ActionScript 2.0 :: Random Rotation Around A Fixed (Central) Point
Jan 15, 2009
I have a project on the go which has a compass that I would like to have move randomly around a fixed central point (giving the idea of changing direction).Would anyone be able to help me out with the coding to get this to work?
As in the figure i have three lines out of which line1 and line2 are fixed. line3 is derived from line1 based on some angle say 70.I try to rotate the line3 but it deviate from the point x1 and x2. I try the code like this
I have four objects that when clicked needed to programatically arch back to one central point. at the moment I cna easily have them travel in a straight line, but I need all of them to rise a little (20px) as they travel to the left then drop to that centralized point.
i dont know the math to have a mc rotate around a central point by constricting to an arc..i have a circle and i want a mc to follow around the edge depending on the mouse position relative to the center of the circle...
One of the strangest things I've EVER seen with any software. I teach Animation at a high school. I had my students do the following, using Flash CS4, on Windows XP SP3, with Flash 10 installed. All software latest as of April 2010.
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
Is it possible that I can have a fixed 3d rotation center for a movieclip.So if I have two movieclips spaced apart and I have rotated them, they rotate in their own axis rather than based on a single axis.
I posted a while back looking for a function to make one movieClip circle around a fixed point. The solution I was given (which has worked perfectly up until now) is:[code]This function is called repeatedly by a Timer (loopTimer) with delay 10.The problem I have hit now though, is that if I want to modify or reverse the speed of rotation at any point it causes a jump in position (because I am setting the x and y values directly, rather than incrementing them e.g. "x = ..." rather than "x += ..."). Can anyone see a way to modify this function so that I can just increment the x/y positions?
This is one of the threads that was deleted. I've come up with the same problem: how do you go about dragging an object around a fixed point (rotation)?
I can do a normal drag & drop, but with this i don't even know where to start
I followed some of the tutorials about random movement, but I couldn't find where I was looking for! I'm looking for a random movement only on the _x axis with fixed values. I will explain myself a little better. I have 10 pictures (120 x 120 pxl) with above that a transparant mask (120 x 120 pxl) I want the mask to move randomely over the pictures but so that the mask completely cover a pictures so the random movements should be a all cases a plural from 120, wich means (120, 240, 360, 480 etc)
I have created a movie clip which contains a bubble inside it which floats upwards. On my main banner i want this symbol to appear randomly (time and location) but at the same height measurement everytime, but a random width value.
Flash knows where the anchor point is in 3D space in order for the symbol to rotate around it, but I can't seem to figure out how to see the coordinates of the anchor point or type in new ones. Please tell me how to do this. I am already very annoyed that Lynda, a pay service, doesn't think this is vital information. Apparently they think we would never want to do anything more visually stimulating than one simple spinning logo! But I digress...
Just to be clear, I know how to move the anchor point visually on the stage, but I want accuracy. I want to be able to give two symbols the exact same coordinates to rotate around.
i'm working on a flash game at the moment, and i would like to know if i am able to set the point that the movieclip rotates around using actionscript.
i don't want to do it by simply moving all of the contents of the movieclip closer or nearer. is there any other way of doing it? i couldn't find any simple functions for it. am i just going to have to use some complicated maths?
[edit] rotation point, aka, registration point.[/edit]
I am making a 'simple' template builder in flash which allows the user to add/remove text boxes and images to the stage. I can rotate any of the movieClips fine but it rotates from the top left and i want it to rotate from midpoint. Is there a way to set the midpoint/rotation point using actionscript?
I have the following problem. I have an MovieClip in a holder MC. I would like to turn the inner MC X with 'rotation' parameter, and still keep it in the holder mc to the right and bottom of the holder MC reference point. So after turning it should look like thatanyone can tell me how to do that? Basically a function that takes any X rotated in any degrees through X.rotation = ... and puts it back in place in the holder MC.
Has anyone got a bit of code I can use to change the center point DisplayObjects rotate around in a 3D space? I need it to work with rotationX, rotationY and rotationZ. I know theres a workaround of wrapping every object in aother sprite and offsetting the x & y positions but I'd much prefer a math solution. As an example of the problem, this code should make a star shape:
I'm attempting to write a racing game. I've loaded in my image, I brought it to the stage and now, all I want to do is rotate it from its' center and not upper left corner.
