Problem with array definition in script

[Ats]

Hi.
I'm currently simplifying the exported text from my Sheet to my ZGE project. So I'm trying to declare arrays in script.

Instead of doing this:

Code: Select all

<?xml version="1.0" encoding="iso-8859-1" ?>
<ZApplication Name="App" Caption="ZGameEditor application" FileVersion="2">
  <OnLoaded>
    <ZLibrary Comment="Constants" HasInitializer="1">
      <Source>
<![CDATA[
{
  Alphabet.SizeDim1 = 39;
  Alphabet[0] = "A"; Alphabet[1] = "B"; Alphabet[2] = "C"; Alphabet[3] = "D"; Alphabet[4] = "E"; Alphabet[5] = "F"; Alphabet[6] = "G"; Alphabet[7] = "H"; Alphabet[8] = "I"; Alphabet[9] = "J"; Alphabet[10] = "K"; Alphabet[11] = "L"; Alphabet[12] = "M"; Alphabet[13] = "N"; Alphabet[14] = "O"; Alphabet[15] = "P"; Alphabet[16] = "Q"; Alphabet[17] = "R"; Alphabet[18] = "S"; Alphabet[19] = "T"; Alphabet[20] = "U"; Alphabet[21] = "V"; Alphabet[22] = "W"; Alphabet[23] = "X"; Alphabet[24] = "Y"; Alphabet[25] = "Z"; Alphabet[26] = "0"; Alphabet[27] = "1"; Alphabet[28] = "2"; Alphabet[29] = "3"; Alphabet[30] = "4"; Alphabet[31] = "5"; Alphabet[32] = "6"; Alphabet[33] = "7"; Alphabet[34] = "8"; Alphabet[35] = "9"; Alphabet[36] = "-"; Alphabet[37] = "."; Alphabet[38] = " ";
}]]>
      </Source>
    </ZLibrary>
  </OnLoaded>
  <Content>
    <Array Name="Alphabet" Type="2" SizeDim1="39"/>
  </Content>
</ZApplication>

I'd like a simpler :
string[39] Alphabet = {"A","B","C",...};

But I get 'Assignment destination must be variable or array: Alphabet'

The problem is that even the example in the Help file of ZGameEditor is not working:
byte[] data = {1,2,3,4}; // initialization of 1D array of bytes

Hi Ats,

That syntax can only be used to declare and initialize local arrays .. like this:

Code: Select all

<?xml version="1.0" encoding="iso-8859-1" ?>
<ZApplication Name="App" Caption="ZGameEditor application" FileVersion="2">
  <OnLoaded>
    <ZExpression>
      <Expression>
<![CDATA[//

int[] code = {90210, 33162};

for(int i=0; i<code.SizeDim1; i++)
{
  trace(intToStr(code[i]));
}

//

string[] name = {"Beverly Hills", "Miami"};

for(int i=0; i<name.SizeDim1; i++)
{
  trace(name[i]);
}]]>
      </Expression>
    </ZExpression>
  </OnLoaded>
</ZApplication>

For global arrays you might as well use the "Persistent" feature.

Thanks Kjell. Now that I read your response, I feel that I already asked or saw that somewhere in the forum...
So I'll keep my array as is, since "Persistent arrays only supported for numeric data types".

Reading the Help file again, it's not clear that only the last line of the examples can't be declared in a ZLibrary, and only in a ZExpression.

Hi Ats,

So I'll keep my array as is, since "Persistent arrays only supported for numeric data types".

Perhaps your "Alphabet" example is just an example .. but in case it's a map for a font or name-entry dialog or something, you might as well store the ASCII codes instead. However, binary data in .zgeproj files is compressed using a not-so-straight-forward algorithm before being converted to a hexadecimal string

Reading the Help file again, it's not clear that only the last line of the examples can't be declared in a ZLibrary, and only in a ZExpression.

You mean as a global array defined in a ZLibrary, right? Since it works just fine inside a function:

Code: Select all

<?xml version="1.0" encoding="iso-8859-1" ?>
<ZApplication Name="App" Caption="ZGameEditor application" FileVersion="2">
  <OnLoaded>
    <ZLibrary>
      <Source>
<![CDATA[//

void call()
{
  string[] names = {"Peter", "Ray", "Egon"};

  for(int i=0; i<names.SizeDim1; i++)
  {
    trace(names[i]);
  }
}]]>
      </Source>
    </ZLibrary>
    <ZExpression>
      <Expression>
<![CDATA[//

call();]]>
      </Expression>
    </ZExpression>
  </OnLoaded>
</ZApplication>
