Ho lokisa morero oa SDL2 o tla sebetsa ho Android

Lumelang bohle. Kajeno re tla sheba mokhoa oa ho lokisa morero ho sebelisa laeborari ea sdl2 ho tsamaisa papali ho Android.

Pele o hloka ho jarolla Studio ea Android, ho e kenya le tsohle tse hlokahalang tikolohong ena ea nts'etsopele. Ka mohlala, hona joale ke na le Kde Neon, 'me tsamaisong ena ho na le faele /etc/tikoloho, faele e tšoanang e teng ho ubuntu. Lintlha tse latelang li hloka ho kenngoa moo.

U boetse u hloka ho khoasolla NDK webosaeteng ea semmuso, u e lokolle bukeng ea hau ea lapeng ebe u e reha NDK. E latelang o hloka ho khoasolla laebrari ea SDL2 webosaeteng libsdl.org. Ho sebelisa sdl2 bakeng sa android, ke habohlokoa hore u se ke ua e bokella bakeng sa k'homphieutha, hobane ka nako eo e ke ke ea bokella bakeng sa android. E le hore morero o kopane, o hloka ho theha morero ho android studio, mang kapa mang, ho amohela laesense, ho seng joalo SDL2 e tla kopa laesense ha u haha.

Ho bala lifaele ho android ho tsoa ho thepa, o hloka ho sebelisa ts'ebetso ea SDL_RWops. Mona ke mohlala oa tšebeliso ea khoutu bakeng sa ho sebetsa ka fonte. Tabeng ena, re ke ke ra sebelisa FT_New_Face, empa ho e-na le hoo, re tla sebelisa FT_New_Memory_Face ho sebelisa lintlha tse seng li baliloe.
