Behind-View Battle System

http://gamesvts.org​

I) Giới thiệu:
Được cải tiến từ Simple Side-View của Jet, Behind-View Battle System cho phép sử dụng Characters trong những trận chiến với góc nhìn từ phía sau. Điều thú vị này đã khắc phục được tính đơn điệu của Default Battle System ngày trước

II) Hướng dẫn sử dụng:
- Plug-n-play
- Xem kĩ phần chữ màu xanh (Giới thiệu và hướng dẫn) ở đầu đoạn mã trước khi dùng

III) Screenshots & Example:
