Hello James,
please try this code. It seems there is sometimes a timing problem with the copy/paste stuff. Very untested.
code:
// extractPts
function extractPts()
{
this.addInput("In","objectlist");
this.addOutput("Out","objectlist");
this.addOutput("ptarray", "pointarray");
}
extractPts.title = "extractPts";
extractPts.desc = "extractPts";
extractPts.prototype.onExecute = function()
{
var inObj = this.getInputData(0, moi.geometryDatabase.createObjectList());
var output = moi.geometryDatabase.createObjectList();
var selPts = moi.geometryDatabase.createObjectList();
var originXYZ = moi.VectorMath.createPoint(0, 0, 0);
var temp = moi.geometryDatabase.createObjectList();
var pts = new pointArray(false);
//////
moi.geometryDatabase.selectAll();
var existings=moi.geometryDatabase.getSelectedObjects(); //Locking the database objects
moi.geometryDatabase.deselectAll();
////////
if (inObj.length > 0 )
{ var tempname=getUID(6);
for(var i=0;i<inObj.length;i++){temp.addObject(inObj.item(i));temp.item(i).name=tempname;};
moi.geometryDatabase.addObjects(temp);
temp.setProperty('showPoints', 1);
moi.geometryDatabase.selectAll();
temp.setProperty('selected', 0);
existings.setProperty('selected', 0);
moi.geometryDatabase.copyToClipboardCommand(temp);
moi.geometryDatabase.pasteFromClipboard();
//setTimeout( doNothing, 500);
selPts=moi.geometryDatabase.getSelectedObjects();
for(var i=0;i<selPts.length;i++)pts.pushPoint(selPts.item(i).pt);
if(selPts.length>0)output = factory('copy',selPts,originXYZ,originXYZ,true);
moi.geometryDatabase.selectNamed(tempname);
temp=moi.geometryDatabase.getSelectedObjects();
moi.geometryDatabase.deselectAll();
var delfac = moi.command.createFactory( 'delete' );
delfac.setInput( 0, temp );
delfac.commit();
delfac.cancel();
existings=moi.geometryDatabase.createObjectList();
}
this.setOutputData(0, output);
this.setOutputData(1, pts);
}
LiteGraph.registerNodeType("Objects2/extractPts", extractPts);
Have a nice day
Karsten
p.s.: For V4 Michael will give us some new features in the API that will make a lot of things easier. |
