How can I get the metadata from Terrain3DTextureAsset in c#

How can I retrieve the metadata of a Terrain3DTextureAsset in C#?

I would like to retrieve the metadata of the Terrain3DTextureAsset after touching Terrain3D with rayCast3D.

My current code

If you can help me, that would be great.

Assuming you have access to the Terrain3D node:

 var someData = Terrain3D.Get("assets").As<Resource>().Call("get_texture", textureIdx).As<Resource>().Get("whatever you want");

The full API is available to all languages, including C#, though there are hoops to jump through due to lack of bindings. https://terrain3d.readthedocs.io/en/latest/docs/programming_languages.html

These API pages provide the programmatic path to all variables, as demonstrated by TheOrioli's code.

For completeness, I think what is missing from all of the answers in regard to the question is to use the raycast and if the terrain is hit, call get_texture_id(hit_position). From there the Terrain3DTextureAsset can be looked up to retrieve whatever meta data is desired. The extended class info below is interesting and valuable. Familiarity with the API and the C# hoops are also necessary.

Personally, I've made this extended GDScript class that wraps around the regular TerrainTexture

class_name Terrain3DDataTexture
extends Terrain3DTextureAsset

const TD := preload("res://game/dungeons/dungeon_terrain/terrain_data/DungeonTerrainData.cs")

@export var data : TD

which lets me create my own custom data objects that are typesafe in C#
It looks like this in Godot:

I triedI tried but I get the error “Line 6:Export type can only be built-in, a resource, a node, or an enum.”

[TheOrioli]

That depends on what your TerrainData script is. I'm also not sure how Godot handles directory names with special characters like '#', so I would avoid that.

If it looks something like this it should work, and problem is probably specific to your project

using Godot;


[GlobalClass]
public partial class DungeonTerrainData : Resource
{
    [Export(PropertyHint.Range, "0,1")] public float Friction { get; private set; } = 0.0f;
}
