Well, are you doing it by duplicating an mc or a bitmap or many stars? can u give a screenshot of what you want?

make a new movieclip with the star in it, and set it's linkage to export for actionscript, with a linkage id: "star".

then put this code root

Code:

speed = 10;
star = function() {
this._y = this._height * -1;
this._x = Math.random() * Stage.width;
}
Object.registerClass("star", star);
star.prototype.onEnterFrame = function() {
this._y += speed;
//
if (this._y > Stage.height) {
removeMovieClip(this);
}
}
//the code to add stars:
this.onEnterFrame = function() {
starCount++;
_root.attachMovieClip("star", "star_"+starCount, starCount);
}

i think this should work. i've not got flash installed atm so i can't check it. unless there's any bugs in it, it will.

hope this helps

Umm it didnt work.. So?
First i need to inser new movie clip? Do I name it star and linkage id star export for actionscript? then i draw the star into the movie clip? Then i need to place the star to the stage and enter actionscript?

and I need bit more help with this game..
If enemy hits the hero its shield goes to "damage" frame?

Woohoo! I got the shield damage to work by myself!

hey cyberalthete i can never see what u post for some reason, it looks like this to me:

then put this code root

i think this should work. i've not got flash installed atm so i can't check it. unless there's any bugs in it, it will.

where i'm guessing they'res supposed to be code after the root, not a gap? is they're something wrong with my browser?

Then i need to place the star to the stage and enter actionscript?

no, u just leave it in the library, if you give it a linkage name, flash will be able to find it with attachMovie

I cant get it working.. Could you send me .fla?

And i need some help with secondary fire.

sorry i can't get to flash atm but i had this on disk of a fishy game i started making, the first frame (menu) has bubble's coming up if you wait long enuf, the code for that is on the first frame, not in the timeline but on the right side of the stage (from memory)

hope it helps

Ok i got it working somehow.. but how do i make it so that the stars move down without mouse. Hope you get the point

**icio** · November 14th, 2004, 10:39 AM

well, i used attachMovieClip instead of attachMovie.. Woops. !! try fixing that:

Code:

speed = 10; 
star = function() { 
this._y = this._height * -1; 
this._x = Math.random() * Stage.width;
}
Object.registerClass("star", star);
star.prototype.onEnterFrame = function() {
this._y += speed;
//
if (this._y > Stage.height) {
removeMovieClip(this);
}
}
//the code to add stars:
this.onEnterFrame = function() {
starCount++;
_root.attachMovie("star", "star_"+starCount, starCount);
}

hope that helps

So.. Do i need to but that script into the frames actions? And do i need to check "export in first frame"?

By the way heres the swf of my game..

why don't you just use the same method that you have used to do the bullets?
except make them move down, and make their _x property random.

but to answer your question, put that code in the frame with the ship in it, of the main timeline.for export in first frame, try it with and without, with if it's default.

Wtf?! This is weird.. If i but the star script on the layer where the hero is the stars will work but if health is zero it goes to gameover frame script wont work..

This is my the script what i have in the hero layer:

PHP Code:


 _root.onEnterFrame = function() {
if (score>11900) {
_root.gotoAndPlay("mission");
} else {
trace(score);
}
if (health<10) {
gotoAndStop("gameover");
} else {
trace(health);
}
}
_root.score = 0;
_root.health = 100;
stop();
speed = 10;
star = function() {
        this._y = this._height * -1;
        this._x = Math.random() * Stage.width;
}
Object.registerClass("star", star);
star.prototype.onEnterFrame = function() {
        this._y += speed;
        //
        if (this._y > Stage.height) {
                removeMovieClip(this);
        }
}
//the code to add stars:
this.onEnterFrame = function() {
        starCount++;
        _root.attachMovie("star", "star_"+starCount, starCount);
}
