Hi All,
I would really appreciate some help.
I have created a drag and drop matching activity and the way it is coded presently, I have given the cards that are dragged the instance names card1, card2, card3…and so forth, and I have named their drop targets zone1, zone2, zone3…and so forth. The code then verifies that the match is correct if card1 hitTest is zone1 and so forth.
This has worked in the past, however in my latest project there are duplicate correct answers.
I will give an example.
Suppose there is a bowl of fruit and the user is asked how many pieces of each type of fruit are in the bowl. They then drag a card with a number to the drop zone by the type of fruit.
If there are 2 oranges and 2 apples the user should be correct no matter which card with a 2 they drag to either piece of fruit.
The way I currently have it coded they have to place the 2 card with the instance name of card1 on zone1 and the 2 card with the instance name of card3 on zone3.
I would really appreciate any help I can get with this.
Here is the code I am currently using:
// Function when card is pressed
function drag(card:MovieClip):Void{
card.startDrag(); // Start dragging the movie clip
card.swapDepths(swapper); // Keep the card above all other things on the stage
}
// function after the card is released
function drop(card:MovieClip):Void{
card.stopDrag(); // stop dragging of card
card.swapDepths(swapper); // put card back to its starting level
checkZoneHit(card); // check to see if the card hit a zone
}
// function to see if the card hit a zone
function checkZoneHit(card:MovieClip):Void{
for(var i:Number = 1; i <= _root.num_cards; i++){
var zone:MovieClip = this[“zone”+i]; // get the zones in order
if(card.hitTest(zone)){
checkCardHit(card, zone); // see if card has hit another card
return; // exit function
}
}
// No hits
resetCard(card); // reset the card
}
function checkCardHit(card:MovieClip, zone:MovieClip):Void{
for(var i:Number = 1; i <= _root.num_cards; i++){
var checker:MovieClip = this[“card”+i]; // get the cards in order
if(card != checker){ // make sure you aren’t checking the same card
if(card.hitTest(checker)){
resetCard(card); // reset the card
return; // exit function
}
}
}
// No cards hit
setCard(card, zone); // set the card to the zone
}
// function to set a cards coords to a zones coords
function setCard(card:MovieClip, zone:MovieClip):Void{
card._x = zone._x; // set x coord
