/*************************************************************************
POSITION VARIABLES:
POSX is your x - position ranging from 0 to 65535
POSY is your y - position ranging from 0 to 65535
(the length of a side of the grid in EDITBORD would be 1024)
POSZ is your z - position (height) ranging from 0 to 65535, 0 highest.
ANG is your angle ranging from 0 to 2047. Instead of 360 degrees, or
2 * PI radians, I use 2048 different angles, so 90 degrees would
be 512 in my system.
SPRITE VARIABLES:
EXTERN short headspritesect[MAXSECTORS+1], headspritestat[MAXSTATUS+1];
EXTERN short prevspritesect[MAXSPRITES], prevspritestat[MAXSPRITES];
EXTERN short nextspritesect[MAXSPRITES], nextspritestat[MAXSPRITES];
Example: if the linked lists look like the following:
ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿
³ Sector lists: Status lists: ³
ÃÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ´
³ Sector0: 4, 5, 8 Status0: 2, 0, 8 ³
³ Sector1: 16, 2, 0, 7 Status1: 4, 5, 16, 7, 3, 9 ³
³ Sector2: 3, 9 ³
ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ
Notice that each number listed above is shown exactly once on both the
left and right side. This is because any sprite that exists must
be in some sector, and must have some kind of status that you define.
Coding example #1:
To go through all the sprites in sector 1, the code can look like this:
sectnum = 1;
i = headspritesect[sectnum];
while (i != -1)
{
nexti = nextspritesect[i];
//your code goes here
//ex: printf("Sprite %d is in sector %d\n",i,sectnum);
i = nexti;
}
Coding example #2:
To go through all sprites with status = 1, the code can look like this:
statnum = 1; //status 1
i = headspritestat[statnum];
while (i != -1)
{
nexti = nextspritestat[i];
//your code goes here
//ex: printf("Sprite %d has a status of 1 (active)\n",i,statnum);
i = nexti;
}
insertsprite(short sectnum, short statnum);
deletesprite(short spritenum);
changespritesect(short spritenum, short newsectnum);
changespritestat(short spritenum, short newstatnum);
TILE VARIABLES:
NUMTILES - the number of tiles found TILES.DAT.
TILESIZX[MAXTILES] - simply the x-dimension of the tile number.
TILESIZY[MAXTILES] - simply the y-dimension of the tile number.
WALOFF[MAXTILES] - the actual 32-bit offset pointing to the top-left
corner of the tile.
PICANM[MAXTILES] - flags for animating the tile.
TIMING VARIABLES:
TOTALCLOCK - When the engine is initialized, TOTALCLOCK is set to zero.
From then on, it is incremented 120 times a second by 1. That
means that the number of seconds elapsed is totalclock / 120.
NUMFRAMES - The number of times the draw3dscreen function was called
since the engine was initialized. This helps to determine frame
rate. (Frame rate = numframes * 120 / totalclock.)
OTHER VARIABLES:
STARTUMOST[320] is an array of the highest y-coordinates on each column
that my engine is allowed to write to. You need to set it only
once.
STARTDMOST[320] is an array of the lowest y-coordinates on each column
that my engine is allowed to write to. You need to set it only
once.
SINTABLE[2048] is a sin table with 2048 angles rather than the
normal 360 angles for higher precision. Also since SINTABLE is in
all integers, the range is multiplied by 16383, so instead of the
normal -1<sin(x)<1, the range of sintable is -16383<sintable[]<16383
If you use this sintable, you can possibly speed up your code as
well as save space in memory. If you plan to use sintable, 2
identities you may want to keep in mind are:
sintable[ang&2047] = sin(ang * (3.141592/1024)) * 16383
sintable[(ang+512)&2047] = cos(ang * (3.141592/1024)) * 16383
NUMSECTORS - the total number of existing sectors. Modified every time
you call the loadboard function.

/*
* This module keeps track of a standard linear cacheing system.
