[FIXED] How can I get an index of a two dimensional array?

Issue

I have a two-dimensional array like this:

(0|0),(0|1),(0|2)
(1|0),(1|1),(1|2)

I know the width and height of the array. I want to calculate the indexes as a single number like this:

0,1,2
3,4,5

How do I do this?

Solution

Looks like index = row * width + column to me.
