ActionScript 3.0 :: Using MovieClip Inside Each Other For Different Animations

I'm making a game, and I made a class for the player character, as it is a platformer the character has different animations for different actions (jump, walk, etc...), I create a movieclip for each animation put them all inside a movieclip and tryed to use an array to set the visibility of each movieclip true or false. The problem is I can't reach the moviclips inside the each other.

The code I tried was these
Code: Select allprivate var charClips:Array = new Array();
charClips.push(char.walk, char.jump, char.down, char.stand);
private function setVisible(clip:MovieClip){
for (var i:int=0; i<charClips.length;i++){
if(clip = charClips[i]){
clip.visible = true;
}else{
clip.visible = false;
}}}
And for each action I call setVisible(char.walk).