* To use this module, here's all you need to do:
*
* Step 1: Allocate a nice BIG buffer, like from 1MB-4MB and
* Call initcache(int32_t cachestart, int32_t cachesize) where
*
* cachestart = (int32_t )(pointer to start of BIG buffer)
* cachesize = length of BIG buffer
*
* Step 2: Call allocache(int32_t *bufptr, int32_t bufsiz, uint8_t *lockptr)
* whenever you need to allocate a buffer, where:
*
* *bufptr = pointer to 4-byte pointer to buffer
* Confused? Using this method, cache2d can remove
* previously allocated things from the cache safely by
* setting the 4-byte pointer to 0.
* bufsiz = number of bytes to allocate
* *lockptr = pointer to locking uint8_t which tells whether
* the region can be removed or not. If *lockptr = 0 then
* the region is not locked else its locked.
*
* Step 3: If you need to remove everything from the cache, or every
* unlocked item from the cache, you can call uninitcache();
* Call uninitcache(0) to remove all unlocked items, or
* Call uninitcache(1) to remove everything.
* After calling uninitcache, it is still ok to call allocache
* without first calling initcache.

ENet 1.3.13 (April 30, 2015):
* miscellaneous bug fixes
* added premake and cmake support
* miscellaneous documentation cleanups
ENet 1.3.12 (April 24, 2014):
* added maximumPacketSize and maximumWaitingData fields to ENetHost to limit the amount of
data waiting to be delivered on a peer (beware that the default maximumPacketSize is
32MB and should be set higher if desired as should maximumWaitingData)
ENet 1.3.11 (December 26, 2013):
* allow an ENetHost to connect to itself
* fixed possible bug with disconnect notifications during connect attempts
* fixed some preprocessor definition bugs
ENet 1.3.10 (October 23, 2013);
* doubled maximum reliable window size
* fixed RCVTIMEO/SNDTIMEO socket options and also added NODELAY
ENet 1.3.9 (August 19, 2013):
* added duplicatePeers option to ENetHost which can limit the number of peers from duplicate IPs
* added enet_socket_get_option() and ENET_SOCKOPT_ERROR
* added enet_host_random_seed() platform stub
ENet 1.3.8 (June 2, 2013):
* added enet_linked_version() for checking the linked version
* added enet_socket_get_address() for querying the local address of a socket
* silenced some debugging prints unless ENET_DEBUG is defined during compilation
* handle EINTR in enet_socket_wait() so that enet_host_service() doesn't propagate errors from signals
* optimized enet_host_bandwidth_throttle() to be less expensive for large numbers of peers
ENet 1.3.7 (March 6, 2013):
* added ENET_PACKET_FLAG_SENT to indicate that a packet is being freed because it has been sent
* added userData field to ENetPacket
* changed how random seed is generated on Windows to avoid import warnings
* fixed case where disconnects could be generated with no preceding connect event
ENet 1.3.6 (December 11, 2012):
* added support for intercept callback in ENetHost that can be used to process raw packets before ENet
* added enet_socket_shutdown() for issuing shutdown on a socket
* fixed enet_socket_connect() to not error on non-blocking connects
* fixed bug in MTU negotiation during connections
ENet 1.3.5 (July 31, 2012):
* fixed bug in unreliable packet fragment queuing
ENet 1.3.4 (May 29, 2012):
* added enet_peer_ping_interval() for configuring per-peer ping intervals
* added enet_peer_timeout() for configuring per-peer timeouts
* added protocol packet size limits
ENet 1.3.3 (June 28, 2011):
* fixed bug with simultaneous disconnects not dispatching events
ENet 1.3.2 (May 31, 2011):
* added support for unreliable packet fragmenting via the packet flag
ENET_PACKET_FLAG_UNRELIABLE_FRAGMENT
* fixed regression in unreliable packet queuing
* added check against received port to limit some forms of IP-spoofing
ENet 1.3.1 (February 10, 2011):
* fixed bug in tracking of reliable data in transit
* reliable data window size now scales with the throttle
* fixed bug in fragment length calculation when checksums are used
ENet 1.3.0 (June 5, 2010):
* enet_host_create() now requires the channel limit to be specified as
a parameter
* enet_host_connect() now accepts a data parameter which is supplied
to the receiving receiving host in the event data field for a connect event
* added an adaptive order-2 PPM range coder as a built-in compressor option
which can be set with enet_host_compress_with_range_coder()
* added support for packet compression configurable with a callback
* improved session number handling to not rely on the packet checksum
field, saving 4 bytes per packet unless the checksum option is used
* removed the dependence on the rand callback for session number handling
Caveats: This version is not protocol compatible with the 1.2 series or
earlier. The enet_host_connect and enet_host_create API functions require
supplying additional parameters.
