Design Issue - Making a Font Global (C++, Marmalade) -
i have marmalade c++ project built in font doesn't scale screen size. deal issue i'm making custom font, png , .xml file, containing (0,0) vector of each character, , each character's size. i'm creating instance of png, , drawing regions of in loop write on screen.
the issue i'm having scope of class. want used throughout entire project. static debuglogger use font, ui's, or gameobjects, need characters, use font. it's pre-built system.
the logger in project static class, static functions. custom font class have singleton, understanding, must instantiated object program draw images of it. did not make static. there clear cut answer type of problem? issue static class won't create reference singleton, , i've been told singleton avoided design perspective anyway!
thanks in advance guys!
here's code reference:
