One of the String arguments supplied was not a string

[Cogliostro]

Okay, going a bit bonkers here.  Created an ENUM, built an array with it, "Displayed" the contents, and it all shows up pretty as a picture.  Then I move the ENUM and ARRAY to Global Script and try to write all of the exact same text into a GUI Label, and I get an error: "One of the String arguments supplied was not a string."  If I eliminate the string it works, so *most* of the code it valid, but how do I get it to display the name?!

Code: ags

//Global Script.ash
struct Place {
  String Name;
  int ID;
  int CurRoom;
  int Order;
  int PosX;
  int PosY;
  int ObjNum;
};
      
Place Details[11]

THIS CODE WORKS!

Code: ags

function ShowOff() {
    Display("Name: %s[ID: %d[PosX: %d[PosY: %d[Room: %d",
      Details[DetailProp].Name,
      Details[DetailProp].ID, 
      Details[DetailProp].PosX, 
      Details[DetailProp].PosY, 
      Details[DetailProp].CurRoom);
}

But this code generates the error?!  What's the difference?!

Code: ags

//Room Script
function room_Load()
{
  lProp.Text=String.Format("Name: %s[ID: %d[PosX: %d[PosY: %d[Room: %d",
      Details[DetailProp].Name,
      Details[DetailProp].ID, 
      Details[DetailProp].PosX, 
      Details[DetailProp].PosY, 
      Details[DetailProp].CurRoom);

Any help would be appreciated,

A solution - sort of...

I narrowed down the cause of the problem.  I ran the ShowOff() function in both rooms.  In the room where I populated the data into the array, DETAILS, it worked.  In the other room, it failed.  Now, when I moved the Array into the GlobalScript.ASH, because I wanted the values I entered in the one room to be available in the next, but apparently that isn't going to happen.  So, for the moment, I moved the ARRAY and ENUM into the headers of both rooms, and entered the data in twice.  Was there supposed to be a way to make the array data accessible from both rooms?

P.S.  I'm going to let this kick around for a day or so before flagging it resolved.

The problem is you declared Place Details[11]; in the header, not the main script. Since the header is put on top of all scripts "below" it, that created a separate array for each room.
An int defaults to 0, but a String defaults to null, which isn't a String (a String is actually a pointer to a char[]).

You have to do:

Code: ags

// header

// struct definition here

import Place Details[11];

Code: ags

// main script

Place Details[11];
export Details;

Hmm... still having trouble...

Global Script

Code: ags

Place Details[11];
export Details[11];

Global Header

Code: ags

struct Place {
  String Name;
  int ID;
  int CurRoom;
  int Order;
  int PosX;
  int PosY;
  int ObjNum;
};

import Details[11];

Getting the error: Failed to save room room1.crm; details below
GlobalScript.ash(19): Error (line 19): expected variable or function after import, not 'Details'


Of course, if I change the IMPORT line to read:

Code: ags

 import Place Details[11];

I get the error: GlobalScript.asc(717): Error (line 717): export parse error at '['

If I updated the line in the global script to include the Struct type: PLACE. 
Then I get: GlobalScript.asc(717): Error (line 717): invalid export symbol 'Place'



I've imported functions before, but doing this with a custom array is driving me nuts!

Either copy and paste my code or look at it again very carefully.
I'm confident it will work if you use it exactly as I put it (you haven't done so yet).

Kris!

when I exported it at the bottom of the global script I included the brackets and size of the array!!  Once I cleared that out, everything worked like a charm.  For the record, you just earned a spot in the credits!

Thanks,

You're welcome, glad it's working

Btw, you can move the export line directly below the declaration line, it doesn't have to be at the bottom of the script.
