Unity 笔记

unity的物件分static 和 dynamic

  • 摘要：任何拥有collider component 的都最好加上Rigidbody
  • 细节：出于性能考虑，但没有Rigidbody 的物件都认为是static，因为unity认为该物件不需要运动，并把全部static物件cache，如果写script让其运动却不赋予RigidBody，则per frame都要重新计算全部static物件到cache，影响性能，所以赋予Rigidbody给所有运动的物体让unity cache一次所有static物件，不需要重复刷新cache

elsonwu / mongodb_collection_sizes.js
Created January 11, 2018 07:40 — forked from joeyAghion/mongodb_collection_sizes.js
List mongodb collections in descending order of size. Helpful for finding largest collections. First number is "size," second is "storageSize."
var collectionNames = db.getCollectionNames(), stats = [];
collectionNames.forEach(function (n) { stats.push(db[n].stats()); });
stats = stats.sort(function(a, b) { return b['size'] - a['size']; });
for (var c in stats) { print(stats[c]['ns'] + ": " + stats[c]['size'] + " (" + stats[c]['storageSize'] + ")"); }

第三方应用验证流程

约定：

app: 代表第三方应用

server: 代表api服务器

申请token

  • 申请一个app时会得到client_id和secret_key，这个secret_key只有app和server知道
