[Closed] getting variable away from expression

I would probably do this so your function returns your value.

Have a look in the maxscript help docs for ‘return’

thanks, I will check return, I hope it will help

Unfortunately it wan’t work, I stick to max help if my understanding is right I made it as a function find_missing_plg with return find_missing_plg inside also return lInst and there is nothing again.

Try creating/defining your global variable before your function definition and then in your function pass this global variable as a by-reference argument so your function updates its value.

global lInst
 
function find_missing_plg &plgArray =
 (
	 local t = stringstream ""
	 apropos "*missing*" to:t
	 t = t as string
	 local l = filterstring t "
 "
	 local lMissingClasses = #()
 
	 for t in l do
	 (
		  if matchpattern t pattern:"missing*" then
		  (
			  local cls = execute t
			  if matchpattern (cls as string) pattern:"missing*" then
			  (
				   append lMissingClasses (getclassinstances cls)
				   plgArray = lMissingClasses
				   --plgArray now contains the array of your missing classes
			  )
		 )
	 )
)
--then call your function
find_missing_plg &lInst

I’m not sure I’ve defined your function correctly– but pass by reference should work for you.

closer but not enough. I need get information about missingplugin to label or messageBox so
in order to acheive it I put this code under your line –plgArray now contains the array of your missing classes. when I call find_missing_plg &lInst I have error. When I put insteand of -messageBox i get like 1000x #(). Below my code still not working:

function find_missing_plg &plgArray =
(
local t = stringstream “”
apropos “missing” to:t
t = t as string
local l = filterstring t “
“
local lMissingClasses = #()

 for t in l do
 (
	  if matchpattern t pattern:"missing*" then
	  (
		  local cls = execute t
		  if matchpattern (cls as string) pattern:"missing*" then
		  (
			   append lMissingClasses (getclassinstances cls)
			   plgArray = lMissingClasses
			   --plgArray now contains the array of your missing classes
			messageBox plgArray
		  )
	 )
 )

)
–then call your function
find_missing_plg &lInst

Well, I don’t have 3dsMax to play with at the moment… but it would be best to move the following code line: plgArray = lMissingClasses

outside of the for loop… so it only gets assigned once after the loop finishes. Search maxscript help for printing formated results of array values. Sorry I can’t be of more help at the moment.
