[Plugin] Colour N-Gons v1.0 (17/4/12)

TIG

A 'one-liner' needs to be copied+pasted+<enter> into the Window > Ruby Console to do its stuff.
In this case it works on the current Selection, and changes the material of all selected faces that have the given number of edges...

Rich O Brien

does this thing need a module/class etc?

Also does it need a def? All this is still greek to me

TIG

A 'one-liner' stands as it is - it's just like typing any commands into the Ruby Console.
Of course you could make it a 'module' that has a 'menu' item and a 'dialog' for the number of faces etc etc...

Rich O Brien

let's not go there. As much as I need to highlight quads I don't want to tear my hair out. There's not much left after last time

The orange is just comments - they do nothing.

I didn't test it before posting - because now I can 'fix' it for a grand fee!
Gimme the error message and a wallop of money!

Rich O Brien

error message below....

There's none?

thomthom

Ah - found a typo: def self.self.colour_ngon - should be def self.colour_ngon. I updated my post.

Rich O Brien

That little fella was highlighted in Notepad++. So it finds the errors for you.

Rich O Brien

Updated first post with plugin.

Thanks Thom

Ah, neophyte question, what is the defintion of an Ngon?

Rich O Brien

a polygon with n sides

a quad is a 4-gon

a tri is a 3-gon

etc....

Hi John

Gaieus

What about a bi?

JClements

Gai...

Just let bi-gons by bygones.

they go either way

Rich O Brien

@John

I forgot Oregon

pilou

a bi-gone = a segment line !
A one gone = a point !
0 gone = void

pilou

a cool thing will be something like that
colour ngons > 6 and < 10 (just example)

..and you will want these to be randomly painted also?
