Is the game engine written in C++?

[Intellect]

Hi all! I have been working in C++ for a while now and was wondering if I could contribute to engine development. I was wondering if the game logic/engine was written in C++, and if so, if there is a way to work to develop a certain mod/style of UI for a game design that I have, or if I could contribute directly to the game development directly!

 

Thanks

Hi,

The engine is in c++, movement manager, pathfinder, ui components, los logic.

Anything related to simulation logic, ui/gui handling is in JavaScript/xml.

Ah, I see. Have any recent mods been made that make deep changes to the c++ state of the game? I'd be interested in poking around in those!

I don't think there are any mods changing cpp. They would need to recompile and distribute their binaries for all platforms. making essentially own standalone version of the game.

Also what exactly do you want to do.

For changing ui you do not need to change cpp, xml and js is enough, unless you need some functionality that does not exist yet.

Are you familiar with the Age of Empires online Celeste Project? Basically, I'd like to change the game function so that it no longer requires "territory" space to build. This is a major hindrance to aggressive gameplay because buildings cannot be built forward outside of territorial spaces. However, there are a few game elements that would need to be changed as well.

There is component in templates (xml) of structures where they can be build.

I suggest to go through components and check what each of them do so you get overview  https://github.com/0ad/0ad/tree/master/binaries/data/mods/public/simulation/components

Any structure or unit in game is defined by its template.

https://github.com/0ad/0ad/tree/master/binaries/data/mods/public/simulation/templates

E.g. for your change you need to edit the building restrictions https://github.com/0ad/0ad/blob/b0214ff96935f45e2ff46d8127e2ed38639a013e/binaries/data/mods/public/simulation/templates/template_structure.xml#L6

there is a (js) mod by @wowgetoffyourcellphone that does that already. don't know if it's updated to this alpha though.

anyway, c++ programmers are in high demand, if you stay you'll find out you could easily make yourself very useful the moment you wanted to. for instance there is much room for optimiziation.

Could use a review on https://code.wildfiregames.com/D1581 to toggle the visibility in C++

What is Rust used for? (noticing that in the build instructions).

thanks!
