[Beta] A* FlashString

Oh, fantastic, very cool. Nice work on yet another useful extension Pharanygitis, and thank you.

Thank you for this, great work!

Interesting extension, thanks

Could you explain the string format a bit more if possible. Would i be right in guessing it is tile based so 1-1#1-2#1-3#1-4 means they are all the first tile on X and then going down a tile each on Y?

Awesome. I've been waiting for flash pathfinding.

Atom: Yes it is a tile format. Your guess is correct.

X-Y# is the x/y coordinates of the node along the shortest path. If you watch the example, the ball moves along the string coordinates in reverse order (the destination is the first coordinate in the string).

X - X Coordinate
X - Y Coordinate
# - array delimiter

Just started playing with the extension and I think I've found a bug.

If I path once, that's just fine. But when I path again, the path is appended to the end of the last path, so the string returned is the old path + new path. Path again, and I get the two previous paths + new path, etcetera.

Please login to see this link., and Please login to see this link. that shows the problem. Click on a tile, it finds the path from 0,0 to the tile you clicked on.

Would love to get a fix for this!

If anyone wants a hack-fix whilst Pharanygitis fixes this, use two Strings, a FullPath and a RealPath, and a counter/global value to keep track of where the real path should start in the fullpath. Then:

I'm sure a real fix will come soon, it's just clearing the String every time the AStar function is called, right?

Fantastic. Works perfectly. Thank you!

I have a problem that didn't happen last time I used this extension (recently formatted my hard-drive).

Now it seems MMF2 can't find the extension.. any ideas?

Thanks, but doesn't work. I downloaded some more of your extensions and none of them work. Do I need some external file or something?

It just says "Cannot load extension"

Edit: D'oh! Might be a good idea to install flash player first... Works perfectly now :blush:

In the example, why do you use two string tokenizers instead of one 2D string tokenizer?

Hey,

It seems the download link is broken, and the extension list on your site gives me the bug DizzyDoo described.

Great extension, by the way! Saves me a lot of time

Edit: Ah, it seems it is fixed after all, I'm doing something else wrong. I'll figure it out. Sorry for the trouble!
