tile=[emptyTile,tile1,tile2,tile3,tile4,tile5,tile6,tile7,tile8,tile9,tile10,tile11,tile12,tile13,tile14,tile15];
	puzzle =new FifteenPuzzle();	
	var tileNumber=0;
	puzzle.Randomize(1,true);
	for(var i=0; i<4;i++){
		for(var j=0; j<4; j++){
			var tilePosition=puzzle.getTile(i,j);
			Debug.Log("***************************************************"+i+","+j);
			tile[tilePosition].SendMessage("InitPosition",cubePositions[i][j],SendMessageOptions.DontRequireReceiver);
			
			tile[tilePosition].SendMessage("SetTilePosition",new Vector2(i,j),SendMessageOptions.DontRequireReceiver);
			
		}	
	}

above code is working fine in my system but if I tried to install if in ipad getting below exception, what may be the problem?

I am just guessing, since I am not an expert but…
SendMessage is using reflection. See Unity Manual > Getting Started with iOS Development > Optimizing Performance in iOS. > Optimizing iOS Players build Size

for a description of the stripping options in the player settings. Try disabling stripping to see if the error goes away.

If anyone wants to correct me, feel free. I won’t be offended. LOL

Most likely you are hitting some limitations Unity Script dynamic functionality. I would recommend to turn strict typing for your script on.
You can do this by adding following line at the very top of your script file:
#pragma strict

This might give you several compile time errors, but after fixing them you will get improved code compatibility with AOT.

Thanks for your reply mantasp.

I found the exception where I am getting exactly. Here send message is not the problem, I should not use dynamic type casting for the arrays.
I should specify the “tile[tilePosition]” type before going to use it.
