This commit adds support for the map2 protocol command (10 layer map).
This changes how the data is stored and sent to the client. This also
implements the idea of client handling map animations, so adds some object
flags so that the server knows if it should let the client handle animations
or not. Support for the original map protocol command is removed.
---
aclocal.m4: rebuilt
configure.ac: Add checks for zlib.h, libz - not used right now, but will
probably be used in the future, so no reason to remove it.
common/loader.l: Add client_anim_sync, client_anim_random FLAGS.
common/map.c: Add add_face_layer() to set face for a layer. Redo/simplify
update_position to store faces away based on layering criteria.
common/time.c: Replace long pticks with a uint32, since size of a long will
vary, and we now send pticks to the client as a 32 bit value.
crossedit/CrEdit.c: Update the draw logic based on the fact there are more
layers now.
crossedit/Edit.c: Comment out some code that probably should be fixed.
Replace calls of SET_MAP_FACE with SET_MAP_FACE_OBJ
doc/Developers/protocol: Updated with map2, tick protocol additions.
Reorganize the parameters in the setup protocol command so they are now
listed in alphabetical order.
include/autoconf.h.in: Add HAVE_ZLIB_H define.
include/define.h: Update for the FLAG_CLIENT_ANIM values.
include/face.h: Remove MapLook structure - no longer used.
include/global.h: change extern type for pticks from long to uint32
include/map.h: Change MAP_LAYERS to 10. Add definitions for what each
map layer is. Remove GET/SET_MAP_FACE macro - no longer used,
GET/SET_MAP_FACE_OBJ replaces it. Add GET_MAP_FACE_OBJS which
returns pointer to all the object info for the space. Remove
faces from MapSpace structure.
include/newclient.h: Update with new defines used for map2 protocol
command.
include/newserver.h: Change type of faces in map_cell_struct to be
uint16 to be consistent. Change 'count' to 'darkness' to more
accurately describe what it represents. Add MAP2_COORD_OFFSET
define. Add Map2Cmd to MapMode enum. Add map_scroll_x/y
to socket structure so we send those as part of map2 command.
Add tick field to socket structure to know if we should send
tick data to the client.
server/login.c: Remove extern long pticks declaration - declared
in global.h - don't need to declare it again locally.
socket/info.c: Rewrite magic map code to use GET_MAP_FACE_OBJ
instead of GET_MAP_FACE macros.
socket/init.c: Initialize new fields in socket structure to 0.
socket/loop.c: If client wants tick data sent, send one each tick.
socket/request.c: Add setup responses for tick, map2 requests. Remove some
extra code in Map1a setup. Send error message to client if not using
at least Map1 protocol level. Modify map_newmap_cmd() to clear
scroll information when using Map2. Remove original (map0) protocol
logic. Update map_clearcell() to clear all 10 layers. Replace
MAX_LAYERS with MAP_LAYERS. Add add_head() to remove some of the
complication from update_space(). Add code in draw_client_map1()
to find which 3 layers to send to the client from the 10 we now have.
Add map2_add_ob(), map2_delete_layer(), check_space_for_heads(),
draw_client_map2() to handle map2 protocol. Add send_tick() -
sends tick to client, but also forces flush of data to reduce lag.
utils/config.guess.utils/config.sub,utils/ltmain.sh: rebuilt

This change mostly deals with improving behaviour of pet monstes.
Most of the code is from K. Reinert - however, I did some code cleanup/
fixes related to pet monsters, so it is difficult to note where
each piece of code came from. One thing this does fix is handling of
multipart pets - these now work properly.
common/map.c: Update comment for get_rangevector() - no code change.
common/object.c: Add get_search_arr() which is used in pet monster code.
This returns a semi random scrambling of the freearr array.
doc/Developers/protocol: Update documentation about map1a protocol command.
include/libproto.h, include/sproto.h: rebuilt.
server/attack.c: Have drain attacks return 1 damage so that it is clear
that you are actually hitting your opponent. Otherwise, you would
get messages that 'you missed xyz', even though you are draining it.
This extra point of damage shouldn't change balance in any significant
way.
server/monster.c: Update hnadling of enemies for pet monsters. It should
more intelligently choose the monsters and not switch/clear the
enemy field for no reason anymore. Change find_nearest_living_creature to
use the get_search_arr() to more randomly choose direction of target -
before, there was a proclivity to always look in the north direction.
Modify can_hit() to look for closes part of enemy - otherwise, monsters
may not attack opponents even if they were right next to them because
they couldn't get to the enemies head. Remove move_object from
this function - merged with move_ob in move.c
server/move.c: Fix move_ob to use 'cleaner' code of move_object, but
also have specific features that move_ob had (player handling).
Before move_ob didn't handle multipart objects correctly, and the
two functions were largely the same. Now move_object() just calls
move_ob - the only difference in the functions is that move_ob()
takes 3 parameters instead of 2 of move_object() (added
parameter is originator). I think this should now mean multipart
player objects may now work.
server/pets.c: get_pet_enemy enhanced to be much smarter about
selecting/finding things for the pet to attack.
server/player.c: Remove commented out line of init_beforeplay

