Question

JavaScript => public function SetHeights(xBase: int, yBase: int, heights: float[,]): void;
C# => public void SetHeights(int xBase, int yBase, float[,] heights);

Parameters 参数

xBase	First x index of heightmap samples to set. 设置高度图的索引x。
yBase	First y index of heightmap samples to set. 设置高度图的索引y。
heights	Array of heightmap samples to set (values range from 0 to 1, array indexed as [y,x]). 设置采样高度图的数组(值范围0~1，数组索引作为[x,y])。

Description 描述

Set an array of heightmap samples.
设置采样高度图的数组。

Sets heightmap data using a two dimensional array of heightmap samples. The samples are represented as float values ranging from 0 to 1. The area affected is defined by the array dimensions and starts at xBase and yBase. The heights array is indexed as [y,x].
高度图数据设置为采样高度图的二维数组。该采样是个在0~1之间的值。该区域受到二维数组和起始位置x和y的影响。该高度数组索是个二维数组。

This method recomputes all the LOD and vegetation information for the terrain on each call, which can be computationally expensive. In interactive editing scenarios, it may be better to call TerrainData.SetHeightsDelayLOD instead, followed by Terrain.ApplyDelayedHeightmapModification when the user completes an editing action.
每次调用该方法重计算所有的LOD和每个地形的植物信息，该方法消耗大量的性能。在交互式的编辑场景中，当用户完成编辑操作时，它可能更好的调用TerrainData.SetHeightsDelayLOD，其次是Terrain.Apply-DelayedHeightmapModification。
