A really nasty 'if' statement...

Joel Bennett · 2000-09-02T10:23:29

I am trying to create a function that takes a RECT structure as a parameter, and checks if the mouse position is in it. This function has to be as fast as possible, as it is being called in real time, (30+fps). Here is the code that I came up with: //RECT test function int RectTest (RECT test) { if(cursor_x >= test.left){ if(cursor_y >= test.top){ if(cursor_x <= test.right){ if(cursor_y <= test.bottom) { return(RECTTEST_OK); } } } } else { return(RECTTEST_BAD); } } As you may have guessed, the x position of the mouse is stored in the cursor_x variable, and the y position of the mouse likewise in the cursor_y variable. I have define the RECTTEST_OK and RECTTEST_BAD at the beginning of the program. Here are the errors I get when I try to link/compile: D:\STYDX7IN24\Source\prototype\prototype.cpp(361) : error C2059: syntax error : ''='' D:\STYDX7IN24\Source\prototype\prototype.cpp(366) : error C2059: syntax error : ''='' D:\STYDX7IN24\Source\prototype\prototype.cpp(366) : error C2143: syntax error : missing '';'' before '')'' I can''t seem to figure it out (stupid me:p). Anyone here have an answer/better solution?

I''m confused, surely you could just use the function

PtInRect(&rc, &pt);

I was just wondering why you couldn''t just use this, which takes a pointer to a rect structure and a pointer to a point structure...

Just wondering
