Explosions!

zap1992 · 02-14-2006, 10:03 PM

Lets see.... Any type of explosion including volcanoes, particles, bombs, fades, and just about anything you can think of... I think this should be 50 lines or less as to allow for a full spectrum of..... scripts. Let the games begin?

Note: I will post my 'entry' ASAP

how about 36 lines? (i recommend using 30+ fps)

ActionScript Code:

size = 100;
howMany = 5;
function createBoom() {
    if (depth>20) {
        depth = 0; }
    depth++;
    createEmptyMovieClip("boom"+depth,depth);
    boom = this["boom"+depth];
    boom.onEnterFrame = function () {
        this.Scale += this.rate;
        this._xscale = this.Scale;
        this._yscale = this.Scale;
        this._alpha = 100 - this.Scale;
        if (this.Scale>=100) {
            createBoom();
            this.removeMovieClip(); } }
    boom._xscale = 0;
    boom._yscale = 0;
    boom.Scale = 0;
    boom.rate = 5+Math.random()*10;
    boom._x = Math.random()*550;
    boom._y = Math.random()*400;
    boom.lineStyle(0);
    boom.moveTo(size,0);
    for(a=1;a<12;a++) {
        x = .1*size*Math.cos((a-.5)*Math.PI/6);
        y = .1*size*Math.sin((a-.5)*Math.PI/6);
        ax = size*Math.cos(a*Math.PI/6);
        ay = size*Math.sin(a*Math.PI/6);
        boom.curveTo(x,y,ax,ay); }
    x = .1*size*Math.cos((a-.5)*Math.PI/6);
    y = .1*size*Math.sin((a-.5)*Math.PI/6);
    boom.curveTo(x,y,size,0); }
depth=0;
for (i=0;i<howMany;i++) {
    createBoom(); }

Im looking through your code and I don't see anything that makes the graphic! Is "boom" a built in graphic or something?

zap1992 · 02-16-2006, 01:12 AM

boom.lineStyle(0);
boom.moveTo(size,0);
for(a=1;a<12;a++) {
x = .1*size*Math.cos((a-.5)*Math.PI/6);
y = .1*size*Math.sin((a-.5)*Math.PI/6);
ax = size*Math.cos(a*Math.PI/6);
ay = size*Math.sin(a*Math.PI/6);
boom.curveTo(x,y,ax,ay); }
x = .1*size*Math.cos((a-.5)*Math.PI/6);
y = .1*size*Math.sin((a-.5)*Math.PI/6);
boom.curveTo(x,y,size,0); }

EDIT:Oooohhh... thats pretty cool (hadn't tried it until now) sorry about my code not existing yet :-P ill get on it

nice!

sometimes you question people who start challenges but don't include an example. however, i really liked yours. had a bit of a lava look to it. awesome. i did get errors when i tested it. perhaps it's the for() loop in the onEnterFrame starting at x=1, when the dot#'s were created starting at #2

@falltimemusic
it uses Flash's drawing API. you can create a movie clip using code:

ActionScript Code:

createEmptyMovieClip("myName",this.getNextHighestDepth());

then you can draw with it:

ActionScript Code:

createEmptyMovieClip("myName",this.getNextHighestDepth());
myName.lineStyle(0); // sets the appearance of the line
myName.moveTo(size,0); // moves the position where it starts drawing
size=100;
for(a=1;a<12;a++) {
x = .1*size*Math.cos((a-.5)*Math.PI/6);
y = .1*size*Math.sin((a-.5)*Math.PI/6);
ax = size*Math.cos(a*Math.PI/6);
ay = size*Math.sin(a*Math.PI/6);
myName.curveTo(x,y,ax,ay); } // draws a curve to the next point. you can also use .lineTo()
x = .1*size*Math.cos((a-.5)*Math.PI/6);
y = .1*size*Math.sin((a-.5)*Math.PI/6);
myName.curveTo(x,y,size,0); }

fireworks anyone? =D
NOTE: You can have multiple fireworks at once!! but watch out, if you turn up maxbursts too high you get some serious lag (unless you turn down detail that is)

Code:

function onLoad() {
    //change any of these variables
    detail = 150;
    angle = -90;
    spread = 360;
    size = 26;
    maxburst = 2;
    //Dont change anything below here
    countz = -1;
    ticker = -1;
    createEmptyMovieClip("background", 1);
    background.beginFill(0x000000, 100);
    background.lineTo(0, 0);
    background.lineTo(550, 0);
    background.lineTo(550, 400);
    background.lineTo(0, 400);
    background.lineTo(0, 0);}
function onMouseDown() {explosionsize = random(10) + 5
    xmouse = _root._xmouse;
    ymouse = _root._ymouse;
    createEmptyMovieClip("particle", 0);
    particle.lineStyle(10, Math.round(Math.random()*0xFFFFFF+1), 50);
    particle.lineTo(0, 0);
    particle.lineTo(0, .5);
    countz++
    if (countz>=maxburst) {countz = 0;}
    for (x=2+(countz*detail+1); x<=(countz*detail+1) + detail+1; x++) {
        particle.duplicateMovieClip("dot"+x, x);
        _root["dot"+x].rand = random(100);
        _root["dot"+x]._alpha = _root["dot"+x].rand+15;
        _root["dot"+x]._width = _root["dot"+x].rand/100*size;
        _root["dot"+x]._height = _root["dot"+x].rand/100*size;
        _root["dot"+x].angle = (random(spread)+angle-spread/2)*Math.PI/180;
        _root["dot"+x].distance = 5;
        _root["dot"+x].speed = Math.random()*2+explosionsize;
        _root["dot"+x].X = xmouse;
        _root["dot"+x].Y = ymouse;
        _root["dot"+x]._x = xmouse;
        _root["dot"+x]._y = ymouse;}}

                    ang = angle/(Math.PI/180);
                    angle = ang*(Math.PI/180);
                    distance += speed;
                    speed -= 1;
                    _y = Math.sin(angle)*distance+Y;
                    _x = Math.cos(angle)*distance+X;
                    _alpha -= 3;
                } else {if (_y<=Stage.width) {_alpha -= 3;
                        speed -= 1;
                        _y -= speed/2;
                        diff = X-_x;
                        _x -= (Math.abs(diff)/diff)*Math.abs(diff/100);}}}}}}

Here is my explosion. It is based on an explosion class I made almost a month ago. Also this is the first time I've entered some code in a challenge.

Code:

this.createEmptyMovieClip("p0", 100);
p0._x = 275;
p0._Y = 200;
p0.lineStyle(1, 0xff0000, 100);
p0.moveTo(0, 0);
p0.lineTo(0, 3);
pNum = 1000;
function explode() {
	for (i=0; i<pNum; ++i) {
		duplicateMovieClip("p0", "p"+i, i);
		this["p"+i]._alpha=100;

I think this should be 50 lines or less as to allow for a full spectrum of..... scripts. Let the games begin? Note: I will post my 'entry' ASAP
