Get Height

This is the best I could come up with looking at how foreground sprites are placed. It does not work, and prints errors but I think it is the correct method. Any chance you could correct the code or offer your own solution?


  public static float terrainHeight(Vector3 pos)

  {

     HoneyFramework.Chunk c = HoneyFramework.Chunk.WorldToChunk(pos);

     if(c == null)

     {

        Debug.LogError("Could not find height from pos: ");

        Debug.LogError(pos);

        return 0;

     }



     Vector2 uv = c.GetWorldToUV(pos);

     if (uv.x > 0.0f && uv.x <= 1.0f && uv.y > 0.0f && uv.y <= 1.0f)

     {

        HoneyFramework.Vector2i textureUV = new HoneyFramework.Vector2i((int)((1 - uv.x) * c.height.width), (int)((1 - uv.y) * c.height.height));

        Color heightColor = c.height.GetPixel(textureUV.x, textureUV.y);

        //if (heightColor.a > 0.495f && heightColor.a < 0.75f)

        {

           return (heightColor.a - 0.5f) * 2f - 0.02f;

        }

     }

     Debug.LogError("Could not find height from pos: ");

     Debug.LogError(pos);

     return 0;

  }

I can't believe I missed that. Thank you.  But after trying to use it, I don't think it works...  I am trying to place some prefabs on Hex tiles and put them in the center of the tile, but at the correct height (especially important for mountains).   If the tile was 100% flat, you should only be able to see the top half of the sphere, but as you can see from the screen shot the height being returned is a little off (I think its always too high, never too low).





The grey sphere is not even touching the terrain (it should nestled in that hill). The pink sphere in the distance is kinda hovering above where it should be.



  public static bool placeResourceOnHex(HoneyFramework.Hex h, Resource.Type type)

  {

     if(type == Resource.Type.NONE || !HexHelper.canPlaceResourceOnHex (h, type))

        return false;

     

     GameObject prefab = Instantiate(Resources.Load("Prefabs/ResourceTypes/" + type.ToString())) as GameObject;

     Vector3 pos = HoneyFramework.HexCoordinates.HexToWorld3D(h.position);


     // THIS DOES NOT SEEM TO BE WORKING
     pos.y = HoneyFramework.World.GetWorldHeightAt(h.position);

     prefab.transform.position = pos;





     bool removedForgroundObject = false;

     for(int i = 0; i < h.foregroundData.Count; i++)

     {

        HoneyFramework.ForegroundData fgd = h.foregroundData[i];

        if (prefab.GetComponent<SphereCollider> ().bounds.Contains (fgd.position))

        {

           h.foregroundData.Remove(fgd);

           i--; // adjust for removal

           removedForgroundObject = true;

        }

     }



     return removedForgroundObject;

  }
Is there a bug in your World.GetWorldHeightAt function, or am I using it incorrectly?

I haven't seen this issue anywhere but i will check it during this moth dev.
