im trying to understand the selection/picking method, so i have created a stupid program displaying only a quad on the screen.
my objective is:
if (u_clicked_on_quad) { tell_me(YES);}
else { tell_me(NO)};
it seem to “half” work.
the problem is this :
-i start to click on an empty area it say NO (OK)
-the first time i click on the quad it say Yes (OK)
-now if i click on an empty area it continue to say YES (WRONG)
basically my main loop do this :
while(1)
{
draw scene;
if (mouse pressed){i_get_mouse_x&Y;
i_go_in_selection_mode;
i_redraw_thescene;
i_exit_selection_mode;
i_print_yes_or_no};
};
so i think to have forgot somenthing or i cant understand something.
thanks in advance for help.
