Sorting array

[Twizt3d]

I am adding values from one array into another array. How would I sort the second array by the index numbers of the first.

example:

PHP Code:

this.firstarray = {1,2,3,4,5,6,7,8,9,10,11,12,13};

for (temp.i = 0; temp.i<7; temp.i++){
   temp.random = int(random(0,13));
   this.secondarray.add(this.firstarray[temp.random]);
   //some algorthm to sort the second array by the index's of the first array
} 


Does this make any sense?

Eh you should be a little more detailed in your explanation, I'm not quite catching it.

And does this help at all?

PHP Code:

sortascending() - sorts the array in ascending order (smallest value first)
sortbyvalue(str, str, bool) - sorts the array by the specified variable name, you must also say what variable type it is (e.g. string) and if it should be sorted ascending
sortdescending() - sorts the array in descending order (highest value first)

ok Ill give some more detail:

PHP Code:

this.firstarray = {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten","Eleven","Twelve","Thirteen"};

for (temp.i = 0; temp.i<7; temp.i++){
   temp.random = int(random(0,13));
   this.secondarray.add(this.firstarray[temp.random]);
   //some algorthm to sort the second array by the index's of the first array
} 


this.secondarray will contain a random list of this.firstarray[] values. How could I put them in order. Example:

PHP Code:

this.secondarray = {"Two","Eleven","Three","Five","One","Twelve","Nine"}; 


Lets say the outcome of the for() made this.secondarray equal that.

How could I put this.secondarray in order from lowest to highest? So it will look like this:

PHP Code:

this.secondarray = {"One","Two","Three","Five","Nine","Eleven","Twelve"};

Well you would need an array of their correct positions obviously. Then make a second array in the function which will be the one you're going to return. Then use a for loop on the first array, and if you find that element in second array add it to the array you're going to return. It would end up in correct order.

PHP Code:

function onCreated() {
  this.firstarray = {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"};
  this.secondarray = sort({"Three","Nine","Five","Four"});
}
function sort(inarray) {
  temp.outarray;
  temp.i;
  temp.e;
  temp.c = inarray.size();
  temp.sortarray = this.firstarray;
  for (i = 0; i < sortarray.size() && c > 0; i ++) {
    e = sortarray[i];
    if (inarray.index(e) > -1) {
      outarray.add(e);
      c--;
    }
  }
  return outarray;
} 


That should be the simplest version.

Ill give it a shot Thanks a bunch

I feel like I made a mistake >_>
Or like I'm forgetting something.
I never did test to see if that works.

Edit: Just tested, it works.

Though that script would only work for that exact situation or something really similar. Its not exactly customizable and I'm too lazy to do anything more.

heh well my situation is a little more complicated so I will take that and see if I can use it. Really I am doing: temp.array.add(temp.array1[i]@"-"@temp.array2[i]); and trying to sort temp.array using temp.array1's values

  temp.take = 2; /* how many to take from first array */
  this.secondarray = this.firstarray;
  for (temp.i=0;temp.i<temp.len-temp.take;temp.i++){
    temp.random = int(random(0,temp.len-temp.i-.0000001));
    this.secondarray.delete(temp.random);
  }
}

o.O

[Tolnaftate2004]

Just make a copy and delete in a random order until you have 2 or 7 or whatever.

how would that sort an array?

It looked to me that all you were doing was taking select pieces from an array - and wanted them to retain their order.

Use

object.insert(index, value);

[Twizt3d]

Yes, I could use that but the second array is shorter then the original array(the order to sort the second array)
