[Flash] Pirate's Space Game Tutorial, Part 1

[Gavel]

i cant make me die

You obviously didn't read the tutorial properly. Maybe if you actually try to learn from it and understand the actionscript so you can figure out what you did wrong.

[Steyene]

OMG copy pasta. Yours working now spazzy?

[pokit5]

my spawner only spawns in one spot. all the enemies just come like a waterfall at once. code-

onClipEvent (load) {
nextenemy = 0;
enemynum = 30;
enemymin = 30;
enemymax = 50;
}
onClipEvent (enterFrame) {
if (nextenemy == 0) {
nextenemy = 15+random(40);
enemynum++;
_root.enemy.duplicateMovieClip("enemy"+enemynum, enemynum);
_root["enemy"+enemynum]._x = random(_root.stagex);
_root["enemy"+enemynum]._y = -40;
}
if (nextenemy>0) {
nextenemy--;
}
if (enemynum>=enemymax) {
enemynum = enemymin;
}
}



no errors on output .any problem?

In the keyframe have you got a/the 'stagex =' variable.

This tutorial is awesome. However I've got two questions:
1.: When part 2 will be done ?
2.: How should I add more enemy types? Like a mothership or advanced enemies.

[killervirus]

Sorry for double posting but I figured out how to add another enemy type and it can be interesting for the others:

First step:

View the actions of the spawner in the onClipEvent(load) segment add this:

    nextenemy2 = 0;
    enemy2num = 60;
    enemy2min = 60;
    enemy2max = 80;

Second step: Still in the spawner add this bit of code but now in the enterFrame segment, after the original code:

    if (nextenemy2 == 0) {
        nextenemy2 = 15+random(40);
        enemy2num++;
        _root.enemy2.duplicateMovieClip("enemy2"+enemy2num,enemy2num);
        _root["enemy2"+enemy2num]._x = random(_root.stagex);
        _root["enemy2"+enemy2num]._y = -40;
    }
    if (nextenemy2>0) {
        nextenemy2--;
    }
    if (enemy2num>=enemy2max) {
        enemy2num = enemy2min;
    }

Third step:

on the shot mc add this code, after the original, but still in the enterFrame segment:

    for (a=60; a<=80; a++) {
        if (this.hitTest(_root["enemy2"+a])) {
            _root["enemy2"+a].shield -= 1;
            this.removeMovieClip();
        }
    }

Fourth step:

Draw another enemy type and name the instance of it enemy2 on the actions of this mc add these (I made it slower but equipped with stronger shield)

onClipEvent (load) {
    speed = 1+random(5);
    shield = 5;
}
onClipEvent (enterFrame) {
    _y += speed;
    if (shield<=0) {
        _root.expnum++;
        _root.explosion.duplicateMovieClip("explosion"+_root.expnum, _root.expnum);
        _root["explosion"+_root.expnum]._x = this._x;
        _root["explosion"+_root.expnum]._y = this._y;
        _root.kills++;
        this.removeMovieClip();
    }
    if (_root.expnum>_root.expmax) {
        _root.expnum = _root.expmin;
    }
    if (this.hitTest(_root.player)) {
        _root.expnum++;
        _root.explosion.duplicateMovieClip("explosion"+_root.expnum,_root.expnum);
        _root["explosion"+_root.expnum]._x = this._x;
        _root["explosion"+_root.expnum]._y = this._y;
        _root.gotoAndStop(2);
        _root.player.removeMovieClip();
        this.removeMovieClip();
    }
}

Done. I hope it works for everyone.

Edit: There is a bug in it (at least for me) sometimes the advanced enemies just disappear, without even shooting on them. Ideas?

The Pirate - contact me plz.

just so you know, The Pirate is inactive these days. I can send you his msn address if you like, but I don't think he uses flash frequently any more.

I finished this, and with no flaws I assume.
Here's all of the code in the game.

Main Frame on timeline
stagex = 400;
stagey = 600;
expnum = 55;
expmin = 55;
expmax = 75;
Kills = 0;

Player Ship
onClipEvent (load) {
speed = 5;
shotnum = 10;
shotmin = 10;
shotmax = 20;

nextshot = 0;
}
onClipEvent (enterFrame) {
if (this._name == "player") {
if (_x>_root.stagex) {
_x = _root.stagex;
}
if (_x<0) {
_x = 0;
}
if (_y>_root.stagey) {
_y = _root.stagey;
}
if (_y<0) {
_y = 0;
}
if (Key.isDown(Key.SPACE)) {
if (nextshot == 0) {
nextshot = reload;
shotnum++;
_root.shot.duplicateMovieClip("shot"+shotnum, shotnum);
_root["shot"+shotnum]._x = this._x;
_root["shot"+shotnum]._y = this._y;
}
}
if (nextshot>0) {
nextshot--;
}
if (shotnum>=shotmax) {
shotnum = shotmin;
}
if (Key.isDown(Key.LEFT)) {
_x -= speed;
}

_x += speed;
}

_root["enemy"+a].shield -= 1;
this.removeMovieClip();
}
}
}

enemy

}

Make sure the instance names are correct for all objects or this won't work.
In all respect for learning, this should be used as a reference, and not ass a short-cut.
