Impela, ake singene nzulu odabeni lwephutha C4840 kuhlelo lwe-C++ nesixazululo salo.
Iphutha elingu-C4840 ku-C++, ngokuvamile livela uma kukhona ukusetshenziswa okungaphatheki kwekilasi elithi 'FString' njengengxabano yomsebenzi ohlukile. Lokhu kungaholela ezinkingeni ezehlukene ezihlanganisa amaphutha ohlanganisela kanye nokuziphatha kohlelo okungalindelekile. Ukuqonda nokuxazulula le nkinga kuyisihluthulelo sokugcina ikhodi ephumelelayo nephumelelayo.
Isixazululo sephutha i-C4840 sizungeza kakhulu ekusebenziseni isigaba se-FString ku-agumenti yomsebenzi ohlukile. Imisebenzi ehlukahlukene iyimisebenzi eyamukela inani elihlukile lama-agumenti. Isigaba se-FString ku-Unreal Engine sisetshenziswa ngokuyinhloko ekuguquleni umbhalo, futhi ukusetshenziswa kwaso okungaphatheki kuhlobene nemizamo yokuyisebenzisa ngaphakathi kokuqukethwe noma izinkundla obungahloselwe zona.
// Ukusetshenziswa okulungile:
FString MyString = UMBHALO(“Sawubona, Umhlaba!”);
// Ukusetshenziswa okungalungile okuholela ephutheni C4840:
SomeVariadicFunction(“Sawubona, Umhlaba!”);
Imisebenzi ye-FString kanye ne-Variadic
Iphuzu eliyinhloko okufanele uliqonde lapha ukuthi i-FString kufanele isetshenziswe ngendlela efanele ngokuphathelene nemisebenzi ehlukahlukene. I-FString yenzelwe ukuthi ikwazi ukuphatha kanye nokukhohlisa umbhalo ngaphakathi komongo we-Unreal Engine. Ngakolunye uhlangothi, imisebenzi ehlukahlukene iyisici se-C++, nezinye izilimi, ezivumela umsebenzi ukuthi uphathe inombolo eguquguqukayo yama-agumenti.
Kodwa-ke, uma i-FString isetshenziswa njengempikiswano yomsebenzi ohlukile, lokhu kungaholela ephutheni C4840.
Uligwema Kanjani Iphutha C4840
Ukuze ugweme Iphutha C4840, umuntu kufanele aqinisekise ukuthi ukuguqulwa okufanele kwenzeka ngaphambi kokudlulisa isibonelo se-FString kumsebenzi we-variadic. Nansi indlela ongakwenza ngayo:
#faka phakathi okuthi “Misc/Printf.h”
FString MyString = FString::Printf(TEXT(“Sawubona %s”), *AnotherString);
Kulesi sibonelo esichazwe ngenhla, sigwema iphutha ngokuguqula i- AnotherString isuka ku-FString iye ku-TCHAR yesikhombi samalungu afanayo sisebenzisa i-opharetha ethi '*' engajwayelekile.
Lokhu kusiletha esikhumbuzweni esibalulekile: noma yiluphi uhlobo lokuqondisa noma ukusetshenziswa okungaphatheki kwe-FString njengempikiswano yokusebenza kwe-variadic ngokuvamile umlandu wephutha C4840. Ngakho-ke, kubalulekile ukusebenzisa umkhuba wokuhlela olungile, njengoluhlobo oluboniswe esibonelweni esingenhla.
Isiphetho nezincomo
Ukuqonda uhlobo lwephutha C4840 kanye nokusetshenziswa okufanele kwe-FString nemisebenzi ehlukahlukene kubalulekile ukuze kugwenywe izinkinga ezinjalo esikhathini esizayo. Udinga ukukhumbula ifomethi efanele kanye nesidingo sokuguqulwa okufanele ngaphambi kokudlulisa izimo ze-FString kunoma yimuphi umsebenzi ohlukile, ngaleyo ndlela uqinisekise ukuthi uhlelo lwakho lwe-C++ luhlala luzwakala futhi lungenaphutha. Bese ukhumbula ukubaluleka kokuphatha izici zolimi ze-C++ kanye ne-Unreal Engine ukuze ube umhleli we-C++ osebenzayo futhi osebenza kahle.
Sengiphetha, khumbula i-mantra: "Ukusetshenziswa kahle kwe-FString, CHA ekusetshenzisweni okungaphatheki". Jabulela ukubhala ngekhodi!
