= and == 注意，在if語句中，必須使用==，因為=用于為變量賦值。 此外，您正在處理布爾運算，因此可以執行以下操作： if (checkBedDraw) { typePrint("You have already checked the drawers, and aqcuired a picklock.", 50);} else { clear(); typePrint("You found a \u001b[34mpicklock\u001b[0m! you can only use this on a specific lock, because of its shape. This item has been added to your \u001b[31minventory\u001b[0m.", 50); invArray[0] = "picklock"; checkBedDraw = true;}
