I'm moving this topic here, was originaly posted on the wrong board. I'm curently making a tetris game. I have one problem, it's seem that the program have trouble to acces my table and i can't find out why. Here's the name of the 2 table i'm having problem with int m_iSquare_X_Position[4]; int m_iSquare_Y_Position[4]; I can store data in it, i get no trouble, but when i try to retrieve the variables in my table, all the case of my table are 0, but i know i did set the numbers in my table. It happen when i call Get_Position with my Draw_Squares function and Draw_Squares.
