无法将数字解组为Go Value

Question

I try to refrain from asking questions with simple answers but I can't seem to figure out what the issue is here... (Issue in title)

Relevant code:

match := new(Match)
if _, msgB, err = ws.ReadMessage(); err != nil {
    panic(err)
}else {
    println(string(msgB))
    err = json.Unmarshal(msgB, match)

    if err != nil { panic(err) }
}


type Match struct {
    Teams [][]Char
    Map [][]Tile
    ID string //uuid
    Socket *websocket.Conn `json:'-'`
}
type Char struct {
    ID int
    HP int
    CT int
    Stats statList 
    X int
    Y int
    ACList Actions
}
type statList struct {
    Str int
    Vit int
    Int int
    Wis int
    Dex int
    Spd int
}
type Actions struct {
    Actions []Action
    TICKCT int
}

String to unmarshal (Formatted for visibility):

Error:

2014/03/28 12:11:41 http: panic serving 127.0.0.1:56436: json: cannot unmarshal number into Go value of type main.Char

Answer 1

I made a fixed version of the code (playground). This seemed to be the main mistake:

type Char struct {
    ID     int
    HP     int
    CT     int
    Stats  []int // This was statList which won't work
    X      int
    Y      int
    ACList Actions
}

Also note the definition I made of Tile which allows numbers to be nil.

type Tile struct {
    Depth int
    Type  int
    Unit  *int
}

You didn't provide all the structures so I made some up - probably wrong! All together that is:

import (
    "encoding/json"
    "fmt"
)

type Match struct {
    Teams [][]Char
    Map   [][]Tile
    ID    string //uuid
    //    Socket *websocket.Conn `json:'-'`
}

type Char struct {
    ID     int
    HP     int
    CT     int
    Stats  []int // This was statList which won't work
    X      int
    Y      int
    ACList Actions
}
type statList struct {
    Str int
    Vit int
    Int int
    Wis int
    Dex int
    Spd int
}
type Action string
type Actions struct {
    Actions []Action
    TICKCT  int
}

type Tile struct {
    Depth int
    Type  int
    Unit  *int
}
