[1.1.70] commands.add_command does nothing during script.on_load and script.on_init

[ZwerOxotnik]

Expected:

• New commands during/after script.on_init and script.on_load using commands.add_command

Code:

Code: Select all

function add_commands()
	commands.add_command("test", 'test', function()
		game.print("test")
	end)
end

script.on_init(add_command)
script.on_load(add_command)

Steps to reproduce:

• Download

  and place it as scenario
• Load "test_add_command" as a scenario
• Try to type in /test in the chat
• Save the game
• Load the save
• Try to type in /test in the chat

Actual Result:

• There are no new commands after script.on_init and script.on_load

Notes:

• I didn't check other Factorio versions

After fixing the typo in the script (add_commands in the last two lines) the command is registered as expected.

[ZwerOxotnik]

You're right. However, I'm getting more and more confused.

30.985 Error ClientMultiplayerManager.cpp useful_book was registered for the following commands when the map was saved but has not re-registered them as a result of loading: candran and tl
30.985 Error ClientMultiplayerManager.cpp:99: MultiplayerManager failed: "" + multiplayer.script-command-mismatch + "
" + "
useful_book"
30.986 Info ClientMultiplayerManager.cpp:608: UpdateTick(14292533) changing state from(ConnectedLoadingMap) to(Failed)

For some reason, useful_book_0.20.3 doesn't add commands sometimes. I do the same actions and yet somehow I'm getting different results sometimes despite the same data. I don't know why and how. It did happen in singleplayer and in multiplayer. I'll publish logs as soon as I recheck it yet again with other people.

[ZwerOxotnik]

This is mine, multiplayer (not re-registered the commands) -> singleplayer (fine) + saved -> loaded the save (fine)

Do clients check commands before script.on_load? The server saved the world and loaded it, and it works fine now.

[ZwerOxotnik]

I need to check another thing, wait...

[ZwerOxotnik]

Alright, I have no idea what had been happening. I'll let you know if the case will occur yet again.

[ZwerOxotnik]

Never mind, it did happen, I'm kinda confused even more because I did the same action, and it worked fine in singleplayer.

1. That server disabled useful_book_0.20.3
2. Saved it
3. Loaded it
4. Saved it
5. Enabled useful_book_0.20.3
6. Loaded it
7. Other players can't join now because of the error

Hm, it seems like something is wrong with useful_book's data, but I'm not sure how it happened. I'll recheck it again later.

[ZwerOxotnik]

Never mind, the mod data were changed on on_configuration_changed event, but commands were added already. Case closed, probably.

[ZwerOxotnik]

Why is it allowed to happen on_configuration_changed after on_init for the same mod?

[FuryoftheStars]

Why is it allowed to happen on_configuration_changed after on_init for the same mod?

So that other mods can get the opportunity to make changes with the addition of your mod, if needed, I believe.

[ZwerOxotnik]

Sure, I mean this is a more specific case from the individual mod perspective, because the mod didn't change actually for itself since script.on_init happened for the mod already in the same situation. (I don't want to remove the data for other mods/scenarios)

[FuryoftheStars]

Sure, I mean this is a more specific case from the individual mod perspective, because the mod didn't change actually for itself since script.on_init happened for the mod already.

Yes, but most of the events don't fire for only one mod. on_init I think is one of the few that fires only for the mod that caused it.

on_configuration_changed, however, when it fires off, it does so for all mods.

[ZwerOxotnik]

Welp, I hope I understand it properly now, otherwise I'll write about it here again.
