Declare an array of strings that will later be retrieved using the Push Data action with a dictionary lookup. There can be a maximum of 65534 strings. The visibility of a dictionary is within its DoAction or other similar block of actions. Note that you should have only one Declare Dictionary. The dictionary is visible from everywhere in the DoAction. In other words, you can access it from functions1, With blocks, try/catch/finally blocks, etc.

When multiple Declare Dictionary actions are used, ...

• 1. Declare Function and Declare Function 2 both accept accesses to Declare Dictionary.

Pop one integer, use it as a multi-byte string character code and push the newly created string on the stack.

The integer can be any number from 0 to 65535, although many codes are not valid characters.

For more information about valid characters, please, check out the Unicode Consortium.

struct swf_doabc {
	swf_tag			f_tag;		/* 72 or 82 */

	}
	swf_action3		f_action_record[variable];
};

^*the version specified here is the version in which the tags appeared—however, actions of higher versions can be used with older version tags and thus this version doesn't indicate the version of all the actions used in this tag

The DoABC and DoABCDefine are available since version 9. These are similar to the old DoAction and DoInitAction, yet the actions use a way different declaration scheme and they include flags and a name. This new scheme helps greatly in simplifying the definitions of ECMAScript classes and accelerate the access to the code tremendously.

Note that the ...

struct swf_metadata {
	swf_tag			f_tag;		/* 77 */
	string			f_metadata;
};

The Metadata tag is used to describe the SWF movie in a robot readable form. It will be used by search engines to index your Flash movies.

The f_metadata string is an XML buffer defined using the RDF definition compliant with the XMP specification. You can find more information on the W3C and other websites:

RDF Primer
RDF Specification
Dublin Core

Note that this description can describe everything, from the entire movie to each single line of code in your action scripts.

The string must be UTF-8 encoded.

Moved the monolithic documentation to a multi-page hierarchical document that includes everything we had before plus many links, many terms attached to all pages (tags, English words.) And revision of most of the text for better English and clarification in some places.

Strengthen the formatting with CCK fields so all declarations look alike.

Broken up the actions from one large table to a set of pages.

Started work on the Load() feature of the SSWF library. This helped fixing several small mistakes in the documentation.

Edges are used to define a shape vector based and also coordinates where images need to be drawn. The edges are always coordinates from where ever your last point was to where ever you want the next point to be (a little like a turtle in LOGO).

struct swf_condition {
	unsigned short		f_condition_length;
	unsigned		f_condition_key : 7;
	unsigned		f_condition_menu_leave : 1;
	unsigned		f_condition_menu_enter : 1;
	unsigned		f_condition_pointer_release_ouside : 1;
	unsigned		f_condition_pointer_drag_enter : 1;
	unsigned		f_condition_pointer_drag_leave : 1;
	unsigned		f_condition_pointer_release_inside : 1;
	unsigned		f_condition_pointer_push : 1;
	unsigned		f_condition_pointer_leave : 1;
	unsigned		f_condition_pointer_enter : 1;
	swf_action		f_action_record[variable];
};

A condition is defined in a DefineButton2 tag. It is a record of conditions. The record terminates when the size of the current (i.e. last) condition is zero. The length of that condition can be deduced from the total size of the tag minus the offset where the condition starts. Conditions are similar to events.

The f_key field represents a key code since version 4. The following table gives the code equivalence. Note that 0 means no key.

The pages defined below include all the actions defined in Flash.

Different actions are supported in different version, so please, look at the version when attempting to use that action.

Some actions have been deprecated and should not be used in newer version of Flash (mainly the untyped operators.)

There are two schemes supported in Flash 9 and over: ActionScript 2 and 3 (also referenced as AS2 and AS3.)

Since Flash version 9, actions can be saved in a new format named abcFormat by the Tamarin project from the Mozilla organization.

The code itself (action script) is the same, but the structure of an swf_action3 holds object oriented information about classes, methods and such in a really clean way (really! in comparison to the old way, that's dead clean!).

At this time, the swf_action3 structure is documented in the abcFormat.html file.

I will duplicate and test the structures at a later time.

A filter defines how to transform the objects it is attached to. The first byte is the filter type. The data following depend on the type. Because each filter is much different, they are defined in separate structures. You can attach a filter to an object using an ActionScript or the PlaceObject3 tag.

The following describes the different filters available since version 8.
