The Hong Kong Association for Computer Education (HKACE) successfully held an introductory session for the "Nintendo Switch Game Studio - From Player to Creator" course in collaboration with Una Technologies Limited. The session attracted numerous teachers and provided a unique platform for participants to learn game design and development from scratch through specially designed guided courses. Participants had the opportunity to play Nintendo Switch games, interact directly with experienced instructors, and gain in-depth knowledge of the hardware and software packages of the Nintendo Switch. This event not only helped teachers understand how to transform creativity into interactive games but also provided valuable feedback. Today's successful event demonstrates the tremendous potential of combining education and technology, offering teachers a valuable opportunity to transition from players to game creators.
