Graphics / SFML Game Development, Movement

« on: June 26, 2014, 02:14:04 pm »

Hi
i wrote the code same as the book but the after the key is released the bool variables won't reset to false
and object moves without stopping
also the object moves opposite direction, when i press W set the mPlayer.move(0,-1) but it moves to down
