Hello all,
I am at the moment building a top-down 2d tile rpg like game. I am currently rendering from a set map defined in a seperate file. I would like to be able to generate a world so it looks realistic but generates fast and is easy to add to later (e.g. add more tiles later to generate in subsequent updates). I have heard of perlin noise generation, but would to know your advice and how i can use it
Max
Anyone?
Maybe you should change the title to:
[Help] Perlin Noise for 2d tile game
Anyhow, I hope this link helps you 
Thanks, I have done this but could not find how to actually apply it to generating tiles
On the http://mrl.nyu.edu/~perlin/noise/ source, when you run the method noise what do you do with the double it returns?
Done that 
Well, this link led me to this:
But I’m sure someone here knows a lot about this, let’s hope that with the new title experts come in I’m also interested in this.
Thanks so much
You’re welcome
By the way, please share your progress, I’d like to know how you implement it
Will do. Trying it out now
I can generate noise now well , but I still can’t work out how to interpret it to generate biomes and terrain? Any ideas?
once you generate noise, you did 99% of the work, just loop the pixels and test for case
if(pixelValue > 0x888888)
place mountain
if(pixelValue < 0x888888)
place grass
Thats just a very basic way, there are many ways, just be creative
edit: for biomes if going from mountains to plains change your values
if(pixelValue > 0xEEEEEE)
place hill
if(pixelValue < 0xEEEEEE)
place grass
depending on your perlin noise generation, you may have to create multiple noises depending on the feature (trees)
height and trees would have to be seperate 2d noises, or you could do a 3d noise and make trees be the alpha, there is lots of ways
Thanks
