面向 Cloud Code 的 Cloud Save 教程

从 Cloud Code 访问 Cloud Save

const _ = require("lodash-4.17");const {  DataApi} = require("@unity-services/cloud-save-1.4");const NUMBER_OF_SIDES = 6;module.exports = async ({ params, context, logger }) => {  const {	projectId,	playerId  } = context;  const api = new DataApi(context);  const roll = rollDice(NUMBER_OF_SIDES);  if (roll > NUMBER_OF_SIDES) {    // Log an error message with information about the exception	logger.error("The roll is greater than the number of sides: " + roll);    // Return an error back to the client    throw Error("Unable to roll dice!");  }  // Return a JSON result to the client  const result = {	sides: NUMBER_OF_SIDES,	roll: roll,  };  const setResult = await api.setItem(projectId, playerId, {	key: "DIE_ROLL",	value: result  });  logger.debug(JSON.stringify(setResult.data));  return result;};// Function outside of the script wrapperfunction rollDice(sides) {  return _.random(1, sides);}

跨玩家数据

otherPlayerId

const { DataApi } = require('@unity-services/cloud-save-1.4');module.exports = async ({ params, context, logger }) => {  const { projectId } = context;  const { otherPlayerId } = params;  // Initialize the cloud save API client  const cloudSaveAPI = new DataApi(context);  // Access the save data for the specified player  const otherPlayerSave = await cloudSaveAPI.getItems(    projectId,    otherPlayerId, // or any other player ID    "likes" // Cloud Code key  );  // Assume that player's likes is 0 if the key doesn't exist  const otherPlayerLikes = otherPlayerSave.data.results[0]?.value || 0;  // Update the data for the specified player  cloudSaveAPI.setItem(    projectId,    otherPlayerId, { key: "likes", value: otherPlayerLikes + 1 }  )};
