[Action Script 3] hitTestObject is not a function

[levsingh]

hey guys just trying to make simple game in flash where this character runs and collects coins and then the coin count increases. this was working fine when i was dealing with just one coin and then i tried to do it with arrays and this error.

is there any other way to do it? i am new to as3 just doing it for 2 weeks. thanks

import flash.events.KeyboardEvent;


var char:mario = new mario();


addChild(char);


char.x = 300;


char.y = 720;


var money:coin = new coin();


var Coin:Array = new Array(money,money,money,money,money);


addChild(Coin[2]);


trace(Coin[2]);


for(var b:int = 0; b<5; b++)


{

addChild(Coin[b]);

Coin[b].x = 300;

Coin[b].y = 100*b;


}


stage.addEventListener(KeyboardEvent.KEY_DOWN,movement);



var a:int;

function movement(e:KeyboardEvent)

{

if(e.keyCode == 38) 

{

char.y -= 5;

}


if(e.keyCode == 40) 

{

char.y += 5;

}


if(e.keyCode == 37) 

{

char.x -= 5;

}


if(e.keyCode == 39) 

{

char.x += 5;

}


if(Coin.hitTestObject(char))

{


Coin[b].y = -5000;

a++;


}

trace("coins= " + a);

}

Instead of

var money:coin = new coin();var Coin:Array = new Array(money,money,money,money,money);

Try

var Coin:Array = new Array(new coin(),new coin(),new coin(),new coin(),new coin());

To make sure the problem isn't because they all reference the same coin object.

 

edit: Also, just noticed that you mentioned the "hitTestObject is not a function" error. I'm not really sure, but according to the documentation of hitTestObject it requires a DisplayObject type as a parameter. Does your class mario implement DisplayObject? Also, are you sure you can use it on an Array, or do you have to use it on items in the array?
