Mouse toy

[Headshotz]

Heyo,

In this challenge, try and make something cool that interacts with the mouse, you know, mouse toy

If you have no idea what Im talking about try this example (paste in frame):

//==========
//*~HeadshotZ~*\\
//==========
_root.createEmptyMovieClip("bg_mc", 0);
var stagewidth = 550;
var stageheight = 400;
bg_mc.beginFill(0x000000, 75);
bg_mc.lineTo(0, 0);
bg_mc.lineTo(stagewidth, 0);
bg_mc.lineTo(stagewidth, stageheight);
bg_mc.lineTo(0, stageheight);
bg_mc.endFill();
_root.createEmptyMovieClip("tracer0_mc", _root.getNextHighestDepth());
tracer0_mc.beginFill(0xFF0000, 75);
tracer0_mc.lineTo(0, 0);
tracer0_mc.lineTo(10, 0);
tracer0_mc.lineTo(10, 10);
tracer0_mc.lineTo(0, 10);
tracer0_mc.lineTo(0, 0);
nm = .03;
k = 1;
_root.onEnterFrame = function() {
    for (k=1; k<10; k++) {
        tracer0_mc._x += (_xmouse-tracer0_mc._x)*nm;
        tracer0_mc._y += (_ymouse-tracer0_mc._y)*nm;
        _root["tracer"+k+"_mc"]._x += (_root["tracer"+(k-1)+"_mc"]._x-_root["tracer"+k+"_mc"]._x)*nm;
        _root["tracer"+k+"_mc"]._y += (_root["tracer"+(k-1)+"_mc"]._y-_root["tracer"+k+"_mc"]._y)*nm;
    }
};
i = 1;
for (i=1; i<10; i++) {
    tracer0_mc.duplicateMovieClip("tracer"+i+"_mc", i+100);
}

it could have lived without the background, but it adds a nice touch

you should have used a loop:

for (i=2;i<=10;i++)
{
  this.["tracer_mc"+i]._x += (this.["tracer_mc"+(i-1)]._x-this.["tracer_mc"+i]._x)*nm;
  this.["tracer_mc"+i]._y += (this.["tracer_mc"+(i-1)]._y-this.["tracer_mc"+i]._y)*nm;
}

if you had named the first one "tracer_mc0" or something, you could loop for 1, but that for() loop will just do #2-10

i'll see if i have time to whip up something interesting in the next day or two

Here is my contribution (paste into frame):

lineStyle(0);
moveTo(Stage.width/2, Stage.height/2);
function onEnterFrame() {
    lineTo(_xmouse, _ymouse);
    _rotation += 1;
}

You can draw continents as if it was a map . Wait long enough and it will come back to you...

inspired by astgtciv, i thought i would make something that draws similarly, but also shrinks toward the center each frame.. i was impressed that it only took 16 lines:

createEmptyMovieClip("mc",0);
mc._x = Stage.width/2;
mc._y = Stage.height/2;
arr = new Array();
function onEnterFrame() {
    arr[arr.length]=[mc._xmouse,mc._ymouse];
    mc.clear();
    mc.lineStyle(0);
    mc.moveTo(arr[arr.length-1][0],arr[arr.length-1][1]);
    for (i=arr.length-2;i>=0;i--) {
        a = (Math.acos(arr[i][0]/Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2)))*arr[i][1]/Math.abs(arr[i][1]));
        arr[i][0] = Math.cos(a+.3)*Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2))*.95;
        arr[i][1] = Math.sin(a+.3)*Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2))*.95;
        mc.lineTo(arr[i][0],arr[i][1]);}
    for (i=30;i<arr.length;i++)
    arr = arr.slice(1);}

Awesome, invader! And another tiny upgrade (are we still in the line limit?):

createEmptyMovieClip("mc",0);
mc._x = Stage.width/2;
mc._y = Stage.height/2;
arr = new Array();
function onEnterFrame() {
    arr[arr.length]=[-mc._xmouse,-mc._ymouse];
    mc.clear();
    mc.lineStyle(0);
    mc.moveTo(arr[arr.length-1][0],arr[arr.length-1][1]);
    mc.beginFill(random(0xFFFFFF));
    for (i=arr.length-2;i>=0;i--) {
        a = (Math.acos(arr[i][0]/Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2)))*arr[i][1]/Math.abs(arr[i][1]));
        arr[i][0] = (mc._xmouse + Math.cos(a+.3)*Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2))*.95)*.95;
        arr[i][1] = (mc._ymouse + Math.sin(a+.3)*Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2))*.95)*.95;
        mc.lineTo(arr[i][0],arr[i][1]);
    }
    mc.endFill();
    for (i=30;i<arr.length;i++)
        arr.shift();
    }

uuu......Acid trip!

Nice work so far guys!

[astgtciv]

I was just gonna say something about drugs this version looks like some kind of an animation technique:

createEmptyMovieClip("mc",0);
mc._x = Stage.width/2;
mc._y = Stage.height/2;
arr = new Array();
function onEnterFrame() {
    arr[arr.length]=[mc._xmouse,mc._ymouse];
    mc.clear();
    mc.lineStyle(0);
    mc.moveTo(arr[arr.length-1][0],arr[arr.length-1][1]);
    mc.beginFill(random(0xFFFFFF));
    for (i=arr.length-2;i>=0;i--) {
        a = (Math.acos(arr[i][0]/Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2)))*arr[i][1]/Math.abs(arr[i][1]));
        arr[i][0] = (mc._xmouse + Math.cos(a+.3)*Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2))*.95)*.95;
        arr[i][1] = (mc._ymouse + Math.sin(a+.3)*Math.sqrt(Math.pow(arr[i][0],2)+Math.pow(arr[i][1],2))*.95)*.95;
        mc.lineTo(arr[i][0]/(1+Math.random()/4),arr[i][1]/(1+Math.random()/4));
    }
    mc.endFill();
    for (i=30;i<arr.length;i++)
        arr.shift();
    }

wow! those are pretty intense

that's one of the cool things about working with trigonometric functions, they can go crazy and sometimes look quite cool!

Nice work everyone so far, keep them coming.

Yeah I changed it.

Ill add something good.

there was nothing wrong with the example. i was just recommending a way to optimize it a little bit
