opdigit equivalent

[papicrunch]

Hi,

 

Is there an equivalent of " opdigits " expressions in Vex ?

 

thank

I don't think there is, the only way I know is to use the opdigits in a parameter and then reference that in VEX code.

so bad the opdigits expression is really slow

 

thx

[papicrunch]

just repost the goal of that on sidefx forum

 

 

 

hi, 

Is there a way to pass an attribut when packing an object, as the "name" can be retrieved to intrinsic_fragmentname. 

One solution that I found is to concat my custom attribut in the name then retrieve it with the opdigit expression. (see the hip) 
But the opdigit expression is really slow to evaluate and with a lot pack primitive is not a viable solution. 

thank, 

papi

I am not sure exactly what you are doing but you can split the string in VEX using the split function and then convert the last element into an integer using the atoi function.

great idea but i dont find a way to use this function in the attributWrangle sop,

 

how can i declare an array string ?

Vex can manipulate only the data that you pass to it. So to get operator number you need to pass it somehow.

thank you,

 

the working hip if interested

 

have fun

Your file has incomplete asset definition but you don't need a new SOP to do this. Just use something like this in AttribWrangle

 

string s = primintrinsic(ch("parm"),"fragmentname",@primnum);
s@__foo=s;
string items[] = split(s, "_");
s@first= items[0];
