BCCでSDL テトリスを作ろう - プログラミング雑記

Ｃ言語+SDLでテトリス！

いつ完成するか分かりませんが、テトリスを作ろうと思います。

何から手をつけてよいのかサッパリなので先ずはこちらを参考にしましょう。http://www5f.biglobe.ne.jp/~kenmo/program/tetris/tetris.html

課題形式で作成を進めたいと言う方はこちらを参考に。

では今回のソースです。取りあえずプレイフィールドだけ表示してみました。

TetrisCanvas.cpp

#include "TetrisCanvas.h"

//フィールド変数
static SDL_Surface *screen;
static Uint8 playField[H_SIZE][W_SIZE];
static BlockArr Block[BLOCK_TYPE_ALL];

bool InitializeTetris(Uint8 initType)
{
	//SDLの初期化
	if( TetrisVideoMode(initType) == false ){
		return false;
	}
	//キャプション設定(Videoモードを設定する前に先に設定する必要がある)
	SDL_WM_SetCaption(TITLE,NULL);
	//ビデオモード設定
	screen = NULL;
	screen = SDL_SetVideoMode(
		WIDTH, HEIGHT, BPP, 
		SDL_HWSURFACE | SDL_DOUBLEBUF
	);
	
	return true;
}

bool TetrisVideoMode(Uint8 type){
	switch(type){
	case VIDEO:
		if( SDL_Init(SDL_INIT_VIDEO) < 0 ){
			return false;
		}break;
	case TIMER:
		if( SDL_Init(SDL_INIT_VIDEO | SDL_INIT_TIMER) < 0 ){
			return false;
		}break;
	case JOYSTICK:
		if( SDL_Init(SDL_INIT_VIDEO | SDL_INIT_JOYSTICK) < 0 ){
			return false;
		}break;
	case ALL:
		if( SDL_Init(SDL_INIT_VIDEO | 
		SDL_INIT_JOYSTICK | 
		SDL_INIT_TIMER) < 0 ){
			return false;
		}break;
	}//end initVIdeo
	
	return true;
}

void paintOut(void){
	
	SDL_Rect dst;
	dst.w = dst.h = BLOCK_SIZE;
	
	for(int y=0; y<H_SIZE; y++){
		for(int x=0; x<W_SIZE; x++){
			if(playField[y][x]==1){
				dst.x = x*BLOCK_SIZE;
				dst.y = y*BLOCK_SIZE;
				SDL_FillRect(screen,&dst,0xffffffff);
			}
		}
	}
	
}

void init_mapTest(void){
	
	for(int y=0;y<H_SIZE;y++){
		for(int x=0;x<W_SIZE;x++){
			if(x==0||x==11|| y >= 21 ){
				playField[y][x] = WALL;
			}
			else{
				playField[y][x] = PLAY_FIELD;
			}
		}
	}
	
}

void init_map(Uint8 (*field)[]){//マップの初期化
	/*PLAYFIELD = 0
	**WALL = 1
	**BLOCK_FIXATION = 2*/
	Uint8 map[H_SIZE][W_SIZE] = {
	//	 0 1 2 3 4 5 6 7 8 9 1011

次はブロックを表示する所までやってみたいと思います。
