Resolved Random tree spawner

So I'm making a random tree spawner however, the trees are spawning outside of the terrain bounds. Any ideas as to what I need to change to fix this? Image of the current results is this https://flic.kr/p/2oeJqCu

Code (CSharp):

1. public class TreeSpawner : MonoBehaviour{
2.     public GameObject treePrefab, treeParent;
3.     public int treeAmount;
4.     List<GameObject> treesList = new List<GameObject>();
5.     GameObject[] treesArray;
6.  
7.     public GameObject Terrain;
8.  
9.     void Start(){
10.         Vector3 TerrainSize = Vector3.Scale(transform.localScale, Terrain.GetComponent<MeshCollider>().bounds.size);
11.      
12.         for (int i = 0; i <= treeAmount; i++){
13.             treesList.Add(Instantiate<GameObject>(treePrefab));
14.             treesArray = treesList.ToArray();
15.             treesArray[i].transform.position = new Vector3(Random.Range(TerrainSize.x ,TerrainSize.y), 0, Random.Range(TerrainSize.x, TerrainSize.y));
16.             treesArray[i].transform.parent = treeParent.transform;
17.         }
18.     }
19. }

 

Just look at your random range methods. The answer should be pretty obvious.

 

may or may not have forgotten how vectors work, thanks for the comment.
