Hey guys,

I am learning (try to, haha) about JavaScript + Construct and a tried a simple function but I think I made it wrong.

My function set opacity of object:
function setOpacity(obj, opacity) { obj.opacity = opacity / 100; }

And I call the function every the Family "enemies" is created:

setOpacity(enemies, 50);

It depends what enemies is in your code. If it's a family it won't work, because opacity is a property of object instances, not entire families.

I would advise taking the Learn JavaScript in Construct tutorial series, and in particular part 11 which covers this area.
