[AS3] health system

[Lav]

hello,

I'm trying to make a board game in flash and i want to use a sort of health system in my game, for example, if a player gets to a certain square, he will lose 1 hp but if he uses his hp-kit, everything will be repaired.

i first declared a globar var hp and made it 3, I then created 3 red squares next to eachother in a function

for(var i:int = 0; i<hp; i++)
{
this.graphics.beginFill(0xFF0000);
this.graphics.drawRect((kaderAvatar.x - 50)+i*15, 15, 15, 15);
this.graphics.endFill();
}


it works this far, but when i try to check what kind of square the player is on, and if it's the one where i need to reduce hp i simply use hp--; (the code to check what square its on works, i checked it with trace so no problem there)


now i'm a bit stuck where to go from here to make it actually work. I tried to make a different function that returns hp but i can't seem to make it work, anyone can help me?
And sorry if my english isn't that good

Do you really want the number of squares to match the hitpoints? Anyway, what is your question? How to return your hitpoints?

public function getHP():Number {
return hp;
}

if my activePlayer (my game has 2 players) hits a certain square, for example square14, then i want 1 (of the 3) hpbox to disappear so i thought to do it with just hp--;

this is how i check how i check if it's square 14 and that code works fine with other things

if(activePlayer.goalPosition == 14)
{
hp--;
trace(hp);
}


when i trace it it tells me that hp = 2 so the value of hp does change but i need to repaint with the new hp value so it should only paint 2 boxes.
But i don't know how to repaint it, i tried recalling the function and using Event.ENTER_FRAME.
pardon me if this seems like a trivial question, i'm still very new to AS3

I don't know AS3, but I might be able to help you. In the code that draws the squares, add:
this.graphics.clear();
before your drawing commands.

thanks for the suggestion, it didn't really work but the deadline of the project has already passed so i did it without the health system. I'm still curious how i could have solved it tho, still quite a mystery to me :p

If, instead of a global variable you made a health class and made a static reference to an instance of that class, then in this health class you could make public getters and setters for the hp value:

protected var _hp:int;

public function get hp():int {
return _hp;
}

public function set hp(newVal:int):void {
if (newVal!=_hp) {
_hp=newVal;
graphics.clear();
for(var i:int = 0; i<hp; i++)
{
...draw square
}
}
}
