Question

What does the operator /= mean in action script? I have seen some easing functions using this:

var ts:Number=(t/=d)*t;

but have no clue what this t/=d mean.

Thanks in advance.

Answer 1

foo /= bar is a shorthand form of foo = foo / bar.

The return value from the foo /= bar operation is foo / bar

The expanded form of this code is:

var ts:Number = t;
ts = ts / d;
ts = ts * ts;
t = t / d;

A better way of writing that line would have been:

t /= d;
var ts:Number = t * t;
