ActionScript 3.0 :: Manipulating A Circle, Using Two Transformation Matrices?

Aug 31, 2011

I am having trouble with some code, I am trying to get a circle to rotate around a center point, as well as rotate in a circle. at the same speed as its parent circle. however I am having some trouble, and I know it is from how I am transforming the position of its matrix, however I honestly can not find the mistake. below is the code:

ActionScript Code:
import flash.display.Sprite;
import flash.geom.Matrix;
var outcirc: Sprite= new Sprite();

ActionScript 2.0 :: BitmapData And Transformation Matrices - Shift The Newly Created Bitmap?

Jan 29, 2007

I've started getting to grips with using the BitmapData class and a Transformation Matrix in the hope that I can start making some interesting image effects. However, at the moment Im having trouble figuring out how to shift the newly created bitmap so that any scale transformations are applied from the center rather than the top left corner. See here for example: [URL] The flower on the left is the original, the flower on the right is the new image created using "bitmapData.draw()". It has been scaled up to twice the size, but I want this to happen from the center of the image.

Flash 9 :: Reset Transformation Point/Set Transformation Point?

Feb 8, 2008

When I right-click a symbol the options "set transformation point" and "reset transformation point" come up. They don't seem to do anything for me. I thought it would center them or something. This is not the case. I have the white transformation point in one corner in one keyframe and a different corner in another keyframe I click "reset transformation point" on both frames and they don't move.

Flash - Multiple A Vertex By Two Matrices?

Mar 28, 2011

I'm trying to understand molehill and would like to multiple a vertex by two matrices, say:

output = theVertex * scaleMatrix * rotationMatrix

Im guessing my vertex shader would look something like:

"m44 vt0, va0, vc0
" +
"mul op, vt0, vc1
";

And i would set the matrices with

context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 0, scaleMatrix);
context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 1, rotationMatrix);

But its not working.Im aware that i could multiple the matrix before putting on the shader, but i am trying to understand AGAL.

C# :: Collection Of Various Color Matrices For Bitmap Manipulation?

Feb 6, 2011

I've been messing around a bit with some low-level bitmap manipulation and having been creating some various color matrices to apply to bitmap data to add "filters" (for lack of a better term).I have seen a number of tutorials online in C# and AS3 about applying various color matrices to bitmaps, but was curious if anyone simply had a collection of these color matrices that map to specific filter styles (black and white, sepia, etc.).

ActionScript 3.0 :: Collision Detection - Rotation And Matrices

Nov 23, 2009

I am using Corey Oneil's collision detection kit, but I am having a problem with rotation. In my code I have:
myItem.rotationY = 180;

However, during a collision detection, having it rotated like this causes an error with this line:
transMatrix1.concat(currentObj.parent.transform.ma trix);
The error is simply "Error #1009: Cannot access a property or method of a null object reference."

I have not really worked with matrices and rotation. Do I need to make a matrix rather than just doing the rotationY or should I change something else? I cannot manually change the movie clip because it throws off the animation and armatures.

ActionScript 2.0 :: Calculate The Direction And Speed A Circle Has After Colliding With A Static (non-moving) Circle?

Mar 8, 2005

I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision

If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?

Actionscript 3 :: Change Shape Of Circle By Dragging Point On Circle

Mar 16, 2012

I want to create circle, and put 8 points on it. So, user can drag each point in order to change it's shape.

Is there any way to do this in flash?

I have some following code:

package{import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.geom.Point;

So, can anyone convert these three point curve line to 8 points circle?

ActionScript 3.0 :: Circle Circle Frame Independant Collision Reaction?

Apr 10, 2010

Trying to do circle circle collisions via math which I'm really having trouble with. One circle (player) just moves from keyboard. The ball reacts to the player. All the code shown is in my players class and I passed in a reference to the ball.

On my enterframe I have:

Code:
var xmov1 = xSpeed;
var ymov1 = ySpeed;
var xmov2 = ballRef.xSpeed;
var ymov2 = ballRef.ySpeed;

[code]....

Perhaps I'll go with a box2d equivalent instead of trying out my own physics shenanigans.

Professional :: Circle No Longer A Circle On Publish?

Feb 18, 2010

I have a simple three ring animation where the three rings fade in and out.On the stage the rings are a perfect circle, in the publish preview they look fine, but once I publish the SWF, all of the sudden the rings are not perfectly round anymore.
 
They are almost perfect but right at the top and bottom there is just a small portion which has sort of "flattened out"...

I just can't figure out how to code it so that the draggable circle can't be moved over the stationary circle.

Matrices Exist On Vertex Registers Other Than Vertex Constants In AGAL?

I've mostly seen examples where a Matrix3D object is passed as a vertex constant register in AS3 to the Context3D object. But never seen a matrix in any other types of registers (temporary or attribute).Would there be any way to copy a Matrix vertex constant to a temporary register, and then manipulate individual fields of that Matrix temporary register (ex:for the rotation), with other supplied values (vertex attributes or other constants)

ActionScript 3.0 :: Manipulating An Ext Loaded Swf?

Feb 7, 2010

So I have a simple as3 project i'm creating in FlashDevlop and I was hoping to create the layout as a simple swf thats loaded in then move the assets where they need to go. Things like roll over states would be stored on different frames to make it nice and easy for designers so they don't have to know flash. And loading it is no problem but how do you target the movie clips inside it or how do you even attach it to the root? When I say target I mean as in how would I target it to change say the height or width. I know this is broad question so even pointers to a good FAQ or example project would be helpful. I spent a little time on google but all im finding is how to load a SWF not how to deal with it afterwards.

IDE :: Faulty 3D Transformation - How To Improve

Jan 31, 2009

I'm playing around with Flash CS4 trial and tried to 'compose' a 3d Box by putting 6 MovieClips as the side elements of the box in one clip which represents the whole box. (only using the Flash Tools, no Actionscript). Within the BoxClip (after doubleclick on the BoxClip on stage), all sides look right, each side is positioned with the correct angles and coordinates. Outside the BoxClip, back on root stage, the box sides are not parallel anymore, the angles are not 90 degrees, there is no 'box' actually. So I guess, one of the problems is the 3D Center point of the objects which is absolute to one point in coordinate space. The other problem is the faulty '3D' display in Flash, that is, changing from inside to ouside a clip changes the view also. So far, the Flash GUI seems quite useless for doing some '3D'. How to improve the workflow?
