Setting full screen
#1
In the listed graphic setup code for the early projects, the init_ogl function is a basic system which works fine for windowed EGL display, but it should also be possible to set full screen mode by sending either 1920x1080 or the returns value from
Code:
    uint width, height;
    graphics_get_display_size(0, &width, &height);
    init_ogl(p_state, width, height);

However due to a missing set up in the init_ogl function, on page 47, the early projects can't go full screen, but you can correct this by adding two lines as noted here

PHP Code:
    state->width width;
    
state->height height;
    
    
dest_rect.0;
    
dest_rect.0;
    
dest_rect.width state->width// it needs to know our window size
    
dest_rect.height state->height;
    
    
src_rect.0;
    
src_rect.0;
//ADD these two lines if you are using a full screen mode    
    
src_rect.width width << 16;
    
src_rect.height height << 16

The downloaded files should all have this fix but I will check to make sure.
