我最近一直在寻找程序生成的地形游戏。我看到柏林噪音对这个有用,所以我试了一下。到目前为止,地形生成得非常漂亮。然而,每当我运行程序多次,地形是完全相同的。有没有办法随机产生的柏林噪声?在
代码:
from opensimplex import OpenSimplex
import random
from time import time
height = 40
width = height
scale = height / 10
value = [[0 for x in range(width)] for y in range(height)]
gen = OpenSimplex()
def noise(nx, ny):
# Rescale from -1.0:+1.0 to 0.0:1.0
return gen.noise2d(nx, ny) / 2.0 + 0.5
def printBiome(y, x):
if value[y][x] <= 2:
print('O', end = " ")
elif value[y][x] >= 8:
print('M', end = " ")
else:
print('L', end = " ")
for y in range(height):
for x in range(width):
nx = x/width - 0.5
ny = y/height - 0.5
value[y][x] = 10 * noise(1 * scale * nx, 1 * scale * ny) + 0.5 * noise(2 * scale * nx, 2 * scale* ny) + 0.25 * noise(4 * scale * nx, 4 * scale * ny)
for y in range(height):
for x in range(width):
printBiome(y, x)
print()
OpenSimplex类defaults to using ^{} 。要生成不同的地形,请输入不同的种子值:
