我還有一個新的glut和opengl,我試圖讓鼠標移動時的相機移動,但當試圖讓鼠標在屏幕上的位置我假設你想傳遞的方法,你應該只是x和y在glutPassiveMotionFunc()參數中被引用。但是當我嘗試賦予CameraMove方法的功能時出現錯誤。我知道我錯了,但我不知道如何。glutPassiveMotionFunc問題
void helloGl::CameraMove(int x, int y)
{
oldMouseX = mouseX;
oldMouseY = mouseY;
// get mouse coordinates from Windows
mouseX = x;
mouseY = y;
// these lines limit the camera's range
if (mouseY < 60)
mouseY = 60;
if (mouseY > 450)
mouseY = 450;
if ((mouseX - oldMouseX) > 0) // mouse moved to the right
angle += 3.0f;`enter code here`
else if ((mouseX - oldMouseX) < 0) // mouse moved to the left
angle -= 3.0f;
}
void helloGl::mouse(int button, int state, int x, int y)
{
switch (button)
{
// When left button is pressed and released.
case GLUT_LEFT_BUTTON:
if (state == GLUT_DOWN)
{
glutIdleFunc(NULL);
}
else if (state == GLUT_UP)
{
glutIdleFunc(NULL);
}
break;
// When right button is pressed and released.
case GLUT_RIGHT_BUTTON:
if (state == GLUT_DOWN)
{
glutIdleFunc(NULL);
//fltSpeed += 0.1;
}
else if (state == GLUT_UP)
{
glutIdleFunc(NULL);
}
break;
case WM_MOUSEMOVE:
glutPassiveMotionFunc(CameraMove);
break;
default:
break;
}
}
