Re: [Flashcoders] bidimensional array in as
maybe a silly question, but here i go anyway: how would you write something like this in actionscript: int matrix[3][3]; for(i=0;i<3;i++) for(j=0;j<3;j++) matrix[i][j]=0; i've done something like this in my code, mtasc doesnt complained, but the program doesnt work, and i have a feeling that something wrong. This has been answered twice, but without explaining *why* it works this way. The fact is, there are no multidimensional arrays in AS (ECMA). What you have instead is an array of arrays. As such, the child arrays must be declared before they can have elements assigned to them. ryanm ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

Yea, I'm a dufus. I think I was in AS3 mode when i posted that - then
again, I didn't test it either...
i'll be quiet now. :)

Re: [Flashcoders] bidimensional array in as
int matrix[3][3];
for(i=0;i<3;i++)
for(j=0;j<3;j++)
matrix[i][j]=0;
You have to create the initial array and then create any sub array. Kinda
like:
matrix = [];
for(i=0;i<3;i++) {
matrix[i] = [];
for(j=0;j<3;j++) {
matrix[i][j] = 0;
}
}
