Persistent Minimap with GetTileExplored & SetTileExplored

Himmelweiss · January 2019

So, yesterday i was bored and played arround with the functions GetTileExplored & SetTileExplored so i am justly simply sharing it here.

Script is supposed to run for the Events "Area OnEnter/OnExit" and "Module OnPlayerRest".
So it saves the minimap vision/fogofwar state of the current area to the bio db on every area enter/exit and player rest.

Take/use it at your own risk because it was just a quick test, didn't really run an super hard test cycle with it.


const string MINIMAP_DB = "minimap_db";

void main()
{
    object oArea = OBJECT_SELF;
    object oPC = GetEnteringObject();
    if (oPC == OBJECT_INVALID)
        oPC = GetExitingObject();
    if (oPC == OBJECT_INVALID) {
        oPC = GetLastPCRested();
        oArea = GetArea(oPC);
    }

    if(!GetIsPC(oPC)) return;

    int iAreaHeight = GetAreaSize(AREA_HEIGHT, oArea);
    int iAreaWidth = GetAreaSize(AREA_WIDTH, oArea);
    string sAreaResRef = GetResRef(oArea);

    string sMap = GetCampaignString(MINIMAP_DB, sAreaResRef, oPC);
    string sX;
    string sY;
    struct sStringTokenizer stTok = GetStringTokenizer(sMap, ",");
    while (HasMoreTokens(stTok)) {
        stTok = AdvanceToNextToken(stTok);
        sX = GetNextToken(stTok);
        stTok = AdvanceToNextToken(stTok);
        sY = GetNextToken(stTok);
        
        SetTileExplored(oPC, oArea, StringToInt(sX), StringToInt(sY), 1);
        //SendMessageToPC(oPC, "explored sX: " + sX + " / sY: " + sY);
    }

    sMap="";
    int x;
    int y;
    for (x = 0; x < iAreaWidth; x++)
    {
        for (y = 0; y < iAreaHeight; y++)
        {
            if (GetTileExplored(oPC, oArea, x, y))
            {
                sMap += IntToString(x)+","+IntToString(y)+",";
            }
        }
    }
    
    SetCampaignString(MINIMAP_DB, sAreaResRef, sMap, oPC);
}

I don't know if anyone else is using this code, but your snippet above was enough for me (a total NWN scripting newbie) to implement on our test server. We'll shake it a little to see if we have any problems before moving to the live server, but wanted to share that I am thankful for this quality of life improvement!

If anyone else is having trouble understanding the above code, here it is properly formatted -

const string MINIMAP_DB = "minimap_db";

void main()
{
    object oArea = OBJECT_SELF;
    object oPC = GetEnteringObject();

    if(oPC == OBJECT_INVALID)
        oPC = GetExitingObject();

    if(oPC == OBJECT_INVALID)
    {
        oPC = GetLastPCRested();
        oArea = GetArea(oPC);
    }

    if(!GetIsPC(oPC))
        return;

    int iAreaHeight = GetAreaSize(AREA_HEIGHT, oArea);
    int iAreaWidth = GetAreaSize(AREA_WIDTH, oArea);
    string sAreaResRef = GetResRef(oArea);
    string sMap = GetCampaignString(MINIMAP_DB, sAreaResRef, oPC);
    string sX;
    string sY;
    struct sStringTokenizer stTok = GetStringTokenizer(sMap, ",");

    while(HasMoreTokens(stTok))
    {
        stTok = AdvanceToNextToken(stTok);
        sX = GetNextToken(stTok);
        stTok = AdvanceToNextToken(stTok);
        sY = GetNextToken(stTok);
        SetTileExplored(oPC, oArea, StringToInt(sX), StringToInt(sY), 1); 

        //SendMessageToPC(oPC, "explored sX: " + sX + " / sY: " + sY);
    }

    sMap = "";

    int x;
    int y;

    for(x = 0; x < iAreaWidth; x++)
        for (y = 0; y < iAreaHeight; y++)
            if(GetTileExplored(oPC, oArea, x, y))
                sMap += IntToString(x) + "," + IntToString(y) + ",";

    SetCampaignString(MINIMAP_DB, sAreaResRef, sMap, oPC);
}

I removed a few extraneous braces and made the layout of a few of the lines consistent with the rest of the code.

This works well and it's much appreciated!
