Description
Instructions...Click to double grid, space to reset. If flash brings up a slow script warning, click no to keep on going or click yes to keep what you've done
This is land generation using the fractal method. I learnt the method from ChevyRay's blog post

Now in case you are confused ill explain what it does. First it creates an 8x8 grid and fills it randomly with blue/green tiles. Now when you click it's going to double the grid (16x16) and double what was already there (GBBG becomes GGBBBBGG). Now for each tile it checks the nine tiles around it. Now depending on what's around it it has different chances of being G/B. Then you keep on clicking until you get to 512x512
I originally did this in AS2 but it was very slow (Flash would bring a slow script message on 206x206). Because of this a decided to read up on AS3 and convert it. this took 6 frustrating hours! Tell me when on your computer it brings the first slow script message (15 second time-out I recall).
Okay well I'm going to update this more with some funky features later!

Yeah I've been meaning to do that for quite some time now but i've just never gotten round to it

This looks pretty nice, it's useful for making maps for RPGs.

Yeah, I was going to make a game using it but i've got too many things to do at the moment

at first sight, it reminded me of Golden Sun.

How did you calculate the probability for the change of a square?
👍: 0 ⏩: 1
Each square looks at the squares around it. If 3 squares are green, it has 3 in 9 chance of being green. At the very start they are purely just random

Ok, so I did basically the same thing as you ([link] ).

Remember that's double the size of the box.

Wow, this is really cool. Actionscript really is quite beyond me, especially AS3, that's an ENTIRELY new level, there.

Hey AS3 isn't that different two AS2, it just takes some time to relearn what you've already learnt

4096 is as far as it can get... i think its because of a flaw or restriction in the file, as trying to go further didn't crash, it just thought for a second, and nothing changed... Other than that, great, a long way out they look like continents on a 2d map

oh yeah i don't think flash allows you to go past a certain bitmap res for fear of eating to much ram. Ill find a way around it.

That's pretty neat, but it would be more fun if you could somehow control land generation. Then you could make a game out of it...

Yes next version i'm going to add customization than some viewing options. I'm also working on a tile based engine for this that could be used for a game.
