with the original tiles. The julius project together with citybuilding-tools and ZeusMapper were a great help to learn how to read the original asset files. I see all the Caesar 3 maps on this subreddit and would love to at least be able to generate those for Zeus + Poseidon one day even if I never get any actual game logic working. However just trying to figure out the logic for how cliff and rock formations are rendered is enough to make me think that will never happen. What I wouldn't give for a peek at the original source code.

Caesar III was recently reverse engineered, and is now receiving updates (project Julius on github) and new features (project Augustus on github).

There is Julius if you want to play it today https://github.com/bvschaik/julius

I just got my Steam Deck and one of the first things I'd like to try is to play the old city-building Caesar III. I searched a bit and it seems that the only way to run it is through https://github.com/bvschaik/julius/releases/tag/v1.7.0 installation. Can you please explain how to do it?

An old city builder called Caesar 3 has a Steam release, and an open source implementation named Julius that works natively on linux.

there is an open source copy of this game called Julius that fixes some aspect ratio issues of this game and is free to download (you need to have bought a legal copy of the game for it to work though). they also made a version called Augustus that adds a bunch of new things, like the monument system from later games ins the series. https://github.com/bvschaik/julius