The code:
racer.rotation += 5;
rotates from the upper left corner. How do I rotate from the center of the car/sprite? I've tried putting it into a container but I'm unsure on the coordinates of the container because I tried to set the x,y coordinates to half the sprite image but y'know, it's not doing what I expect it to.
ActionScript Code: if (arrowLeft) { var container:Sprite = new Sprite();
[Code]....
I will never sneer at another racing game! I didn't think it would be this hard to do a simple rotate of an image!
I am rotating some objects which their rotation (pivot) point is not at the center. My aim is to rotate from the center of the shape. How can I overcome this?
greetings, first of all sorry for my english. This question will probably looks more difficult than it is.
I have movieclip which I want to rotate around internal point few angles with click on certain button, and I manage to do it, but I want to see motion, or even put ease not only to immediately pop up in the place.
I am creating a a small site with a spinning menu but I want it to spin only in onedirection ( clockwise) and around the centre of the 3 point cross I am using as a menu.I have this currently to rotate the menu but I want it to only rotate on way and around centre.
Code: content_mc.draw_btn.addEventListener(MouseEvent.CLICK,drawClick); function drawClick(e:MouseEvent):void{
I want to have arm movement such as the forearm rotating about the arm where the elbow should be the problem is the registration point is at the shoulder for arm. I want the forearms registration to be constantly equal to a simulated registration point where the elbow should be as the arms registration point would be at the shoulder. I need to do it without nesting (a movieclip within another) is it possible. I tried using a constant distant between the two clips but it doesn't work. Don't know I have to use trigonometry or not
I think in brief what I trying to accomplish is onEnterFrame=function(){ arm._x=shoulder._x arm._y=shoulder._y arm._x=simulated_x (where elbow would be) arm._y=simulated_y (where elbow would be) }
I am trying to rotate a symbol about the y-axis, 45 degrees one direction, then back to center, then 45 degrees the other direction. Seems like a relatively simple task, except here is what happens.
Here is the object with no rotation: Here is the object rotated exactly 45 degrees: And here is the object rotated exactly -45 degrees:
I need the object to rotate the same as it did the first time but in reverse, otherwise "45" and "-45" are generally worthless numbers to refer to. Is it something to do with the pivot point? I made sure the registration point was in the center when I created the symbol. It doesn't seem to be pivoting the object around the center though. How do I rotate about the y-axis using a pivot point that is actually in the center and gives the same (but opposite) effect when rotating it one way versus the other?
var shape1:Shape; shape1=draw(); addChild(shape1); shape1.rotation=50;
[Code]....
Then I want to rotate the shape at it's center point(200,202) by using shape1.rotation=50,but I find the shape don't rotate at the the center of it's shape. How to realize the function which make shape rotate at its center point?
I'm trying to convert a Sprite that I have into BitmapData so I can perform some collision detection. There are a few things about the way the Sprites are used that is making this more difficult than I expected:
The Sprite itself is a container which holds another Sprite that actually has a box drawn in it. The inner Sprite is positioned negative half its width & height so that it can be rotated from the center via the container. The container may be rotated at any angle at any given time
So my approach thus far has been attempting to draw the outer Sprite onto a new BitmapData object with a Matrix to account for the difference. Whilst I can use a Matrix to make this work for one particular rotation angle, I cannot find a way to make it work for any rotation.
Here's what I'm doing to draw onto the new BitmapData:
var p:Product = getProduct(); // Product is the container with the inner sprite var bounds:Rectangle = p.getBounds(stage); var bd:BitmapData = new BitmapData(bounds.width, bounds.height, true, 0x00FFFFFF);
[Code]....
Translating by the same amount as the previous example will no longer work here, and the box will still be cut off. I've looked around at some solutions posted before or suggestions from other people but they don't seem to work for me due to my container Sprite and rotation.
how I can count the B point's coordinates (see attached image... or not as I am a new user...pf!). I know the arrow's rotation - so the angle (let's say it is -120), A's coordinates (0, 0) - A is the middle point of the arrow, and that the distance between A and B is 50 px.
