ActionScript Language Reference

The .fla file for this example is available at the online Code Depot:

// Attach this onLoad() handler to a clip named star0

onClipEvent (load) {

// Place the current clip at a random position

_x = Math.floor(Math.random() * 550);

_y = Math.floor(Math.random() * 400);

// Reset clip scale so we don't inherit previous clip's scale

_xscale = 100;

_yscale = 100;

// Randomly size current clip between 50 and 150 percent

randScale = Math.floor(Math.random() * 100) - 50;

_xscale += randScale;

_yscale += randScale;

// If we're not at the 100th star, make another one

if (_name != "star100") {

nextStarNumber = Number(_name.substring(4, _name.length)) + 1;

this.duplicateMovieClip("star" + nextStarNumber, nextStarNumber);

}

}

MovieClip.onMouseDown() Event Handler

handler executed when primary mouse button is depressed while the clip is on stage

Flash 5; callback form introduced in Flash 6

mc.onMouseDown()

onClipEvent (mouseDown) {

statements

}

Description

The onMouseDown() event handler is the callback form (and more modern analogue) of

the legacy onClipEvent (mouseDown) event handler. The onMouseDown() event handler is

identical to the Mouse.onMouseDown() listener event, except that it allows for screen

refreshes between frames ...
