1819.0. "Help with Graphic Objects needed" by SMAUG::SPODARYK (20, 20, 20-4 hours to go...) Wed Oct 26 1988 16:37

    A few questions:
    
 1) I am looking for information on creating and manipulating BOBs.
    I have the ROM Kernal manual, so I have some information on how
    to do this, but was wondering if there is a worthwhile graphics
    book out there.
    
 2) Is there any type of utility out to "edit" and maybe produce 
    C code for these Graphic Objects?  It would seem a necessity for 
    anyone writing a game.

 3) Another thing that would be of great help, is if anyone has any 
    examples they have worked on and would be willing to share.
    PD game code possibly?  C, Assembler, etc.                 
    
    What I have in mind is animating several objects, for use in a game.
    I'd hate to "reinvent the wheel", so any help would be appreciated.  

    Thanks - Steve

	I use a PD program called ILBMDump. This program converts IFF brushes (such as DPAINT brushes) to C source code. I then compile them to object modules and link them into my game. NOTE that image data for bobs and sprites is stored in different formats. ILBMdump produces the blitter object format. BTW: In my game, I didn't use BOBs. I used the BltMaskBitMapRastPort routine and stored objects in my own structures. I think doing it myself was easier than trying to comprehend the sloppy, buggy Gels documentation (which also fails to discuss what kind of overhead is involved). There is another PD program called Brush2C, haven't tried it.
