From 92b45b2a189b703fc7cfc8ddbc09a7ad563a13bc Mon Sep 17 00:00:00 2001 From: Loïc Blot Date: Fri, 27 Jan 2017 07:41:10 +0100 Subject: [CSM] implement client side mod loading (#5123) * client side mods are located in clientmods/ * move builtin/preview.lua to clientmods/preview/init.lua as a preview mod * refactor ModConfiguration class to work properly with client and server using child objects * move some Server constructor mod load code to ModConfiguration to reduce code duplication between client and server * remove mods.{cpp,h} unused functions * use UNORDERED_SET instead of std::set in some modspec storages --- src/client.cpp | 44 +++++++++++-- src/client.h | 3 +- src/mods.cpp | 197 ++++++++++++++++++++++++++++++--------------------------- src/mods.h | 57 ++++++++++------- src/server.cpp | 25 ++------ 5 files changed, 186 insertions(+), 140 deletions(-) (limited to 'src') diff --git a/src/client.cpp b/src/client.cpp index 3b8074252..4bb63fef1 100644 --- a/src/client.cpp +++ b/src/client.cpp @@ -268,14 +268,50 @@ Client::Client( void Client::initMods() { - std::string script_path = getBuiltinLuaPath() + DIR_DELIM "init.lua";
