As2 Hittest And Variable Help

[FortressRubbish]

Okay, so I'm developing my first solo game.

I've got code so that you have 10 lives.

but while the enemy is touching you you lose them equal to the framerate.

onClipEvent(enterFrame){
if (_root.player.hitTest(this)){
_root.lives --;
}
}

how do I make it so you can only lose one life per hit?

Also, I've been trying to code temporary invulnerability when the player is hurt, so they have time to recover. I have no idea how to implement this haha. Can anyone shine some light in this direction on that? I'd REALLY appreciate any help I can get, as I'm very new to all this coding business.

Here's a demo of the game if you'd like to play it to get a feel for what I'm talking about.

onClipEvent(load){
i=0
}
onClipEvent(enterFrame){
if (_root.player.hitTest(this)){
if(i<1){
_root.lives --;
i++
} else {
i=0
}
}
}

On MC:

onClipEvent(enterFrame){
	if(_root.player.hitTest(this)){
		_root.GOTHIT();	
	}
}

On main timeline:

invulnerable=0;			//BOOLEAN
invTime=1.5;				//NUMBER OF SECONDS' INVULNERABILITY

function GOTHIT(){
	if(!invulnerable){
		invulnerable=1;
		lives--;
		clearTimeout(fff);
		fff=setTimeout(function(){invulnerable=0;},invTime*1000);
	}
}
