Create an Eskiv Flash game tutorial
Posted by Emanuele Feronato on 04/30/08 in Flash, Game design
Do you know a Flash game called Eskiv? No?
Never mind, it's not the best game around there, but there is a thread called Eskiv Clone? in the forum asking help in making a game like that one.
First, play it a minute
Then, take this prototype, starting from an old tutorial called Flash game creation tutorial - part 1.
ACTIONSCRIPT:
-
_root.attachMovie("score","score",1);
-
_root.attachMovie("hero", "hero", 2, {_x:250, _y:200});
-
_root.attachMovie("target", "target", 3, {_x:Math.random()*400+25, _y:Math.random()*300+25});
-
power = 3;
-
enemy_power = 5;
-
points = 0;
-
hero.onEnterFrame = function() {
-
if (Key.isDown(Key.LEFT)) {
-
this._x -= power;
-
}
-
if (Key.isDown(Key.RIGHT)) {
-
this._x += power;
-
}
-
if (Key.isDown(Key.UP)) {
-
this._y -= power;
-
}
-
if (Key.isDown(Key.DOWN)) {
-
this._y += power;
-
}
-
};
-
target.onEnterFrame = function() {
-
dist_x = this._x-hero._x;
-
dist_y = this._y-hero._y;
-
distance = Math.sqrt(dist_x*dist_x+dist_y*dist_y);
-
if (distance<(hero._width+this._width)/2) {
-
points++;
-
score.scoretxt.text = points;
-
this._x = Math.random()*400+25;
-
this._y = Math.random()*300+25;
-
foe = _root.attachMovie("enemy", "enemy", _root.getNextHighestDepth(), {_x:Math.random()*400+25, _y:Math.random()*300+25});
-
foe.dir = Math.floor(Math.random()*4);
-
foe.onEnterFrame = function() {
-
switch (this.dir) {
-
case 0 :
-
this._x += enemy_power;
-
if (this._x>500-this._width/2) {
-
this.dir = 1;
-
}
-
break;
-
case 1 :
-
this._x -= enemy_power;
-
if (this._x<0+this._width/2) {
-
this.dir = 0;
-
}
-
break;
-
case 2 :
-
this._y += enemy_power;
-
if (this._y>400-this._width/2) {
-
this.dir = 3;
-
}
-
break;
-
case 3 :
-
this._y -= enemy_power;
-
if (this._y<0+this._width/2) {
-
this.dir = 2;
-
}
-
break;
-
}
-
dist_x = this._x-hero._x;
-
dist_y = this._y-hero._y;
-
distance = Math.sqrt(dist_x*dist_x+dist_y*dist_y);
-
if (distance<(hero._width+this._width)/2) {
-
points--;
-
score.scoretxt.text = points;
-
this.removeMovieClip();
-
}
-
};
-
}
-
};
And this is the result
Move the purple ball with arrow keys and take the red one. Avoid blue ones and score as much as you can.
This version has better collision detection than the original one
Download and play with it

Very nice, but you sould starting doing tutorials on AS 3.0, since they are so few out there.
It’s a helluva hard to learn, but if we don’t start now we never will…until AS 4.0 comes out and then AS 2.0 becomes obsolete and most of the content on this blog.

Oh and by the way, is the possible for you to add categories for AS 2.0 and AS 3.0?
You probably wrote some As 3.0 games, but I don’t know where to find them.
Take care.

The clones are already popping up on NG… Man, if I could only get some graphics together, before people get bored of it. Nice tutorial.

Nice tutorial. However, I’ve found that I can just ‘avoid’ those ‘bouncy things’ by moving myself out of the ‘gaming area’ :p

Yeah, it’s just a prototype and allows you to cheat easily, but it’s also easy to fix that issue…

Hey,
I remember having this game on my graphic calculator. I don’t think Eskiv was the first version of this game but nevertheless it was a fun addicting time waster.
I think the best thing you did to improve it was take only 1 off when you get hit instead of having to reset at 0. Also maybe you could make the vertical and horizontal dots a different colour? When I’m moving I always move in a vert or hoz direction and I only look for one direction at a time so maybe that could be useful.

Thanks for this. I’ve managed to do the same thing but Ive made it much more complicated for myself! good work!

I might make a game out of this.

Infact, how would you get the enemy to spawn on the targets location ? I don’t know why you would want to do that, but just in case =D.

Hi!
I love this tutorial. Im making a game as we speak but I was wondering could you explain some coding so I can understand it better?
