In past answers to similar questions, I have seen the stated answers being that []Fight and []IReset are not the same type, and there is no support for automatically converting from one to the other, and it will not treat the slice of concrete types as the slice of IReset interfaces because of a difference in memory layout.
Basically I think you would need to make([]IReset) and then type assert when setting the fields: https://play.golang.org/p/xceK0aoTvQ Justin On Tue, Jan 24, 2017 at 2:47 PM hui zhang <fastfad...@gmail.com> wrote: > check code below, How to use []interface{} in generic programing? > > type IReset interface { > Reset() > } > type Fight struct { > hp,mp int > } > func (my *Fight) Reset () { > my.hp = 0 > my.mp = 0 > } > func reset1(x IReset){ > x.Reset() > } > func reset(x []IReset) { > for i := range x { > x[i].Reset() > } > } > func Reset() { > arr := make([]Fight,1) > arr[0].hp = 100 > reset1(arr[0])//OK > reset(arr)// can not use []Fight as []IReset > } > > > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
