[Closed] Recursive problem

Aug 01, 2007 2:30 pm

Hi ive got this script which works its why through multisubs. but it has a slight problem when a multisub doesnt have sequential IDs i.e. if the numbers run 1,3,4,6,7,8,10 as the missing ID’s are coming back undefined, then it spits an error out because undeffined doesnt have numsubs.

 
 
fn getSubAnims theParent = (
 
for i = 1 to theParent.numsubs do ( --for each sub-anim
 
append theMats theParent[i] --add to the array and then call recursively 
 
try(getSubAnims theParent[i].object)catch(getSubAnims theParent[i])
 
)--end i loop
 
)[size=2]--end fn
 
[/size]

i have tried putting this into the code above

if theParent == “undefined”then print “error”else

but doesnt seem to stop it.

[color=white]any ideas ? [/color]

Try

fn getSubAnims theParent =
(
	for i = 1 to theParent.numsubs do
	(
		if theParent[i] != "undefined" then
		(
			-- For each sub-anim
			append theMats theParent[i]
		
			-- Add to the array and then call recursively
			 try(getSubAnims theParent[i].object) catch(getSubAnims theParent[i])
		)
	) -- End i loop
) -- End fn

ok i put that back in but im getting the same error.

 
 
[color=white]fn[/color] getSubAnims theParent =

(

	 for i = 1 to theParent.numsubs do

	 (

	   if theParent[i] != "undefined" then

		 (

				 append theMats theParent[i]-- For each sub-anim

				 try(getSubAnims theParent[i].object) catch(getSubAnims theParent[i])

				 print theParent[i]

				 print i

			)

	 ) -- End i loop

) [size=2][color=white]-- End fn

[/color][/size]

and this is called with the following

 

theMats = for o in selection where o.material != undefined collect o.material

for m in theMats where 

(m != undefined) do getSubAnims m --call the recursive function for each material

this is the error that im getting
