        }
        //LOGIC//

        //point playerRect at mouse pos
        std::cout << mouseX << "\n";
        std::cout << mouseX << "\n";

        dx = mouseX - playerX;
        dy = mouseY - playerY;
        trigresult = atan2(dy,dx) * 180/PI;
        playerRect.setRotation(trigresult + 90);
       
        //RENDERING//

        window.clear();

        window.draw(playerRect);

        window.display();
    }
}

I hope this is enough code for you to help(also note that the first std::cout for mouseX didn't actually output anything to the console, but when I inserted it twice it worked ( )

General / [WIN7] Odd problem with std::cout

« on: January 26, 2013, 12:47:29 am »

I'm in an odd situation right now:

        //point playerRect at mouse pos
        std::cout << mouseX << "\n";

        dx = mouseX - playerX;
        dy = mouseY - playerY;
        trigresult = atan2(dy,dx) * 180/PI;
        playerRect.setRotation(trigresult + 90);

For some reason, whenever I comment out the "std::cout << mouseX << "\n"", the trigresult only outputs 90 or -90 degrees with cout(so playerRect is either pointing straight up or straight down). And whenever it is there/isn't commented out, it works correctly and trigresult prints out correct results. Anyone know why this is?

Thanks in advance.
