I have child (1) and I am rotating it by some custom num of degrees. After rotation (2) I want to 'align' this child to left_center side of the parent (should look like 3). Without roration I would set x to 0, but after rotation position of registation point changes.
way to calculate new x/y position based on rotation.
How can I calculate the next position of a "enemy" if know the positions x, y, rotation and speed?
View 1 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);
I am tweeing a bunch of rectangular shaped objects randomly on stage.

the problem is that after I added a random rotation between -30 & 30 degrees they still stick out of the stage a little.how could I calculate width & height of the these objects based on their final rotation so they dont stick out of the stage?
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.
I´d like to know if there´s a way to calculate by math the x position of point 1. There´s some coordinates at the image here attached. The "mc" movie clip is the main triangle.
View 5 Repliesimagen I have a movieclip (space_mc) w1000Xh1000 px?
inside the space_mc I have 2 movieclips:
- vlak1_mc (w100xh100px, _x:100,_y:100);
- vlak2_mc (w100xh100px, _x:400,_y:400);
ok!?
now i put the space_mc on the stage and scale it to 20% the stage (document properties) are w800xh600
Now i want that the USER clicks on vlak1,2_mc and the space_mc scales to 100% But the clicked vlak(1,2)_mc must have the exact coordinates as in the space_mc?
so if clicked on the vlak1_mc!
the space_mc zooms in to 100% and the _x,_y of the vlak1_mc are x100,y100 on the stage(800x600)?

How can i find line number in events like mouse clicked, key down and key up. And also highlight that line with color. I used TextArea.
View 1 RepliesI'm having a problem with a little movement script I wrote for a MC I have. I believe it either has to do with variable scoping, or with a coordinate system problem. (If I change the xPos and yPos in the onClipEvent (load) to 0,0...then the MC starts in the middle of the field (MC) I'm trying to move it inside of.) Basically...the ActionScript you see below is a part of the "Player" MC...who is supposed to move around a "field" MC I have.
I was assuming setting xPos and yPos to 0 would have the Player MC starting at the very top left of the entire screen...which instead it starts in the middle of the "field" MC.) Also - When I press the different arrow keys...the Player MC jumps around to different locations...but once at the new location the movement (in a single direction) works okay.

I have a circle wheel i want to rotate and the speed should be based on the mouse position. I also need to have easing in and out.
When the user hovers over the bottom of the circle it will begin to rotate one way and then th top of the circle would make it rotate the other way. The further to the top or bottom they are the quick it spins. It ideally needs to ease in and out when it starts and stops when the user moves the mouse away.
The circle will be the complete movie so 50% top and bottom each for each direction.
I'm trying to make a movieclip rotate around it's center (this is no problem since the center will never change). The problem that I am having is when I press the movieclip, in let's say the bottomright corner, and move the mouse the movieclip flips to a certain angle depending on my mouseposition. After the weird flip it works fine but it's the initial mouse click that makes the movieclip flip to an angle.I've tried playing around with different values to substract or add the starting angle but eveytime the result is not what i am looking for.Current code:

Essentially what I'm trying to do is nearly the same as this: http:[url].......However I'd like to ease/tween the movieclip position and rotation to the mouse position.The main issue I see is trying to get the current movieclip rotation and the target rotation,then tween it cockwise or counterclockwise from current to target.The way a movieclips rotation uses positive and negative numbers throws it off.If you just want to lock the mc rotation to the mouse rotation its fine, but once you try to tween it you run into difficulties. So the end effect would be like if you were to draw imaginary clockwise circles around the object, it should just keep rotating clockwise towards the mouse. Then if you started going counter clockwise it should just keep easing counter clockwise to the mouse.
View 1 RepliesI have created a globe that rotates with no problem, but what I am trying to do is to control the direction of the rotation based on the mouse position. For example, if the mouse is to the right of the globe, it rotates towards the right and if the mouse in on the left, the globe rotates left. When the mouse is over the globe, it should stop.

