for _creep in Game.creeps:
    do_something ( _creep )

is translated to JS like this:

for (var _creep of Game.creeps) {
    do_something ( _creep );
}

which raises an error on screeps game console :

TypeError: Game.creeps is not iterable

Changing "_creep of Game.creeps " to "_creep in Game.creeps" fixes the error.

Dunno how

- None of the constructors for game objects are accurate. It's not reliable to create these in game, but a 'fake' constructor with all attributes as arguments is created to give type checkers correct thoughts on what properties should exist.

Adding assert False, 'with some message' or raise NotImplementedError('with some message') to constructors would prevent people from misusing them.

How to fix it?

I am using python 3.6 and always get this error

Link to the Enviroment setup doesn't work in the readme, so does the others link don't work anymore.
Also is this repo still working with the current screeps version?

Async has become a keyword with python 3.7, which breaks Transcrypt

im not sure if this issue is new or similar to the bin removed error previously posted if its the same thing ill just post a comment in the other issues post. This is also my first issues post so if i leave anything out please comment and ill edit the post. here is what my terminal spits out when i tried to python3 build.py. python3 isnt new on my system but node is, so perhaps thats the issue? anyway heres the terminal results:

Thanks in advanced.

Screeps claims to be python-compatible, but the only version of python you can play it is so old it's illegal to code in it. There is a new version of transspiler that supports python 3.9 already, but this repository is not using it. As far as I see, there is not even a ton of changes, it's like 66 commits and 17 merges (the dabross performance patches would need to be potentially updated). Lots of modern python syntax could be enabled, python is on the hype wave, it would be cool to be able to use it with python properly.

Got the program working but it uses syntax from ES6 which is not supported in screeps such as import/export

Hi -

This is really trivial so I'll probably close it myself.

When I click on this:

It says I need to log in to preview content, but I can't sign up.

In python:

>>> q=[1,2,3]
>>> y=[4,5]
>>> z=q+4*y
>>> z
[1, 2, 3, 4, 5, 4, 5, 4, 5, 4, 5]

Above translated via transcrypt:

var q = list ([1, 2, 3]);
var y = list ([4, 5]);
var z = q + 4 * y;
console.log (z);
1,2,3NaN

So array manipulation doesn't translate right

this same problem in python 3.12 and in conda python 3.11

The config.default.json seems to only consider the official screeps server.

Is it possible to configure the screeps-starter-python for private server as with screeps-typescript-starter ?

I guess it's because Transcrypt tries to translate

if TYPE_CHECKING:
    from transcrypt.modules.org.transcrypt.stubs.browser import __pragma__

So I would just do

# __pragma__('skip')
from transcrypt.modules.org.transcrypt.stubs.browser import __pragma__

PS I hope to make a PR a bit later :)

When attempting to build it with a fresh install of node.js, the build fails because it attempts to call "npm bin" but that command had been removed in npm 9.0.0. They say to use "npm exec" instead but I'm not sure how I'd have to modify the syntax to work with the different command.

To be consistent with the config.default.json file, where the password entry isnt present,

In build.py, l73

Change
self.password = config_json['password']

To
self.password = config_json.get('password')

how to fix it?

Who doesn't love an excessively detailed README? Can you really resist the urge to put in a sweet table of continents?

The README by itself isn't lacking in respect to what it does or what it tries to accomplish. Unfortunately, because of how Screeps handles certain methods and objects, finding a python syntax that fits can be confusing at first. This isn't anyone's fault, it's just the nature of writing Python code that will be translated to equivalent JavaScript for a specific program.

The idea for this came from doing the tutorials where it was initially hard to find a way to write some expressions in Python that would accomplish what the tutorial was asking me to do (like passing a filter expression as an optional argument). The slack channel was immensely helpful helpful though, and after asking a few questions, it was immediately clear there is usually a way to create similar Python code. However, because the message history for the #Python channel goes back only a few days, there is no record of the questions asked (or the answers).

To help those new to Screeps who want to write their code in Python, I think a mini-guide of sorts containing Python equivalent code of common Screeps idioms and code usage. It wouldn't cover every conceivable case, just how to accomplish some of the more complex features Screeps offers using Python syntax.

I'd like to start working on a rough draft for this idea, but wanted to get feedback before I put anything together to see if it would be fitting for the project itself.
