Scripting

1

i was going through some of the tutorials, most recently the “How to Fire” Game Tutorial (http://www.kirupa.com/developer/mx/fire.htm) and i have a few quick questions.

1 - What does _root refer to? Is it the object that is the code is linked too?

2 - They use _root.fire but I didnt see it defined anywhere so are there no variable declarations in Flash? Can you just make up whatever variables you want?

Which brings me to my 3rd question, which is a little longer. Is there a common set of methods and members that symbols have (ie: x coordinate and y coordinate) and what are they?

4 - In what circumstances would anyone include :egg: in a post?

  1. _root refers to the main stage, where everything goes.

  2. yes, unlike other programming languages, you do not have to declare variables in actionscript.

  3. for every symbol, there are several properties you can access and modify. all these properties begin with an underscore, for example, the x coordinate of “movie1” would be movie1._x; same for y. there’s also x and y scale, width and height, alpha, visibility (_visible), and some others.

  4. totally up to you, man. your call.

  1. _root refers to the main timeline in the hierarchy, or the very first timeline of your movie.

  2. You can declare variables, or you can just dynamically create them. Here is a tutorial on the variable scope in Flash MX http://www.kirupa.com/developer/actionscript/tricks/scope.asp

  3. Yes there is a common set, open up Flash MX, open the actions panel, in there you will see a “+” icon towards the top. Click on that and go to “Properties”, these are all the properties you can use associated with movie clips. Check out the other sections while your at it. Also on the left there should be a pull-out menu of the entire index of actions you can use. You can find full descriptions of most actionscript actions via the AS Reference in Flash MX… go to Window/Reference to open that panel and select the action from the left to see what it does and how it is used.
