在循环中修改结构

Question

我想遍历结构数组并修改每个项目。但是，以下代码中的结构尽管分配了新值，但仍保持相同。该代码可以正常编译。由于该结构是自引用的，因此我使用了指针。我不确定这是否会使以后的重新分配变得复杂。

package main
import "fmt"

type Actor struct {
    name string
    i    int
    bff  *Actor
}

func main() {
    var bob Actor
    bob.name = "Bob"
    bob.i = 10
    var sara Actor
    sara.name = "Sarah"
    sara.i = 20
    var john Actor
    john.name = "John"
    john.i = 30
    bob.bff = &sara
    sara.bff = &john
    john.bff = &bob

    actors := []Actor{bob, sara, john}

    for turn := 1; turn <= 3; turn++ {
        fmt.Println("----------Turn", turn, "----------")
        for _, actor := range actors {
            fmt.Println(actor.name, ":  i =", actor.i, "  bff=", actor.bff.name)
            if actor.bff == &john {
                actor.bff = &sara
            } else if actor.bff == &sara {
                actor.bff = &bob
            } else if actor.bff == &bob {
                actor.bff = &john
            }
            actor.i = actor.i + turn
        }
    }
}