ENet 1.2.5 (June 28, 2011):
* fixed bug with simultaneous disconnects not dispatching events
ENet 1.2.4 (May 31, 2011):
* fixed regression in unreliable packet queuing
* added check against received port to limit some forms of IP-spoofing
ENet 1.2.3 (February 10, 2011):
* fixed bug in tracking reliable data in transit
ENet 1.2.2 (June 5, 2010):
* checksum functionality is now enabled by setting a checksum callback
inside ENetHost instead of being a configure script option
* added totalSentData, totalSentPackets, totalReceivedData, and
totalReceivedPackets counters inside ENetHost for getting usage
statistics
* added enet_host_channel_limit() for limiting the maximum number of
channels allowed by connected peers
* now uses dispatch queues for event dispatch rather than potentially
unscalable array walking
* added no_memory callback that is called when a malloc attempt fails,
such that if no_memory returns rather than aborts (the default behavior),
then the error is propagated to the return value of the API calls
* now uses packed attribute for protocol structures on platforms with
strange alignment rules
* improved autoconf build system contributed by Nathan Brink allowing
for easier building as a shared library
Caveats: If you were using the compile-time option that enabled checksums,
make sure to set the checksum callback inside ENetHost to enet_crc32 to
regain the old behavior. The ENetCallbacks structure has added new fields,
so make sure to clear the structure to zero before use if
using enet_initialize_with_callbacks().
ENet 1.2.1 (November 12, 2009):
* fixed bug that could cause disconnect events to be dropped
* added thin wrapper around select() for portable usage
* added ENET_SOCKOPT_REUSEADDR socket option
* factored enet_socket_bind()/enet_socket_listen() out of enet_socket_create()
* added contributed Code::Blocks build file
ENet 1.2 (February 12, 2008):
* fixed bug in VERIFY_CONNECT acknowledgement that could cause connect
attempts to occasionally timeout
* fixed acknowledgements to check both the outgoing and sent queues
when removing acknowledged packets
* fixed accidental bit rot in the MSVC project file
* revised sequence number overflow handling to address some possible
disconnect bugs
* added enet_host_check_events() for getting only local queued events
* factored out socket option setting into enet_socket_set_option() so
that socket options are now set separately from enet_socket_create()
Caveats: While this release is superficially protocol compatible with 1.1,
differences in the sequence number overflow handling can potentially cause
random disconnects.
ENet 1.1 (June 6, 2007):
* optional CRC32 just in case someone needs a stronger checksum than UDP
provides (--enable-crc32 configure option)
* the size of packet headers are half the size they used to be (so less
overhead when sending small packets)
* enet_peer_disconnect_later() that waits till all queued outgoing
packets get sent before issuing an actual disconnect
* freeCallback field in individual packets for notification of when a
packet is about to be freed
* ENET_PACKET_FLAG_NO_ALLOCATE for supplying pre-allocated data to a
packet (can be used in concert with freeCallback to support some custom
allocation schemes that the normal memory allocation callbacks would
normally not allow)
* enet_address_get_host_ip() for printing address numbers
* promoted the enet_socket_*() functions to be part of the API now
* a few stability/crash fixes
