Question

So, I need to fill a bi-dimensional array in JavaScript and I’m doing it the following way:

var i = 0, j = 0;
for (i = 0; i < roomWidth / tileWidth; i += 1) {
     roomBuffer[i] = [];
}
for (i = 0; roomWidth / tileWidth; i += 1) {
     for (j = 0; j < roomHeight / tileHeight; j += 1) {
          roomBuffer[i][j] = 1;
     }
}
alert("Hello world");

The problem is that it not only doesn’t work but any code that comes after it, it’s not executed. In this case the alert("Hello world");. What am I doing wrong guys?

change

for (i = 0; roomWidth / tileWidth; i += 1) {

to

for (i = 0; i < roomWidth / tileWidth; i += 1) {
