Installing Unity Hub and Unity

  • Install Unity Hub first.
  • Then install Unity.
    • Basically, follow the procedure on the official page below.
    • However, be careful when selecting “License Management” and “License agreement”. The functional differences of the plan are as follows.
    • The “Personal” plan is free to use, so we would like you to choose it as much as possible, but the qualification is for individuals or small and medium-sized enterprises. This means it’s available if your revenue or funding doesn’t exceed $ 100,000 a year for the last 12 months. Therefore, the only users who can select “Individual” in “License Management” are those who are “Less than $ 100,000” in “License Agreement”.

Setting Android application development / build environment by Unity

Unity can be used by the procedure so far. However, if you want to develop and release games, apps, etc. for a specific platform using Unity, additional steps are required.
As an example, we describe the procedure for building an environment that can build games and apps for terminals running Android OS such as smartphones using Unity.
