Where do I can find an example or a tutorial of a realistic simulation of a rope tied between two points? I need to make something similar to the interface of Reason, the music app.
View 6 RepliesI have an Actionscript class we'll call Person to make the example easy. I want to have a DataGrid populated with Person objects that has columns displaying things like Name, Birthday, etc. All that is nice and simple, but I would also like to add a checkbox column to select certain people in the DataGrid. An example use case would be as follows:
Display all people. User checks a box next to each person indicating they want some action taken on those selections. Some action is taken on the user selections when the user clicks a button.
It seems like the common solution to this is to make a Selected property on each Person object, but that isn't really a good option for me. The Person object is used throughout the application, and it seems very unclean to have a Selected property which really isn't a concern of the Person class.
I like the type safety of having hard classes like Person, but I don't know how to solve this seemingly simple problem so I can loop through the objects and determine if the person is selected or not.
i am searching for a rope that has something attached at the bottom and i can swing it around by dragging the rope from the top(not from the object attached). it might be a rope(more flexible) or just a rigid line, like a draggable from top pendulum.
i came across the box2d physics engines and erik hagreis' site made with menus that are suspended with ropes. but im still stuck, i dont know how to make the ropes draggable from the top(instead of from the bottom, as in erik's site). if anyone has a hint or an alternative solution to using physics engines, let me know. im out of searches, i searched the whole net...

View 1 RepliesIf I have a component that has some states defined, is there a way to make changes in design mode but not have it tied to a particular state? For example, if I have state1 and state2, any changes in design mode will be based on state1 or state2 (i.e. width.state1). I understand this is the direction Flex is going in but I'm transitioning from a Flex 3 app and right now I just want to make the change to width and not width.state1.
View 3 RepliesI'm developping a gameplay concept using AS3 Fisix engine in which I need for a pendulum to be frictionless. The idea is to define the head and tail positions (using the Fisix's Rope resource) by mouse clicking and dragging in the screen and let the pendulum swing so that it goes forth and gets back to its starting position without losing momentum, and keep doing this repeatedly.
So far, I managed to make the pendulum swing normally but still being affected by friction and gravity (it keeps moving until got totally still, like a real-life pendulum would do). After many trial-and-error experimentations, I realized that I couldn't find any obvious parameter to work with, either in FisixEngine instance or in the Rope object itself, which allows me to remove or disable the friction from the simulation so that the frictionless behavior could be achieved.
I'm having a heck of a problem with the startDrag function in Flash right now. I'm trying to make a draggable and/or clickable curtain rope, which works now to a certain extent. When the user single clicks on the rope, it opens/closes itself. When a user clicks and drags the rope part of the way, it opens/closes itself the rest of the distance. A user can also click and drag the rope the whole way if they like. Everything does what it is supposed to when a user single clicks. If a user double clicks, the curtain is permanently draggable, which is obviously not what I'm going for.Variable used to determine whether the curtain goes up or down
drag = 1
// Starts the dragging[code].....
I have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
I'm trying to make a car simulation. I've a car that moves with keys W,A,S,D and i've a map with size 1200x1400 and screen size 600x700.What i'm trying to do is when car moves any place on the map , screen shall show that area of the map. The area that car located on.

I was wondering if anyone would be able to help me with a problem I am having. I am trying to develop a simulation of a browser in Flash, and need to have a button which allows users to be able to go back to a previous screen (e.g. another .swf file) which means I need the window to be to move between .swf files.
I have tried various methods I have found online, but none seem to be working.
i am currently making a flash "pond" with fishes in it, and i have the ability to add food pellets onto the pond, how should i make the movement of my fishes to the food x,y location ? so it will be smooth , rather than setting the x,y location of my fishes to the x,y location of the food pellets.Also is there a good place to learn how to make my fishes move by its own?Fish class

I'm trying to preload external swf files as needed and show the progress each time a file is being preloaded. It works exactly as intended when I simulate it on my desktop but not at all when uploaded on the web: first of all nothing happens up until 50% of the main movie is already loaded and then when the the attempt is being made to load additional content, some weird number displays (-214...%) instead of the percentage.

I painted my stage black and when I simply run my flash file it traced "loaded" so everything is loaded well and it builds the UI. But when I simulate by pressing ctrl+ enter twice I get a white screen and after about 10 sec. (my swf is 1mb and it simulates at 100kbs) it displays the preloader instantly at 100% and loads my UI. So my text doesn't change from 0% -> 100% but I just get 100% when everything is loaded.
I'm trying to make a realistic scrolling terrain for a game I'm making. all of the movement and collision detection is 2d, but I need to make the terrain look more real.
does anyone have an algorithm for simulating a 3d terrain in 2d with the geom.Matrix class?
I know how to implement one, but I'm not sure about the logic for a transformation like this
Try to simulate the OnPress/OnRelease aspect of earlier versions. It is working so far, but when I press the space bar, it goes around once, then stops. If you check the output, it is looping back to the enter aspect, so it looks like it is not working, but it just keeps restarting. I need to make the enter frame event not work since the keypress is already down, and only work on the first time I press it.
var spacebarKeyDown:Boolean = false;
stage.addEventListener(Event.ENTER_FRAME, moveChar);
function moveChar(event:Event):void{

I am looking to make a 100% deterministic Flash simulation (for multiplayer RTS game). So far areas that require special attention identified:
ActionScript Code:
Math.random() // obviously, have to use Seeded random
Number // floats are volatile, but that can be overcome by truncating precision
For.. in and For Each loops: // the order of looping through properties on an Object is different every time
So im trying to create a simulation Earths orbit around the Sun. Before i begin coding i need to know earths real orbit lengths.Does anyone know the values of (A,B,X,Y) variables?And once i do get the values, what is the code for moving an object in an ellipse? I know i need to use cos and sin but i dont know the actual formula.
Edit: I found out that [A] is 152,098,232 km and its [B] is 147,098,290 km. I'll scale these down once i find out the [X] and [Y].

View 3 RepliesI'm creating a simulation in which a large number of objects are added to vectors and then taken away in random order (as more are being added). To remove the objects, I splice the object from the vector it's in, and notify all the other objects that an object ahead of them was removed so they can change their indices accordingly. As far as I know, the objects have no other references (I think), and within the object, I set everything to null. I read somewhere that you can't put "delete this" in the class, so I didn't bother with that. Will this be sufficient to get the object garbage collected, or should I do something else? What are the best ways to get something like this garbage collected?
