From 1452d43c6d7c89219cda91362da53ac8e4acb887 Mon Sep 17 00:00:00 2001 From: Christian Heller Date: Fri, 4 Jul 2014 23:18:05 +0200 Subject: [PATCH] Load last world state from save file, not from re-stepping record file. Re-wrote large chunks of code dealing with server message parsing and file parsing in general. Introduced "god commands" (manipulating the game state beyond player actor control) that direct the re-generation of the game state when loading the save file. Introduced a module "hardcoded_strings" to store strings re-used and expected among various modules. --- README | 22 +- TODO | 18 +- src/client/command_db.c | 15 +- src/client/interface_conf.c | 22 +- src/common/parse_file.c | 147 +++++++++----- src/common/parse_file.h | 36 ++-- src/server/ai.c | 11 +- src/server/cleanup.c | 7 +- src/server/configfile.c | 46 +++-- src/server/configfile.h | 4 +- src/server/hardcoded_strings.c | 39 ++++ src/server/hardcoded_strings.h | 47 +++++ src/server/init.c | 110 ++++++---- src/server/init.h | 20 +- src/server/io.c | 116 +++++++++-- src/server/io.h | 27 ++- src/server/main.c | 8 +- src/server/map.c | 7 +- src/server/map.h | 14 +- src/server/run.c | 360 ++++++++++++++++++++++++++------- src/server/run.h | 8 +- src/server/things.c | 75 ++++--- src/server/things.h | 13 +- src/server/world.h | 10 +- 24 files changed, 840 insertions(+), 342 deletions(-) create mode 100644 src/server/hardcoded_strings.c create mode 100644 src/server/hardcoded_strings.h diff --git a/README b/README index 8b79cf2..9775dd8 100644 --- a/README +++ b/README @@ -15,10 +15,9 @@ Enemies' AI is very dumb so far: Each turn, they try to move towards their shortest-path-wise nearest enemy visible to them.
