So I've been grappling with jit.anim.path and I came across this post from a few years ago: 

https://cycling74.com/forums/jit-anim-path-has-no-matrixcalc-function-any-howto/

Was this functionality ever updated-- is it possible to use matrixcalc now? I 'm trying to create a variable amount of jit.anim.path objects and the accompanying jit.gl.gridshape objects to animate along them, but I can't get the position information. I'm new to this, so maybe I'm using matrixcalc wrong. I just keep getting 'undefined' when I try. (I'm sorry I can't post my patcher until later tonight, I'm using Jitter on a separate maching that has no Internet).

I tried the patch and script from that post, and it works great for one path line, but I need multiple lines. Would changing the name of the jit.anim.path object each time I put in new points make a new instance, and therefore a new line?

yeah please post your patch when you get a chance, and i'll try and make some suggestions.

So here's my patch and the accompanying js code. When you hit 'drawline', a new line is drawn on-screen with a torus at the starting point of that line. But past that, I can't work out how to feed the path into the grid shape to animate the torus. The only example I could find of using matrixcalc() is in Jitter Tutorial 45, and I think I'm just not understanding what arguments I need to put in. I thought I should give it a blank matrix to store the x,y,z position at each bang, but that didn't seem to work. How do I get the position data that jit.anim.path is providing?

ok, i understand better what you're attempting.

you don't need to deal with matrices at all for this. jit.anim.path animates it's target objects internally, so all you need to do is provide a target object name to the "targetname" attribute.

animPaths[pathcount].targetname = glShapes[pathcount].name;

and then call the start message (messages in JS are methods, so you need the parentheses):
