Switching a tile position in random

[playh5]

Hi, I have this problem which makes my head scratching for hours, so I added a sprite by a for loop so I have 4 tiles in row and 4 tiles in column. Then I store the positions in an array with elements as phaser points. This way I can record the exact original position for later use.

 

Then I want the tiles to randomly select a new point  in random but not its original point. I tried so many times, but I am stuck in having two tiles at the same point and sometimes I made a looping that does not position the tiles in random.

 

Any help would be greatly appreciated. Thanks in advance.

I am not familiar with phaser, but it would work something like this

//starting locationvar orig_x = 2;var orig_y = 2;//random new location 0-3. Arrays start at 0 so 4 len/widevar new_x = Math.floor(Math.random() * 3);var new_y = Math.floor(Math.random() * 3); //Keep on looping until the new x isn't 2 and new y isn't 2while(orig_x <> new_x && orig_y <> new_y){new_x = Math.floor(Math.random() * 3);new_y = Math.floor(Math.random() * 3);}

I am assuming your positions are grid positions. If your poition is mouse co-ords. It will work a little different. Either way the same concept will work.

Map[x][y]

Thanks!  In as3 I did it like this although there is always a tile that is going to its original x and y position.

import flash.geom.Point;var sArray = [a,b,c,d,e,f,g,h];var pointList = [];var newPointList = [];// store mc original positions into arrayfor(var i = 0;i < sArray.length; i++){	var point:Point = new Point(sArray[i].x,sArray[i].y);	pointList.push(point);}trace(pointList);while(pointList.length > 0){	var r:int = Math.floor(Math.random()*pointList.length);	newPointList.push(pointList[r]);	pointList.splice(r,1);}for(var n = 0;n < sArray.length; n++){	var newPoint:Point = newPointList[n];	sArray[n].x = newPoint.x;	sArray[n].y = newPoint.y;}
