looping through all children

// Moves all transform children 10 units upwards!
for (var child : Transform in transform) {
child.Translate(0, 1, 0);
}

I came across this code in the scripting overview, and I was wondering what this does exactly. The variable is of type Transform, but what is the "in transform" doing?

As simply as I can put it - Transform is a type which can be enumerated over (kinda like looped over)

Any type which can be enumerated over lets you use the for(blah in enumerator) syntax - another example would be:

for (var str : String in stringArray){}

Transform (Or any class which is enumerable) has to define how it needs to be iterated through, in the case of Transform, it loops through its children

Hey Mike, How would one go about finding this in the documentation? In other words, if I go to Transform, will I see how it is enumerated?
