用英语玩得开心怎么说

To have fun in English, you can say "I'm having a great time!" or "I'm having a blast!" If you want to be more specific about what you are doing, you can say "I'm having fun playing this game," or "I'm enjoying myself at this party." You can also use words like "entertaining," "amusing," or "enjoyable" to describe something that is making you happy. For example, you could say "This movie is really entertaining" or "This book is very enjoyable."
