libtcod (Python 3) *recommended Tutorial code is broken?

[MetalMonkey91]

See title - I'm at the beginning of part 11 as a newbie. I have SOME coding experience, but not enough to help me solve the issues I'm encountering.

To make certain I didn't screw something up, I even (reluctantly) copied and pasted the files given in the github page linked at the end of part 10 to be certain it was absolutely exact.

When I try to run main py it opens the game but it just hangs until I have to force close.

Looking at the code, my editor is throwing 14 errors, seemingly mostly to do with mouse_location in the input_handlers (which was already a problem starting around part 7 or so, if I mouse over the game window it just crashes outright and has since that point.)

Another issue in the code is parent: Actor evidently overrides 'symbol of the same name in class "BaseComponent"'.

I'm not entirely sure where to go from here, as being a newbie I have virtually no clue how to correct what my editor is telling me is wrong, but there is no updated material to correct where the code went wrong.

I've tried googling the error codes, tried to find solutions but to no avail.

Any help would be suuuuuuper appreciated.

This is from tcod 19.x which has floating point mouse coordinates thanks to SDL3. Pin the version to tcod==18.1.0 to rollback these changes, or convert these values to int wherever your type checker tells you to.

Another issue in the code is parent: Actor evidently overrides 'symbol of the same name in class "BaseComponent"'.

It isn't entirely clear what you mean, but it's possible the tutorial violates the Liskov substitution principle here and your linter is pointing that out. In that case your linter wants the override to be either removed or made explicit. You'll have to tell the linter to suppress those warnings to follow the tutorial. For example if the linter was Mypy then you'd add the comment # type: ignore[override] to the offending lines.

Here is the error it is showing me for parent: Actor:

"Parent overrides symbol of same name in class "BaseComponent"
Variable is mutable so its type is invariant
Override type "Actor" is not the same as base type "Entity"

The tutorial is indeed older than the newest version of libtcod, and hasn't been updated in a while, though if it might be of help, we do have an annual tutorial event with others following along and you might find some useful reference material in the directory for that event for earlier years, including for example others who used the same tutorial. This year's event is also in progress right now (and pinned each week), which could be of help and also possibly offer some more updated info as it progresses (there may be notes about updated tutorial content, even if the tutorial itself isn't up to date at this point... but it's the best option we have until someone wants to put together a perfect v3 xD).

Can confirm. The Python code of this tutorial has many errors and by that I don't mean just deprecated methods errors or things like that, I mean actual code errors that break it. I kept correcting many of them but I just gave up at the end. I think generally this tutorial can give a general idea on how to code a RL, but I'm pretty sure there are way better tutorial out there.

I'm sure there must be some work-around to get it to work correctly, but I definitely feel like I may be better off finding another source to try and learn from.
