#initclip
Availability
Flash Player 6.
Usage
#initclip order
Parameters
order
An integer that specifies the execution order of blocks of #initclip
code. This is an optional parameter.
Description
Action; indicates the start of a block of component initialization actions. When multiple clips are initialized at the same time you can use the order
parameter to specify which initialization occurs first. Component initialization actions execute when a movie clip symbol is defined. If the movie clip is an exported symbol, the component initialization actions execute before the actions on Frame 1 of the SWF file. Otherwise, they execute immediately before the frame actions of the frame that contains the first instance of the associated movie clip symbol.
Component initialization actions execute only once during the playback of a movie and you should use them for one-time initializations, such as class definition and registration.
Example
The following example code is assigned to the first frame of a movie that is a check box component. The #initclip
and #endinitclip
actions designate the block of statements they enclose as component initialization actions. The enclosed statements register the class and store methods in a prototype object.
#initclip if (typeof(CheckBox) == "undefined") { // Define constructor for (and thus define) CheckBox class function CheckBox() { // Set up our data bindings this.watch ('value', function (id, oldval, newval) { ... }; this.watch ('label', function (id, oldval, newval) { ... }; } // Set CheckBox prototype chain to inherit from MovieClip CheckBox.prototype = new MovieClip(); // Register CheckBox as the class for symbol "Check Box" Object.registerClass("Check Box", CheckBox); // Set up some methods CheckBox.prototype.enable = function () { ... }; CheckBox.prototype.show = function () { ... }; CheckBox.prototype.hide = function () { ... }; // Set up a convenience function to instantiate // check boxes CheckBox.create = function (parentMovieClip, instanceName, depth) { parentMovieClip.attachMovie("CheckBox", instanceName, depth); }; } #endinitclip
Note: If you copy and paste this code into the Actions panel, it will generate an error when the script is compiled because of the undefined functions ({...}
