2019年春第四次课程设计实验报告

2019年春第四次课程设计实验报告
实验项目名称:
双人游戏
功能描述:
由玩家操控飞机进行游戏并累计得分。
项目结构模块介绍:
1.全局变量
int ball_x,ball_y; // 小球的坐标
int ball_vx,ball_vy; // 小球的速度
int radius; // 小球的半径
int bar1_left,bar1_right,bar1_top,bar1_bottom; // 挡板1的上下左右位置坐标
int bar2_left,bar2_right,bar2_top,bar2_bottom; // 挡板2的上下左右位置坐标
int bar_height,bar_width; // 挡板的高度、宽度

2.数据初始化
void startup() // 数据初始化
{
ball_x = Width/2;
ball_y = High/2;
ball_vx = 1;
ball_vy = 1;
radius = 20;
bar_width = Width/30;
bar_height = High/2;
bar1_left = Width * 1/20;
bar1_top = High/4;
bar1_right = bar1_left + bar_width;
bar1_bottom = bar1_top + bar_height;
bar2_left = Width * 18.5/20;
bar2_top = High/4;
bar2_right = bar2_left + bar_width;
bar2_bottom = bar2_top + bar_height;
initgraph(Width,High);
BeginBatchDraw();
}
3.消除画面
void clean() // 消除画面
{
setcolor(BLACK);
setfillcolor(BLACK);
fillcircle(ball_x, ball_y, radius);
fillcircle(ball_x, ball_y, radius);
bar(bar1_left,bar1_top,bar1_right,bar1_bottom);
bar(bar2_left,bar2_top,bar2_right,bar2_bottom);
}

4.显示画面
void show() // 显示画面
{
setcolor(GREEN);
setfillcolor(GREEN);
fillcircle(ball_x, ball_y, radius); // 绘制绿圆
setcolor(YELLOW);
setfillcolor(YELLOW);
bar(bar1_left,bar1_top,bar1_right,bar1_bottom); // 绘制黄色挡板
bar(bar2_left,bar2_top,bar2_right,bar2_bottom);
FlushBatchDraw();
// 延时
Sleep(3);
}
5.与用户输入无关的更新
void updateWithoutInput() // 与用户输入无关的更新
{
// 挡板和小圆碰撞,小圆反弹
if (ball_x+radius>=bar2_left && ball_y+radius>=bar2_top && ball_y+radius<=bar2_bottom)
ball_vx = -ball_vx;
else if (ball_x-radius<=bar1_right && ball_y+radius>=bar1_top && ball_y+radius<=bar1_bottom)
ball_vx = -ball_vx;
// 更新小圆坐标
ball_x = ball_x + ball_vx;
ball_y = ball_y + ball_vy;
if ((ball_x<=radius)||(ball_x>=Width-radius))
ball_vx = -ball_vx;
if ((ball_y<=radius)||(ball_y>=High-radius))
ball_vy = -ball_vy;
}

6.与用户输入有关的更新
void updateWithInput() // 与用户输入有关的更新
{
int step = 1;
if (GetAsyncKeyState(0x57) & 0x8000 ) // w
bar1_top-=step;
if ((GetAsyncKeyState(0x53) & 0x8000)) //s
bar1_top+=step;
if ((GetAsyncKeyState(VK_UP) & 0x8000)) // 上方向键
bar2_top-=step;
if ((GetAsyncKeyState(VK_DOWN) & 0x8000)) // 下方向键
bar2_top+=step;
bar1_bottom = bar1_top + bar_height;
bar2_bottom = bar2_top + bar_height;
}
void gameover()
{
EndBatchDraw();
closegraph();
}

实验总结:
这周电脑出现了一些小故障导致git和easyx都卸载了,所以暂无截图。
