I am working on a small flash piece for a site and I was wondering if anyone could help me out.
I am trying to have the words in the flash piece to move randomly across in a set sized box as is. I want it more smooth (not as important though) and I also want a boundary on it so the words stay inside the box that they are in right now. I have a mask over it right now so when the words go across the box, they get cut off instead of staying inside of it. If anyone could help me out on that, that would be great!!!
Please let me know if I confused you! I sooooooooooo appreciate it! Thanks!!!
I tried to attach the flash file, but it was too big (105 kb)… if anyone is interested in helping me out, I can email the flash file to you!
MovieClip.prototype.constrainTo = function(cb){
if (typeof cb == "movieclip") cb = cb.getBounds(this._parent);
var tb = this.getBounds();
if (this._x + tb.xmin < cb.xmin) this._x = cb.xmin + tb.xmax;
if (this._x + tb.xmax > cb.xmax) this._x = cb.xmax + tb.xmin;
if (this._y + tb.ymin < cb.ymin) this._y = cb.ymin + tb.ymax;
if (this._y + tb.ymax > cb.ymax) this._y = cb.ymax + tb.ymin;
}
whereever you have the clip being moved, put after it:
movingText.constrainTo(boxClip);
where boxClip is a movieclip box you want to keep it in. You can also use a getBounds() formatted object if not a movieclip specificalyl
Hi, thanks for replying!! The code I have was used for lines to randomly move, I just replaced the lines with words hoping it would work. It did…but now I want to set the boundary…
This code is placed in the keyframe:
I couldn’t get the code to work for me…I will keep trying though. If anyone can help me out with the code I posted, that would be great.
senocular, the code you posted above…where would the the constrainto code go? I tried many different places in my project, but couldn’t get it right.
I can still email a flash file to anyone…its all done but the boundary code. I really did try to do it all myself. This project is due on Wednesday, I really do appreciate your time. Thanks!
with your case, you really wouldnt need my code. The code you have creates a random span of movement between 0 and the width variable you have at the beginning of your code. Depending on what bounds you want to constrain your movement to depends on this and the setting of
this.targx = Math.random()*width;
to determine that. What you can do is use
(to replace width = 300)
and change
this.targx = Math.random()*width;
to
this.targx = Math.randomRange(100,400)
or where ever it is you want to keep your text within. ^ that sets it to an _x between 100 and 400. This way, whenever a new ‘targx’ is calculated, its kept within those points.
I am so annoying. The code worked perfectly for my random line movement (I have both lines and words doing the same thing with the same exact code), but it didn’t work for my words…any advice? so sorry.
jeez, I don’t understand why its not working…I probably put it in the wrong place or something. It’s like it’s not even being read, it doesn’t matter what I do to change the numbers or anything.
You are right about what you assumed…I don’t want the words to pass the boundary…here is the latest code
Math.randomRange = function(min, max){
return Math.floor(Math.random()(max-min+1))+min;
}
function getdistance(x, x1) {
var run, rise;
run = x-x1;
return (_root.hyp(run));
}
function hyp(a, b) {
return (Math.sqrt(aa+b*b));
}
MovieClip.prototype.reset = function() {
// -------------------
var dist, norm;
this.x = this._x;
this.speed = Math.random()*5+2;
var b = this.getBounds(this);
this.targx = Math.randomRange(100-b.xmin,300-b.xmax);
dist = _root.getdistance(this.x, this.targx);
norm = this.speed/dist;
this.diffx = (this.targx-this.x)*norm;
};
MovieClip.prototype.move = function() {
if (_root.getdistance(this.x, this.targx)>this.speed) {
this.x += this.diffx;
} else {
this.x = this.targx;
if (!this.t) {
this.t = getTimer();
}
if (getTimer()-this.t>1000) {
this.reset();
this.t = 0;
}
}
this._x = this.x;
};
for (i=0; i<5; i++) {
_root.line.duplicateMovieClip(“line”+i, i);
myLine = _root[“line”+i];
myLine._x = Math.random()*width;
}
Thanks again for all of your help…I am not good at this
Let’s see, I do have move on the text movieclips…and they are moving so I am assuming it’s in the right spot. The words just continue on over the set boundary.
I don’t want the words to hit any white area on the left, and then on the right, I want them to stay inside of the first navy blue outline that you see. Basically within the first box that it’s already contained in.
I know I keep saying this, but thank you so much for helping me out. I know you are probably busy, so if you can’t get to this I totally understand. You helped me a ton already…
oh my gosh! It does work for you…haha, ok, I am going to compare code.
I don’t even know how to begin to tell you how much I appreciate your help! Seriously, I know you volunteer your help and I can’t even thank you enough. I hardly ever post, (I just read mainly) but I am glad I did! THANK YOU!
