SlimDX and Parsing .X Files
- by P. Avery
I'm trying to parse a .x file using SlimDX. I can create the XFile object and register templates but I'm having problems with the enumeration object. The enumeration object has a child count of 0 for a file I know to have valid data. Here is code to create file, enumeration, and data objects:
public void Parse(string filename, string templates, ref Frame aParam)
{
XFile xfile = null;
XFileEnumerationObject enumObj = null;
XFileData dataObj = null;
// create file object
xfile = new XFile();
// register templates
if (xfile.RegisterTemplates(XFile.DefaultTemplates).IsFailure)
{
Console.WriteLine(Result.Last);
xfile.Dispose();
return;
}
// create enumeration object
enumObj = xfile.CreateEnumerationObject(filename, System.Runtime.InteropServices.CharSet.Auto);
if (enumObj == null)
{
xfile.Dispose();
return;
}
// get child count( returns 0 here )
long ncElements = enumObj.ChildCount;
for (int i = 0; i < ncElements; ++i)
{
// never reached...
dataObj = enumObj.GetChild(i);
if (dataObj.IsReference) continue;
try { Parse(dataObj, ref aParam); }
catch (Exception e) { e.Write(); }
finally { dataObj.Dispose(); }
}
enumObj.Dispose();
xfile.Dispose();
}
...There are no exceptions thrown by this function...the child count is 0 so the conditional loop breaks right away, the file objects are disposed of and the function returns...
Here is .x file...a simple cube:
