我需要一些帮助来设置特定的地形。我有一个 200x200 补丁的世界,每个补丁的大小为 2 像素。我正在尝试做的是从原点开始建造一座小山,然后将高度均匀地分布到世界的边缘。
原点大约有最高海拔:999,边缘周围的补丁的高度接近0。从世界的边缘,高度应该不断增加,直到它到达原点但是,我似乎不能让山丘延伸到世界的边缘 - 中间有一个小凸起,世界其他地方完全平坦。
任何人都可以帮助设置地形并解释如何使高度正确扩散吗?
这是我到目前为止的代码:
patches-own [altitude]
to setup
clear-all
ask patch 0 0 [set altitude 1.0]
repeat 100 [diffuse altitude 0.25] ;; this needs to be changed?
scale-patches
color-patches
end
to scale-patches
let low [altitude] of min-one-of patches [altitude] ;; altitude of the lowest patch
let high [altitude] of max-one-of patches [altitude] ;; altitude of the highest patch
let range high - low ; difference from lowest to highest
ask patches [
set altitude altitude - low ; Shift every patch down so lowest altitude is 0
set altitude altitude * 999.0 / range ; Scale every patch so that the lowest is 0 and highest is 999
]
end
to color-patches
ask patches [set pcolor scale-color green altitude 0 1000]
end
