SDL2でMAPEditerを作る 〜第5回 保存・読込〜
前回は、保存するときのファイル名を入力するための文字入力Windowを作成したので、後は入力されたファイル名でMAPデータを保存する、そしてそれを読み込む部分を実装する。
バイナリ形式保存
-> 第1回で書いた通りバイナリ形式で保存する。C言語だとバイナリ書込・読込は関数一つでできるので割と簡単に実装できた。
まず、保存部分は以下のように実装した。
int save_file(char *file_name) { FILE *fp; char file[256] = {0}; int i = 0; sprintf(FILE_NAME, "%s", file_name); while (FILE_NAME[i] != '\0') { FILE_NAME[i] = toupper((unsigned char)FILE_NAME[i]); i++; } sprintf(file, "data/%s.map", file_name); i = 0; while (file[i] != '\0') { file[i] = tolower((unsigned char)file[i]); i++; } if ((fp = fopen(file, "wb")) == NULL) { return 1; } fwrite(&COL, sizeof(int), 1, fp); fwrite(&ROW, sizeof(int), 1, fp); fwrite(&OUTER_PERIPHERY, sizeof(int), 1, fp); fwrite(map_array, sizeof(int) * COL * ROW, 1, fp); fclose(fp); return 0; }
バイナリ書込モードでファイルをオープンして、fwrite関数で行・列・マップの外側・マップデータと順に書き込んでいる。あと、特殊なことをしている言えば入力された文字列を表示では大文字になるように、ファイル名は小文字になるように、toupper tolowerを使用して変換している。これは、なんとなくで実装したのでいらないっちゃあいらない部分でもある。
この関数を、-> 前回の文字入力Windowと組み合わせて以下のように、保存機能を実装した。
int display_save_window(SDL_Event e, SDL_Renderer *renderer, TTF_Font *font) { char file_name[21] = {0}; char *status; char *endptr; make_box(renderer, 244, 296, 304, 32, 255, WHITE); make_box(renderer, 246, 298, 300, 28, 255, BLACK); display_character_string(renderer, font, "SAVE?:", 250, 300); // FONT_SIZE 22 ,11pt SDL_RenderPresent(renderer); sprintf(file_name, "%s", FILE_NAME); if (accept_character_input(e, renderer, font, file_name, 316, 525) == 0) { make_box(renderer, 244, 296, 304, 32, 255, WHITE); make_box(renderer, 246, 298, 300, 28, 255, BLACK); if(save_file(file_name) == 0) { status = "SAVED!"; } else { status = "SAVING FAILD"; } while(1) { make_box(renderer, 244, 296, 304, 32, 255, WHITE); make_box(renderer, 246, 298, 300, 28, 255, BLACK); display_character_string(renderer, font, status, 250, 300); SDL_RenderPresent(renderer); if ( SDL_PollEvent(&e) ) { if (e.type == SDL_KEYDOWN && e.key.keysym.sym == SDLK_RETURN) { break; } } } } return 0; }
入力された文字列を先ほどのsave_file関数に渡している。
あと、メモとして残しておきたい部分は
* ESCキーでの処理抜けを実装するためにメインループとは別に文字入力window用のループを持っている
* 文字数制限20文字だがfile_name配列は21で宣言していること
file_name配列が21なのはC言語のstrcat関数を文字入力windowで使用していることによる。strcat関数は連結後の文字列に終端文字を自動的に付加してしまうので20文字配列に格納したいときは終端文字分のプラス1が必要になる。
バイナリ形式読込
続いてはバイナリ読込。こちらも、関数一つでできるので割と簡単に実装できた。
int load_file(char *file_name) { FILE *fp; char file[256] = {0}; int i = 0; sprintf(file, "data/%s.map", file_name); while (file_name[i] != '\0') { file_name[i] = tolower((unsigned char)file_name[i]); i++; } if ((fp = fopen(file, "rb")) == NULL) { return 1; } sprintf(FILE_NAME, "%s", file_name); i = 0; while (FILE_NAME[i] != '\0') { FILE_NAME[i] = toupper((unsigned char)FILE_NAME[i]); i++; } fread(&COL, sizeof(int), 1, fp); fread(&ROW, sizeof(int), 1, fp); fread(&OUTER_PERIPHERY, sizeof(int), 1, fp); OUT_OF_MAP = 10; map_array = realloc(map_array, sizeof(int) * COL * ROW); i = 0; while(!feof(fp)) { fread(&map_array[i++], sizeof(int), 1, fp); } fclose(fp); return 0; }
こちらは、fread関数を利用してデータを読み込んでいる。
で、呼び出す関数が以下。
int display_load_window(SDL_Event e, SDL_Renderer *renderer, TTF_Font *font) { char file_name[21] = {0}; char *status; make_box(renderer, 244, 296, 304, 32, 255, WHITE); make_box(renderer, 246, 298, 300, 28, 255, BLACK); display_character_string(renderer, font, "LOAD?:", 250, 300); // FONT_SIZE 22 ,11pt SDL_RenderPresent(renderer); if (accept_character_input(e, renderer, font, file_name, 316, 525) == 0) { if(load_file(file_name) == 0) { status = "LOADED!"; } else { status = "LOADING FAILD"; } while(1) { make_box(renderer, 244, 296, 304, 32, 255, WHITE); make_box(renderer, 246, 298, 300, 28, 255, BLACK); display_character_string(renderer, font, status, 250, 300); SDL_RenderPresent(renderer); if ( SDL_PollEvent(&e) ) { if (e.type == SDL_KEYDOWN && e.key.keysym.sym == SDLK_RETURN) { break; } } } } return 0; }

実行結果
gifだとわかりづらいが、保存・読込ができるようになった。
終わりに
以上で、マップデータの保存・読込が実装できた。これで、マップはかなり思い通りに作成できるようになった。 後は、細かい部分の使い勝手を向上させていければと思う。
