I feel dumb for asking this....but what is the best way to make an object rotate (counter-clockwise in this case) indefinitely? ENTER_FRAME listener that offsets the angle by a certain number of degrees per frame? more economical way?
View 3 RepliesI have a Cube which I want to rotate using mouse motion. So if I move my mouse to the left it rotates as if rotationX was increased. When I move right rotationX is increased. Moving Up and Down alters rotationY.
This looks fine as long as you modify only one dimension (either rotationX or rotationY). But if I have already changed rotationX and then try to modify rotationY the results are weird. If rotationX is 180 rotationY effects are reversed. It basically is quite unpredictable and certainly not suitable for user.
I have tried to look around (failed), read about quaternions (couldn't understand), tried some out of blue and very complex trigonometric calculations (made a fool out of myself) and so I am stuck now. I've found this SO question Best way to translate mouse drag motion into 3d rotation of an object but it doesn't help me a bit, I can't understand any of the answers, really.
I have a papervision camera of which turns using keyboard input, I have a radar of which I would like to orientate to direction when the camera turns.I have it all working apart from mapping my (camera) DisplayObject3D.rotationY to RadarInterface.rotation correctly.The camera (or any 3d object) works with values I'm finding hard:Clockwise: 0 to 89, 89 to 0, -0 to -89, -89 to -0 doing a complete 360.So if I were to turn 180 degrees I'd go from 0 to 90 and back down to 0 again.
View 1 RepliesI have an object, the center of the object I believe is the rotation point. When I click transform and edit the rotation properties on the right side to like 55 degrees then it works, it rotates from the point it's suppose to and looks great. The problem is when I use AS .rotation on the object, I have no idea where it's rotating from and it's going all over the freaking place. I assumed it would rotate from the same rotation point as the transform tool rotates the object from. I also assumed 0-360 was the options for rotation. What am I doing wrong? from the looks of it's odd rotation I can't even tell where it's centering.
View 3 RepliesI need to move between (rotated) object in flex along x, y, or z as an independent observer. The movement relative to x, y works ok, but when I go along the z axis, the observer behaves as it was apart of the xyz system of the objects and doesn't go straightforward to the object but in diagonal for example.

I would like to force objects to have the same rotation for images showed when mouse is rollover. Right now the images are shown relative to the rotation of the object the mouse is over.How do I force the rotation to make the mouse over image stay portrait?I have the same problem with the scale of the images. Right now the images are scaled relative to the objects the mouse is over...
ActionScript Code:
mouseoverimage1.scaleX = _origXScale;
mouseoverimage1.scaleY = _origYScale;

I am completely new to AS and have been having a rough couple of days trying to figure this one out.
I'm having struggle creating a xy rotation - or an image "tilt" - on mouseover / mouse position on a movie clip (600 x 300). When the mouseover position is at the top left corner it should be rotated e.g. x = -50 and y = -50 (or "away from the mouse") and subsequently rotated x = 50 and y = 50 (still "away from the mouse") when the mouseover position is at the bottom right position.
check out the attached file. Don't ask me why, but I need that yellow rectangle to follow that grey dot, which rotates around randomly... but see, if you place the dot to the center left of the grey rectangle, you see that the yellow rectangle screws up. I've deducted that this happens for this reason: to the left of the grey rectangle, the rotation value is 178... 179... 180... then it jumps to -180... -179... -178... (you can try this out using an onEnterFrame function and tracing the rotation of an object that follows the mouse).
Since the yellow rectangle follows the grey dot with an ease, it doesn't just do: rectangle._rotation = dot._rotation But instead: rectangle._rotation += Math.round((dot._rotation-this._rotation)/rotatespeed) Some of you guys should already be familiar with this kind of movement, but it's usually used to move objects smoothly. The bug here is that whenever that dot randomly jumps up into -180 from it's original position at below 180, it screws up the yellow rectangle.
I'm trying to get a movieclip to constantly rotate either left or right. At first I set this._rotation=-1 Then I was thinking of using
if (this._rotation==1) {
this._rotation = -1;
But this only makes the object rotate 1 degree and then stop. How do I make it constantly rotate?
Trying to use an enterFrame event in conjunction with two functions that combined I want to move my object (a square) from the right to the left side of the screen and rotate it AROUND THE CENTER.When I use the following functions individually, they both work fine:

View 0 RepliesWhat I would like to have happen, is when the user drags arrow_mc, it will only rotate between 0 and 90 degrees. If you go above 90 degrees, and continue dragging, it will stop moving. The same would happen if you went below 0 degrees.Currently, the code below works, but you can go around in circles back and forth.Iwith figuring out how to constrain the drag rotation between specifid numbers, in degrees.

