Here is the deal:

extends MeshInstance


func _ready():

  var st = SurfaceTool.new()

  st.begin(Mesh.PRIMITIVE_TRIANGLES)

  st.add_normal(Vector3(0, 0, -1))
  st.add_color(Color(1, 0, 0, 1))
  st.add_vertex(Vector3(-1, 0, 0))

  st.add_normal(Vector3(0, 0, -1))
  st.add_color(Color(0, 1, 0, 1))
  st.add_vertex(Vector3(1, 0, 0))

  st.add_normal(Vector3(0, 0, -1))
  st.add_color(Color(0, 0, 1, 1))
  st.add_vertex(Vector3(0, 2, 0))

  st.add_index(0)
  st.add_index(1)
  st.add_index(2)

  var my_mesh = Mesh.new()
  st.commit(my_mesh)

  $Surface_Tool_Triangle.mesh = my_mesh

Surface_Tool_Triangle is a child of Spatial, root node

I wanted to create a simple mesh, but instead I got:

  Invalid set index 'mesh' (on base: 'null instance') with value of type 'ArrayMesh'.
