Import array with wrangle

[sessionbeer]

Can some please help me with importing an array? I'm struggling with the documentation and searching the web.

I would like to import the previously created @near_array into a wrangle node.

 

Thanks

There are some problems in your build_array. Here is code as I would correct it to remove syntax and type casting errors.
 

float @near_array[];
float search_rad  = ch("max_rad");
int max_points  = int(ch("max_points"));
int success;        // Used as a flag to determine if the function returned a valid value.
 
int handle = pcopen(1, "P", @P, search_rad, max_points);
int i = 0;
while( pciterate(handle) ) {
    float result = pcimport(handle, "point.number", success);
    if (success) {
        @near_array[i] = result;
        i += 1;
    }
}

Once you have created the attribute it will exist downstream in the network (middle click on node to check). There is nothing special to do to import it. Simply reference the attribute in another wrangle downstream.

printf("%s\n",@near_array);

you should refer to it as:

i[]@near_array

so for accessing existing one from first input you will use:

printf("%s\n",i[]@near_array);

to create one that just contains point numbers as in your file, you can use pcfind() function directly

float search_rad  = chf("max_rad");
int max_points  = chi("max_points");
i[]@near_array = pcfind(1, "P", @P, search_rad, max_points);