View 3 Repliesright now I have a code that rotates an object based on the position of it and the mouse. Thats all great but it sucks for a game, It is way too responsive. What I tried doing is making to rotation var:
[Code]...
after that I made rot2 the direct rotation between the object and the mouse: rot2 = Math.atan2(Ydiff, Xdiff) * 180/Math.PI; //(forgive me if this has spelling errors, as I am writing it //by hand right now) then I make rot effect the object: object.rotation = rot; now that the basics are set up I just need to make a code that compares rot2 and rot, if rot is less than rot2 it adds on to rot, if it is greater, then it will subtract.
(source at bottom) this all works well until you hit the most annoying part, the one i cant figure out how to fix.... basically there is a gap where the numbers go from 180 to -180, so the code flips out, reads this as it is supposed to, but this makes the object rotate a full 360 degrees around instead of just like 2 degrees to bridge the gap. If anyone has insight on this or thinks they might know what to do,

How can I get the X, Y, and rotation values, relative to the stage of a child of unknown number of parents?
What I am doing is: I have a 'stick' object, that creates a child 'stick', that creates a child 'stick', etc a random number of times.
The end stick then creates a leaf.
Each new stick rotates a little bit randomly.
As a result when my leaf falls off the final stick it flies off in a strange direction.
How can I get the leaf to fall down (eg y++ relative to stage)?
Alternatively I thought I could dispatch an event that has a leaf created at the stage level but then I really need to know what the X and Y co-ordinates of my final stick is realtive to the stage.
just need the code templet for moving an object in the direction it is angled at(the rotation)
View 3 RepliesI am tweeing a bunch of rectangles randomly on stage.
Code:
TweenLite.to(thumbArr[i],1,{
x:Math.random () * (stage.stageWidth - thumbArr[i].width),
y:Math.random () * (stage.stageHeight - thumbArr[i].height),
rotation: Math.random () * (60) - 30});
the problem is that after I added random rotation (between -30 and 30 degrees), the corners of my rectangles are still sticking out of the stage at the end of the tween.
If I trace objects width and height after the rotation I get the new values but this still doesnt help me because I am tweening to that rotation.
Code:
mc.rotation = 20;
trace(mc.width);
trace(mc.height);
How can I manipulate an object's rotation to ease in toward a specific rotation?[code]...

View 1 RepliesI got an object (called tempEnemy) which is flying around and shooting. The problem is that I can't keep the value tempEnemy.rotateTo positive, i.e. It shall be between 0 and 359 degrees. Currently rotateTo ranges from:
rotateTo < 0 (bug) && rotateTo > 0 && rotateTo > 359 (bug).
tempEnemy.dX = tempEnemy.destX - tempEnemy.x;
tempEnemy.dY = tempEnemy.destY - tempEnemy.y;
//I added 180 because my tempEnemy object was looking and shooting to the wrong direction
tempEnemy.rotateTo = (toDegrees(getRadians(tempEnemy.dX, tempEnemy.dY))) + 180;
if (tempEnemy.rotateTo > tempEnemy.frame + 180) tempEnemy.rotateTo -= 360;
if (tempEnemy.rotateTo < tempEnemy.frame - 180) tempEnemy.rotateTo += 360;
tempEnemy.incFrame = int((tempEnemy.rotateTo - tempEnemy.frame) / tempEnemy.rotateSpeed);

How to you calculate the total rotation of an object in either direction?
I need to end up with a number of total radinas(or degrees) that is posotive or negative depending which way the object was rotated.
Making a ship game because I am incredibly original.. With that aside, I have a problem. I have a function to fire bullets from my ship based on its rotation which works.. it uses this code on creation: ember ho jis ny mmujhe block kia hai
[Code]...
The above code is in my Ship class so I can easily make the bullets achieve the correct rotation. And to continually update its position, in the bullet's class:
x += Math.cos(rotation / 180 * Math.PI) * speed;
y += Math.sin(rotation / 180 * Math.PI) * speed;
So that all works well. But I have another class, EnemyBullet, which randomly generates and uses similar code to set its direction and movement. In my ship class:

I gather that the rotation is therefore always horizontal, but can't for the life of me see why? Can anyone give me an answer? Assuming it's simple enough because the code I used to setup the rotation is the same working code I have used to turn a movieclip towards the mouse..
Background: Sorry for the complex title, but can't think of a better way to describe this. So I have an image which is constantly moving and rotating (using matrix rotation around a specific point) on the stage. Problem: So I'm looking for a way that, when the user presses a button, a smaller image (exactly the same as the original one, only 3 times smaller) to position itself so that the smaller image's location is proportional to the the larger one's location. This means that the exact point of the larger image where it is rotating should be the corresponding part of the smaller image, thereby causing a kind of zoom out effect.
The truth is, I'm finding it even difficult to match just the x and y positions so they correspond, ignoring rotation, assuming the position is relative to the rotation point. Even this would be useful.
I am trying to use the Tween class to first rotate an object and then after the rotation is finished, use a new tween to move the object off the screen. Here is my code:

The trace runs, just as expected, right after the first Tween completes. But the second Tween doesn't work. What am I doing wrong?
