Thank you for the links. Much appreciated :-)
I've tried on_gui_confirmed
too, but that event never gets raised for me.
According to docs, it seems to be used for confirming other inputs, like a text field, by pressing ENTER; its not entirely clear for me if that should or shouldn't include the confirm window key. Since I don't have inputs, and the event is not responding, it suggests it doesn't?
I've tried to run your mod to try and confirm if it does work for you due to text fields or similar. But all the buttons remained disabled? Placing a car, entering a car and placing stone tiles didnt make a difference. I suppose there's other requirements before it starts working that aren't immediately obvious to me. I was on fulgora with only a small stone patch. Perhaps it needs a more elaborate road system? I'll try that later when I have more time. :-)
The keybinds you're pointing me to, are custom ones. I suppose I could map 'E' myself, but if a player then rebinds 'Confirm window' to another key, I am assuming that won't update my keybind? Not ideal, but I suppose another alternative to explore.
I'll try some more things at a later time. Thanks for the help so far.
