View 9 RepliesI am trying to make an animation where there are several locations(say A,B,C,D,......) made on a map. If a person clicks on one location A and then another location B, I wanted to draw a dotted line from point A (from destination of the plane) to point B (to destination of the plane) using AS3.
View 15 RepliesI have a motion tween right now with a moving point that is following a copied and pasted motion path. Is there a quick way to have the point draw a line behind it as it moves along the motion path??? I can't seem to find a good way to do it in AS3.
View 1 RepliesI 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.
I am very new to actionscript 3.0 & currently i have a project to do that required actionscript.
ActionScript Code:
package{ //package
import flash.display.Sprite;// for sprite, to prevent 1046 error code
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.
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.

View 1 RepliesThis should be a bit of simple geometry: How do I calculate the points to draw the lines in the code below so that it makes a 2D cone or wedge shape?
import flash.geom.Point;

UPDATE:I should have mentioned my aim is not to draw a wedge shape, but to draw a line from a random point to the edge of an existing circle.If you're more comfortable with algebra than actionscript,
I am developing a white board application which allows the user to draw line with arrow head (some like Microsoft Word line with arrow feature). I am using graphics property along with lineTo() method to draw a line. Now i have to draw a angular arrow on the last point of line. I am drawing the arrow by connecting the points around last points. As 360 line can pass through this point and each line can have a different angle of arrow.

It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
we have values generator that outputs someting like FF00FF5F. We have some coordinates like 50, 300, 10. We want to draw a point in 3d on stage. Not using PV3d or anething like that. thay say there is going to be no default z sorting but I can live with that...
View 1 RepliesI have a movieclip on stage that I draw into a bitmap, how do I change the registration point, the code below produces bitmap with half chopped off:
var bitmapData:BitmapData = new BitmapData(mc.width, mc.height, true, 0x00FFFFFF);
var matrix:Matrix = new Matrix();
matrix.translate(0, -mc.height/2);
[Code].....
I didn't know where this should go; I thought this was the best place. In Actionscript 2.0 I'm trying to draw the shelf of a closet (wall-to-wall) but I don't know how to.
View 1 RepliesI'm attempting to make a curve drawing tool a bit easier to use.Rather than drawing a basic curve and then clicking on the control point to change it, I would like the user to be able to click on the curve itself to change it, much as you do in the FlashIDE.So, given start and end points, and a point on the curve, how do you determine the control point for use with the MX API?(I googled this, but found mostly info on cubic rather than quadratic curves)

I'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.
How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)
[Code]....
But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
i have the follow issue :
I have a point which is setted at the border on a component, with changed transform point to the center of a component in order to match the component rotation.
the important part is when i try to get the point XY after rotation - they remains the same as before rotation.
how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
if i have a movieclip or a sprite could i find (via code) where is its registration point compared to its top left point (no rotation included) ?

Hi I am trying to create an image scroller that just scrolls images from point a to point b on load horizontally in an infinite loop. I just used a code snippet to move it horizontally but don't how to get it to stop and at point b and loop again from a.

I am trying to develop a Quadratic Bezier Curve using the graphics.curveTo() method. Initially when i drag mouse to draw the shape, i use start point and end point of mouse to draw the curve line. I assume control point at any position below or up to the line. An draw the curve using this control point. some what like:-
[Code]...
Now i add a tip on this curve segment. I have x and y position of tip. I want to change the curve segment by dragging tip. but now i don't have the exact control point according to tip position. If i use tip coordinate as control point it reduce the height of curve and now tip does not lie on the curve segment. What i have to do is calculate the exact control point on the basis of tip coordinate. But i failed to get this point.
how to use these in order to make an object move from point A to point B in an arc.Think of that classic game where you have to input the angle and power and try to hit your opponent.
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.
http:[url]....
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.
From the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?
