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.
| alphamapHeight | Height of the alpha map. |
| alphamapLayers | Number of alpha map layers. |
| alphamapResolution | Resolution of the alpha map. |
| alphamapTextures | Alpha map textures used by the Terrain. Used by Terrain Inspector for undo. |
| alphamapWidth | Width of the alpha map. |
| baseMapResolution | Resolution of the base map used for rendering far patches on the terrain. |
| bounds | The local bounding box of the TerrainData object. |
| detailHeight | Detail height of the TerrainData. |
| detailPrototypes | Contains the detail texture/meshes that the terrain has. |
| detailResolution | Detail Resolution of the TerrainData. |
| detailWidth | Detail width of the TerrainData. |
| heightmapHeight | Height of the terrain in samples (Read Only). |
| heightmapResolution | Resolution of the heightmap. |
| heightmapScale | The size of each heightmap sample. |
| heightmapWidth | Width of the terrain in samples (Read Only). |
| size | The total size in world units of the terrain. |
| splatPrototypes | Splat texture used by the terrain. |
| thickness | The thickness of the terrain used for collision detection. |
| treeInstanceCount | Returns the number of tree instances. |
| treeInstances | Contains the current trees placed in the terrain. |
| treePrototypes | The list of tree prototypes this are the ones available in the inspector. |
| wavingGrassAmount | Amount of waving grass in the terrain. |
| wavingGrassSpeed | Speed of the waving grass. |
| wavingGrassStrength | Strength of the waving grass in the terrain. |
| wavingGrassTint | Color of the waving grass that the terrain has. |
| GetAlphamaps | Returns the alpha map at a position x, y given a width and height. |
| GetDetailLayer | Returns a 2D array of the detail object density in the specific location. |
| GetHeight | Gets the height at a certain point x,y. |
| GetHeights | Get an array of heightmap samples. |
| GetInterpolatedHeight | Gets an interpolated height at a point x,y. |
| GetInterpolatedNormal | Get an interpolated normal at a given location. |
| GetSteepness | Gets the gradient of the terrain at point (x,y). |
| GetSupportedLayers | Returns an array of all supported detail layer indices in the area. |
| GetTreeInstance | Get the tree instance at the specified index. It is used as a faster version of treeInstances[index] as this function doesn't create the entire tree instances array. |
| RefreshPrototypes | Reloads all the values of the available prototypes (ie, detail mesh assets) in the TerrainData Object. |
| SetAlphamaps | Assign all splat values in the given map area. |
| SetDetailLayer | Sets the detail layer density map. |
| SetDetailResolution | Set the resolution of the detail map. |
| SetHeights | Set an array of heightmap samples. |
| SetHeightsDelayLOD | Set an array of heightmap samples. |
| SetTreeInstance | Set the tree instance with new parameters at the specified index. However, TreeInstance.prototypeIndex and TreeInstance.position can not be changed otherwise an ArgumentException will be thrown. |
| hideFlags | Should the object be hidden, saved with the scene or modifiable by the user? |
| name | The name of the object. |
| GetInstanceID | Returns the instance id of the object. |
| ToString | Returns the name of the game object. |
| Destroy | Removes a gameobject, component or asset. |
| DestroyImmediate | Destroys the object obj immediately. |
| DontDestroyOnLoad | Makes the object target not be destroyed automatically when loading a new scene. |
| FindObjectOfType | Returns the first active loaded object of Type type. |
| FindObjectsOfType | Returns a list of all active loaded objects of Type type. |
| Instantiate | Clones the object original and returns the clone. |
| bool | Does the object exist? |
| operator != | Compares if two objects refer to a different object. |
| operator == | Compares two object references to see if they refer to the same object. |
