Remove element from array

Hi !

I have an array used to track shots fired from a cannon, and when they hit the ground they are removed.

I would like to know what is the most efficient way of finding and removing a certain element from an array. I heard that using pop() instead of splice() was faster, is it ?

Also, the big question I have is that the only way I see of actually finding the element in the array is using

Code:

---

for(i=0;i<array.length;i++){
  if(array[i] == movieClipToRemove){
  //i == movieClip index in the array
  }
}

---

Then I would use either splice() or pop() to remove it from the array before deleting the MC. Is there a better way than scanning through the whole array comparing each element to the triggering MC ?

Thank you guys :)

splice is the way to go to remove a specific index....pop always removes the last index in the array.

But you can use pop to remove specific element by using

array[index] = array.pop()

And it might just be faster considering it doesn't have to re-sort the whole array since only two elements are being changed. So I want to know which is faster, and also how to find that element in the array.
