From 66bbf336c6af7353ef0aeed58002c46543b30635 Mon Sep 17 00:00:00 2001 From: rubidium Date: Tue, 2 Jan 2007 19:19:48 +0000 Subject: (svn r7759) -Merge: makefile rewrite. This merge features: - A proper ./configure, so everything needs to be configured only once, not for every make. - Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies. - A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC. - Proper support for OSX universal binaries. - Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files. - Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files. Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy. --- economy.c | 1738 ------------------------------------------------------------- 1 file changed, 1738 deletions(-) delete mode 100644 economy.c (limited to 'economy.c') diff --git a/economy.c b/economy.c deleted file mode 100644 index bcd3ac552..000000000 --- a/economy.c +++ /dev/null @@ -1,1738 +0,0 @@ -/* $Id$ */ - -#include "stdafx.h" -#include "openttd.h" -#include "currency.h" -#include "functions.h" -#include "strings.h" // XXX InjectDParam() -#include "table/strings.h" -#include "table/sprites.h" -#include "map.h" -#include "news.h" -#include "player.h" -#include "station.h" -#include "vehicle.h" -#include "window.h" -#include "gfx.h" -#include "command.h" -#include "saveload.h" -#include "economy.h" -#include "industry.h" -#include "town.h" -#include "network/network.h" -#include "sound.h" -#include "engine.h" -#include "network/network_data.h" -#include "variables.h" -#include "vehicle_gui.h" -#include "ai/ai.h" -#include "train.h" -#include "newgrf_engine.h" -#include "newgrf_sound.h" -#include "newgrf_callbacks.h" -#include "unmovable.h" -#include "date.h" - -// Score info -const ScoreInfo _score_info[] = { - { SCORE_VEHICLES, 120, 100 }, - { SCORE_STATIONS, 80, 100 }, - { SCORE_MIN_PROFIT, 10000, 100 }, - { SCORE_MIN_INCOME, 50000, 50 }, - { SCORE_MAX_INCOME, 100000, 100 }, - { SCORE_DELIVERED, 40000, 400 }, - { SCORE_CARGO, 8, 50 }, - { SCORE_MONEY, 10000000, 50 }, - { SCORE_LOAN, 250000, 50 }, - { SCORE_TOTAL, 0, 0 } -};
