Flash :: 180° Rotation Newbie Problem

Rotation With Actionscript - NEWBIE
I'm trying to rotate an object slowly around its center and tweening just doesn't go slow enough. The tween currently runs over 400 frames and that's just far too many, especially when I'm sure that Actionscript would be able to do it alot easier and smoother.

Only problem is that I don't know much actionscript past the standard gotoandplay etc so could anyone let me know the best way to go about this or point me to a site where I could learn basic movement by using actionscript please.

To give a clearer idea of what I'm trying to do click here

Each of these symbols will be opening up a page on the site. Ideally I'd like to have the rotation stop each time one of the symbols is clicked on. For now though I'd just like to know how to rotate using Actionsript cos I know what I'm like, newbie confusion etc.

Hope someone can help. Thanks

Newbie Rotation Issues
I've looked around the forum (probably not hard enough) and I'm still looking, but I haven't seen this question pop up anywhere. My problem is that I would like to have a movie clip rotate around a static focal point while also being able to move up, down, left, right, without changing the point on the screen in which it rotates from. I'm trying to find ways to clarify what I mean, but I'm having trouble right now. If this doesn't make sense, then let me know. I will try and rephrase it better. Thank you.

Image Rotation (newbie)
I am new to flash, but experienced in HTML. I would like to create a flash site entrance that has a spinning record (I have the image) that spins for 5 - 7 seconds and then stops with the text of the label upright and readable then has the word "Enter" fade in and then repeats. I am sure this is probably a simple project but all I can accomplish so far from tutorials that I have searched for is to rotate the record 180 degrees. Any help would be appreciated.

Thanks

Clip Rotation For Movement: A Newbie Asks
Hi All,

I pretty new to actionscript and following a few tutorials. I've been playing with one that moves a movieclip towards the point at which you click the mouse and wanted to rotate the clip towards the target point.

I have it almost working but when you click the mouse on or very close to the x or y axis of the clip the rotation angle gets all screwed up. As soon as you click further away from them the rotation returns to normal.

Here's the code in the movement frame of the clip:

//calculate movement rate for each axis
x = Math.abs(xstart-xtarget);
y = Math.abs(ystart-ytarget);
if (x>y) {
xspeed = 5;
yspeed = 5*(y/x);
} else {
yspeed = 5;
xspeed = 5*(x/y);
}
// Calculate the angle from the current clip position to the target position
angle =Math.atan(x/y);
trace (angle);
// Convert from Rads to Degrees
angle = angle*57.2957;
//Check which quadrant the target is in and adjust accordingly
if (_x<xtarget and _y<ytarget) {
angle = angle+90;
}
if (_x>xtarget and _y>ytarget) {
angle = angle+270;
}
if (_x>xtarget and _y<ytarget) {
angle = angle+180;
}
//Rotate the CLip
setProperty (this, _rotation, angle);
trace (angle);
//Move the clip
with (_root.arrow) {
if (_x>(xtarget+2.5) || _x<(xtarget-2.5) || _y>(ytarget+2.5) || _y<(ytarget-2.5)) {
if (_x>xtarget) {
_x = _x-xspeed;
} else {
_x = _x+xspeed;
}
if (_y>ytarget) {
_y = _y-yspeed;
} else {
_y = _y+yspeed;
}
}
}

The basic movement tutorial was from actionscripts.org

Thanks in advance

Rotation Script - Smooth Rotation
I have created a speedometer and on clicking a speed, I can get the needle to rotate around to the speed clicked, using _rotation.

However, the movement is very 'jumpy' and I would like to make it smoother, or better still accelerate/decelerate.

I have tried the following

Quote:

on (release) {
rotation_speed = 0.1;
if (speedo._rotation > -40)
{
do {
rotation_speed = rotation_speed * 1.1;
speedo._rotation = speedo._rotation - rotation_speed;
} while (speedo._rotation > -40);
}
else {
do {
rotation_speed = rotation_speed * 1.1;
speedo._rotation = speedo._rotation + rotation_speed;
} while (speedo._rotation < -40);
}
}

I want to get the needle round to -40, so whilst it is greater rotate is backwards, otherwise rotate forwards, starting with a small rotation and increasing (accelerate).

I found that this was still jumpy. Trying a negative causes Flash warning about script running for too long.
Rotating forwards (else) also overshoots the end position of -40

Any ideas on how to get the needle moving smoothly and finishing on the correct spot??

Rotation At A Given Rotation Point In AS
Hey ya'll.
I was wondering on exactly how would you make an MC rotate with a given rotation center, using AS, obviously. I'd like to know the math behind it, please.
Using _rotation would make it rotate around the mc's center... i'd like to make it rotate around another center, one defined...

