Hi,
i have an external file that contains a multidimensional array. it looks something like this:
var map = [
[2,2,5,2,1,2,2],
[2,0,2,2,3,2,2],
[2,2,2,2,2,0,0]
]
I try to load the file into flash by writing:
Externaldata= new LoadVars();
Externaldata.load("solarintensity.as");
Externaldata.onLoad= function(success){
if (success){
trace(Externaldata);
SolarArray= new Array();
SolarArray = Externaldata;
trace ("first number: " + SolarArray.map[1][1]);
this is what I get:var%20map%20=%20%5B%0D%0A%5B2%2C2%2C2 .....
and for the second trace Igot:first number : undefined
how exactly can I read the file in as an array and be able to use it the way it is in flash? or how do I access the data?

Hope someone can help me!!! THANKS SO MUCH!!!!

in other words: don't use the Enter/Space in the external files
these are a unicode characters

I changed my external file, didn't use enter/ space but still getting the same thing:

my external looks like this:
map=[[2,2,2,2,2,2],[3,5,2,2,2,2],[2,1,4,2,4,1],[2,2,2,2,2,2]]

and this is what I get when I try to read it into flash. What exactly should I do?

map=%5B%5B2%2C2%2C2%2C2%2C2%2C2%5D%2C%5B3%2C5%2C2% 2C2%2C2%2C2%5D%2C%5B2%2C1%2C4%2C2%2C4%2C1%5D%2C%5B 2%2C2%2C2%2C2%2C2%2C2%5D%5D&onLoad=%5Btype%20

PLS HELP!! THANK YOU SO MUCH!

Howdy... ;)

If you are loading the text file, whether it is *.AS file or *.TXT file, via LoadVars() object, Flash will ONLY read the data as STRING...

So, in other words, your text filemap=[[2,2,2,2,2,2],[3,5,2,2,2,2],[2,1,4,2,4,1],[2,2,2,2,2,2]]can be accessed in Flash as bunch of strings but it won't be recognized as a form of an array...

So, what you gotta do is to use split() function once the data is loaded into the Flash...

Read these threads for more information on how to use split() function to and populate the array with that data...
