Thread: [Dev-C++] help please

Does any one see any errors here?  It compiles fine it just doesn't WORK!:(
BOOL LeftRight;
BOOL TopBottom;

BOOL ClickButton(RECT szRectName)
{
 if ((g_x > szRectName.left) && (g_x < szRectName.right))
 LeftRight = TRUE;
 else LeftRight = FALSE;

 if ((g_y < szRectName.top) && (g_y > szRectName.bottom))
 TopBottom = TRUE; 
 else TopBottom = FALSE;

 if ((LeftRight = TRUE) && (TopBottom = TRUE))
 return TRUE;
 else return FALSE;
}

Hi, 

 Can someone PLEASE tell me a website that is HTML (no downloads) that can give me a full a-z tutorial on OPEN GL for the DEV C++ compiler...
i have tried nehe.gamedev.net but that is for visual C++ and i am far too new to translate :)

Thanks for any info....

Steve.B

go to www.gamecoding.co.uk 
they have a tutorial on OpenGL with DevC++

Regards,

Jeethu Rao

I think you want to swap the < and > in the above line.

I did that that was just a unnoticed byproduct.  The acctual problem is I
cannot get the RECT info into the function.

  if (ClickButton(exit,340,470,490,510) == TRUE)
     PostQuitMessage(0);
     else  G.currGameState = GAMESTATE_NMENU;
     break;
    }

And here is the function:
BOOL ClickButton(RECT szRectName,int l,int t,int r,int b)
{
 if ((g_x < szRectName.left) && (g_x > szRectName.right))
 LeftRight = TRUE;
 else LeftRight = FALSE;

 if ((g_y > szRectName.top) && (g_y < szRectName.bottom))
 TopBottom = TRUE;
 else TopBottom = FALSE;

 if ((LeftRight = TRUE) && (TopBottom = TRUE))
 return TRUE;
 else return FALSE;
}

Hi, 

I think the mistake is down there. Check out my correction.

If you want to compare you need to use

    if ((LeftRight == TRUE) && (TopBottom == TRUE))

Otherwise you're just doing an assignment.

The prob appears to be in your if statement. Using a single equals =
character in an if statement tends to assign a vlale rather than do the =
comparison sort. Use two equal signs for the comparison to work.
