#initclip

#initclip, 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 (`{...}`)
