@James,

Create a test directory for the Node Editor and call it with a shortcut. This way you keep the original directory and have a test area for playing with nodes.

moi.ui.createDialog( 'moi://appdata/nodeeditortest/index.html?scheme=Light', 'resizeable,defaultWidth:1000,defaultHeight:1000', moi.ui.mainWindow );

The original and test area node editor use the same MOI instance so the nodes are viewable in both the original and test area editors.

You can cut and paste nodes between the node editors and run them separately. How cool is that?

Yes, thank you for the code to address new arrowheads. This will be a real boon for future development of vector nodes.

Thanks for the tip of parallel NE for testing coding. This is indeed a "cool" technique.

Thanks again,

Question about writing a new node.

The scripts in MoI often have Functions{} in their code.

The node programs do not seem to use such Functions{} very much.
Instead they use ...prototype...function().
So to use a function from a script, in a node, should they be written as ...prototype...function()?

Or,
I see that in the Lib folder under nodeeditor\nodes\extensions, there is a file called basicFunctions.js,
which is full of miscellaneous functions.

So when writing a node which uses a MoI script with functions, can or should I put the needed functions in a new lib file called, for example, basicFunctions2.js?

- Brian

It seems that the functions in basicFunctions.js can be (re-)used in any new node?

Hello, Brian,

the prototype function gives the objects created by using the nodeeditor a uniform interface for the processing. Same method names for the various
Knots. So every code of the node creates a type. Later by using the node editor you create objects of these types with a uniform interface of functions.
You can of course use the functions in basicFunctions.js and also create a basicFunctions2.js. You can also write your functions to the same file as your nodes.
For more frequently used functions, it makes sense to store them in a library.

Have a nice day

Thank you Karsten.

Two additional related questions:
1. Where would a function go in a node? Inside the .prototype.onExecute = function (), or
just before it?
I have not found any examples, as far as I know.

2. Is it necessary to "link" say basicFunctions2.js somewhere? Or is this already set up?
(I have not searched for an example useage of basicFunctions.js yet.)

Hello Brian,

you can find examples where to place "normal" functions in vector.js. If you want to create a lib of functions you can place it in the libs folder under extensions. Max has made an autoload for files placed in that folder. So no link.

Have a nice day
Karsten

That information is very helpful.
Thank you Karsten.

Cool!
Does exist a trick for see if the are Macros or not ?
And i see (1-a)*b how do you enter (1-a) ?

Pilou,

>> Does exist a trick for see if the are Macros or not ? <<

Yes, the macros are darker, but there are no macros used in example above.

>> And i see (1-a)*b how do you enter (1-a) ? <<

As well as preset functions, you can type custom functions into Math node's F field.
See image below

>> Cool <<

Cheers

I must retry because this F case return me nothing! :)

---

After typing in an equation in the F field, press enter, otherwise the entry goes away.
(Slightly annoying). When typing a more complex equation, save a partly correct entry, then re-edit,
otherwise partial work could be lost.

Now with Wayne's latest update to ImgSampler node ( https://moi3d.com/forum/index.php?webtag=MOI&msg=9581.57 ) it's possible to have 3 images of RGB channels (separated in photoshop) output to interleaving dot screens as shown.
