c++使用easyx做出像素鸟，简单上手小游戏
老规矩，先上效果图
1首先加载一堆资源图片
// 加载图片资源
void loadRes()
{
loadimage(&BK[0], _T("res\\bg_day.png"));
loadimage(&BK[1], _T("res\\bg_night.png"));
loadimage(&bk, _T("res\\bg_day.png"));
loadimage(&OVEIMG, _T("res\\bg_day.png"));
loadimage(&BIRD[0][0], _T("res\\bird0_0.png"));
loadimage(&BIRD[0][1], _T("res\\bird0_1.png"));
loadimage(&BIRD[0][2], _T("res\\bird0_2.png"));
loadimage(&BIRD[1][0], _T("res\\bird1_0.png"));
loadimage(&BIRD[1][1], _T("res\\bird1_1.png"));
loadimage(&BIRD[1][2], _T("res\\bird1_2.png"));
loadimage(&BIRD[2][0], _T("res\\bird2_0.png"));
loadimage(&BIRD[2][1], _T("res\\bird2_1.png"));
loadimage(&BIRD[2][2], _T("res\\bird2_2.png"));
loadimage(&PIPE[0][0], _T("res\\pipe_down.png"));
loadimage(&PIPE[0][1], _T("res\\pipe_up.png"));
loadimage(&PIPE[1][0], _T("res\\pipe2_down.png"));
loadimage(&PIPE[1][1], _T("res\\pipe2_up.png"));
loadimage(&NUMBER[0][0], _T("res\\font_048.png"));
loadimage(&NUMBER[0][1], _T("res\\font_049.png"));
loadimage(&NUMBER[0][2], _T("res\\font_050.png"));
loadimage(&NUMBER[0][3], _T("res\\font_051.png"));
loadimage(&NUMBER[0][4], _T("res\\font_052.png"));
loadimage(&NUMBER[0][5], _T("res\\font_053.png"));
loadimage(&NUMBER[0][6], _T("res\\font_054.png"));
loadimage(&NUMBER[0][7], _T("res\\font_055.png"));
loadimage(&NUMBER[0][8], _T("res\\font_056.png"));
loadimage(&NUMBER[0][9], _T("res\\font_057.png"));
loadimage(&NUMBER[1][0], _T("res\\number_context_00.png"));
loadimage(&NUMBER[1][1], _T("res\\number_context_01.png"));
loadimage(&NUMBER[1][2], _T("res\\number_context_02.png"));
loadimage(&NUMBER[1][3], _T("res\\number_context_03.png"));
loadimage(&NUMBER[1][4], _T("res\\number_context_04.png"));
loadimage(&NUMBER[1][5], _T("res\\number_context_05.png"));
loadimage(&NUMBER[1][6], _T("res\\number_context_06.png"));
loadimage(&NUMBER[1][7], _T("res\\number_context_07.png"));
}
2 初始化游戏资源
void init()
{
// 加载图形资源
loadRes();
// 初始化图形界面
initgraph(288, 512);
// 初始化随机数种子
srand((unsigned int)time(NULL));
// 初始化变量
best = 0;
isDay = rand() % 2;
birdColor = rand() % 3;
// 游戏初始时间
clock_t time = clock();
// 开场动画
while (true)
{
reset();
drawAlpha(&bk, 60, 120, &TITLE);
drawAlpha(&bk, 125, 200, &BIRD[birdColor][pose]);
drawAlpha(&bk, 90, 270, &PLAY);
pose = ((clock() - time) / diff) % 3;
put();
if (GetControl())
{
break;
}
Sleep(10);
}
}
3开始游戏
// 游戏预处理
void start()
{
// 初始化数据
isDay = rand() % 2;
birdColor = rand() % 3;
pipeX[0] = 288 + 30;
pipeX[1] = 288 + 30 + 190;
pipeY[0] = rand() % 250;
pipeY[1] = rand() % 250;
pose = 0;
landX = 0;
score = 0;
y = 220;
vy = 0;
// 游戏初始时间
clock_t time = clock();
// 开场动画
clock_t t = clock();
while (true)
{
reset();
drawScore(60, score, 13, 26, 144, 0);
drawAlpha(&bk, 50, 120, &READY);
drawAlpha(&bk, (int)x, (int)y, &BIRD[birdColor][pose]);
drawAlpha(&bk, 90, 220, &TUTORIAL);
drawAlpha(&bk, (int)landX, (int)landY, &LAND);
landX -= (clock() - t) * vx / 100;
t = clock();
pose = ((clock() - time) / diff) % 3;
put();
if (landX < -44)
{
landX = -20;
}
if (GetControl())
{
break;
}
Sleep(10);
}
}
4操控像素鸟
bool GetControl()
{
bool res = false;
if (_kbhit())
{
char ch = _getch();
if (ch == ' ')
{
res = true;
}
}
MOUSEMSG msg;
while (MouseHit())
{
msg = GetMouseMsg();
if (msg.mkLButton)
{
res = true;
}
}
return res;
}
这里面操控比较简单，就是鼠标单机/按下空格键，像素鸟都会弹一下。
5鸟死亡，判断gameover的逻辑
// 判断鸟死亡
bool isDie()
{
if (y + buttom > landY)
return true;
if (x + right > pipeX[0] && x + left < pipeX[0] + 52)
{
if (y + top < pipeY[0] + 40 || y + buttom > pipeY[0] + 140)
return true;
}
if (x + right > pipeX[1] && x + left < pipeX[1] + 52)
{
if (y + top < pipeY[1] + 40 || y + buttom > pipeY[1] + 140)
return true;
}
return false;
}
