簡易的回合制多人遊戲系統 - 透過 Parse

TurnBasedGame 資料表設計

欄位	類型	解釋	範例
objectId	String	遊戲 ID，供辨識使用	${GAME ID}
Participants	Array	玩家清單	[${USER ID},...]
CurrentPlayer	String	當前回合玩家	${USER ID}
NextDeadline	Number	當前回合玩家的期限	${UNIX TIMESTAMP}
GameData	Object	遊戲資料	${GAME DATA}
GameStatus	String	遊戲狀態	Active Finish...

• 配對系統 建立遊戲資料表

curl -X POST \
-H "X-Parse-Application-Id: ${APPLICATION_ID}" \
-H "X-Parse-REST-API-Key: ${REST_API_KEY}" \
-H "Content-Type: application/json" \
-d '{"Participants":[${USER_OBJ_A}...],"CurrentPlayer": ${USER_ID_A},"NextDeadline":${TIMESTAMP},"GameData":${DATA_OBJ},"GameStatus":"Active"}' \
https://YOUR.PARSE-SERVER.HERE/parse/classes/TurnBasedGame

• 透過 Cloud Code 系統推送 換手 通知給特定玩家

可在 Installation 與 User 中互相綁定資料，用來作 Target Segmentation

var query = new Parse.Query(Parse.Installation)
query.equalTo('user', {'__type': 'Pointer', 'className': 'User', 'objectId': ${USER ID}})
Parse.Push.send({
  where: query,
  data: {
    alert: 'TURN'
  }
}, { useMasterKey: true }).then(
  function () {
    response.success()
  },
  function (error) {
    response.error(error)
  }
)

• 任意玩家可隨時取得最新 遊戲資料表

curl -X GET \
  -H "X-Parse-Application-Id: ${APPLICATION_ID}" \
  -H "X-Parse-REST-API-Key: ${REST_API_KEY}" \
  -G \
  --data-urlencode 'where={"objectId": ${GAME ID}}' \
  https://YOUR.PARSE-SERVER.HERE/parse/classes/TurnBasedGame

• 當局玩家進行該局遊戲，遊戲換手

curl -X PUT \
  -H "X-Parse-Application-Id: ${APPLICATION_ID}" \
  -H "X-Parse-REST-API-Key: ${REST_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"GameData":${GAME DATA},"CurrentPlayer": ${USER_ID_NEXT},"NextDeadline":${TIMESTAMP_NEXT}}' \
  https://YOUR.PARSE-SERVER.HERE/parse/classes/TurnBasedGame/${GAME ID}

• 當局玩家進行該局遊戲，賽局完成

curl -X PUT \
  -H "X-Parse-Application-Id: ${APPLICATION_ID}" \
  -H "X-Parse-REST-API-Key: ${REST_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{"GameData":${GAME DATA},"GameStatus": "Finish"}' \
  https://YOUR.PARSE-SERVER.HERE/parse/classes/TurnBasedGame/${GAME ID}

• 當局玩家完成遊戲後更新後，由 Cloud Code 監聽 afterSave 送出 換手 或是 完成遊戲 通知

Parse.Cloud.afterSave("TurnBasedGame", function (request) {
  if (request.object.get("GameStatus") === "Active"){
    // 發送通知：換手
  } else if (request.object.get("GameStatus") === "Finish"){
    // 發送通知：完成遊戲
  }
})
