Opening a hi-res screen

Nightfox · 14 July 2020, 13:11

Hi all. I am trying to open a hi res screen (640 x 256) but it's only opening a low res one. Is there anything I'm missing?

Code:

 struct NewScreen NewScreen;
NewScreen.LeftEdge = 0;
NewScreen.TopEdge = 0;
NewScreen.Width = 640;
NewScreen.Height = 256;
NewScreen.Depth = 4;
NewScreen.DetailPen = 0;
NewScreen.BlockPen = 1;
NewScreen.ViewModes = NULL;
NewScreen.Type = CUSTOMSCREEN;
NewScreen.Font = &Font;
NewScreen.DefaultTitle = "DF0";
NewScreen.Gadgets = NULL;
NewScreen.CustomBitMap = NULL;

if ((Screen = (struct Screen *)OpenScreen(&NewScreen)) == NULL)
return 1;

ViewModes hasn't been set. It should be HIRES (from graphics/view.h).

Merci! My Intuition journey only began yesterday. Until now I've only been doing direct hardware programming

If you're writing for 3.x and up, best is to use screenmode selector code instead of the old non-monitor-aware fixed screenmodes.
