Spawn ON terrain

Hey there

I have following problem:
I wrote a spawnsystem and it works fine.
There is still one problem i can't solve yet:

How i can spawn enemys ON the terrain?
How i get the height of one point from the terrain?

I tried it with:

Code (csharp):

1. pos.y = Terrain.activeTerrain.terrainData.GetHeight();

but GetHeight only works for int variables and not for float (How it should).

Thanks for help

Did you read the docs on the terrain system or try raycasting?

 

Maybe:
GetInterpolatedHeight(x: float, y: float): float;
http://docs.unity3d.com/Documentation/ScriptReference/TerrainData.GetInterpolatedHeight.html

 

ok
no i didn't know this command, but now it doesn't work, too.

Code (csharp):

1. pos.y = Terrain.activeTerrain.terrainData.GetInterpolatedHeight(pos.x,pos.z);

this is my code for setting the "right" height.
pos is a vector3.

now: what is wrong whis this?

 

Oh, this is what you need to use:

Terrain.SampleHeight
http://docs.unity3d.com/Documentation/ScriptReference/Terrain.SampleHeight.html
Note that it is relative to the terrain position, so you may need to take that into account depending on your terrain height.

RIGHT!

Thank you very much!

 

Last time I looked, the terrain system docs were somewhat lacking, especially with heights and such. Been that way for a while. I can very much understand his confusion.

 

7 Years later and it still holds true... ;-) Thank you!
