Explosions!

[zap1992]

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)

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]

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:createEmptyMovieClip("myName",this.getNextHighestDepth());
then you can draw with it: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); }

i am from huangshi,hb,china - a pretty tiny city,it is wonderful here .i am learning .:)

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.

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;
this["p"+i].decay = Math.round(Math.random()*9)+1;
this["p"+i].initXvel = Math.round(Math.random()*-10)+10;
this["p"+i].xvel = this["p"+i].initXvel;
this["p"+i].yvel = Math.round(Math.random()*-10)+10;
this["p"+i]._x = 275+Math.round(Math.random()*-10)+10;
this["p"+i]._y = 200+Math.round(Math.random()*-10)+10;
this["p"+i].onEnterFrame = function() {
this._alpha -= this.decay;
if (this.initXvel<5) {
this._x += this.xvel;
} else {
this._x -= this.xvel;
}
this._y -= this.yvel;
this.xvel -= 1;
this.yvel -= 0.5;
};
}
}
explode();

Hey guys i though i'd give it a go attached is my explosion effect!

[zap1992]

Looks really cool. It would look a bit cooler if it went faster and there were multiple ones of them. Also, if it got bigger before it shrank it would be more realistic. Keep up the good work.
