NullRefernceException

Code (CSharp):

1.  
2. int TerrainOffset_X = Width * SingleTerrainSize;
3.                         int TerrainOffset_Z = Height * SingleTerrainSize;
4.                        
5.                         // Terraincreation
6.                             Terrain NewTerrain = new Terrain();
7.                        
8.                         // TerrainInfo
9.                             NewTerrain.transform.position = new Vector3(TerrainOffset_X, 0, TerrainOffset_Z);
10.                             NewTerrain.transform.rotation = Quaternion.identity;
11.  
12.                        
13.  // Terraindata
14.                             TerrainData NewData = new TerrainData();
15.                             NewData.heightmapResolution = SingleTerrainHMSize;
16.                             NewData.size = new Vector3(SingleTerrainSize, TerrainMaxHeight, SingleTerrainSize);
17.                             NewData.baseMapResolution = 1024;
18.  
19.                        
20. // Add Data to Terrain
21.                             NewTerrain.terrainData = NewData;
22.  

Now my Question:

Why leads

NewTerrain.transform.position = new Vector3(TerrainOffset_X, 0, TerrainOffset_Z)

to a NullReferenceException??

All Variables have a value and it should (?!) work.

 

You can't "new" anything that's a Behaviour; that class doesn't work that way. You have to create a GameObject, then attach a Terrain component to it using AddComponent<Terrain>.

 

Wait. So I don't need to add a new Terrain, i need to add a new Gameobject and asign a Terrain to it?
