swapping array elements

[blanius]

Decided not to continue this in the bitmap thread.....Still working occasionally on the video poker thing . Decided that having another array for the hand complicated some things and wasn't the way to go.....

I have a shuffled array of 52 movie clips each with a card graphic on it, a suit value and a value. I'm going to treat the first 5 cards as always being the "hand" so what I'm now trying to do is make a swap function but I'm not doing something right and cannot seem to make it work.....

code:

---

swap=function(i,j){

	

	i=j

	j=temp

	}

	//swap(test[0],test[1])

test=new Array(1,2,3,4)

txt1.text=test[0]

txt2.text=test[1]

---

didn't work nor did

code:

---

Array.prototype.swap=function(i,j){

	var temp=this[i]

	this[i]=this[j]

	this[j]=temp

	}

deck.swap(x,cardsDrawn)

That your first attempt doesn't work is logical since changing i and j variables within the function doesn't affect the parameters that were used to set these variables.

Your second attempt looks fine to me.
What exactly isn't working ?

The first one was me trying things. The second one is the one I was actually using. It does turn out to work... Here's the problem it turns out.

the assignment of the movieclips changed but not the way I had expected. for example a 2 of clubs is in deck[0] and I swap it with deck[5] now deck[5] is 2 of clubs and in the has swapped x,y position as well with deck[0] so now I've got to get the x and y and such to swap back...... I wonder if I should make it part of my swap function to somehow have them NOT swap paramaters.

[w.brants]

The coordinates also being swapped is logical since the only thing swapped are the movieclip references when it's an array of movieclips.

If you only want to swap some things, you could try something like this ...

Array.prototype.objectSwap = function(i0, i1, props){
 var i,p,t;
 props = props.split(',');
 t = new Object();
 for (i = 0; i < this.length; i++){
  p = props[i];
  t[p] = this[i0][p];
  this[i0][p] = this[i1][p];
 }
 for (i = 0; i < this.length; i++){
  p = props[i];
  this[i1][p] = t[p];
 }
}  
  
a = [{x:1,y:2,z:7},{x:3,y:4,z:8},{x:5,y:6,z:9}];

// swap properties x and z of item 0 with x and z of item 2
a.objectSwap(0,2,'x,z');

txt1.text = 'x:' + a[0].x + ' y:' + a[0].y + ' z:' + a[0].z;

Another option of course is to change the function to swap everything except the properties you specify.

kept it simple as I needed to move the new card to the drawpile to animate it anyway. It just confused me as it didn't LOOK like the cards were swapped. Think I have all the basic animation and card handling done now, all thats left to do is the hand evaluation and the clean up for the next hand. I have that pretty well mapped out so that could go quickly then I've got the basic game ready. I have a few ideas for extras to add but we'll see I'm growing weary of this already....

in case anyone is interested in looking over my shoulder here's what I have so far.

	m.lineStyle(2,0x9FFFCF,50,true,"normal","round","round")
	m.beginFill(0x9FFFCF,60)
	m.moveTo(x,y)
	m.lineTo(w,y)
