How do I compare two arrays in a if? Do I need to iterate the comparison in a foreach or is there an easier way?

float maxdist = 0.5;
int maxpoints = 15;

int current[]  = pcfind(0, "P", @P, maxdist, maxpoints);
int orig[] = pcfind(1, "P", @P, maxdist, maxpoints);

// Well, this doesn't work...
//
// i@group_broken = (current[] != orig[]) ? 1: 0;

float maxdist = 0.5;
int maxpoints = 15;

int current[]  = pcfind(0, "P", @P, maxdist, maxpoints);
int orig[] = pcfind(1, "P", @P, maxdist, maxpoints);

// ...or this...
//
// i[]@current = current;
// i[]@orig = orig;
//
// i@group_broken = (i[]@current != i[]@orig) ? 1: 0;

not 100% sure , but I assume if you need to test the arrays are identical to each other you would need to loop over and compare each element

you can break the loop as soon as one of the values fails the comparison test something like this:

int tester = 1;
int count = 0;
if( len(array1) == len(array2)
{
while( tester )
if( count = len(array1 ) )
tester = 0;

if( array1 == array2 )
count += 1;
else
tester = 0;
}

Wow, I thought I had it set so I get a mail when someone replies - apparently not. Much appreciated, I'll check it out, see if it works for the setup I was messing with.

I have noticed the same thing with not receiving notifications

I just ran a quick test of my previous slap code and noticed a few errors, here is a working example run in a detail wrangle:

i[]@ar1 = {0,1,2,3,4};
i[]@ar2 = {0,1,2,3,5};

int tester = 1;
i@result = 0;
int count = 0;
if( len(@ar1) == len(@ar2))
{

    while(tester)
    {
        if( count == len(@ar1) )
            tester = 0;
            
        if( @ar1[count] == @ar2[count] )
        {
            count += 1;
            @result = 1;
        }else{
            tester = 0;
            @result = 0;
        }
    }

}else{

    tester = 0;
}

the detail attr result will return 0 if the array is different and return 1 if they are equal

it looks like my code got munged a bit…all the brackets got removed…fixed it now