Ok Gibbosniper,

This is the start of the thread, for our contest of Newbies brains in action. Let us set a time limit of sorts, and go from there.

Again, I am far from an MX master, I just started just over a week ago, so it might take a while for me to produce something worthy of public display, but if you are patient, so am I.

Keyboard Control-for A Very Newbie Newbie
I was wondering if there is a simple way to control flash animations when
pressing a key on the keyboard. Example: Scene 1 is an animation of a
circle, this scene will continue to loop until I press the 'f' key, and
then the flash movie will change to Scene 2 where we see the circle
explode. I looked around flashkit.com and found some tutorials, but I
think they used an earlier version of flash, because I can't find the
instance properties in order to change the action from mouse click to key
press. I own flash professional 8. Anyway, I can use as much help as I
can get, so if you know of an action parameter in which I can execute
this...action, it would be greatly appreciated! Thank you for your time!

Newbie Asking A Newbie Question
Thanks for looking at my post. I am very new to Flash and I want to make a simple movie withsome text. I know how to insert text and customize it, but I wanted to know how I could jazz it up a bit. Add some effects to it. I was wondering if anyone could help show me how to make it shine, or glimmer, or glow, or something of tht sort, you know? You know on the Ultrashock logo when you put your mouse over it, it shines? I wanna know stuff like that. Can anyone help? Is there a tutorial or we page I can go to? Thanks in advance, and thanks for looking even if you can't help...

k i made some 3d letters... and they are in flash... i have them set as a mc and i have a button hidden under them.... on the mouse over of the button the mc starts playing, and the letters rotate, now i would like the letters to continue rotating after the mouse leaves, but when the letters return to the orignal state i want them to stop.... but when the mouse is still over the button i want the letters to continue to spin even when they reach the orignal position... Thank you for your time!

Rotation
Hey, I have what should seem to be a simple problem. I made a movie that has a throwable object in it, that will bounce back off of the walls. Gravity is also thrown in there, and the ball will eventually stop at the bottom of the screen if left alone. My object is a gear. What I want it to do is to rotate according to the xvelocity. Before I go on I have to give credit to Bit-101, as it is more or less his tutorial that it's from.
Anyways, I want the gear to rotate in the direction that it's moving, and like I said, I would like it to be proportional to the actual speed. I have tried a to just add a little code to the ball. _rotation = xvel where xvel is obviously my xvelocity. For some reason that didn't work. All of my script is on the object, which just consists of three frames. The first is just variables for like the leftedge, rightedge, etc, initial velocities. The third is gotoandplay(2); and the second is where all of the script is. If you want to see the gear in action, go to: http://www.mime.eng.utoledo.edu/intro1.swf The gear that I am talking about is the first one that drops at the beginning. Note: you will need the Flash 6 Player to view it correctly.
Thanks in advance for any help

Rotation Help
I am trying to rotate and object 360 and make it stop. I have included the code I am using below. I have tried entering many different numbers in place of the 180 but they don't work. Any help would be greatly appreciated.

Rotation
I am new to flash and I am wondering if there is a way to have a 3d object or text rotate in a 360 degree plane?

3d Rotation
I am trying to rotate a point about y axis. I have written the code as follows in the onmouse release event of a button. I am trying to a movieclip by assigning the rotated point to _x property of the movie clip. THe code is as follows

on (release) {
xyangle = xyangle+10;

// formula for rotating about y axis
//x' = (cos é * x) + (sin é * z)
//y' = y
//z' = -(sin é * x) + (cos é * z)

tmp = -(Math.sin(xyangle*_root.pi180)*x1)+(Math.cos(xyang le*_root.pi180)*z1);
x1 = (Math.cos(xyangle*_root.pi180)*x1)+(Math.sin(xyang le*_root.pi180)*z1);
z1 = tmp;
screenx = ((800/2)*x1)/(z1+100)+(800/2);
screeny = ((600/2)*y1)/(z1+100)+(800/2);
setProperty (_root.test, _x, x1);
setProperty (_root.test, _y, y1);
}

I am declareing the following variables in a frame in main timeline

x1 = 0;
y1 = 0;
z1 = 50;
sin = 0.9848;
cos = 0.1736;
xyangle = 10;
pi180 = 0.01745392;

I feel there is something I am missing because the rotation is not smooth and I am not getting a desired result

i was wondering how i could keep a layer to have something rotate over and over again at teh end of a movie... or blink really really fast at the end of the movie clip... any ideas??? thanks. i know supposedly you can't loop just a layer with a tween. thanks for the help.

Is There A Rotation
Ok, I have this circle - divided into 8 "pie slices" - that I rotate/spin at some constant rate.

What I would like to be able to do is once an input event (button, mouse click, etc) happens have the circle slow down and stop exactly say 1.5 rotations (540 degreees) from the point of the rotation it was at when the trigger to stop it was fired.

Now, per the subject line, is there some variable (similar to say the X:Y coords) that tells you what point in a rotation a MC is at? (ie "rotation.status = 245 degrees")

If there is, great..then thats basically all I need.

If not, how the heck could I determine where in the rotation a MC is?

If what Im asking doesnt make any sense...think of the Wheel of Fortune. With the initial spinning being done by your hand. The "event/trigger" being the release. And, the 540 degrees being the "easement"

Help?

Ahhhk!

Rotation
Hello,

i was working on some functions like moving a MC, Fading a MC but there is one i have a problem:

What i want is this:

1. My MC is stoped.
2. I want to give a command to make it rotate...first he starts to rotate...acelerates and then keeps rotating at a constant speed.
3. When i want i give a command and make it stop. But he stops by desaceleration on not in an instant.

Could someone help me to do this...

I was thinking on a prototype or a function as i will apply this to several MC's.

Thanks,
Miguel

3d Rotation
I need help with actionscript.
I want to create a 360 degree rotation of an object using the cursor to rotate left or right when on the object.
I have 15 png images completing the rotation.

Also, I need actionscript. When viewing text in a text box, instead of scroll bars, I would like the text to automatically scroll slowly when the cursor is over the text and to review the text, left click and drag to manually move the text up or down, on release, the text should continue the scroll.

Thankyou for your input. Tracy James tracyjame@aol.com

MC Rotation
Hello,

i have a MC on my main timeline.
i also have 2 buttons: one for "play" and one for "stop".

I want to create some actionscript code which does the following to the MC when the "play" button is pressed:

1. Starts rotating the MC increasing its speed from zero to a certain speed.
2. Keeps the MC rotating at that speed until the button "stop" is pressed.

When the "stop" button it's pressed, that MC will decrease it's rotation speed to zero.

Sometime ago i created a function which moves linearly a MC from point A to B with easing...i tryied starting from there but with no sucess...i am having problems in the sequence: acelerate, keep at same speed, desacelerate when "stop" is pressed.

Could someone help me?

My linear moveMC function is the following:

// Begin of Move Function
function myEnterFrame() {
var dx= this.targetX - this._x;
var dy= this.targetY - this._y;
if ((dx > -.1 && dx < .1) && (dy > -.1 && dy < .1)) {
this._x = this.targetX;
this._y = this.targetY;
delete this.onEnterFrame;
} else {
this._x+=dx*this.speed;
this._y+=dy*this.speed;
}
}
function moveMC (clip,targX,targY,v) {
clip.targetX = targX;
clip.targetY = targY;
clip.speed = v;
clip.onEnterFrame = myEnterFrame;
};
// End of Move Function

Hope it will give u some help, or if you prefer just indicate me something from scratch.

Thanks,
Miguel

Rotation, Rotation, Rotation
Heres the deal i have an mc "hero" which rotates and changes. I have another mc "bullet" which holds the code. The code works fine but the problem is that the hero changes modes and the positions of x and y from which the bullet fires also changes. But when I rotate the hero the bullet does not stay in the correct position.
The code is all kept on the "bullet" mc.

Code:
onClipEvent (load) {
_root.bullet._visible = false;
/:count = /:count+1;
if (_root.heromodes=="mode1") {
xmod = 0;
ymod = -33;
} else if (_root.heromodes=="mode2") {
xmod = 15;
ymod = -34;
} else if (_root.heromodes=="mode3") {
xmod = 5;
ymod = -28;
}
_x = _root.hero._x+xmod;
_y = _root.hero._y+ymod;
speed = 16;
xSpeed = speed*math.sin(_root.hero._rotation*(math.pi/180));
ySpeed = speed*math.cos(_root.hero._rotation*(math.pi/180));
}
onClipEvent (enterFrame) {
_x = _x+xSpeed;
_y = _y-ySpeed;
if (!_root.bounds.hitTest(_x+x, _y+y, true)) {
} else {
this.removeMovieClip();
}
}
onClipEvent (enterFrame) {
if (Key.isDown(Key.SPACE)) {
this.duplicateMovieClip(/:count+1,/:count+1);
}
}
I think the problem is in the:

Code:
xSpeed = speed*math.sin(_root.hero._rotation*(math.pi/180));
ySpeed = speed*math.cos(_root.hero._rotation*(math.pi/180));
(I didn't know this was gona be so long,I apologise)

