How to add a label for a negative number in the AI-Options?

[Steffl]

Hi,
I have a problem. This code doesn't work:

Code: Select all

AddSetting({name = "maintain", description = "Maintain existing shuttle services every ... days", min_value = -1, max_value = 9999,easy_value = -1, medium_value = -1, hard_value = -1, custom_value = -1, flags = 0|AICONFIG_INGAME});

		AddLabels("maintain", {_-1="decide automatic",_0="never"});

I don't know how to add a Label to a negative number. I tried with adding spaces but I wasn't successful.

If I remove " _-1="decide automatic" " it works, but it would be very nice if I could avoid one additional option for the automatic maintainance interval.
I plan a new AI-Project and I already see, that I will need to use a lot of options to interact with it. So place in preference menu is very valuble.

Maybe someone had tried this too and can help me.

You could try if this works:

Code: Select all

AddLabels("maintain", {"_-1"="decide automatic",_0="never"});

No, this doesn't work, too. But thanks.
Maybe it's currently not possible. and would need changes in Openttd itself.

You can use rawset which takes key as first argument and value as second argument:

Code: Select all

local labels_table = {_0="never"};
labels_table.rawset("_-1", "decide automatic");
AddLabels("maintain", labels_table);

Cool, this works. Good trick.
Thanks Zuu.
