Error #1010: A term is undefined and has no properties. when it is not even on the stage

this error cant explain myself why trigger, because doesnt trigger every time - when shoot 1st or last ship of array , somehow changes , doesnt splice or that.

 

 

so have doships function:

 

function doships() {           (var i:int = shiparray.length - 1; >= 0; i--) {                     shiparray[i].movedown() //what code in ship , ship2 class -> only: this.y += 3                     (var bcount= _bulletsarray.length-1; bcount >= 0; bcount--) {                               //if bullet touching ship                                          if (shiparray[i].hittestobject(_bulletsarray[bcount])) {                                         //if here means there`s collision                                                    removechild(_bulletsarray[bcount]);                                         _bulletsarray.splice(bcount,1);                                         removechild(shiparray[i]);                                         shiparray.splice(i,1);                               }                     }           } }  

 

 

when debug fla error comes from

 

 @ arrayofships_newg_withturret_fla::maintimeline/doships()[arrayofships_newg_withturret_fla.maintimeline::frame1:100] 

 

 

line 100

 

if (shiparray[i].hittestobject(_bulletsarray[bcount])) { 

 

 

before there player on stage shoots bullets

//handling bullets function dobullets(){           //make loop iterate all  _bulletsarray on screen           (var bcount:int = _bulletsarray.length-1; bcount>=0; bcount--) {                     //make bullets move                     _bulletsarray[bcount].y -=20;                     //if bullet beyond screen remove stage , array                     if(_bulletsarray[bcount].y < 0) {                               removechild(_bulletsarray[bcount])                               _bulletsarray.splice(bcount,1);                     }           } }  

 

 

 

function move player in x coordinate.

and function positions ships,but not important because dont think have error.

 

i can show code of fla if going somehow solve this.

you splicing _bulletsarray, still looping through it.  maybe use while?
