Flash CS3 Tutorial – ActionScript 3 Depths
Flash Tutorial 13 Comments »One of the many things that have changed in ActionScript 3 has been the way that Flash handles depths, or the stacking order of objects on the stage. In ActionScript 2, there was a practically unlimited number of depths into which you could place an object. These depths determine what objects appear in front of other objects. An object with a depth of 100, for example, would cover up an object with a depth of 50. But in ActionScript 2, these depths didn't have to be consecutive. In other words, if you only had 2 objects on the stage, you could very well set one of them to a depth of zero and set the other one to a depth of 1000.


There is very little that will push users away quicker than a bulky Flash website with no preloader. Without a preloader, your users will have nothing to look at but a blank screen until your Flash file has fully loaded. For users with a speedy broadband connection, this may not be much of an issue (depending on the size of your file), but for people with sluggish connections, it's imperative that you give them some kind of indication that everything is loading properly.
