Flash AS3 Example Tutorial: Rapid production of smoke animation

This example uses the flash to make the smoke animation quickly, mainly utilizes the AS3 class to realize.

First we make a photo of the smoke in Photoshop, which is mainly achieved with Photoshop brushes.

Figure 1

Figure 2

Figure 3

We then move into flash and turn to the original movie clip, named Smokepuff. Then we open the library, then right click on the component and set the link.

Figure 4

Then edit the category and the code below.

Package Com.asgamer.graphics

{

Import Flash.display.BlendMode;

Import Flash.display.MovieClip;

Import flash.events.Event;

public class Smokepuff extends MovieClip

{

public Var Vx:number;

public Var Vy:number;

Public Function Smokepuff (): void

{

Alpha = Math.random ();

VX = Math.random ()-math.random ();

VY = Math.random () * 3-5;

ScaleX = ScaleY = Math.random ();

AddEventListener (Event.enter_frame, loop, False, 0, true);

}

Private function Loop (e:event): void

{

Alpha-= 0.01;

Y + + vy;

x + VX;

ScaleX = ScaleY + 0.02;

if (Alpha < 0)

Removeself ();

}

Private Function removeself (): void

{

RemoveEventListener (Event.enter_frame, loop);

Parent.removechild (this);

}

}

}

The properties of the document are:

Then we create a main.as

Package

{

Import Flash.display.Stage;

Import Flash.display.MovieClip;

Import flash.events.Event;

Import Com.asgamer.graphics.Smokepuff;

Import Flash.display.Sprite;

public class Main extends Sprite

{

Public Function Main (): void

{

AddEventListener (Event.enter_frame, loop, False, 0, true);

}

Private function Loop (e:event): void

{

var smokepuff:smokepuff = new Smokepuff ();

smokepuff.x = 250;

SMOKEPUFF.Y = 250;

Stage.addchild (Smokepuff);

}

}

}
