I was looking at the discussion of Max5/Max6 helpfiles but I think this is a slightly different issue
As I’m learning about Jitter I find the helpfiles a lot less helpful than for Max: a lot of jargon (what is a slab?) but it also seems some bits are missing from the reference: especially arguments.
For example, in the tutorial you’ll find a matrix defined: [jit.matrix 4 char 320 240} but in the reference there is only a ‘messages’ and an ‘attributes’ section, no ‘arguments’
I did a quick check for some other jitter objects; they all seem to be missing the ‘argumetns’ section from the reference. Is there any reason for this?
The four arguments you mention are common to a large number of Jitter objects. They certainly used to be explained quite early in the Tutorials, but this may have changed since I worked my way through them. And the explanation only came once, so if you missed it, you were sorta out of luck.
Briefly, the arguments are, in order: planecount, celltype, matrixwidth, matrixheight.
The info that you’re referring to is in Jitter Tutorial 2: Create a Matrix, as Peter mentioned. Also, although it’s frustratingly hard to find, the page on Jitter Matrix Operators, which explains messages, arguments, and attributes common to all Jitter matrix operators is important reading.
