NPC 對話

這頁是對英文翻譯過來的。若兩篇無仝，以英文頁為準。看英文頁

你遊戲內底的角色會當用玩家咧學的語言佮伊開講，照伊的等級來調整。玩家講的逐句話就是一个回合：玩家套件共伊送出去，角色的回覆就一節一節串流轉來。

一个回合紮啥物

逐个回合攏會送角色需要的全部物件，因為 Lingara 佇回合中間袂保留任何對話：

npc：是啥人咧講話。伊的 name 是 1 到 32 个字元，伊的 persona（選填）是一逝描述，1 到 120 个字元，像「一个賣水餃的」。
scene：選填，對話發生的所在，1 到 160 个字元。
source_lang 佮 target_lang：玩家家己的語言，佮伊咧學的語言。兩个愛無仝，角色干焦講 target_lang。
level：玩家的等級，對 1 到 9。Lingara 的指南「等級的意思」有說明這个尺度。
line：玩家拄才講的話，1 到 500 个字元。
history：到這馬為止的對話，上舊的先，上濟 12 逝。逐逝有一个 speaker，是 player 抑是 npc，閣有伊的 text，1 到 500 个字元。

逐段文字攏是單一逝。對話由你的遊戲保管：玩家套件會為你開的逐个對話保留一个視窗，共逐个完成的回合加入去，共逐个回覆切做頭前 500 个字元，閣共超過 12 逝的上舊的逝提掉。

Lingara 共 persona 佮場景當做對你的遊戲來的、袂當信任的文字。這兩項會影響角色按怎講話，毋過永遠袂改變伊會當做啥物。

回覆按怎來

回覆是一節一節的文字串流過來，你的遊戲佇到的時共伊接起來。中間可能會有通知，像講回覆予人切斷矣。回覆完成的時，回合用 done 結束；失敗的時，用 error 結束。回合袂當接續：若連線斷去，玩家就愛閣講一擺彼句話。

對逐个角色一擺干焦講一句。角色猶咧回覆的時講的話會予人拒絕，袂排隊，因為逐个回合攏愛算錢。

啥人付錢

干焦計量用戶端的玩家會當開講，逐个回合攏算佇彼个用戶端的帳。玩家的權杖需要 embed:play。
