Re: import flame tracker to XSI?

[Arvid Björn <arvid.bjorn(at)palladiumfilm.com>]

Hey Stefan, here's a real simple one based on the .ascii-file (had some 
time to spare)
Apply changes where necesarry (ie. filename and null object)

//--------------------
var oFSys = new ActiveXObject("Scripting.FileSystemObject");

var f = oFSys.GetFile("C:\\test.txt");
var oS = f.OpenAsTextStream(1, 0);

var ts = ""; var nf = ""; var nx = ""; var ny = "";

while(!oS.AtEndOfStream)
{
   ts = oS.ReadLine();
   nf = ts.substr(3,4);    // frame number
   nx = ts.substr(11,6);    //x value
   ny = ts.substr(20,6);      // y value
   SetKey("null.kine.local.posx", parseFloat(nf), parseFloat(nx), null);
   SetKey("null.kine.local.posy", parseFloat(nf), parseFloat(ny), 
null);   
}

oS.Close();
//--------------------
