ActionScript Language Reference

Arguments

thisObj The object on which theFunction is called as a method.

param1, ...paramn

A list of values passed as arguments to

theFunction.

Returns

The return value of theFunction.

Description

The call( ) method invokes theFunction as a method of thisObj, and passes the values of

param1, param2, ...paramn to theFunction as arguments. It is functionally identical to the

apply( ) method, except that it specifies arguments to

theFunction as a comma-delimited

list, rather than as an array. For complete details, see Function.apply( ).

Example

function moveClipTo (newX, newY) {

this._x = newX;

this._y = newY;

}

moveClipTo.call(ball_mc, 100, 200); // Moves ball_mc to 100, 200

theFunction.prototype

Description

The prototype property is the centerpiece of ActionScript’s class and object inheritance

system. By default, it is a generic object waiting to be assigned properties and methods that

will become available to objects constructed by

theFunction. Like any generic object,

theFunction.prototype starts off with the built-in properties __proto__ and constructor.
