Returning each n iteration of a vex for loop

[Wideeagle]

Hi everyone I am encoutering an issue with a VEX code.  I want to offset a lot of uv island correctly on different UDIMS.  So here’s the idea.    
 

I have a wrangle inside a for each loop.  For the y offset its ok I do:

———————————-  

//getting current iteration of the for loop  

int iteration = int(detail(1,"iteration");

@yiter = iteration%chi(‘scale’);  

———————————-

 So if scale is equal to 5 my y offset will be like that:  

@yiter=1 for island 1

@yiter=2 for island 2  

[...]  

@yiter=5 for island 5  

@yiter=1 for island 6

[...]  

@yter=5 for island 10

 etc.... the value reinitializes itself each n iterations.  (n defined by my chi(‘scale’)  

 

Now for the x, I want it to be incrementing like that:  each time @yiter = 10 xiter = xiter + 1  
 

So it gives

 yiter=1 xiter=1 for island 1  

yiter=2 xiter =1 for island 2  

[...]  

yiter=5 xiter=2 for island 5  

[...]  

yiter = 10 xiter = 3 for island 10    

 

so xiter counts how many times yter is reaching chi(‘scale’)   and it needs to work for any given scale.

 

 Here is what I tried:  On input 1 I have my metaimport node.    
 

 —————————-

 int Scale = chi('Scale');

int nbloop = int(detail(1,"numiterations")); //total num of iterations for each island  

i@xiter = 0; //init xiter  

for (int i=0; i < nbloop;i++)

{    
     if(i%Scale == Scale-1)    

     {      
       i@xiter += 1;

      }

 }  

——————————    

 the thing is that in the end it gives me the total number of 10 iterations ( if I iterate 100 times then xiter=10 but I cant acces xiter each time it does the loop only after it looped nbloop times.    

Do you have any idea how can I get xiter at each incrementation?  Tell me if you need me to be clearer.  Thanks a lot !

you don't need any loops to move uv isands to specific UDIMs

but I have a huge number of pieces and I want to organize them on specific udims (lets say for example 10 pieces on 10 udims) thats why I need to iterate

you can assign different i@udim prim attribute value to each of them based on the island index (what are you curently iterate over? class attribute? name? )

do you have some simple hip showing your issue?
