Hi,
I'm working on a Globoid worm & wheel using the nodeditor.
To check if the worm & wheel are not colliding I made a animation nod file
that checks by doing a boolean operation every step of the animation.
It would be better if I could log the steps and boolean results rather than manually checking every step.
is it possible to record and log boolean event with the nodeditor.
Cheers
Barry

Hi Barry,

This is what I use to record variables to a log within the Node Editor. It writes to a file, but is not accessible until exiting the node editor.

datapop = moi.filesystem.openFileStream('c:\\temp\\datapop.txt', 'w');

// Usage;
for (var i = 0; i < 10; i++) {
datapop.writeLine("Title " + i);
}
;

// Exit node editor to view results.

Hi Wayne,
thanks for the code but how do I implement it.
Cheers
Barry

Hi Barry,

Create or verify this directory exists on your PC:
'c:\temp'

Here is a simple node to record the XYZ values of points.

Save this file as '_PointDetails.js' in the ext file of the node editor.

Start the node editor and load the PointDetails node that was just registered.

Attach a node with a point array output.

Run the node. (No output node required.)

Exit the node editor and exit MoI3d.

Look in the directory for the file 'c:\temp\datapop.txt'. It should be populated with the points detail.

   var datapop = moi.filesystem.openFileStream('c:\\temp\\datapop.txt', 'w');

        this.boxcolor = "#F05";
        this.addInput("Pts", "pointarray");
		this.addOutput("", "pointarray");
	}

	PointDetails.title = "PointDetails";

	PointDetails.prototype.onExecute = function () {
		if (!this.isInputConnected(0)) {

			pt = inp.getElement(i);
			x1 = pt.data[0];
			y1 = pt.data[1];
			z1 = pt.data[2];

            datapop.writeLine("X " + x1 +" Y " + y1 +" Z " + z1);

        this.setOutputData(0, ptArray);
