In maxscript there is:
meshop.setVertAlpha <Mesh mesh> <intmapChannel> <vertlist> <float alpha>
But i want set alpha value just for 1 single vertex and not the complete vertlist, is there a way? I have not found a version of that function that acepts jus 1 index, but I am really new to max, so psibly I just mised something.
meshop.setVertAlpha() takes an array, bitarray or an integer.
So with:
meshop.setVertAlpha msh -2 1 0.5
I can set the firs map vertex of msh chanel -2 to (0.5, 0.5, 0.5), right?
Yes, I suppose you can.
(
delete objects
boxes = for j = -1 to 1 collect converttomesh (box pos:[j*30,0,0] showvertexcolors:on vertexcolortype:2)
meshop.setvertalpha boxes[1] -2 #(2,7) 0.25 -- array
meshop.setvertalpha boxes[2] -2 #{3,6} 0.25 -- bitarray
meshop.setvertalpha boxes[3] -2 5 0.25 -- integer
)
I checked it myself and it worcks. But what the diference between array and bitarray? Like mentioned, really new to maxscript.
You are completely wrong in your assumptions, as well as in posting this kind of comments.
I asked myself this very same question the first time I heard about arrays and bitarrays.
And it seems we are not alone, otherwise there wouldn’t be an entry for this in the Autodesk Help. Don’t you think?
BTW: Arrays and BitArrays are not exclusive of MaxScript.
Sorry for the misunderstanding, maxscript is not my only problem, seems like english is even a biger one.
[What is the differences between Arrays and BitArrays?
do you want to know a difference between using these types (and a reason) for this (or this kind of) function?]( https://knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/2016/ENU/MAXScript-Help/files/GUID-8E73B891-4616-49D9-A34C-FCC3206DDD92-htm.html )
In first place, would like to know the diference between using the function with array and bitArray. Hope, was able to explain it correctly now, like mentioned english is my other problem.
