Script to remove all signs

[Sławek]

Hi,
I have a problem that I described here:
viewtopic.php?p=1266013#p1266013
I would like to remove all signs from the list.

List of signs.png (13.9 KiB) Viewed 3468 times

I found this class:
https://docs.openttd.org/gs-api/classGSSignList#details
this class has the Clear() function
https://docs.openttd.org/gs-api/classGS ... f69e9443f5
but I don't know how to use it.
I think it's easy to create a script using this function, but I've never done it. Can I ask for help on how to do this? Maybe someone could write me such a script?
Thank you and best regards

Code: Select all

local sign_list = AISignList();
	sgn_list.Clear;

From SuperLib:

Code: Select all

function _SuperLib_Helper::ClearAllSigns(except_tile = -1)
{
	local sign_list = AISignList();
	foreach(i, _ in sign_list)
	{
		if (except_tile != -1 && AISign.GetLocation(i) == except_tile) continue;
		AISign.RemoveSign(i);
	}
}

AIAI uses this function from user request:

Code: Select all

function AIAI::SignMenagement() {
	if (AIAI.GetSetting("clear_signs")) {
		Helper.ClearAllSigns();
	}
}

Thank you HGus for this code.
But I don't know how to use it.
Where should I enter this code?
Unfortunately, I've never scripted for OpenTTD.

[HGus]

Sorry. I thought you are an AI developer.

Find CPU-1.4.tar in your OpenTTD\ai or OpenTTD\content_download\ai folder.

Extract and edit main.nut

At line 448, insert this:

Code: Select all

local sign_list = AISignList();
	foreach(i, _ in sign_list)
	{
		AISign.RemoveSign(i);
	}

Repack main.nut into the tar file.

Rerun the game. The signs should be deleted in a few ticks. You can then exit and restore the original code.

Thank you.
Unfortunately, I'm not an AI programmer. I do some programming in various programming languages, but I've never programmed anything in OpenTTD before. I'm using Fedora 39.
I found the CPU-1.4.tar file in ~/.openttd/content_download/ai
I inserted this piece of code and it looks like this:

Code: Select all

{...]
    function CPU::Start() {
        AILog.Info("TestAI Started.");
        SetCompanyName();
        AICompany.SetAutoRenewStatus(true);
        //set a legal railtype. 
        local types = AIRailTypeList();
        AIRail.SetCurrentRailType(types.Begin());
        local towns = AITownList();
        //Keep running. If Start() exits, the AI dies.
        local step=-2;
        while (true) {
            this.Sleep(100);
local sign_list = AISignList();
	foreach(i, _ in sign_list)
	{
		AISign.RemoveSign(i);
	}            
            step+=1;
            while (AIEventController.IsEventWaiting()) {
{...]

I repackaged it into CPU-1.4.tar
I started the game, but I don't know what to click to make the signs disappear

It only works if the AI is running. If it died then all signs become un-owned and the only way to delete them is including the GS version in a Game Script if your game already included one. After modifying the script, reload a savegame with the AI still running.
