Recent directx 7 code tidbits
|
For a long time I was secretive and paranoid about source code and the like.
I guess I felt like everything I had has value, and its hard to just give
away the good stuff. What really seems to have changed my mind a bit is
being involved in the quake community. There is so much help among friends,
and open source, and I really think it helps everybody along. Today I'm
putting up my directx 7, input, error logging, and sound libraries. The
source code is available by request. I'll also post it here when I put in
some comments and get rid of anything embarassing laying around. Use it
freely. My only requests are make sure I get credit if its due, inform me
of any errors, send me some money if you make any using it (and a free copy
of your app or game :). If you distribute it, make sure all files are included.
Also, I take no responsibility for anything, use at your own risk.
Directx 7.0a input library
|
NEW:Joystick support added.
The is the dx7 mouse and keyboard input library I developed and am using.
Its loosely based on the samples in the dx7 sdk, modified to combine the
two input sources. I had joystick support in the dx6 version, but its out
for a bit. I'll put it back in when I or somebody else need it I suppose.
Probably only useful for those who don't want to bother with dinput, or
don't know much about it. Hopefully it will save you a little time anyway.
I also included some code tidbits on how its used.

Directx 7.0a 3d sound library
|
This is my dx7 3d sound library. I was really happy how well and fast this
turned out. I converted part of the 3d sound dxsdk sample to make a class
based sound library. Probably most useful code on the site atm.
Directx 7 3d sound library
This is my particle class. It takes a plane in x-y (maybe normal pointing
-z, I forget what I used.) and rotates it so its always pointing at the
camera. I use it for particles, but its good for anything that always needs
to point at the camera. I draw a gradient sphere with alpha blending in
blend one mode, z-writes off (i don't care about how they are depth sorted),
and fog off. Fog off is a hack, for some reason it can get really ugly putting
blended polys in fog.

Directx 7.0a DirectPlay Library

I still haven't figured this out. If anybody would like to contribute, feel
free...please :).
Tastes filling. Less great. This is nothing, just a class that opens a file
when it is constructed, writes whatever you tell it to, and closes when
its destructed. I will be adding more error logging functionality sometime.

2D Alpha Blending library
|
This is the probably the technically culmination of my coding 'career'.
This is a 2d blitting library for directx which does alpha blending, shadows,
team colors, and all sorts of other special effects. I did most of it using
assembly to manipulate locked directx surfaces. Good stuff, if not especially
useful. I got the idea from some place selling a similar library for something
big...10k a pop comes to mind. If anybody wants the library or source, I
think I have a working one. Its a no brainer, and plugs in just about where
bltfast would, but performance wise you are probably best off using d3d
is what everybody always tells me. In any case, if you want proof that assembly
isn't dead, drop me an email. At least look at the demo of it, I spent a
lot of time on this at one point.
Project Alpha
There is actually some nice stuff in here. Voxels will make a comeback :).
Realistically, the maze solver is a great movement and path finding algorithm.
The rest is probably more fun and nostalgic for me than anybody else.
