000F6F600FF - medium - this is the base test seed.
Hello, I’m posting the results of further seed observation, expanding on the previous post.
This is speculation based on observation. No code was de-compiled.
The structure
[00] - [0F6F] - [6] - [00] - [FF]
[A]----[B]--------[C]—[D]—[E]
A: Perlin noise minor: aka bumpiness. 00 = smooth terrain, FF = bumpy terrain. The effect is fairly minor but it can create or remove land bridges to your island or create some mineral spawn points on a flat map.
B: The seed. 16x16x16x16 = 65,536 possible perlin noise maps.
C: The biome. 1=Plains, 2=Lakes, 3=Alpine, 4=Arid, 6=Ideal. 0 seems to create a hidden biome that seems to be somewhere between plains and arid so I’ll call it the Dustbowl. 5 creates a hidden biome that might be called the Badlands. it has no fertility and all plant and animal resources are replaced with mineral resources. Any number higher than 6 gets set to 6 when you press enter on the seed or start the game, so all values higher than 6 are functionally 6.
The map is mostly the same across biomes, but there does seem to be some modification:
Dustbowl: modifies A and E. Reduces water level and bumpiness.
Plains: modifies A a lot. Things are much more smoothed than usual.
Lakes: modifies E a bit. The world is a bit more flooded than usual.
Alpine: modifies A and E. The world is bumpier and the water level is lower.
Arid: modifies A and E. Reduces water level and raises bumpiness.
Badlands: modifies E. Reduces water level a lot.
Ideal: no modifications, this was the baseline.
D: Perlin noise major: This value steps the perlin noise animation forward or backward. On this map, the mountain seems to be moving along the horizantal (X) axis, but it may be on both axis and it just happens that this time the mountain moves east-west. For a visual example, click here. To understand how the motion works click here.
E: Sea Level: FF = a flooded world, 00 = a dry world, 77 = an average world. these would be the dark areas of the perlin noise animation while the mountains would be the light areas.
So, the tldr is A, the first two digits, will help to get minerals or add/remove land bridges (at the cost of ease of building) and E (the 8th and 9th) will move terrain features. the 8th will move them a lot (16 steps per digit) while the 9th will nudge them (1 step per digit). the same is true for the last two digits, E, water level.
The example seed is a modified version of the second seed found here. If you move the mountain +120 steps using D you’ll get a nice turtle island similar to the original post but smoother. You can adjust it so that the entrance to the island is on the east side instead of the north side leading directly to vast riches just past the choke point. So you have a challenge with a reward if you’ve been following along. can you create that seed? (hint, don’t move the mountain out of reach).
Understanding hex
a single hex digit is 16 characters: [0123456789ABCDEF] but they are often used in pairs. the hex value of a color might be [5D] [78] [1F] or R,G,B (red, green, blue) with each pair offering 256 possible values. If you take the non-hex normal number 10 and change it to 20, you’ve increased the value by 10, In the same way, if you take the hex number B0 and change it to C0, you’ve increased the value by 16. changing B0 to B1 increases the value by 1 as usual. changing BB to BC also increases the value by 1. Finally, changing 5F to 60 is also an increase of 1.
hex [00] = 0 and hex [FF] = 255.
