Get the current movie timer in milliseconds and push it on the stack. The current movie is defined with the Set Target action.

This is equivalent to the number of frames that have been played so far.

This action is similar to Get Property of frames loaded.

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.

struct swf_doabc {
	swf_tag			f_tag;		/* 72 or 82 */
	if(f_tag == DoABC) {
		unsigned long	f_action_flags;
		string		f_action_name;
	}
	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_definebutton2 {
	swf_tag		f_tag;		/* 34 */
	unsigned short		f_button_id;
	unsigned		f_reserved : 7;
	unsigned		f_menu : 1;
	unsigned short		f_buttons_size;
	swf_button		f_buttons;
	swf_condition		f_conditions;
};

The DefineButton2 is very similar to the DefineButton tag. The list of actions was however changed in a list of actions to execute on a condition. Whenever an event occur, the plugin checks for that condition within all the buttons which can possibly catch that event at the time. For all the matches it finds, the corresponding actions are executed.

The SWF Reference by Alexis is part of the free SSWF project.

This documentation is intended for people who want to program a Flash player, editor, or some similar tool handling Flash data.

The project comes with a complete C++ library that is designed to greatly simplify the generation and loading of Flash files.

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).

The coordinates are often transformed with the use of a matrix. The matrix is similar to a transformation matrix in Postscript. It includes a set of scaling factors, rotation angles and translations.

When only the scaling factors are used (no rotation) then these are ratios as one would expect. If a rotation is also applied, then the scaling ratios will be affected accordingly.

};

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.

struct swf_event {
	char align;
	if(version >= 6) {
		unsigned	f_event_reserved : 13;
		if(version >= 7) {
			unsigned	f_event_construct : 1;
		}
		else {

	unsigned		f_event_enter_frame : 1;
	unsigned		f_event_onload : 1;
	unsigned long		f_event_length;
	swf_action		f_action_record[variable];
};

An event is defined in a PlaceObject2 tag. It is a record of events terminated with a set of zero flags. Events are similar to conditions.

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.
