Array Function Trouble
Posted in xn--kfs74mzzid01b.com edit by jane on January 7th, 2009
// a quick example of a map
// tile1 = ([1, 2, 3, "walk", 0.45, 10]);
// tile2 = ([4, 5, 6, "wall", 0.23, 70]);
// mymap = ([ ([tile1,tile1,tile2]),
// ([tile2,tile2,tile2]) ]);
var newMap:Boolean = true;
var map:Array;
function createMap(w, h, tile) {
var map:Array;
for (var i = 0; i < h; ++i) {
map.push(createRow(w, tile));
}
return map;
}
function createRow(w, tile) {
var row:Array;
for (var i = 0; i < w; ++i) {
row.push(tile);
}
return row;
}
function mapHandle(w, h, map, default_tile) {
var newmap:Array;
var mapW = map[0].length;
var mapH = map.length;
if (newMap) {
newmap = createMap(w, h, default_tile);
return newmap;
}
else {
if (w < mapW) {
for (var i = 0; i < mapH; ++i) {
for (var j = 0; j < (mapW - w); ++j) {
map[i].pop();
}
}
}
if (w > mapW) {
for (var i = 0; i < mapH; ++i) {
for (var j = 0; j < (w - mapW); ++j) {
map[i].push(default_tile);
}
}
}
if (h < mapH) {
for (var i = 0; i < (mapH - h); ++i) {
map.pop();
}
}
if (h > mapH) {
for (var i = 0; i < (h - mapH); ++i) {
map.push(createRow(w, default_tile));
}
}
}
}
.. when I try to do something like this:
var testTile = ([1,2,3,4,5]);
var testMap = createMap(10,10,testTile);
trace(testMap);
I end up with undefined instead of my 10x10 3D array.
I'm working on http://www.student.cs.uwaterloo.ca/~bbobnis/ if that's any aid at all.
I want to get an array instead of undefined. What am I doing wrong?
Thank you in advance,

//you have:
var title:Array = ([a,b,c]);
//should just be
var title:Array = [a,b,c];
// unless I'm missing something here
var map:Array = Array();
function createMap(w, h, tile) {
var map:Array = Array();
for (var i = 0; i < h; ++i) {
map.push(createRow(w, tile));
}
return map;
}
function createRow(w, tile) {
var row:Array = Array();
for (var i = 0; i < w; ++i) {
row.push(tile);
}
return row;
}
function mapHandle(w, h, map, default_tile) {
var newmap:Array = Array();
var mapW = map[0].length;
var mapH = map.length;
if (newMap) {
newmap = createMap(w, h, default_tile);
return newmap;
}
else {
if (w < mapW) {
for (var i = 0; i < mapH; ++i) {
for (var j = 0; j < (mapW - w); ++j) {
map[i].pop();
}
}
}
if (w > mapW) {
for (var i = 0; i < mapH; ++i) {
for (var j = 0; j < (w - mapW); ++j) {
map[i].push(default_tile);
}
}
}
if (h < mapH) {
for (var i = 0; i < (mapH - h); ++i) {
map.pop();
}
}
if (h > mapH) {
for (var i = 0; i < (h - mapH); ++i) {
map.push(createRow(w, default_tile));
}
}
}
}
The following test cases work now:
var testTile:Array = Array(1,2,3);
var testMap:Array = createMap(1,2,testTile);
trace(testMap);
trace(testMap[1][0][2]);
Thought I'd post this in case anyone else was having similar problems.
I'll bug this forum when I get stumped, again,
