Is there a way to use the scaleX and scaleY property in conjunction with the Tween class to scale from the center?ActionScript Code:[code]above unfortunately only scales from top left. This is not a class I can go in and move all the content by hand (so that the registration point is in middle) as it's all dynamic. I've looked al over but none seem to make use of the Tween class.

Now I am using the Tween Class to move some boxes in my movie, now I can move the first mc and then another mc after the first tween has finished with onMotionFinished but I was hoping someone could help with how do I start the second tween when the first mc has passed a certain _x coordinate. ie starting the second mc moving while the first tween is still moving.
View 1 Repliesthis might be an easy question but i have not found the answer. i want a MC to move vertically upwards and then stop. i have the code below but this tweens downwards. i tried changing the -30 value but it doesn't seem to change the starting point. import mx.transitions.Tween; import mx.transitions.easing.*; var xPosT:Tween = new Tween(kText,"_y", Bounce.easeOut, -30, 56, 3, true);}; xPosT.onMotionFinished = function() {};
View 3 RepliesI have a column of objects down the center of the stage and I need them to randomly point either to the left or the right. They have been placed using a for loop so I can't point each one individually. I was told I could use Math.random to flip their scaleX position but I can't get it to work.
View 4 RepliesI am trying to scaleX and scaleY tween a movieclip. the problem im having is instead of growing frrom the centre of my movieclip, it seems to be scaling from the top left hand corner.

i have a tween that moves a progress bar along the x using scaleX but when the user presses a button i want the progress bar to scaleX -= 0.2 but when i do this it scales to taht size but immediatly jumps back to where it was in the tweener tween.
View 1 RepliesI'm trying to figure out how to find a point relative to the center of an object, modified by its rotation. For example, in the attached swf, I've been messing around trying to draw trails to a bitmap, coming out of the thrusters. I didn't have a problem at first, but as the ship rotated, the lines that were being drawn wouldn't remain relative.

I'm sure this is because I have no idea what I'm doing, and I've just been sort of idioting my way through it. That aside, is there an easy way to find the point I'm looking for? For instance, say I want a point at Y -14 of my ship, but I want that to remain relative to the ship as it rotates.
I'm using a tween on an imported file on MOUSE_OVER and MOUSE_OUT that will scale it X/Y up by 1.2. The problem is that the scaling starts in the upper left hand corner and moves out from that point. I want the scaling to start from the center.
Code:
new Tween(clipT,"scaleX",Elastic.easeIn,this.scaleX,1.2,.5,true);
new Tween(clipT,"scaleY",Elastic.easeIn,this.scaleY,1.2,.5,true);
I have a dynamic image loading into a movie clip and i dynamically created a transform box around it. However the anchor point of that transform box is coming on the left top instead of in the center, which is not letting the image transform properly. how to dynamically put the anchor point to center through AS2?

View 1 RepliesI'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.

View 5 Repliesbasically just wondering if its possible to scale an MC about the center of the stage as opposed to the top left of the MC? I thought about setting the X & Y as stage width / 2 + MC width / 2 but cant as the user needs to be able to move the MC which is much bigger than the stage and zoom in on a point in the center rather than just the center of the MC.

I'm making a 3D room builder. The user places Sprites around the 2D stage and my script converts those Sprites to Papervision3D DisplayObject3D objects. I'm having problems with the 3D object positioning because Sprites have registration points at their top-left corner and 3D objects have registration points at their center. How can I make that conversion?ere's a scheme of how the 2 different coordinate systems work:

View 1 RepliesI've created an mc which functions as my map and controls to go with that which allow the map to be moved around and key points navigated to and zoomed in on at varying zoom levels.I'm using scaleX and scaleY to scale the map mc and a list of x and y positions to correctly position the map for each key point.When I want to go to a certain area I perform this calculation (offsetX and offsetY are the center of the screen):
newX = posX * scale + offsetX;
newY = posY * scale + offsetY;
Then I tween the position and scale of the map to smoothly scale and move the map to the correct position:
var tween = new TweenLite(_background, EASING_SPEED, {x:newX, y:newY,scaleX:scale.getScale(),scaleY:scale,ease:EASING_TYPE,onComplete:moveToComplete,onCompleteParams:[room]});
I now need to implement a zoom in / out function and this is what I'm struggling with. The zoom should use the center of the screen as the reg point for the scale, so I've been trying something along the lines of the following to get the correct positioning:
var newX = offsetX - (offsetX - _background.x) * scale;
var newY = offsetY - (offsetY - _background.y) * scale;
So in my mind this gets the distance from the current position of the map relative to the center point of the screen (offsetX, offsetY) then scales that distance by the new scale. However, this is clearly wrong because it's not working and the positioning of the map is wrong.I've also tried using a transform matrix to get the correct values but I know even less about them and not got the right results.
function scale(target:MovieClip, center:Point, scale:Number):Point {
var m:Matrix = new Matrix();
m.translate(-center.x, -center.y);//move the center into (0,0)

How to find out different circle's center point of a bitmap?
just like photo above, how can i locate the 2 center points of circles?
i only know using .getColorBoundsRect to get a point, but this only apply to one circle, in fact i wanna get different points according to the bitmap.
I'm trying to add some zooming functionality. The problem is that when you zoom in and out, it scales the MC up and down from where the registration point is. This means That when I'm far from the position of the registration point instead of zooming the in straight it also makes it appear as if you are travelling towards the registration point.
To offset this effect I want to calculate the amount of pixels I need to offset the Map by so that it appears as if you are zooming in directly.
So just as a test I've put a little ball inside the map(called "center") which I'm trying to keep in the center of the map.[code]...
I draw a shape,like follows:

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 start with a question: how could I change the registration point of a movie clip created or loaded at runtime? I want to move the registration point from top/left to center.
