I have a problem and seeking your help on this. In some games, the GUI of the game are in fixed size (example 100x100 px) and when the screen resolution changed (say example from 1024x780 to 1200x1024) the GUI will always remain the same size (100x100px) when although it would look smaller in the higher resolution. However for my case, when we change the screen resolution, the GUI scaled along with it. I seeking your advice on how we can make permanent size of the GUI without the scaling issue.

Thanks in advance ppl

D.scale(600 / (float)D.y()); put that in your main update loop and the gui will always be same scale

Thanks TBJokers. I will try this and let you know if this work

EDIT: Its working perfectly well now. This is what we wanted Thanks man
