Use GDScript to create collision mesh for my procedural generated 3D terrain.

Question

Hello

I have generated a procedural 3d terrain with the SurfaceTool and now I want to add collision to it. Before 3.1 I could use "createtrimeshcollision/createconvexcollision" to generate one but after 3.1 i get that "Method 'createtrimeshcollision' is not declared in the current class".

Do any of you know how I can generate a collision mesh to my procedural terrain using GDScript?

These methods still exist for Meshinstance:
https://docs.godotengine.org/en/3.1/classes/class_meshinstance.html

Does that help?

Thats how I'm using it. But gets the above error.

I used MeshInstance.createtrimeshcollision(), jsut today, and it worked well:

var meshInst = MeshInstance.new()
st.begin(Mesh.PRIMITIVE_TRIANGLES)
.
.#adding vertices, uvs and stuff to SurfaceTool
.
meshInst.mesh = st.commit()
meshInst.create_trimesh_collision()

In this code the MeshInstance itself was created in code too, but you can use an existing MeshInstancetoo, of course
