ActionScript 3.0 :: Reassign A Point In 1 Line?

Dec 11, 2010

is there a short hand way to reassign a point in 1 line?

something like:

Code:
var p:Point= new Point(0,4);
p= [5, 10]; // doesn't work
i know you can just say
p.x=10;p.y=40;

but when auto formatting it will drop it down to 2 lines

ActionScript 2.0 :: A Line From One Point Past Another Point And Whether It Hits An Object?

Aug 19, 2009

I am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.

Flash :: Reflection Of A Point Over A Line?

Aug 4, 2011

I have been looking at how to reflect a point in a line, and found this question which seems to do the trick, giving this formula to calculate the reflected point:

Given (x,y) and a line y = ax + c we want the point (x', y') reflected on the line.

Set d:= (x + (y - c)*a)/(1 + a^2)
Then x' = 2*d - x
and y' = 2*d*a - y + 2c

However there are two problems with this implementation for my needs:

My line is not described in the form y = ax + c (so I'd have to translate it, which is easy to do, but it means the process is slower). What if a is infinity ie. a vertical line?

Is there a simple way to calculate (x', y'), the reflection of point (x, y) in a line, where the line is described by the two points (x1, y1) and (x2, y2)?

Edit:

I've found a formula which does this, but it seems as though it does not work with lines that look like they have equation y = x.

Here it is in actionscript:

public static function reflect(p:Point, l:Line):Point
{
// (l.sx, l.sy) = start of line

ActionScript 2.0 :: Reassign Actions To Several Buttons

Jun 5, 2008

I have rollOver, rollOut, and Release actions on several buttons. I want to be able to keep the same buttons but attach different actions depending on what section of the site the user is in. I have something like:

Code:
myClip.onRollOver = function():Void {
this.swapDepths(5000);
Tweener.addTween(this, {_xscale:110, _yscale:110,
_x:xArray[substring(this,12)] - 10,
_y:yArray[substring(this,12)] - 9,
[Code] .....

I tried just reassigning it and also tried
_root['box'+i].onRollOver = function():Void {null}
before reassigning it. neither worked.

ActionScript 3.0 :: Find X Position Of A Point On A Line?

Aug 22, 2009

To 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

ActionScript 2.0 :: Draw A Pixelprecise Line From One Point To Another

Feb 15, 2010

I wish to draw a (hair-)line, from one point to another. The drawing-api at [URL] gives a nice explanation, but flash is slightly off. The lineTo statement draws a line towards the specified point, not to. It's probably a matter of opinion, but I'm fairly confident that we all agree that drawing a line from (1,1) to (5,1) should result in a line 5 pixel long. That's how we've all learned it when we were young, that how other programming languages do it, etc. (One could state that 'going to school' doesn't mean you actually enter the building , but that's just avoiding the issue) But not Flash. Drawing this line results in a line of only 4 pixels long, the line stops at coordinates (4,1). I can see the benefits in this when drawing (transparent) connected lines and closed shapes, but it has it's drawback when creating single lines.

I'm probably not the first one to run into this problem. Maybe it's just a setting somewhere? How do I get flash to draw a line to the exact point I specify? Preferably without having to analyze the direction of the line and moving the destination coordinates one pixel further.

Flex :: Adding One Point To Line Series Without Everything Getting Redrawn

Apr 19, 2011

I have an air app that collects live data from a user's action and graphs it.It records data every second and charts it on three different line series from the same array collection.This works out great at first, but it gets worse and worse as time goes by. When it gets close to an hour it's almost unusable.I'd like to be able to add a point to the graph and have flex JUST draw the new point and not invalidate the whole series and redraw it. Is this possible? I'm willing to override something to make this work.My last ditch effort is to take the average of 5 or 10 points and only adding those. This will still work poorly when the user is going for 3 hours or so, but I can't think of a better way.

ActionScript 3.0 :: Draw Straight Line And Snap To That Point

Nov 19, 2009

I am very new to actionscript 3.0 & currently i have a project to do that required actionscript.
ActionScript Code:
package{ //package

import flash.events.MouseEvent; //for mouseEvent, to prevent 1046 error code
import flash.display.Shape; //for shape, to prevent 1046 error code
public class gridDrawLineTesting extends Sprite //for mouseX mouseY
[Code] .....

This is the code that I have found from various web and paste it into one. I want to draw straight line & snap to that point at the same time. My problem is when I click at 2nd point, there is a 'extra' line at (0,0) joining towards my 2nd corrdinate point. I want to get rid of that 'extra' line.

ActionScript 3.0 :: User Drawing A Line By Dragging A Point

Aug 19, 2010

I've been unable to find info on this because it's tricky to find the correct keywords. I want to allow the user to draw a line so that the application can measure the distance between two points chosen by the user. I could let the user click on one point and then the other but it would be much better if, after clicking the first point, a line would follow the mouse cursor like in most graphic applications. How would you do that? Is there a convenient method for that? Maybe use the MOUSE_MOVE event after the MOUSE_CLICK and continuously draw a line?

Actionscript 3 :: Get Ending Point Of A Line Drawn With LineTo In Flash?

May 10, 2011

I have drawn a series of lines using flash's graphics.lineTo command, and placed them in an array to be referenced later. Based on certain user interactions, the clips that hold these lines can be shifted to the right, causing the lines to move with them, no longer connecting to the point they originally connected to. So I need to extend the lines by the amount their parent clip was shifted (I've called this incVal). So what I need to do is find the point at which each of these lines ended at, and draw from that point to the left by incVal. How do I get that ending point of the line?

This is my code:

To draw line and add it both to the clip and to an array for future reference:

line.graphics.lineTo(localPoint.x,localPoint.y-10);
membersRef.addChild(line);
parallelArr.push(line);
