Flash :: Rotation Control

Rotation Control
Could a mighty god of the FLASH please point me in the direction of a tutorial on how to controll the rotation of an object with the mouse. I have rendered it in Swift 3d v3 and added a roattion to it, so i have a series of frames with the different views all the way around. Now i have imported that into Flash MX.

I need an action script that will control the rotation of the object. Is this the right way to do it?

im shooting for the type of rotation that when you press and hold the mouse over the object you can move the mouse right and left to controll the rotation.

I only want to admit that I want sugar in my tea.

Rotation Control
I would like to be able to control the rotation of a MC via a few buttons - setting the MC to rotate to assigned positions. Instead of just having the MC rotate, I want it to spin (and to control the spin speed) and ease to a stop at the assigned/selected position. This MC needs to rotate on its center point.

Any help would be wonderful. I can get objects to rotate no problem, but I have not been able to control the stop points.

Control AXIS Of Rotation?
is there anyway to dynamically select a coordinate to be the axis of rotation for a movieclip?

the reason is: the user will be able to select any number of different elements and adjust them at the same time but whenever I rotate multiple elements at once I need them to be rotated as a single object from 1 center axis not all from their own axis.

I cannot put them all inside a single movieclip and rotate it either because there are several elements the user is going to be able to drag and drop onto the stage and then they will have the ability to select only the ones they want to rotate. and if they were all in the same mc then the non selected elements would be rotated too.

Thanks.

Rotation With Control Of Mouse...
I would like to seek help in the following file... Where the green arrow would go to the grey arrow with the control of a mouse... The user have to click and hold onto the mouse in order to move the arrow.. However, the user is limited to only the degree from the green arrow to the grey arrow.. Please help if possible...

Rotation Control Delay
Edit Problem fixed.

I have a new question though, how would you go about rotating a velocity to match a movieclips rotation. I`m trying :

this.vectorX = Math.cos(this.rotation) * this.speed
this.vectorY = Math.sin(this.rotation) * this.speed;

but this gives horrible reults

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...

Sound Control With Pause Button As Well As Timeline Control
Hi there

I have a flash page, with a ambient track playing. I added a pause and play button. So you press the button then it stops, then you press it again then it plays...

So now i want to make it so that if you go to the 'WORK' page on the site, wich is on its own frame, and wich has different buttons linking to it, then i want the sound to switch off when i am on the work page as well.
So if the background ambient music plays, and you go to work then the sound switches off. Untill you switch it back on again
How is the best way for me to do that?

How Can I Control A Swf File Via RF Remote Control, Ala Powerpoint?
I have a Mac laptop and Honeywell RF remote that will control Powerpoint presentations. I'd rather make the presentations in Flash. The remote has three functions: last slide, next slide and blank screen. I have no idea what signals the remote sends for Powerpoint to read, but it must be pretty standard.

Does anyone know a way to code Flash so that it will respond to these commands the same as Powerpoint does... or is this a lost cause?

Thanx!

Actionscript Control Then Tweening Control
Ok Flashers, this should be an easy one -

I've animated some movieclips using some embedded MC that are solely actionscript animation routines. Is there a way to now animate that same MC on the timeline using tweening?

It seems that the embedded MC overrides the tweening I place on the timeline, even if I park the embedded MC.

Control A Swf Via RF Remote Control, Ala Powerpoint?
Hi

I am in the middle of a Flash project creating a powerpoint like
presentation to be shown on a projector screen. Flash 9 or a projector.exe

I wonder have you ever had to ask Flash/Flex to control the remote clicker(pointer) buttons using a Front Projection screen ???

I looked on Adobe, Forums and found only this entry,

Topic Title::: How can I control a swf file via RF remote control, ala Powerpoint?

- but don't seem to be able to get to work.

Is there a new method used in AS3? I really need to get my hands on a very simple .flv example.

I need to click to the nest stop(); and click back if needed.

Movie Control...remote Control...
Hi,
I want to create a "remote control" kind of thing for this product demo that I am building.
(go to http://www.autodemo.com/?samples and click on any of the samples and you'll see a movie control on the bottom right).
How do I go about doing it? Thanks!

Game Control Panel --> How2make Object Appear In Control Once Discovered In Game
Hey all you flashies,
here's a problem to scramble the flash nerves. I'm creating a game for my Major project and I want to have a control panel at the bottom. The aim of the game in brief, is to collect 6 pieces of fruit (just an example). These 6 pieces of fruit will be found in different order depending on which route the player takes in the game. What I want to happen is each time the player finds a fruit, I want it to appear in the control panel. How do I go about doing this? Can anyone help? Much appreciated! If anyone has an example to something similar to this it would be much appreciated if I could see it! thanks!

Mouse Control, Out Of Control
I'm working on a Splash screen for a web site.located here I found a bit flash 5 code that is running the "moving images". The problem is that when the mouse is moved left or right from the center too much, the speed of the images goes way to fast.
I am using MX 04 to build this, but I have always used tweens, so I'm a total noob to AS.
What I need is way to limit the speed of the movie clip as the mouse moves away from center. Or limit the area that the mouse can use to effect the movie clip.
Here is the code:
Code:
onClipEvent (load) {
center = 800/2;

}
onClipEvent (enterFrame) {
_parent.dx = center-_root._xmouse;
_x += _parent.dx*.1;
if (_x<-_width/2) {
_x = 0;
}
if (_x>0) {
_x = -_width/2;
}

}
Any help with this would be greatly appreciated,

SWF Control Via Standard Control Bar
We would like to control the playback of SWF movie much like you would a FLV via a standard media control bar. The pre built controls in Flash work well with video FLVs but do not work with SWFs. It is important for our core content files to remain as SWFs as they are true vector animations with an MP3 sound track which we would like our users to be able to pause, start, scan, control volume, etc. Rendering them as FLVs causes a lot of file bloat and the compression is not kind to large areas of flat field color, etc.

These SWFs are prebuilt and exist as separate elements imported into our Flash Project.

So, is it possible to control a SWF as such?

Are there pre built elements for sale anywhere on line so we would not have to build the control code and interface art from scratch?

How difficult would this be to code from scratch if necessary?

THANKS!!!

3d Rotation
I just can't make a 3d rotation. I cant find the way to do it! can somebody help me?

Rotation 3d
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!

How the hell to i get them to spin...clockwise.
I've tried a few ways...cant get them to burn road !!!

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.

newrot = this._rotation + rotspeed
if (newrot > 180){
gotoAndStop(4);
}
this._rotation = newrot

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;
}
}

currently i have ten icons that rotate in response to mouse movement. i also have ten buttons. i want to eventually use the buttons to an effect. i didnt put numbers.. but the top circle is circle number one corresponding to each numbered icon. once a button is pressed i want the numbered icon corresponding to it to rotate and move to the center point. (the red dot in the center of all the icons/ the origin).
heres the link. if this needs more explanation please say so.
thanks.

note: i just left the mouse events on to demonstrate the movement

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!
