Hi all,
i trying learn my self C# by web tutorials and trying coding some simple game codes as exercises, like this example i tried do it but i confused where i should start..
there are two sprites, square 32x32px named "square.png" and arrow 32x32px called "arrow.png", i trying do the following:
when the mouse cursor is right of the square, the arrow position equal cursor position, i mean if mouse cursor change its position the arrow sprite moved to new cursor position ..
i started with

int xMouse = 0;
int yMouse = 0;

what should i do after that..
i hope some help
regards
