• Access a movieclip in a native from class

  OK, so I find the classes all about confusion, but take a look at this example. A movieclip is created following the cursor, but it is created as a class. http://asgamer.com/2009/AS3-characte...se-with-easing What should I put in the normal timeline of the MouseControlled.fla file to target the character who moves around? As if I wanted to start coding some objects, it could hit that I have on the native timeline of root how to reference it? What is the path to the instance name?

  You can adapt an example of the timeline class by removing the package, the removal of the line of the class line, remove the "Builder" of opening and the deletion of the words "private" or "public". Also remove all brackets very closed at the end of the script and the end hence is the constructor function.

  In the case of this example, there is a line you have to add something, which is that contains the reference of the scene. Or you can replace this variable "step-by-step." In my version below I put just step in this variable.

  So, make a new movieclip on your stage of FLA, go into the movieclip and put this script under 1 timeline, then do a test movie:

  import flash.display.MovieClip;

  import flash.events. *;

  import flash.display.Stage;

  var stageRef:Stage = stage;

  var speed: Number = 10;

  x = stageRef.stageWidth / 2;

  y = stageRef.stageHeight / 2;

  this.stageRef = stageRef;

  addEventListener (Event.ENTER_FRAME, loop, false, 0, true);

  function loop(e:Event):void {}

  var yDistance:Number = stageRef.mouseY - y;

  var xDistance:Number = stageRef.mouseX - x;

  If (Math.sqrt (yDistanceyDistance + xDistancexDistance)< speed)="">

  x = stageRef.mouseX;

  y = stageRef.mouseY;

  } else {}

  var radians: Number = Math.atan2 (yDistance, xDistance);

  x += Math.cos (radian) * speed;

  y += Math.sin (radian) * speed;

  rotation = radians * 180 / Math.PI;

• gravitating round an object in motion

  Hi, I had a mc to circle around another mc (which is called a) which you can move

  It is on the mc dragiable this name mc's (a)

  on {(press)
  startDrag (this, false, 0, 23, 495, 407);

• example of blocking software signal in C++

  Hello

  I am new to the NC and data acquisition. Just posted this question before http://forums.ni.com/t5/Signal-Conditioning/usb-6211-DAQ-frequency-question/td-p/3202422and discovered that the signal cannot be locked on a hardware level.

  Can anyone provide an example in C / C++ to lock a 400 hz signal. I used the example of ContAcq - IntClk.c to read the data of a resolver (Sindh and cosine) and a reference signal. However as the signal moves to the right (in this case) it becomes difficult to determine the position of the resolver.

  Thank you in advance.

• SetWorldTransform does not work on the actual printer

  It is a question of impression MFC Device Context.
  I need to print-90 degree rotated out of printer. I developed the following code using SetWorldTransform. The problem is that it does not turn the contents of the physical printer device context. BUT... If I save printing in printer output (.xps) file, it records and displays the content of the context of device-90 degrees correctly.

  void CMyDLL::drawReport (CDC * pDC, CPrintInfo * pInfo, bool bRotatePage)
  {
  int nGraphicsMode;
  float fWidth;
  float fHeight;
   
  bool bIsPrinting is pDC-> IsPrinting();. Just to test. This returns true.

  My drawings on the device context are here

  You have a periodic function, the OnEnterFrame function, which is called over and over again. In this function, you have a hitTest for an object whose value is stored in a variable, boss1. When you remove Boss1, the value is stored in the variable boss1, the variable has no value or reference, and so the hitTestFunction generates an error. He has nothing to work with.

  So, if you take the value stored in boss1, you need to either stop the execution of the OnEnterFrame function or you will have to work around the section of the function that performs the hit test.

• Follower of the mouse of rotation with easing

  I'm terrible at math and having a problem to reach my goal.

  http://www.newgrounds.com/dump/item/6e5cde6c6b94de74119aac82c43312d2 - example

  It works just fine, but what I want to do is have each object to follow the rotation at different speeds. I want that every MC having "Acceleration".

  I can't understand how to run a little slower than the mouse itself. As a result, just dead on, same speed as the mouse moves, it moves.

  Related to mcMouseFollower.as MovieClip class.

  I have my main class the following:

  package {}

  import flash.display. *;

  import flash.events.Event;

  SerializableAttribute public class MAIN extends MovieClip {}

  public var follower: mcMouseFollower;

  public void MAIN () {}

  the constructor code

  Tracker = new mcMouseFollower();

  Follower.x = stage.stageWidth / 2;

  Follower.y = stage.stageHeight / 2;

  stage.addChild (follower);

  stage.addEventListener (Event.ENTER_FRAME, frameLoop);

  }

  public function frameLoop (event: Event): void {}

  Check out the coordinates of the mouse to discover the angle

  var cy:Number = stage.mouseY - follower.y;

  var cx:Number = stage.mouseX - follower.x;

  var Radians: Number = Math.atan2 (cx, cy); / / Find the angle

  var degrees: Number = Radians * 180 / Math.PI;// convert to degrees of rotation

  Rotate

  Follower.rotation = degrees;

  }

  }

  }

  To do this manually, you need to find the change in rotation between the follower.rotation and the degrees of calculated. Then, you apply some of this difference. So if you want to have the rotation of the rod move 1/10 of the path to the destination of your choice each image, calculate the change in the rotation needed to point to the mouse, then multiply by 0.1 and apply this rotation changed to follower.rotation. This does not exactly work as tweens that you configure in Flash because it will not have an exact end time. Instead, each image rotation reduces the difference in new rotation of half. It will resemble an ease of exit. You can check when it is thin enough (for example, the difference is less than 1 degree) and just snap to your final rotation rather than continue to settle for halfway.

  You'll want to know how to work the degrees of rotation. Pointing to the right is 0 degrees, rotation to the right there is positive, go to 180 that points to the left. From 0 degrees and rotating timer causes the downward rotation value, entering negative numbers, from 0 to-180 (pointing to the left). So when you try to interpolate a value through the left direction you have a problem, since the numbers of jump from-180 to 180 at that time here.

  To solve this * West * problem, you detect if the rotation must be changed by more than 180 and you adjust accordingly for the direction of rotation moves the shortest distance to the rotation of the target rather than the long way around. The calculation in the SmartRotationPlugin of the packaging of GTween is a good way to handle this:

  https://code.Google.com/p/Pipoca/source/browse/trunk/classes/com/gskinner/motion/plugins/S martRotationPlugin.as? r = 9

  Here's the corrected code (starting after your calculation of degrees):

  var deltaDegrees:Number = degrees - follower.rotation;

  deltaDegrees % = 360;

  If (deltaDegrees > 180)

  {

  deltaDegrees-= 360;

  }

  ElseIf (deltaDegrees<>

  {

  deltaDegrees += 360;

  }

  Rotate

  Follower.rotation = degrees;

  Follower.rotation += deltaDegrees * 0.1;

  You can also consider using a tween as GTween for your tween engine: http://www.gskinner.com/libraries/gtween/

• Limitation of DISTANCE to two decimal places

  I pretty much get the Google Maps API, talking to my SQL database. For the results of my research, I have SQL code:

  SELECT *, (3959 * acos (cos (radians (".")))) $POST ["latitude"]. (radians (lat)))) * cos * cos ((LNG) radians: radians (".")) $POST ["longitude"]. ")) + sin (radians (". "))" $_POST ["latitude"]. ")) * sin (radians (lat))) AS distance FROM VenuesGeocodes1 HAVING distance < 100 ORDER BY LIMIT 0, 30;"

  That works very well, but will display the distance to 15 decimal places, which is an exaggeration full.

  How can I limit that to only two decimal places? I thought I just needed to change the distance to distance (10.2), but he doesn't like it.

  If anyone can let me know what need would be much appreciated.

  Thank you.

  If you use PHP, you can do it like this:

  $grandtotal = number_format($grandtotal,2,'.',',');

• Synchronization of gyroscope problem!

  I managed to have a sample of work using the native extension of Gyroscope. I followed the following steps:

  (1) download the extension

  (2) added the DONKEY file on the library path in Flash Professional CS 5.5

  (3) coded as described in the documentation for the extensions

  (4) exported the SWF file

  (5) compiled the SWF and the extension using ADT

  I worked perfectly. I had a turned 3D cube using gyroscope data.

  Well, not exactly calibrated because after awhile app seems to have lost direction.

  But I read this is normal and you had to use the accelerator to balance it.

  I'm not worried about it even if right now.

  (6) and then I added a video DisplayObject that is attached to the camera because I need to make a game of AR.

  When I test this gyroscope data seems out of sync with the reality of the time lapse (i.e. made rotations appear seconds after)

  and this gets worse and worse when the time elapses. Perhaps the video makes gyro data for synchronization.

  Do you have an idea how overcome this problem.

  I don't know, so I can't fix it myself with the data source Objective C code.

  If you can help my kid would be great, I have a presentation demonstration Friday of this week.

  Thank you

  Nobody answered so... for those interested in the problem:

  (1) when the device is set on high rates resolution produces this Gyroscope GAL.

  (2) resolved this lower resolution 480 x 288 to 15 images/s

  This on an iPad 2, maybe it depends on memory and other things so can not work for iPad 1 or others.

  (3) could not use StageVideo. It seems that he can play only local or videos server but no camera! Adobe help please add this in the future.

  Here you have a test code to find that what I have worte in this forum is real:

  package  {

  The code simply creates a square shape to see visually gyroscopic rotation

  A TextField to print the values of gyroscopic rotation Y

  And an event to listening to a single CLICK anywhere on the screen to activate the camera

  and show the video. Try several values for the dimensions of the camera and you will see

  only small (480 x 288 to 15 images/s) values will not add the question of FDA/off-synch

  Once you run the app try clicking anywhere on the screen and

  Video if poster and you will see the gyro values will come much later.

• Figure out how to bug

  So, I understand that I can toggle the Debug button. And that is supposed to help me.
  
  But, I feel as if there is a reference to the fact that I don't get.
  
  For example, the error message says: line 7, column 1
  Who wants to help me?
  Is the column 1 column 1 on my page?
  And 7th referring to article 7?
  
  And, what is the trick to write longer formulas? The window is so small, I can't get a handle on my formula... you write in a text editor and copy and paste?
  
  Thank you
  Marion, back to my case of nesting.

  Marion,

  The error's message refers to the line 7 of the code you are running begins at column 1 of this line.

  I write, test and debug most of my code (PL/SQL and SQL) outside at the APEX and you recommend you do the same. SQL Developer is a good choice and your formatting code, long forms will be easier to read and debug.

• Math.COS, Math.sin = Math.HELP

  Hi all

  I was hoping to create a JS script to move objects from the common center based on their current location. I thought to use an element of single selected path as the center based on its position x / y and width/height. Using this reference point that the script would then move away all other elements of the path of this central point based on a desired amount and with uniform increases, account required to their current location of this Center. I was thinking about cos and sin would be my friend in this case, but they seem to have become my enemy instead. ;-)

  Does this sound feasible? What Miss me, hurt, misinterpretation? Here's an attempt at non-working, I can't fix things, maybe I was close and missed or maybe I am so far and its complex more than I thought. However at this point I'm confused through my various attempts which is only one of them.

  Thanks in advance for any help and health mental someone can provide.

  // Example failed code, nonworking concept
  var docID = app.activeDocument;
  var s0 = docID.selection[0];
  pID = docID.pathItems;
  var xn, yn;
  var stepNum = 20;
  for (var i = 0; i < pID.length; i++) {
      var p = pID[i];
      var dx = ((s0.position[0] + s0.width) / 2 - (p.position[0] + p.width) / 2);
      var dy = ((s0.position[1] + s0.height) / 2 - (p.position[1] + p.height) / 2);
      xn = Math.cos(Number(dx) * Math.PI / 180)+stepNum;
      yn = Math.sin(Number(dy) * Math.PI / 180)+stepNum;
      var moveMatrix = app.getTranslationMatrix(xn, yn);
      p.transform(moveMatrix);
      stepNum+=stepNum;
  }
  

  Hi W_J_T, here's a way to do what I think you want to do, I put comment the increment so everything will "explode" the same distance, do not know if it is you need.

  first of all, I suggest the calculation of the center of the object selected out of the loop, you only need to do the math once.

  In addition, (s0.position[0] + s0.width) / 2 has a problem, it will not give you the Center, check below

  // calculate Selection center position
  var cx = s0.position[0] + s0.width/2;
  var cy = s0.position[1] + s0.height/2;
  

  then we're going to loop through all the elements and calculate their Center

          // calculate pathItem's center position
          var px = p.position[0] + p.width/2;
          var py = p.position[1] + p.height/2;
  

  We will pass the calculation of the distance from the center of the selection in the center of each item, we don't need this method, other methods may use this information.

  now, your real question on Sin / Cos

  xn = Math.cos(Number(dx) * Math.PI / 180)+stepNum;

  Sin (angle) and cos (angle) expect angles in Radians, you not provide any angle in the formula above. We need calculate the angle between the selection and each path Center

          // get the angle formed between selection's center and current path's center
          var angle = get2pointAngle ([cx,cy], [px,py]);
  

  as soon as we have the angle we can apply to our variable 'Explosion', I guess is stepNum and get its x and is distance he needs to walk away selection

          // the distance to move is "stepNum" in the same direction as the angle found previously, get x and y vectors
          var dx = stepNum*Math.cos(angle);// distance x
          var dy = stepNum*Math.sin(angle);// distance y
  

  everything remains to be done is to move the paths, here is the whole thing

  // Explosion, AKA move all items away from selection
  // carlos canto
  // http://forums.adobe.com/thread/1382853?tstart=0
  
  var docID = app.activeDocument;
  var s0 = docID.selection[0];
  pID = docID.pathItems;
  
  var stepNum = 20; // this is the distance to "explode"
  
  // calculate Selection center position
  var cx = s0.position[0] + s0.width/2;
  var cy = s0.position[1] + s0.height/2;
  
  for (var i = 0; i < pID.length; i++) {
      var p = pID[i];
  
      // skip selected item
      if (!p.selected) {
          // calculate pathItem's center position
          var px = p.position[0] + p.width/2;
          var py = p.position[1] + p.height/2;
  
          // get the angle formed between selection's center and current path's center
          var angle = get2pointAngle ([cx,cy], [px,py]);
  
          // the distance to move is "stepNum" in the same direction as the angle found previously, get x and y vectors
          var dx = stepNum*Math.cos(angle);// distance x
          var dy = stepNum*Math.sin(angle);// distance y
  
          var moveMatrix = app.getTranslationMatrix(dx, dy);
          p.transform(moveMatrix);
          //stepNum+=stepNum;
      }
  }
  
  // return the angle from p1 to p2 in Radians. p1 is the origin, p2 rotates around p1
  function get2pointAngle(p1, p2) {
      var angl = Math.atan2(p2[1] - p1[1], p2[0] - p1[0]);
      if (angl<0) {   // atan2 returns angles from 0 to Pi, if angle is negative it means is over 180 deg or over Pi, add 360 deg or 2Pi, to get the absolute Positive angle from 0-360 deg
          angl = angl + 2*Math.PI;
      }
    return angl;
  }