View 3 RepliesI want the diameter of the 'balls' orbit to change dependant on the position of the mouse but keep the point of rotation exactly the middle of the stage at all times.I.e. if the mouse is hovering over the exact center (both X+Y) of the stage then the 'ball' should have a tiny diameter of rotation (but contstantly follows the orbit in clockwise direction) whilst if you move the mouse towards the edge of the stage then the diameter of the orbit of the ball will increase.Here is the AS which controls a blank movieclip;

I have created a flash app in which there is a circle with circles plotted along it's circumference, it is rotated when the mouse is moved up or down. The rotation is drawn directly from the y position of the mouse pointer. What I would like to do is grade the movement some how so that the further down the mouse pointer goes the less impact on rotation the movement has.
My current code is like this:
myCircle.rotationZ = e.localY;
Is there some form of math formula I could use which would reduce the amount of rotation the greater the y position of the mouse position?
I have 2 container MovieClips (mc1, mc2), each of them has a separate x,y, rotation. I want to take a child from mc1 and addChild() it to mc2 while keeping the same x, y, and rotation on the screen so you see the added child mc as if it didnt change position or rotation, just moved to the other MC.

I've got two concentric circles with their centers at (centerX,centerY). The inner circle has a radius of 100 and the outer circle has a radius of 400. If take a point on the circumference of the inner circle, I can draw a line from the center to that point. Let's call that point x1,y1). I now want to continue that radius out to the outer concentric circle and calculate the position of that outer point (x2,y2).
I'm adding a 3px 'dot' just to show where x1, y1 is on the screen. (Subquestion: I can't see it...not sure why.)This is what I'm trying:
var x1:Number = 100;
var y1:Number = 50;

I have a clip that rotates to orient itself towards the mouse when the mouse is over a given area. When the mouse leaves the area, the clip snaps back to its original position.
1) the clip snaps directly towards the mouse at the moment the mouse enters the clip; I would like it to actually rotate;
2) the clip snaps directly back to its original position when the mouse leaves the clip; I would like it to ease back into position.

I have a movieclip and when I do 3D rotation from Transform panel, It rotates perfect, center is in the middle of image, and when I apply mc.rotationY, rotation center is in left of the image, aren't 3D rotation from Transform panel and mc.rotationY from AS same? what's up?
View 2 RepliesI'm trying to do some augmented reality projects with flartoolkit . I can now put simple 3d objects on my marker and it works fine , but I wanna give my project some events that the user can interact with. I'm trying to trace the rotation of the marker. there's a container:DisplayObject3D which my application uses to add the 3d objects , I traced this :"trace(container.rotationZ)" but it's just returning 0 . I studied another AR application's source code and it was using the rotation of it's container object without problem .and I think I should mention that I'm using the exercise file of seb lee delisle papervision3d course from [URL]. anyone has any experience with flartoolkit? the main functions of my my code is as below:

Is it possible to have the child movieclip rotate separate of the rotation properties assigned to the parent? so ultimately giving the child element it's own axis?I've customized Lee Brimelows (gotoandlearn.com) 3D carousel to spin on the x axis to make it a vertical carousel. I've also rotated that by 45 degrees on the y axis to see all the items, and wrote a snippet of code to hide the left portion of the carousel. The entire carousel is contained within the 'container' movieclip, and inside of that are my carousel items (as seen below), with the larger item being the item in focus.
On rollover of the item in focus, I want to rotate it so it faces the viewer (as seen below),basically removing the 45 degree rotation applied to the container.The problem i'm running into is when you rotate the container (changing the rotationX of the container), the axis basically rotates with it, so when i rollover the next item 'in focus', the following happens..(in the example where it appears how it want it to, the carousel is at a rotationX of 0, so it works fine)
Program A has a cannon that aims to line up with where-ever the mouse is pointing, in 360 degrees, and fires when the mouse is is clicked. Program B has an eye instead of a cannon that should in theory do similar functions when the capslock key is toggled, but instead only has a 90 degree range of motion from the Right of the eye toward the bottom (quadrant 4 only). Where did the ther 270 degrees of rotation disappear to?

View 1 RepliesI am trying to do a simple "pseudo 3D" rotation of a movie clip. The clip would "flip" on to the screen. I have created the effect using PaperVision3D, however, the final SWF is about 64k and my project requires a smaller file size. I tried to create the flip effect manually by creating skewed versions of the clip and tweening between them, except this doesn't work because the shape is not tweaked along the vanishing point as it should be. It looks like perhaps I could accomplish what I want to do using the MatrixTransformer but I've not had much luck so far.
