Simple meteor shower animation special effects code

In this tutorial, you will learn how to create a horizontal menu.

(This everyone will do) the whole process is a frame code:

Xrandom = new Array ();

Yrandom = new Array ();

Salerandom = new Array ();

Get random speed

Speed = Math.floor (Math.random () *10) +5;

For (_global.i=0 i<=19; i++) {

Get Random Horizontal

Xrandom = Math.floor (Math.random () *700);

Get random ordinate

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

Get a random size

Salerandom = Math.floor (Math.random () *20) +2;

Create 19 Comets

Duplicatemovieclip (Ball, "ball" +i, I);

_root["Ball" +i]._x = xrandom;

_root["Ball" +i]._y = yrandom;

_root["Ball" +i]._yscale = salerandom;

Meteor Angle is 20.

_root["Ball" +i]._rotation = 20;

The radian displacement of a meteor into 20°.

_root["ball" +i].onenterframe = function () {

var a = this._rotation;

var rad = a*math.pi/180;

var dx = Math.Cos (RAD) *speed;

var dy = Math.sin (rad) *speed;

this._x = + dx;

This._y + dy;

If the meteor exceeds the screen, the coordinates are restored.

if (this._x>=710) {

this._x =-math.floor (Math.random () *300);

this._y =-math.floor (Math.random () *300);

}

};

}

Get ASCII

Code = 174;

char = chr (code);

Author name

Mytext_txt.text = char+ "Huanbaiyiju";

Okay, OK!

Special Note:

An array is an interesting thing to do, like to create thousands of enemies:

Enemys = new Array ();

for (i=0;i<500;k++) {

Enemys.names = "Zerg";

Enemys.blood = 200;

Enemys.equipment = "Sword";

}

All the attributes of the enemy are simply defined.

Debug it, see the effect ....