3d Rotation
I've tried a couple of forums now with no success. Im no expert but at the same time im sure this is achievable...cos I've seen stuff like this before?!
I have a bit of script which is revolving an object around a central point. All i want is it to be interactive...so that when i move the mouse to the right side of the screen for example (ie. "_xmouse > 250") it orbits right and to the left side of the scrren it rotates left. It would be even cooler if it acted with acceleration... so it moved faster and then obviously slower as you moved the mouse towards the center of the stage. It's just a case of doing something with the variable "speed" and the "_xpositon" i guess??. But i dont know how cos its hard!... any help would be hugely appreciated. If im not making yselkf clear please loet me know..
Thanks...

This is the script I have so far...

onClipEvent(load){
y=100;
speed=5;
radius=100;
xcenter=250;
ycenter=200;
zcenter=100;
angle=0;
fl=150;
}

onClipEvent(enterFrame){
z=Math.sin(angle*Math.PI/180)*radius+zcenter;
scale=fl/(fl+z);
x=Math.cos(angle*Math.PI/180)*radius;
_x=x*scale+xcenter;
_y=y*scale+ycenter;
_xscale= _yscale = scale*100;
angle+=speed;
if(angle>359){
angle-=360;
}
}

Help With Rotation
OK, here is what I want to do. I have a circle with a triangle marker on it. Outside of the circle there are 4 points. When you click on one of the points, the circle rotates around so that the triangle is pointing at the point. Just rotation I don't want the X or Y position of the circle to change. Then when you click on another point it rotates to that one. How can I do this with actionscript. I want to keep the file small. Just the image and the points. Thanks.

Help With 3D Rotation
Can someone give me an explanation or a really good web tutorial site on how to fully rotate an object on x, y and z axis around a circle? I've been working alot with the rotations recently and sin/cosine, but as soon as I tried delving into 3D this morning my brain just kinda went *Klunk!* and I've been stuck.

If I want to do a standard rotation I use the following:

onClipEvent (load) {
n = 0;
speed = .1;
radius = 75;
diameter = radius*2;
centerX = _parent.ball2._x;
centerY = _parent.ball2._y;
}

onClipEvent (enterFrame) {
n += speed;
this._x = Math.cos(n) * radius +centerX;
this._y = Math.sin(n) * radius +centerY;
}

For rotation just on X and Z Axis I use something like this....

onClipEvent (load) {
n = 0;
speed = .1;
radius = 75;
diameter = radius*2;
centerX = _parent.ball2._x;
centerY = _parent.ball2._y;
}

And for rotation just on Y and Z Axis I use something like this....

onClipEvent (enterFrame) {
n += speed;
this._x = Math.cos(n) * radius +centerX;
this.yscale = ((Math.sin(n) * radius +centerX)-150);
this._xscale = ((yscale/diameter)*100);
this._yscale = ((yscale/diameter)*100);
}

// Y Rotation with Z Depth
onClipEvent (load) {
n = 0;
speed = .1;
radius = 75;
diameter = radius*2;
centerX = _parent.ball2._x;
centerY = _parent.ball2._y;
}

onClipEvent (enterFrame) {
n += speed;
this._y = Math.sin(n) * radius +centerY;
this.xscale = ((Math.cos(n) * radius +centerX)-150);
this._xscale = ((xscale/diameter)*100);
this._yscale = ((xscale/diameter)*100);

}

These parts I got figured out ok but I can't seem to combine them so I can use the X, Y, and Z-Scale axis rotations all together. I'm sure the answers sitting right there but I'm just not seeing it.

Like in the first example for standard rotation, COS calculates X, SIN Calculates Y, so what would calculate Z?

As near as I can tell in order to use all 3 rotations I would need to calculate X, Y, XZ, YZ, ZX and ZY positions? Or maybe my brain has just turned to Jello.

Either way I've been playing with this all day and can't seem to figure it out so I'd really appreciate any help I can get - Thanks!

Rotation
Hi,

i have a circle MC that i want to have rotation when i mouse over it and when i mouse out of it, i want it to stop rotating.

I want the circle to start rotating smoothly, 0,1,2,3,4,5, ect. and when you mouse out of it, i want it to stop rotating smoothly, 100,99,98,97,96,95, ect...

Now, i tried doing this with motion tween, but it's not smooth at all and i can't get it to spin fast enough (even with very high frame rate), also, it jerks and looks really ugly.

I was thinking maybe there is an easier way of making it spin with A/S and have it be more smooth.

I just need the A/S.

Thanks,
