Question

我正在尝试建立一个球类游戏，只需点击红色球，就会改变颜色。大理石是绘制球的函数调用。

#include<glut.h>
volatile GLint w1=GetSystemMetrics(SM_CXSCREEN),h1=GetSystemMetrics (SM_CYSCREEN);//get screen dimensions

......
......
......

void firstrow(int flag)
{
float i;

for(i=-0.25;i<0.25;i+=0.10)
{
    count++;
    if(flag>1)
    c=medium();
    if(flag>2)
    c=difficult();
marble(i,0.4,-0.5, 0.06,0.12,0.12,c);
if(c==2)
{flag1[count]=count;}
Sleep(30);
}
}

void secondrow(int flag)
{
float i;
for(i=-0.25;i<0.25;i+=0.10)
{
    count++;
    c=2;
    if(flag>2)
    c=difficult1();
marble(i,0.1,-0.5, 0.06,0.12,0.12,c);
if(c==2)
    {flag1[count]=count;}
Sleep(30);
}
}

void thirdrow(int flag)
{
float i;
for(i=-0.25;i<0.25;i+=0.10)
{
    count++;
    if(flag>1)
    c=medium();
    if(flag>2)
    c=difficult();
marble(i,-0.2,-0.5, 0.06,0.12,0.12,c);
if(c==2)
    {flag1[count]=count;}
Sleep(30);
}
}

void fourthrow(int flag)
{
float i;
for(i=-0.25;i<0.25;i+=0.10)
{
    count++;
    c=2;
    /*if(flag>1)
    c=medium();*/
    if(flag>2)
    c=difficult1();
marble(i,-0.5,-0.5, 0.06,0.12,0.12,c);
if(c==2)
    {flag1[count]=count;}
Sleep(30);
}
}

现在打印4排球后。我正在使用鼠标的2D坐标来检测特定对象。

如果程序在不同分辨率的不同计算机上运行，则用于检测点击的鼠标坐标在绘制圆圈中会有所不同。

flag1用红色存储球号。

void mymouse(int button,int state,int x,int y){

    if(button==GLUT_LEFT_BUTTON && state==GLUT_DOWN)
        drawCircle(x,y);
}

＆＃34;如何在任何屏幕尺寸的任何系统上均匀工作？＆＃34;

在不同的屏幕上opengl不同的鼠标坐标
