[Unity3D Daily] Implement a timer and countdown tool

I. Introduction

Today I will share how to make a timer tool based on Unity3D. In order to facilitate the demonstration, UGUI Text is used. The code is simple and expandable. Then, if you have any errors or comments, please welcome me to put them forward. The WeChat QR code has been displayed on the blog homepage. If you want to communicate and learn, you can add it if you outsource the project.

Fourth, the code
