从Golang的父级实现方法中调用子级方法

Tick()

behavior.go

type IBehavior interface {
  Tick() Status
  Update() Status
}

type Behavior struct {
  Status Status
}

func (n *Behavior) Tick() Status {
  fmt.Println("ticking!")
  if n.Status != RUNNING { n.Initialize() }
  status := n.Update()
  if n.Status != RUNNING { n.Terminate(status) }

  return status
}

func (n *Behavior) Update() Status {
  fmt.Println("This update is being called")
  return n.Status
}

Behavior

type IBehaviorTree interface {
  IBehavior
}

type BehaviorTree struct {
  Behavior

  Root IBehavior
}

func (n *BehaviorTree) Update() Status {
  fmt.Printf("Tree tick! %#v
", n.Root)
  return n.Root.Tick()
}

A few more files to make this example make sense:

type ILeaf interface {
  IBehavior
}

type Leaf struct {
  Behavior
}

And this one:

type Test struct {
  Leaf

  Status Status
}

func NewTest() *Test {
    return &Test{}
}

func (n Test) Update() Status {
    fmt.Println("Testing!")
    return SUCCESS
}

And here is an example of its usage:

tree := ai.NewBehaviorTree()
test := ai.NewTest()
tree.Root = test

tree.Tick()

I was expecting the tree to tick normally by printing this:

ticking!
Tree tick!

But instead I'm getting:

ticking!
This update is being called

Could anyone help me with this issue?

Edit: Added a few extra files to illuminate the issue. Also, I don't understand the downvotes. I have an honest go question. Am I only supposed to ask questions that make sense to me already?
