Te whakarite kaupapa SDL2 hei whakahaere i runga i te Android

Kia ora katoa. I tenei ra ka titiro tatou me pehea te whakarite kaupapa ma te whakamahi i te whare pukapuka sdl2 hei whakahaere i tetahi keemu i runga i te Android.

Tuatahi me tango e koe te Android Studio, whakauruhia me nga mea katoa e hiahiatia ana i tenei taiao whanaketanga. Hei tauira, kei a au inaianei a Kde Neon, kei runga i tenei punaha he konae /etc/taiao, he rite tonu te konae kei ubuntu. Ko nga taurangi e whai ake nei me whakauru ki reira.

ANDROID_HOME=/home/username/Android/Sdk
ANDROID_NDK_HOME=/home/username/ndk

Me tango ano e koe te NDK mai i te paetukutuku mana, wetewetehia ki to raarangi kaainga ka whakaingoatia ki te NDK. I muri mai me tango e koe te whare pukapuka SDL2 mai i te paetukutuku libsdl.org. Hei whakamahi i te sdl2 mo te phi, he mea nui kia kaua e whakahiato mo te rorohiko, na te mea ka kore e whakahiato mo te phi. Kia whakahiato te kaupapa, me hanga e koe he kaupapa i roto i te taiwhanga phi, ahakoa tetahi, ki te whakaae ki te raihana, ki te kore ka tono raihana a SDL2 i te wa e hanga ana.

Hei panui i nga konae i te phi mai i nga rawa, me whakamahi koe i nga mahi SDL_RWops. Anei tetahi tauira o te whakamahi i te waehere mo te mahi me te momotuhi. I tenei take, kaore e taea e matou te whakamahi FT_New_Face, engari ka whakamahi FT_New_Memory_Face ki te whakamahi i nga raraunga kua panuitia.

#ifdef __ANDROID__
        snprintf ( path, 254, "fonts/%s", file );
        SDL_RWops *rw = SDL_RWFromFile(path, "r" );
        char *memory = ( char * ) calloc ( rw->hidden.androidio.size, 1 );
        SDL_RWread(rw, memory, 1, rw->hidden.androidio.size );

        FT_New_Memory_Face(*this->ft_library, ( const FT_Byte  * )memory, rw->hidden.androidio.size, 0, &this;->face );
        SDL_RWclose(rw);
        free ( memory );
#else
        snprintf ( path, 254, "%s/fonts/%s", DEFAULT_ASSETS, file );
        if ( access ( path, F_OK ) ) {
                fprintf ( stderr, "not found font: %sn", path );
                exit ( EXIT_FAILURE );
        }
        struct stat st;
        stat ( path, &st; );
        FILE *rw = fopen ( path, "r" );
        char *memory = ( char * ) calloc ( st.st_size, 1 );
        fread ( memory, 1, st.st_size, rw );

        FT_New_Memory_Face ( *this->ft_library, ( const FT_Byte * ) memory, st.st_size, 0, &this;->face );
        fclose ( rw );
        free ( memory );
#endif

I hanga ano e ahau he konae pane hei hono i nga pane SDL2. NO_SDL_GLEXT e hiahiatia ana mo te whakahiato kia angitu i runga i te Android.

#ifdef __ANDROID__
#include "SDL.h"
#include "SDL_video.h"
#include "SDL_events.h"
#define NO_SDL_GLEXT 
#include "SDL_opengl.h"
#include "SDL_opengles2.h"
#else
#include <SDL2/SDL.h>
#include <SDL2/SDL_video.h>
#include <SDL2/SDL_opengl.h>
#include <SDL2/SDL_opengles2.h>
#endif

Na kua reri te kaupapa, kua rite nga kaimarumaru mo Opengl Es 3.0. Inaianei me hanga e tatou he kaupapa phi. Hei mahi i tenei, wetewetehia te puranga SDL2. Haere ki te hanga-whakatuhi. A ka penei ta matou mahi.

./androidbuild.sh com.xverizex.test main.cpp

Ka puta te karere e whai ake nei.

To build and install to a device for testing, run the following:
cd /home/cf/programs/SDL2-2.0.10/build/com.xverizex.test
./gradlew installDebug

Haere ki com.xverizex.test. Haere ki com.xverizex.test/app/jni/src. Ka kape taatau kaupapa keemu. Na ka hurihia e matou te konae Android.mk, i taku keehi he penei te ahua.

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := main

SDL_PATH := ../SDL
FREETYPE_PATH := ../Freetype2

LOCAL_C_INCLUDES := $(LOCAL_PATH)/$(SDL_PATH)/include $(LOCAL_PATH)/$(FREETYPE_PATH)/include

# Add your application source files here...
LOCAL_SRC_FILES := ./engine/lang.cpp ./engine/actor.cpp ./engine/sprite.cpp ./engine/shaders.cpp ./engine/box.cpp ./engine/menubox.cpp ./engine/load_manager.cpp ./engine/main.cpp ./engine/font.cpp ./engine/model.cpp ./engine/button.cpp ./theme.cpp ./level_manager.cpp ./menu/menu.cpp

LOCAL_SHARED_LIBRARIES := SDL2 Freetype2

LOCAL_LDLIBS := -lGLESv1_CM -lGLESv2 -llog 

include $(BUILD_SHARED_LIBRARY)

Kua kite pea koe, ka whakauruhia e ahau te whare pukapuka Freetype2. I kitea e ahau he mea kua rite i runga i te github mo te phi, engari kaore i mahi, me whakarereke e au tetahi mea. Ka hanga ano e matou he raarangi whaiaronga / src / matua / rawa. Ka tuuhia a maatau rauemi ki roto (momotuhi, sprites, tauira 3D).

Inaianei me whirihora a Freetype2 mo te Android. Tikiake mai i taku github hono, ka kape i te whaiaronga Freetype2 ki te raarangi taupānga/jni/. Kua reri katoa. Whakahaerehia te whakahau ./gradlew installDebug ki com.xverizex.test. Kia taea ai te taapiri i tenei keemu ki te phi, me whakahohe te patuiro ki te phi. Ki te mahi i tenei, me haere koe ki nga tautuhinga, haere ki te "Pūnaha", haere ki te "Mo te papa" ka paato i te waahanga "Hanga tau" mo te ono nga wa. Na ka hoki ki muri ka puta te whiringa mo nga kaihanga. Haere ki roto ka huri, ka huri ano i te "USB Debugging" kōwhiringa. Inaianei me tiki e koe he taviri mo te papa. Ki te mahi i tenei, whakauruhia te kaupapa adb. Ka whakarewahia e matou te anga adb i roto i te papatohu, ka puta mai he matua ki te papa me whakaae. Koia, inaianei ka taea te tango keemu ki to papa.
