 Posted: Sat Nov 15, 2008 6:13 am Post subject: [Solved] Windowed mode coordinates of screen |
 |
|
The game i play is ran in windowed mode, and it only uses OpenGL mode in windowed mode.
I have the following code for my crosshair:
| Code: | POINT mouse;
GetCursorPos(&mouse);
ScreenToClient(hWnd, &mouse);
GLfloat winX, winY;
winX = (float)mouse.x;
winY= (float)mouse.y;
glBegin(GL_LINES);
glVertex2f(winX -5, winY);
glVertex2f(winX +5, winY);
glVertex2f(winX, winY -5);
glVertex2f(winX, winY +5);
glEnd();
|
It works fine, but somehow when my window isnt exactly in the upper left corner, the crosshair will be not exactly where i want it to be.
How can i fix that? Is there some kind of Windows function that reads the upperleft coordinates of a window ?
Ill give a screenshot

Try this:
| Code: | HANDLE hWindow = FindWindow(NULL, _T("Unreal Software's Counter-Strike 2D"));
GetWindowRect(hWindow, &Window_Coordinates);
OffsetRect(&Window_Coordinates, Window_Coordinates.X, Window_Coordinates.Y);
POINT Mouse_Coordinates;
GetCursorPos(&Mouse_Coordinates);
ScreenToClient(hWindow, &Mouse_Coordinates);
GLfloat Mouse_X = (float)(Mouse_Coordinates.x += Window_Coordinates.X);
GLfloat Mouse_Y = (float)(Mouse_Coordinates.y += Window_Coordinates.Y);
glBegin(GL_LINES);
glVertex2f(Mouse_X - 5, Mouse_Y);
glVertex2f(Mouse_X + 5, Mouse_Y);
glVertex2f(Mouse_X, Mouse_Y - 5);
glVertex2f(Mouse_X, Mouse_Y + 5);
glEnd(); |

Or just remove the ScreenToClient() and see what happens....
EDIT: Oh no sorry... I didn't look at the code correctly.

Why constantly retrieve the hwnd?

| just get a handle then call the loop, no need to loop getting the handle.

Made my crosshair red
| Code: |
void sys_glEnable (GLenum cap)
{
if(crosshair)
{
HWND hWnd = FindWindow(NULL, "Unreal Software's Counter-Strike 2D");
POINT mouse;
GetCursorPos(&mouse);
ScreenToClient(hWnd, &mouse);
GLfloat winX = (float)(mouse.x);
GLfloat winY = (float)(mouse.y);
float color[4];
glGetFloatv(GL_CURRENT_COLOR, color);
glBegin(GL_LINES);
glColor3ub(255,0,0);
glVertex2f(winX -5, winY);
glVertex2f(winX +5, winY);
glVertex2f(winX, winY -5);
glVertex2f(winX, winY +5);
glEnd();
glColor4f(color[0],color[1],color[2],color[3]);
}
(*orig_glEnable) (cap);
}
|
Where should i place the HWND hWnd = FindWindow() then?
Remember i'm rewriting opengl32 functions

Above the loop, inside the constructor.

| that wouldn't matter because this function glEnable is called many times.

| Well thats the point: if you call it many times, you should make it fast. So if you remove the FindWindow, it'll be faster. And the window handle won't change, so once you have the hWnd, you don't need to get it again.
