Usage about godot-nim HOT 19 CLOSED

The fork is not required anymore, you can use godot's official master branch: https://github.com/godotengine/godot

If by "prebuilt godot" you refer to 3.0-alpha1, then no, it cannot be used, because it was built earlier than the PRs were merged. But the next alpha/beta release will work.

@endragor to be more specific, what is the entry point? I compiled and run apigen.nim, which successfully created a bunch of nim files as I would expect. I tried compiling nimruntime.nim and godot.nim, but start to get errors later on down the pipeline. In general I can't figure out how to generate the .so library file I believe I need to point godot to in order to use the nim bindings.

Hmm, this got attention faster than I expected :) Thank you for your interest, @rosshadden. I'll add sample project soon enough (hopefully today) - there are still several fixes that need to be applied to Godot for this to fully work.

from godot-nim.

I added simple project as a setup example: https://github.com/pragmagic/godot-nim/tree/master/examples/simple
It shows how to load/instantiate scenes, handle input, perform actions on game tick. Hopefully this can serve as a starting point. The rest actually comes from Godot API knowledge which you can get from either going through the generated files (in godotapi folder) or official documentation.

I haven't tested it on Linux so if it doesn't work there (could be because of wrong paths in build script, for example), then please let me know or make a PR that fixes it.

Awesome, thanks!

By the way, the reason I found this so quickly is that had have been planning to do this for a couple months (I figured I would have to, since Nim isn't as popular as it deserves yet), and coincidentally just sat down this week to start seeing what was necessary by looking at existing bindings for other languages. Part of that research involved searching GitHub for "Godot bindings", which surprisingly led me to this which you had literally just started 😂.

from godot-nim.

Alright :) It's actually quite complete already, there are few known bugs that are going to be fixed by the end of the week. We are using it to develop an actual commercial game (actually, in the process of migrating an existing unpublished game from UE4).

I got it all working. Thanks for your help, and for making the project. Sorry for the noise---I had made some comments while trying to figure something out, and have since deleted them.

nake build is supposed to create .so. There is no way the example can work without it :)
And regarding the symlink - yeah, there was one step missing in the instructions. It is to install the library in advance, so that nakefile can access apigen: nimble install https://github.com/pragmagic/godot-nim.git. Will add that.

from godot-nim.

Yay, much thanks for these bindings!!!!!
Nim is a perfect fit for Godot!
Much thanks again!

@endragor can you please give links to the PR's that are required to use default godot branch?

Only godotengine/godot#9721 is left and we discussed a different approach with @karroffel. I'll implement it today and release v0.3.0, there is a bunch of changes incoming. I'll add documentation when everything works as expected.

from godot-nim.

@endragor ok, thanks!

from godot-nim.

@endragor so we can use prebuilt godot now?

from godot-nim.

@endragor I have an issue compiling godot-nim on Windows:
Invalid GODOT_BIN path: "E:\godot\bin\godot.windows.opt.tools.32.exe"

from godot-nim.

Ah, it seems that it doesn't like quotes in path to bin

from godot-nim.

@endragor Sorry, I've never used Godot and godot-nim, yet. Does godot-nim use GDNAtive for communication with Godot?

from godot-nim.

Yeah man, GDNative, or whatever they are calling it these days.

from godot-nim.

@rosshadden sorry for another stupid question: can game with nim be ported to mobile platforms?

from godot-nim.

Maybe I don't understand your question, but the languages you use to program a game---whether they are built-in or through gdnative---have nothing to do with Godot's export capabilities.
