Remove Object from Array

Hello,

Following Problem:

I want to remove a child from an Array. I removed all refrences, the child and set it =null. I also used weak references where i couldnt remove eventlistener. Anyways the Child is still in the Array.

for(var i = 0;i < fliesArray.length;i++){

  removeChild(fliesArray[1]);

  fliesArray[1] = null;

  TweenMax.killTweensOf(fliesArray[0]);

  removeChild(fliesArray[0]);

  fliesArray[0] = null;

I have this in my "end game" function

also I thought the Arrays in AS3 dynamicly closes the gap if an Object is deletet.

Example: Object with index 25 is deletet, object with index 26 gets index 25, index 27 gets 26 etc. pp.

is that correct?

Thanks!
