array_length_2d(array, n);
| Argument | Description |
|---|---|
| array | The array to check. |
| n | The entry of the array to get the length of. |
Returns: Real
With this function you can get the length (number of entries) of a the second dimension of an array. You supply the entry number
for the first dimension and the function will return the number of second dimension entries that the array has (to find the length
of the first dimension use the function array_height_2D). The function will return
0 if the variable given is not an array or 1 if the variable is a 1D array (as there is still 1 row).
for (var i = array_height_2d(a) - 1; i > -1; i--;)
{
for (var j = array_length_2d(a, i) - 1; j > -1; j--;)
{
a[i, j] = -1;
}
}
The above code will loop through a 2D array and set each entry to -1.
