Thor's collection thread for DFI-related questions

thor2950 · Sep 16th 2021

Hi,

I need to construct a specific DFI to be fitted in my Copenhagen bus stops.

Like these two:

My question is: After creating the object in Blender, what textures do I need? Like background/nighttex/alpha channel? And what should each of these contain?

And just a very short general explanation for a dumbhead like me: How should these textures then be configured script-wise?

Moin,

Für meine Kopenhagen-Karte brauche ich ein DFI für die Haltestellen, wie im Bild von oben anzuschauen ist.

Die Frage, die ich habe, ist: Nachdem ich den Objekt in Blender gebaut habe, welche Texturen brauche ich eigentlich? Hintergrund/Nacht/Alpha-Kanal? Und was müssen sie enthalten?

Und nur ganz kurz für einen Dummkopf wie ich: Wie muss ich die im Script konfigurieren?

Best regards/Liebe Grüße,

Thor

Hi Thor,

since this is a complex undertaking, I cannot write you a simple recipe here. But first the most important:

- in your case it is sufficient to create a text texture ( https://www.lotus-simulator.de…-and-drawing-on-textures/ ) that directly draws the content of a string variable and uses black as color.

- the standard texture contains only a dark display (not black, that doesn't look realistic!)

- then place a rectangular polygon two or three cm above the display. Its blend mode is set to alpha, the standard texture is the text texture and the night texture is a completely white texture.

- We will take care of the script when you are ready to write characters to the text texture using the string variable. But if you want to have a look already: https://www.lotus-simulator.de…em/#3.2-Script-Funktionen

Now that I've got most of the display features to work so far (showing the line number and destination at the correct spots), I still need to get the "time to departure" working. Using the variable "DT_Plan" from "TStatPISTrip" only outputs the scheduled departure time of the day, and not the time to depart.

What functions/variables do I need to retrieve this information from the timetable and output it as "time to departure"? Converting to minutes I can probably figure out myself.

EDIT: Figured it out myself.

Code

//This function calculates the time to departure in minutes to be written on the display. The parameter is the "DT_Plan" single from a TStatPISTrip type.
function RetrieveMinutestoDepart(Scheduled_depart: single): string;
var
min: integer;
CurrTime: single;
begin
//Retrieves the current time of the day as minutes
CurrTime := (TimeOfDay * 24) * 60;
//Converts the DT_Plan time to minutes
Scheduled_depart := (Scheduled_depart * 24) * 60;
//Calculates the time to departure in minutes
min := trunc(Scheduled_depart - CurrTime);
//Writes the result as the functions return string
result := IntToStrEnh(min, 2, '0');
end;

Hello again,

With the current configuration of my script, the display doesn't include special characters, only the line number itself.

Example:

I have the line 250S, which consists of the line number + the special char code 2.

In the script, the data gathering is done with this procedure:

Code

procedure GetInfo;
begin
//Creates a temporary list of data from the timetable for the given amount of time specified in $timespan
StatPIS_GenerateTempDataList(Self, $timespan);
//Sorts the list after departure time(parameter 0, at the moment the only one)
//StatPIS_SortTempList(Self, 0); I øjeblikket uden funktion grundet ingen sorteringsmuligheder
//Writes the number of trips from GenerateTempDataList to datacount
datacount := StatPIS_GetTempDataCount(Self);
//Checks if any trips are present on the list (> 0). If yes, then write the trips from the list (index #) to "data_line#"
if datacount > 0 then
BEGIN
data_line1 := StatPIS_GetTempListData(Self, 0);
data_line2 := StatPIS_GetTempListData(Self, 1);
data_line3 := StatPIS_GetTempListData(Self, 2);
data_line4 := StatPIS_GetTempListData(Self, 3);
END;
//Writes the length of the line strings into their respective Linestr_Length. This is used to shift the number right on the display.
Linestr_Length1 := TexGetTextLenPixel(Self, data_line1.Line, Font);
Linestr_Length2 := TexGetTextLenPixel(Self, data_line2.Line, Font);
Linestr_Length3 := TexGetTextLenPixel(Self, data_line3.Line, Font);
Linestr_Length4 := TexGetTextLenPixel(Self, data_line4.Line, Font);
Dest_Length1 := TexGetTextLenPixel(Self, data_line1.Terminus, Font);
Dest_Length2 := TexGetTextLenPixel(Self, data_line2.Terminus, Font);
Dest_Length3 := TexGetTextLenPixel(Self, data_line3.Terminus, Font);
Dest_Length4 := TexGetTextLenPixel(Self, data_line4.Terminus, Font);
end;

So, does the GetTempListData simply not include special characters, or what do I need to do to add this to the line variable?

Until now, that's unfortunately correct und impossible, but we will add this feature in future!
