Remove duplicate movieclips problem

i have shooter game duplicate bullet holes in wall.  works nicely though have use version: flash player 6 code work.  here simple code:

 

hit1.onpress=function(){

     i++;

     _root.bullet.duplicatemovieclip("bulletnew", i);

}

 

i have reset button use remove duplicate "bulletnew" movieclips @ once.  have far removes 1 duplicate @ time:

 

reset_mc.onrelease=function(){

     removemovieclip("bulletnew");

}

 

please clear instructions because have never grasped well.

 

thanks.

to publish later fp versions, initialize variables (like i) , check upper/lower case of code.

 

 

var i:number=0;
var tl:movieclip=this;

 

hit1.onpress=function(){

     i++;

     _root.bullet.duplicatemovieclip("bulletnew"+i, i);

}

 

 

 

reset_mc.onrelease=function(){

   for(var j:number=0;j<i;j++){

if(tl["bulletnew"+i]){

tl["bulletnew"+i].removemovieclip();

}

}

}

 

 

 

 

p.s.  if that's place create bullet holes, can make code more efficient looping through movieclips exist.  example:

 

var i:number=0;

var bulletnewa:array=[];

hit1.onpress=function(){

bulletnewa.push(_root.bullet.duplicatemovieclip("whatever",i));

}

reset_mc.onrelease=function(){

for(var j:number=bulletnewa.length-1;j>=0;j--){

var mc:movieclip=bulletnewa.splice(j,1)[0];

mc.removemovieclip();

}

}
