Question

Android

Hi all. How can you make a game engine for a game like HayDay or Clash of Clans on android? What programs and technologies will be needed for this? Does anyone have a principle or materials for creating a game engine for Android? Thanks

Answer 1

Write your own unity engine.
As a core technology, a lot of geometry and some matan for shadows, effects and optimization.

Answer 2

My advice is to not go for game development in android without any engine.
It is extremely complex to develop game with pure android and java.
