hey, Well im having a little problem, ok here it goes. Well I create a clipper using CreateClipper() and then I set it to the primary surface using SetHWnd(). Ok then I wanted to see if it worked so I made a small program that moved a box around the screen, but whenever I get to the edge of the screen it gets stuck, when I got ride of the clipper it was fine, but I would get an invalid rect when I went of the screen, thats because there is no clipper, what should I do different to get the clipper to work? Here is how I create the clipper and set it to the primary surface:
        

        lpDD->CreateClipper(0, &lpddclipper, NULL); 
	
	lpddclipper->SetHWnd(0, hwnd);

        
Should I do it a different way or someting? I need a clipper becasue im trying to create a strategy game, and if I dont have a clipper I won't be able to get my tile engine work, Well if anyone could help me I would appreciate it, Thanks James, Later Edited by - JSCFaith on 7/16/00 5:34:30 PM

This is the code I use to set up a clipper (I''m using DX 7)

    
ClipMinX = 0;
ClipMaxX = ScreenWidth - 1;
ClipMinY = 0;
ClipMaxY = ScreenHeight - 1;

// Setup a clipper for the backbuffer/window

RECT ScreenRect = {0,0,ScreenWidth,ScreenHeight};
Clipper = AttachClipper(BBuffer,1,&ScreenRect);


I don''t know if this will help or not.

You should set it to the primary surface using IDirectSurface3->SetClipper().

Also, I believe the proper order to iniitalize & attach clippers is:

1. Set coöperative level [ must be before 2 ]
2. Create Clipper [ must be after 1 and before 3 ]
3. Create primary surface [ must be after 2 ]
4. Attach clipper to surface
