Blinking Window in SFML

[Sohil Shrestha7]

using SFML in visual studio 2012 ....
this code gives blinking window.
can anyone tell me how to fix it .. or fix it ..

#include<iostream>

You have not initialized q that you use to calculate the position of charact.

[Sohil Shrestha7]

i was trying to solve it..
check the second code plz....
Need urgent help on this...
have to submit project by next week...

[Sohil Shrestha7]

Can anybody help..
Plzasap

[Fransje]

You need to pause the program before it exits. Add #include <SFML\System.hpp> (I think) and put sf::sleep( sf::seconds( 3.0f ) ); before the return 0 statement in main(). This will make the window stay open for 3 seconds before closing.

Looked at the wrong code :/

[Peter87]

But he's using a loop loop ...

What exactly do you mean by blinking window. Can you describe it for me because I don't have SFML installed so I can't test it myself.

[Sohil Shrestha7]

I think the main() function and gamef() function are constantly being called ...
If i press C , it keeps blinking...
In my orginal project, the background has 2 pictures and they keeping switching
Continuously...
But the program does take input and display what needs to be..
The only problem is it keeps blinking(switching i guess)

[Sohil Shrestha7]

not working...
would appreciate any help...
