Here is the deal:

extends MeshInstance

func _ready():

  var st = SurfaceTool.new()


  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))


  var my_mesh = Mesh.new()

  $Surface_Tool_Triangle.mesh = my_mesh

SurfaceToolTriangle 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'.
