[0.14.4] [Rseding91] Error in on_gui_click causes uncloseable dialog

[mickael9]

If a lua error happens in the on_gui_click event handler, the error message will be shown but the user won't be able to close it.

Code to reproduce:

Code: Select all

script.on_event(defines.events.on_gui_click, function(event)
    error("oops")
end)

script.on_init(function(event)
    for name, player in pairs(game.players) do
        player.gui.center.add{type = "button", name = "crash_button", caption = "Click me!"}
    end
end)

I also noticed that the button is not created when creating a new save (only when loading an existing save). Is that a bug I should report?

on_init only runs ONCE when the mod is first installed into a save. The first time a game is created there are NO players in game.players until after on_player_created

if you move your code from on_init to on_player_created then it will run when your player is created, however it will not run on subsequent saves because your player is already created in that save.

Subsequent saves will need to use on_configuration_changed (code here will run anytime base or any mod is added/removed/updated) and on_load However on_load is special so make sure to read up on it!

Ah ok, makes sense

Congrats on your 500th post

Just wanted to write a report for this bug, and then saw this.

I don't recall we have this bug before even though I made many mistakes when making GUI, so I tested with different Factorio versions.
I can confirm that 0.13.20 doesn't have this bug, but it exists in all the 0.14 builds.

It seems that the button that causes error is still having higher priority for interactivity than the error dialog despite being drawn under the dialog. You can check this by hovering the button.

Just wanted to say that I'm getting the same problem here, got a GUI button that causes an error, and I cannot click anything after the 'Notice' comes up.
