I have a rotation value in degrees(0-360) and a value for magnitude, ie (1-10 pixels per second).
How to apply this information to determine what to add to an objects x and y values to send the object off in a given direction at a given speed ?
I'm working on an interactive animation for a university assignment. Here in this scene the user is able to turn a safe dial left and right either using on screen buttons or keyboard keys. The trouble I'm having is trying to write an IF statement to detect the angle of the safe dial so when the dial == an angle of rotation the scene goes on to play the next frame of the animation.
Code:
import flash.events.MouseEvent;
import flash.events.KeyboardEvent;

View 1 Repliesi'm trying to work out how to get a movieclip (of an arrow) to rotate then move in the direction it is pointing, controlled using the keyboard. Below is the code i have written so far, I can't get it to move in the correct direction. I also can't get it to keep moving after only one key press.
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressDown);var stageW:uint=stage.stageWidth;var stageH:uint=stage.stageHeight;
var speed:Number = 5;

i'm using the an actionscript for random movement that i found here... [URL] but my problem is that i need the object to flip horizontally depending on the direction it is moving... the object that is moving around is a bug, and i need it to face left if it's moving left or face right if it's moving right.
View 1 RepliesI recently installed Flash CS4. As I attempt to learn from different tutorials I've run into a problem I can't figure out. I've watched the video tutorial at: [URL] several times to try to emulate the rotating logo. The problem I run into is when he says to open the Motion Editor and to edit the Rotation Y and Rotation Z properties. When I open my Motion Editor there is no Rotation Y or Rotation X. There is only a Rotation Z property. I've played it over and over to try to discover what setting I've missed but don't see it. How do I see a Rotation Y property to be able to edit it?
View 2 RepliesI know 3D rotation is well documented on SO and many other sites, but despite reading countless explanations I still haven't figured out where I'm going wrong. My background is in art and design, not math and programming, and I'm never really certain if my angle of attack (no pun intended) is the right one. Rather than paste a patchwork of my dismal code, I'm including an image describing my problem. What I'd really like is a step-by-step worded breakdown of how to solve it. Pseudo code is useful, but I will learn more if someone will just aim me in the right direction or point out common pitfalls.

I'm using flash CS4 and I'm trying to create a motion tween with a rotation (several actually) and every once and a while Flash decides to screw up my tween and I don't know how to fix it. So i have an arm(symbol) with the rotation point set at the elbow... after I've already moved it and rotated it a few times without an issue, I try to rotate it about 20 degrees and all of the sudden my arm is randomly doing a 360 degree spin. I can't seem to fix this!

View 3 RepliesI have a stage with and height of :600x400 On this stage i have 3 squares that have a centerpoint in the middle. The square are 90 (width) and 80 (height)The first square is aligned to the left site and the second one in the middle and the third one on the right The perspectiveProjection is setup using the middle of the stage as it projectionCenter.When i rotate all squares to 90 degrees (rotationY) than only the middle one is now not visible anymore, at that point i want to switch the image inside the square. But at 90 degrees the left and right squares are not invisible.. For the left square that point wouldbe at 90 - 22, and the right one 90 + 22. Is there a way to calculate the correction value (22) in this example?
What i don't want is to give every square it's own perspectiveProjecten , then it would work but you have a completely different3D rotation.The only thing that goes wrong in my example is that the image from the left and right square are not changed at the right time, because 90 degrees on the left square does not mean it it not visible at that point.
And here is the code:
import flash.display.MovieClip;import flash.geom.Point;import flash.geom.PerspectiveProjection;import fl.transitions.*;import fl.transitions.easing.*
var squares:Array = [c1, c2, c3];

I have a MC(a small army tank) that I can rotate using the right and left buttons. I want to make it move forward when I push the up arrow - The Catch . . . I want it to move in the same direction it is currently rotated. Example: I rotate the tank 10 degrees and then I push the up arrow off it goes in that direction.
View 2 RepliesI need to move a movieclip dynamically over a path. The movieclip has a front which should remain pointing to front when moving along the path. So I need an angle at which the movieclip should be rotated regularly. This is something similar to the motion guide we have in Flash.

I'm having a bit of a problem with my script. I currently have a square that moves across the screen. There is another square on the stage as well. I want the other square to call a hitTest with the first square (that moves), which we'll give an instance of "hero". The hitTest should make the "hero" (or first square) rotation a specific degree (in this case 30) and then move him in a specific direction, either up, or down the y-axis or left or right on the x-axis. This is my current code, attached to my second square.
onClipEvent(enterFrame){
if(this.hitTest(_root.hero)){
_root.hero.rotate += 30;

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.
View 1 RepliesI want to make a movieclip moves smoothly and when it changes the direction, it can turn smoothly but not a sudden turn, I try out the code below. and the truning is odd:

I am very new to flash, I got a player, and the idea is for a top down shooter kind of thing, I got the player to rotate with left and right, and its rotation equals its direction, now how can I make it move forward in its current direction when I press up?

View 1 RepliesI'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.
What i need to do for my assignment is to get a Collada character head to detect movement through a web camera and rotate on its y axis.The Collada character will only turn when the movement is detected and when it gets to a certain point in its rotation then the game is over. When no movement is detected then the Collada character will have to turn back to its starting position.I want to make a min rotation variable of 0 and a max variable of 180 degrees.I have successfully added a basic collada image into my scene and it rotates on its y axis.

I'm trying to access the rotationY property in code to determine the current state of a movie clip that has its rotationY animated in the motion editor. What I'm seeing is that the value of the property reported in a trace stmt is different than the value shown in the motion editor.
In the motion editor I created a tween from rotationY=0 at frame 0 to rotationY=353 at the last frame. I've added the attached code to get the value of rotationY at every frame.
What I see is that the rotation does not increase steadily from 0 to 353. Instead it increases from 0 to 90 and then decreases back to 0 and then goes negative to -90 at which point the absolute values decrease toward 0. This seems like a bug. The rotation of the object is visibly different during the 0 to 90 deg
Is there a way to prevent a motion tween w/ rotation from dropping on the Y axis? Basically I used Free Transform to change the angle of a line, but it always lowers itself on the Y axis when I insert a motion tween in it.

View 0 RepliesI have a circle: Width 530 and height 800. I want an object to follow this circle using a motion path, but you cant do that in pure actionscript, so I tried rotating the circle with the object attached, but warping the circle at the same time... so width becomes 530 and height becomes 800... but because the circle has rotated at the same time, it looks like it hasn't moved - except for the object attached.
ActionScript Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var Tween1:Tween = new Tween(circle,"width",None.easeNone,800,530,2,true);
var Tween2:Tween = new Tween(circle,"height",None.easeNone,530,800,2,true);
var myTween:Tween = new Tween(circle,"rotation",None.easeNone,0,180,2,true);
This was the closest... but it still dances around the page before anything happens.... and it isn't reading the sizes properly? 530 isn't 530, but something bigger, and 800 is actually smaller?
I want to apply a motion blur to the rotation of a movie clip. I am currently rotating the movie clip 540 degrees via actionscript using the tween class below:

import mx.transitions.Tween;
import mx.transitions.easing.*;
var targetRotate:Tween = new Tween(_root.target_mc, "_rotation", Regular.easeInOut, 0, 540, 3, true);

This seems to be a good start, but I need to change it to apply to the _rotation of my movie clip. Lets say for the sake of argument, my movie clip has an instance name of target_mc as well.