Revision 1.5mwedel 2002/05/30 23:18:33 +16 -10
Main change is the addition of name_pl and client_type to object
structure. The name_pl contains the proper plural name instance - fixes
problem of '2 tooths'. client_type is sent to the client so that client
doesn't need to figure out sorting on its own. Client_type is an object
attribute, so can be modified in maps to hide the real type.
--
common/arch.c: item_matched_string() modified to use the name_pl field
when trying to match names, and not to try to make the name plural
itself.
common/item.c: query_short_name(),query_base_name() modified to
use name_pl instead of trying to make the name plural.
common/loader.c, common/loader.l: Add code to load and save the name_pl
value and client_type. Add logic when object is finished loading
to set name_pl value to same as name or arch name if no name_pl
is specified - this supports old maps/characters in which the objects
dont have a name_pl field yet. Disable logic for need_an and need_ie
flags since they are no longer needed. Fix bug that caused
elevation not to get saved.
common/object.c: Add client_type check for CAN_MERGE function. Add
appropriate logice in functions to handle setting, clearing, and
copying of name_pl values. Remove unused anim_... fields
initialization.
doc/Developers/objects: Add information about the name_pl field and
client_type.
doc/Developers/protocol: Remove item protocol command info - it has
been obsoleted. Add information about item2 protocol command.
include/define.h: Remote ST1_* values - they were not being used.
comment out FLAG_AN and FLAG_NEED_IE values.
include/newserver.h: Add itemcmd to socket structure - this is the
version of the item protocol command that will be sent to the client.
include/object.h: Add name_pl and client_type field to object structure.
Remove unused anim_* values.
lib/archetypes: rebuilt with new archetypes that contain client_type
and name_pl information.
lib/bmaps, lib/bmaps.paths, lib/crossfire.1, lib/crossfire.0, lib/faces:
rebuilt.
server/monster.c: Remove anim_ references that were not being used.
socket/init.c: Initialize itemcmd version in the socket to 1.
socket/item.c: Remove special handling for clients of old versions - all
clients now have to be at least sc_version 1024 (which has been around for
a long time). This simplifies a lot of the object code that deals with
sending or not sending plural names to the client - now always send them.
Change code that sends item to client to use the item revision (currently
1 or 2) that the client wants. If version 2, send along client_type
information.
socket/request.c: Handle 'itemcmd' parameter in setup command. Make
sure it is in proper range. If client is very old (sc_version < 1024)
tell them so.

The bulk of this commit is to modify the server to only send the lower
rightmost part of multipart archetypes that use the same head. This allows
support of big images in the client.

common/arch.c: Modify first_arch_pass to figure out the tail_x/y values for
multipart archs. Rename the prev variable to head, as that it really what
it is. Remove quick_pos info.
common/object.c: remove quick_pos info from object.
doc/Developers/images: Add notes about using merged images.
doc/Developers/protocol: Add information about the map1a command, which
is used to for big image support. Remove map2 documentation.
include/map.h: Add MAP_LAYERS define instead of using hardcoded value of 3.
include/newserver.h: Change the MapCell to use MAP_LAYERS - saves
considerable memory. Add defines for MAX_CLIENT_ map sizes.
Remove map1cmd, map2cmd elements from socket structure - instead use enumeration
of mapmode - only one map type will be used at any time by the client, so
no reason to have individual elements - it also makes it easier to add new
mapmode commands.
include/object.h: remove quick_pos, update_tag from object structure.
Add tail_x, tail_y values to archetype structure.
include/player.h: Remove some now unused values from the player structure
(drawn, floor, floor2, darkmask). These have been superseded by the
map cells in the socket structure for quite a while.
include/sockproto.h: rebuilt
server/player.c: Remove code that initialized the drawn values in the player
structure since they no longer exist.
socket/init.c: Replace map1cmd, map2cmd elements in socket structure with
mapmode element. Modify init_ericserver so that it properly passes an
int when setting the SO_REUSERADDR field.
socket/request.c: Modify code in SetUp function to use the new mapmode
enumeration in the socket structure. Add support for map1acmd setup
option. Throughout map code, replace MAXMAPCELLFACES with MAP_LAYERS.
modify map_clearcell to take options for values to clear the cell to.
Add have_head, check_head, and update_space commands - used with the
map1 command to store and find head information.
draw_client_map1 modified to support map1a extensions, as well as added
logic for checking for heads in blocked and out of viewable map spaces.
Some of the code is simplified by using the update_space function, since
the logic for processing each layer was otherwise the same. remove
draw_client_map2 function. esrv_map_scroll has same logic - some
variables and code formatting changes.

Update to improve image caching and faceset support in the client.
The main change is adding the 'requestinfo image_info' and
'requestinfo image_sums' commands.
common/image.c: Checksum the bmaps file when we load it - we send this as
part of the image_info data.
doc/Developers/protocol: Document the requestinfo data.
include/global.h: Add extern for bmaps_checksum, and the define for
ROTATE_RIGHT which is used for checksumming.
include/newserver.h: Update SC version to 1027 so that clients can
know if they can issue requestinfo commands.
include/sockproto.h: rebuilt
lib/adm/collect_images.pl: Add support for it to make a crossfire-images
distribution that the client can use to bootstrap its image set.
socket/image.c: Change SendFaceCmd to take a NewSocket parameter instead
of a player parameter - in this way, it can be used before the
AddMe command - this allows the client to download images before
issuing that command. Add send_image_info and send_image_sums
function which send the requestinfo data to the client.
socket/loop.c: Move the askface command from the player commands to the
newsocket commands. Add RequestInfo functino that determines the
type of request and calls the specific function to deal with it.
