1) When you click on the "Generate" button a 15x21 board of Tile symbols is created, with top-left corner at (10,10). Initially all tiles should be blank.

i need to somehow get that done.

here is my code so far, i have a lot of graphics, movie clips and a button relating to the script, although right now they are not important.

var ghosts:Array = new Array();

var timers:Array = new Array();

//======== ghosts and ghost behaviour =================//

var ghostHoriz=1;

for (var row = 0; row < 4; row++) {

          var g = new Ghost();

          var t:Timer=new Timer(400);

          g.timer=t;

          timers[row]=t;

          g.horiz=ghostHoriz;

          ghostHoriz*=-1;

          if (row==0||row==1) {

                    g.vert=1;

          }

          else {

                    g.vert=-1;

          }

          t.addEventListener(TimerEvent.TIMER, moveGhost);

          ghosts[row]=g;

          g.visible=false;

          addChild(g);

}

var ghostIndex=0;

function moveGhost(evt:TimerEvent) {

          var t=evt.currentTarget;

          var k=timers.indexOf(t);

          var g=ghosts as Ghost;

          if (g.visible) {

                    var r=g.row;

                    var c=g.col;

                    with (g) {

                              if (Math.random()<0.5) {

                                        if (((horiz > 0 && (c+horiz)<21)||(horiz < 0 && (c+horiz)>=0)) && (map[c+horiz]==0)) {

                                                  col+=horiz;

                                                  x+=horiz*20;

                                                  map[c+horiz]=2;

                                                  map=0;

                                        }

                                        else {

                                                  horiz*=-1;

                                        }

                              }

                              else {

                                        if ( (( vert > 0 && (r+vert)<15)||( vert < 0 &&(r+vert)>= 0)) && (map[r+vert]==0)) {

                                                  row+=vert;

                                                  y+=vert*20;

                                                  map[r+vert]=2;

                                                  map=0;

                                        }

                                        else {

                                                  vert*=-1;

                                        }

                              }

                    }

          }

}

// ================= Button behaviour ========== //

generate_btn.addEventListener(MouseEvent.CLICK, generate);

function generate(m:MouseEvent = null) {

          initMap();

          ghostIndex=0;

// other stuff

          displayMap();

}

var map:Array = new Array();

var tiles:Array = new Array();

function initMap(){

 

}

function displayMap() {

          for (var row = 0; row < 15; row++) {

                    for (var col = 0; col < 21; col++) {

                              var test=map[row][col];

                              tiles[row][col].x=10+col*20;

                              tiles[row][col].y=10+row*20;

                              switch (test) {

                                        case 2 :

                                                  g=ghosts[ghostIndex];

                                                  g.x=10+col*20;

                                                  g.y=10+row*20;

                                                  g.row=row;

                                                  g.col=col;

                                                  if (row==0) {

                                                            g.vert=1;

                                                  }

                                                  else {

                                                            g.vert=-1;

                                                  }

                                                  g.visible=true;

                                                  g.timer.start();

                                                  ghostIndex++;

                                                  break;

                              }

                    }

          }

}

bit long 😕😕

anyway when I basically need it so when you press generate it comes up with a random, how do i put this....it comes up with a random pacman sort of design. And everytime generate is clicked it changes, anyone know anything?

also note, with the code up there, if I do click generate i get this error...

Fonts should be embedded for any text that may be edited at runtime, other than text with the "Use Device Fonts" setting. Use the Text > Font Embedding command to embed fonts.

TypeError: Error #1010: A term is undefined and has no properties.

thanks in advance.

This code is almost the same as a previous example but it randomizes tiles in the array - watch labels.

If you populate array with your tiles - you can be in business soon as far as the grid generation goes.

import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFormat;
var tiles:Array;
var rows:int = 15;
var cols:int = 21;
getTiles();
drawGrid();
function getTiles():void
{
          tiles = [];
          var numTiles:int = rows * cols;
          for (var i:int = 0; i < numTiles; i++)
          {
                    tiles.push(drawTile(i));
          }
          shuffle(tiles);
}
function drawGrid():void
{
          for (var i:int = 0; i < tiles.length; i++)
          {
                    var t:Sprite = tiles;
                    t.x = t.width * int(i / rows);
                    t.y = t.height * (i % rows);
                    addChild(t);
          }
}
function drawTile(index:int):Sprite
{
          var tileSide:int = 40;
          var color:uint = 0xffffff * Math.random();
          var tile:Sprite = new Sprite();
          tile.graphics.beginFill(color);
          tile.graphics.drawRect(0, 0, tileSide, tileSide);
  
          var label:TextField = new TextField();
          label.defaultTextFormat = new TextFormat("Arial", 11, 0xffffff - color, "bold");
          label.autoSize = "left";
          label.text = String(index);
          label.x = label.y = 4;
          tile.addChild(label);
          return tile;
}
function shuffle(a:Array):void
{
          for (var i:int = a.length - 1; i >= 0; i--)
          {
                    var r:int = Math.floor(Math.random() * (i + 1));
                    var t:Object = a;
                    a = a;
                    a = t;
          }
}

Here is how to do that from previously populated array - watch tiles:Array (still just a concept):

import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFormat;
var tiles:Array;
var rows:int = 15;
var cols:int = 21;
getTiles();
drawGrid();
function getTiles():void
{
          tiles = [];
          var numTiles:int = rows * cols;
          for (var i:int = 0; i < numTiles; i++)
          {
                    tiles.push(drawTile(i));
          }
}
function drawGrid():void
{
          for (var i:int = 0; i < tiles.length; i++)
          {
                    var t:Sprite = tiles;
                    t.x = t.width * int(i / rows);
                    t.y = t.height * (i % rows);
                    addChild(t);
          }
}
function drawTile(index:int):Sprite
{
          var tileSide:int = 40;
          var color:uint = 0xffffff * Math.random();
          var tile:Sprite = new Sprite();
          tile.graphics.beginFill(color);
          tile.graphics.drawRect(0, 0, tileSide, tileSide);
  
          var label:TextField = new TextField();
          label.defaultTextFormat = new TextFormat("Arial", 11, 0xffffff - color, "bold");
          label.autoSize = "left";
          label.text = String(index);
          label.x = label.y = 4;
          tile.addChild(label);
          return tile;
}

Here is a conceptual blueprint on how to generate grid. Just paste code on timeline.

import flash.display.Sprite;
drawGrid();
function drawGrid():void
{
          var rows:int = 15;
          var cols:int = 21;
          var numTiles:int = rows * cols;
          for (var i:int = 0; i < numTiles; i++)
          {
                    var t:Sprite = tile;
                    t.x = t.width * int(i / rows);
                    t.y = t.height * (i % rows);
                    addChild(t);
          }
}
function get tile():Sprite
{
          var t:Sprite = new Sprite();
          t.graphics.beginFill(0xffffff * Math.random());
          t.graphics.drawRect(0, 0, 30, 30);
          return t;
}

erm...i figured out where to past it, but once that happens the whole thing goes multicoloured and checkered....which is not really what I wanted.

you have a 15x21 grid and 4 ghosts are to be assigned to 4 grid tiles?
