Apr 19, 2011i want to find third Point of Triangle i Have two point p1,p2 with respect to it i want to find third point of triangle
Note one thing triangle is 45 - 90 - 45 degree so the point i want to find is at 90 degree,
so as per my requirment p1 = 45 degree p2 = -45 degree and p3 = 90 degree so i want to find p3
ActionScript 3.0 :: Find The Normal(x,y,z) For A 3d Triangle?
May 11, 2011In my quest to build a terrain with proper collision detection, I've reached another stalemate. What I need is to be able to find the normal(x,y,z) for a 3d Triangle. before I start to build everything from scratch, cross products and all that jazz. I want to check if someone's done this before or can give me their 2 cents of how to do this the best way.Given 3 verticles with (x,y,z): v1, v2, v3 How do I find the Normal(x,y,z)I'm using away broomstick, and as far as i can tell there's no support for normal calculation. You would think that .subGeometry.vertexNormalData returns the proper normal, but it doesn't.

Nov 18, 2011I am currently looking at a way of visualising data and a part of the algorithm needs something 99% the same as A* Path Finding but I cannot wrap my head round it fully. I know it will be a fairly simple modification. (specific cost instead of least cost)
Basically I need to plot a path (2D Grid, no Diagonals) from point A to point B in X number of steps.
E.g. If the start and end points were right next to each other and I needed the path to be 3 steps it would have a tiny loop. (moves: up, right, down). Is there a known name for this algorithm or is the use of this so rare it's uncommon? I am currently looking at this AS3 Librbay for modification as it is apparently very fast and seems clean and simple to me:[URL]..
ActionScript 3.0 :: Find Most Left And Top Right Point In A Sprite?
Aug 8, 2009I once needed to pan a sprite full of movieClips (picture 1) which were draggable with no bounds so you could drag them up and left (higher than sprites registration point).
You could also drag them down and right and expand a sprite that way (as well) but that didnt matter.What did matter was how much is 'up' and 'left' from the sprite registration point so i can include that in my formula for panning.
This was easy to find, i just sorted my array of movieClips, sorted on x and sorted on y after each drag, and thats how i got my up and left points.
Now I am trying to do that same thing, exept my movieclips inside a sprite have a custom rotation (picture 2), so i also have an up and left point, except this time up and left are caused by rotations of movieClips inside a sprite... (and these are dragable as well with no bounds)
ActionScript 3.0 :: Find X Position Of A Point On A Line?
Aug 22, 2009To make this easy, lets say I have a movie clip with a diagonal line in it (top left to bottom right).
I want to start my y position at 0, and place it in a loop and increase y by 5 every time. So we start at the top left of the clip, and move to the bottom of the clip.
Now since we have our y value (0, 5, 10, etc.) would you get the x position of the line? such as (x, y):
5, 10
or
42, 15

ActionScript 3.0 :: Find Highest Point Of A Group Of Boxes?
Mar 31, 2009I have a number of boxes on screen - each box is a rectangular movieclip, and they fall to the bottom of the screen where they pile up to make a stack of boxes. I'm using box2d for the physics. Oh, and each box may be rotated. I need to find the highest point - ie the smallest y value, of the stack of boxes.
Obviously I can find the position of the highest box's registration point easily (which is the centre of each box) - but that may not be the highest point of the pile of boxes. The highest point may not even be the highest box - it could be a lower box that is rotated on end, for example.
Flash :: Find Number Of Touches At A Point In Time?
Dec 7, 2010I want to find out if the user is currently using more than one finger to draw on the screen.currently, the TouchEvent object doesn't have any property like touchCounts, which tells the number of touches on the screen. it just has a touchPointID, which helps to identify a particular touch.
do i need to handle this on my own ? for eg: in the TOUCH_BEGIN event handler i could see how many different unique touchPointID i have received and update the count myself.

ActionScript 3.0 :: Four Circles - Find Intersect Point Between Lines

I've uploaded the SWF here: [URL].

ActionScript 3.0 :: Find Center Point Of Mc With Dynamic Scale?
Dec 1, 2010I'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]...

Oct 30, 2009So I have a ground that's supposed to be, for the most part, curved. How can I find the utmost y point of the ground at a given x? The ground looks like so: The function I have right now sort-of works, but seems very inefficient. You input an x parameter, and the function loops using hitTestPoint with a constant x and a y that increases until it hits the ground. Then it returns that y value. Is there a better way to do this? This method seems like it would get slow.
