[Flashcoders] netStream.close()
does anyone know how to close down an open netstream and stop it from downloading data? so after I call a netStream.play(flv) if I call netStream.close() it doesnt seem to stop it from dlownloading data. or even do what the livedocs say it should for that matter. kinda sketchy.. what if I called netStream.play(flv) just with a non existant flv?? would that stop it? smith ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
RE: [Flashcoders] HashMap?
Well, yes. Now that I think about it my test didn't make much sense, since there would be no way of determining how keys are generated by insertions alone...I was assuming a uniform distribution, and it can't be done without knowing more. But I believe that the Flash uses a tree to implement its map, for some of the same reasons you mentioned. It's just a way more efficient structure to use if your data is unknown, grows well, and stays balanced.

Wouldn't it be true to say that hash maps will get slower as the probability of collisions increase? As the primary area fills up, there will be more occasions when the new key to be added, hashes to a storage location already occupied and a link structure will be needed to store the key(s) in the overflow. Similarly, lookups will start to hit links rather than data which will require that the links into the overflow area be followed. This is where tuning comes in. The fact that there are no tuning options makes it unlikely that hashing is used. Defaults would be hard to set without wasting space or turning the whole thing into a small set of linked lists which work be long to search. It would not be seem to be a very good choice for a default implementation of Arrays. Ron Scott Hyndman wrote: You could figure out how it's implemented by doing some experiments. Dynamic hash maps have constant insertion (amortized) and lookup time. If the map is implemented using a B-Tree, then you'll see O(log(n)) times (so just see if the more properties you add increase the amount of time it takes to add them).

I would hope that it is efficient but hashing adds a lot of overhead and wasted space for small arrays and really needs to be tuned to get the desired results for larger arrays. If the arrays are stored in sorted order, then the normal key lookup can be done as a binary lookup which will be a lot quicker than an exhaustive search. The price is paid when a new associative entry is added. Nothing is free. None of my work has required has involved large associative arrays where hashing would add a significant improvement in speed but it would be nice to have such a class available for those who need it.

There does not seem to be any way to control the hash parameters and every array would have a lot of wasted space for nothing and without any way to control the hash size and the percent utilization, you would not get a lot of advantage for the big arrays. The Java HashMap defaults are pretty modest and would yield less than optimal performance with a big array. You can set the parameters if you have a big array and know a bit about the randomness of your keys to get fast lookups with a reasonable trade-off in wasted space Perhaps someone who knows the Flash Player internals could tell for sure.

I'm really hoping someone can help... I need to plot points at an equal distance along the circumfrence of an Ellipse. As it turns out, I'm pretty bad at geometry, which doesn't help. I can plot the ellipse, but because I'm using sine/cos and incrementing with theta the points are crunched towards the outside of the major radius. I've tried a bunch of different approaches- recording lots (5000) of points, then stepping through each to compare actual distance but I'm not getting nearly accurate results this way. I've looked at drawing dotted/dashed curves from drawing api/ custom classes but no luck. If I could affect theta at the same rate the ellipse is plotted I think I'd be ok, but I can't quite grasp it. I've read all sorts of impossiblilites about this,and a lot of people having miserable experience with this sort of thing (one guy spent 8 years trying to fit an equal-sided polygon in to an ellipse). But- at the end of the day I can go to the Flash IDE and draw an ellipse and stroke it with an equally spaced dotted line! I just need to do this dynamically and record the points... Any thoughts?

Re: [Flashcoders] Assetpropflags back to default
There is no default. If you need to restore the state, then you have to first find out what that state is. There are some methods on that page, which describe how to do that (though it's fairly clumsy). For example, if you need to find out the dontEnum value, then you do a for..in loop and see what turns up. Then, once you have changed the value, do another for..in, then figure out the difference. readOnly and dontDelete are harder, since you actually have to change the data. To un-set a flag, use 0, then pass the bitwise flags as the 4th argument.

Re: [Flashcoders] Proxy for Express Install
i think setting up your own proxy for express install would be way more trouble than it's worth... you'd have to have every plugin version and do platform sniffing and return the correct plugin for each platform.. then when adobe updates the Flash player, you'll have to update all your stuff... it wouldn't be very much fun. it sounds to me like the DNS hasn't propagated across to some of your DNS servers yet. so as a temporary fix, you could try replacing the fpdownload.macromedia.com in the express install code with the ip address of the server (make sure you get the ip address from a computer that the install works on) i don't recommend this as a permanent fix, but it might work until adobe takes care of their DNS issues. you should also try e-mailing someone over there - the flash developer relations person (i'm not sure who that is anymore) and see if they have any insight into the problem.

[Flashcoders] BUG: setMask calls onLoadInit (or setting a mask?)
Ok, I've discovered the problem I was having previously -- to sum up, I have a .swf movie that plays beautifully on its own. I then started coding a shell to, on different durations (setInterval) load in this and other .swf into a movieclip. I've been VERY careful about scope issues, not doing anything in _root, but each 'sub' flash has it's own named movieclip to load all it's do-dads. The SHELL movie uses a MovieClipLoader to load in each of the subclips, and it's main object, gPlay (a global) has a gPlay.onLoadInit(ev) as it's listener. When the SUBCLIP does a SETMASK on some movies, they trigger the gPlay.onLoadInit !!! Now, here's the interesting tracing: SETIMAGE MASK SETMASK_level0.mc_1048578.imageL X: true IN TF SETIMAGE MASK SETMASK_level0.mc_1048577.imageL X: true IN TF SETIMAGE MASK SETMASK_level0.mc_1048576.imageL X: true 7459 dispItem _level0.mainWindow.mc_1 7459 EV _level0.mc_1048578 mc_1048578 7459 7459 dispItem _level0.mainWindow.mc_1 7459 EV _level0.mc_1048577 mc_1048577 7459 7459 dispItem _level0.mainWindow.mc_1 7459 EV _level0.mc_1048576 mc_1048576 7459 startItem So it seems that the mc_1048576 is a new movie that is created based on the setMask and then triggers any 'onLoadInit' --- ??? WAIT: In the subclip I've set 'this._lockroot = true' as a test. I've changed any 'setMask' to manually masking in the timeline. I'm still getting something weird: EV _level0.mainWindow.mc_1 mc_1 7347 7527 dispItem _level0.mainWindow.mc_1 7527 EV _level0.mc_1048578 mc_1048578 7527 7527 dispItem _level0.mainWindow.mc_1 7527 EV _level0.mc_1048577 mc_1048577 7527 7527 dispItem _level0.mainWindow.mc_1 7527 EV _level0.mc_1048576 mc_1048576 7527 startItem POS: 0 SUBIMAGE _level0.mainWindow.mc_2 14402 dispItem _level0.mainWindow.mc_2 14402 EV _level0.mainWindow.mc_2 mc_2 14402 startItem POS: 1 SUBIMAGE _level0.mainWindow. ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
