# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
- master

pool:
  vmImage: 'windows-2019'

# make sure you have set variables for followings at AzureDevOps Pipeline Variable configuration UI.

#variables:
  #unity.username: YOUR_USER_NAME_AS_SECRET
  #unity.password: YOUR_USER_PASSWORD_AS_SECRET
  #unity.serialkey: YOUR_UNITY_SERIALKEY_AS_SECRET

steps:
- checkout: self
