suppose i have a large, static, programmatically drawn vector graphic that extends well beyond the stage.
is it recommended to mask the graphic with the stage dimensions? does the VM still draw the portion that is not on the stage?
does masking half of a programmatically drawn graphic reduce the drawing process by half?
I have a drawn sprite- a sine wave to be exact, which is behind a layers of dynamic masks. i need to have this wave shown in different color ranges as per the amplitude.
this wave updates dynamically based on values so am trying to use something like blend mode or transparency to set the color range instead of computing it which will make it an expensive process.
how can i color different parts of the wave based on its height/amplitude range?
my current situation maybe akin to me painting myself into a corner. i have many vector shapes drawn with the Flash Professional CS5 IDE, which have been converted into sprite objects and exported to actionscript. for example, here are 3 shapes:
i want to programatically fill each shape with a bitmap from my library. i realize i can fill these shapes with library bitmaps in the IDE, but i need to scale the bitmaps at runtime as well as swap them out for others. how is it possible to programatically bitmap-fill shapes drawn within the IDE at runtime without having to also programatically redraw them?
Lets say I have a customMovieClip. I sometimes draw an ellipse with customMovieClip.graphics and sometimes a rectangle. Now I want to know what was the shape ( ellipse/rect) that was created using a particular graphics object. Doing this would enable me to pinpoint what exactly to do with that customMovieClip() instance.

I have an application that creates a chart dynamically. This chart has a lot of information plotted on it (4-6 stock trends). I want to be able to toggle some of those lines with a button. Each trend is drawn with something like this:
Code:
// establish a new Vector object for the commands parameter
var line_commands:Vector.<int> = new Vector.<int>();
line_commands.push(1,2,2,2);
// establish a new Vector object for the data parameter
var line_coord:Vector.<Number> = new Vector.<Number>();
// use the Vector array push() method to add a set of coordinate pairs
line_coord.push(0,0, 75,50, 100,0, 125,50);
graphics.drawPath(line_commands, line_coord);
How would I toggle the line I just drew? My first idea would be to put some of this code inside a function and redraw the line with the same color of the movie's background color. I don't know if this is the best option, I was wondering if I could draw this line inside a Sprite or Movie Clip and just toggle its visibility?
Is it possible to access the graphics.* - characteristics of objects that I have drawn at authoring-time at runtime? If I have drawn a single line in a movieclip I'd like to do sth like this:
[Code]...
I'm using Flash CS3 to build a simple drawing application. When the user clicks a button, they select a particular movieclip. After clicking elsewhere on the stage, the clip is instantiated and added to the stage at the position of the cursor. I've also added the option of being able to click on the added clip and drag it around on the screen. And this all works fine.
The problem is that I also want to be able to dynamically draw and add objects to the stage via the Graphics class. Whenever I add objects in this manner, their x and y coordinates are always 0,0 no matter where I place them on the stage. This makes positioning these graphics very very problematic. I created a modified positioning function specifically for these dynamically drawn graphics and while it does "work", it feels less responsive than the positioning for movieclip objects. I'm still trying to optimize this function, but it seems to me that the ideal solution is for the graphics to have non-zero coordinates when placed in the middle of the stage like movieclip objects. Is there some "workaround" to achieve this?
I am trying to draw a line from x1, y1 to x2,y2 and i want it to be a line that repeats a pattern from an image. All I can see is that you can only draw lines and change their color or thickness but I would like it to repeat an image. Is that possible or do i have to use a really long and thin rectangle with a bitmap fill?The problem is I am making a game where the user will be able to actually draw the line so i have to make it be created dynamically. The game fantastic contraption [URL] has in the game a feature where you draw lines of any length and position that are filed with a picture.
View 13 RepliesInternally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
View 4 RepliesI was wondering about MC and hey can help to lag a game out. I set up an advanced class system so i don't have to use MC to simulate walls, all i use isthe x,y,width and height. Well anyway since i don't need MC anymore I was wondering if there is a way to attach Graphics instead of MC cause a Graphics file size is relatively small than that of a graphic, I think. If anyone could tell me thats true and show me a way to attach graphics that would be nice. I haven't tried it yet but maybe if I exported the graphic from the library imihgt be able to call its name, but it doesn't have an instance name so im stuck.

I have a large vector drawing (imagine 5000x5000) that i want to break up into separate pieces. I know that I can convert this vector drawing into a bitmap and then use the copyPixels method to create many separate bitmaps of the different regions of the original vector drawing, but is there any way to subdivide it into movieclips that just contain vector graphics instead of a bitmap?The reason im dividing a big chunk of vector graphics into smaller pieces is for performance reasons, so flash would only render a small part of this big chunk at a time (only certain regions/voxels/subdivisions are rendered at a time). But bitmaps apparently take up a lot of memory and the system im using would take much less memory if these subdivisions could be preserved in their original vector graphics form.
I imagine I could use masks somehow to achieve this effect (for each subdivision, duplicate the huge image and mask only the region that the subdivision represents), but I dont know the performance costs of masking or if this will create other problems.So is there anyway to split up a movieclip of vector graphics into smaller movieclips of vector graphics the same way copyPixels can with bitmaps?
i've attached my flash file. I don't get why the path is not drawn if the movieclip is set ask mask. I would like to slowly reveal the text.

I have been looking for a preloader such as the one at [URL]. The preloader there is just the effect I've been looking for for a long time. I know it's done with scripting, but I could never make it quite right. I even posted here a few times, and found a tutorial, but it used a drag bar to control it, not bytesLoaded. Any tutorials that you could lead me to that focus on making it a preloader

View 1 RepliesI'm trying to make a program that's meant for graphics tablets in AS3. So far I can allow the user to draw a line across the stage so that they know where their moving their pen around. However I want this line to only be temporary, and so the graphics.Clear() method is called to remove it.
I'd like this to look a lot better however, as the line just instantly disappears. Does anyone know how I could add code that makes the line fade out to 0 alpha first before I call the clear command?

Where template is a canvas. Its rotate nicely but the problem is the position is not in right place. i.e. it is not in (50,50) after rotate.
I want to use numbers I've drawn myself to represent a number, but don't know how to implement this. How would I display the equivalent of an integer with these numbers? If it's necessary to have them in a tile pattern, which makes sense to me considering how older games worked, then what code would I use to switch between each? Or is there another, better way? Also, I need the number to be able to adjust to the number of digits in the number and read from left to right (so the 1 in 10 would be in the same place as the 1 in 1).

If i draw a movieclip on a frame (root) as such:[code]This will draw a simple square from position 20,20 on root. Now if i trace penName_mc._x i would expect it to give me the distance from the root origin i.e. 20 however it always produces 0. My questions are:
1- Why doesnt it consider x as 20?
2- Is there no way to determine the x of this newly created movieclip from the origin? (besides drawing from 0,0)

On mouse move i have a line drawn using lineTo method. This works like in Paint or most drawing programs: the mouse drawing like a pencil. What i need now, and dont know how to accomplish, is to add a number of mclips over that line. And this mclips should be over the line but separated to each other (different x and y of the drawn line). So in the end when moving the mouse the user should get a line and, every certain distance, a number of mclips over it.
