TerrainData Inherits from Object

The TerrainData class stores heightmaps, detail mesh positions, tree instances, and terrain texture alpha maps.

The Terrain component links to the terrain data and renders it.

Variables

heightmapWidth	Width of the terrain in samples (Read Only).
heightmapHeight	Height of the terrain in samples (Read Only).
heightmapResolution	Resolution of the heightmap
heightmapScale	The size of each heightmap sample
size	The total size in world units of the terrain
wavingGrassStrength	Strength of the waving grass in the terrain.
wavingGrassAmount	Amount of waving grass in the terrain.
wavingGrassSpeed	Speed of the waving grass.
wavingGrassTint	Color of the waving grass that the terrain has.
detailWidth	Detail width of the TerrainData.
detailHeight	Detail height of the TerrainData.
detailResolution	Detail Resolution of the TerrainData.
detailPrototypes	Contains the detail texture/meshes that the terrain has.
treeInstances	Contains the current trees placed in the terrain.
treePrototypes	The list of tree prototypes this are the ones available in the inspector.
alphamapLayers	Number of alpha map layers
alphamapResolution	Resolution of the alpha map.
alphamapWidth	Width of the alpha map.
alphamapHeight	Height of the alpha map.
baseMapResolution	Resolution of the base map used for rendering far patches on the terrain
splatPrototypes	Splat texture used by the terrain.

Functions

GetHeight	Gets the height at a certain point x,y
GetInterpolatedHeight	Gets an interpolated height at a point x,y
GetHeights	Get an array of heightmap samples..
SetHeights	Set an array of heightmap samples.
GetSteepness	Gets the gradient of the terrain at point .
GetInterpolatedNormal	Get an interpolated normal at a given location.
SetDetailResolution	/detailResolution/ specifies the number of pixels in the detail resolution map. A larger detailResolution, leads to more accurate detail object painting.
RefreshPrototypes	Reloads all the values of the available prototypes (ie, detail mesh assets) in the TerrainData Object.
GetSupportedLayers	Returns an array of all supported detail layer indices in the area.
GetDetailLayer	Returns a 2D array of the detail object density in the specific location.
SetDetailLayer	Sets the detail layer density map.
GetAlphamaps	Returns the alpha map at a position x, y given a width and height
SetAlphamaps	Assign all splat values in the given map area.

Inherited members

Inherited Variables

name	The name of the object.
hideFlags	Should the object be hidden, saved with the scene or modifiable by the user?

Inherited Functions

GetInstanceID	Returns the instance id of the object.
ToString	Returns the name of the game object.

Inherited Class Functions

operator bool	Does the object exist?
Instantiate	Clones the object original and returns the clone.
