From ab433775777c4f5055bcf4d2a1cffc506c4f9961 Mon Sep 17 00:00:00 2001 From: sapier Date: Sat, 25 May 2013 00:51:02 +0200 Subject: Move scriptapi to separate folder (by sapier) On the lua side, notably minetest.env:() should now be replaced by minetest.(). The old way is and will stay supported for a long time. Also: Update and clean up lua_api.txt (by celeron55) Move EnvRef to lua and remove add_rat and add_firefly (by kahrl) Add separate src/util/CMakeLists.txt, other minor fixes (by kahrl) --- src/script/lua_api/l_particles.cpp | 149 +++++++++++++++++++++++++++++++++++++ 1 file changed, 149 insertions(+) create mode 100644 src/script/lua_api/l_particles.cpp (limited to 'src/script/lua_api/l_particles.cpp') diff --git a/src/script/lua_api/l_particles.cpp b/src/script/lua_api/l_particles.cpp new file mode 100644 index 000000000..c291cc21e --- /dev/null +++ b/src/script/lua_api/l_particles.cpp @@ -0,0 +1,149 @@ +/* +Minetest +Copyright (C) 2013 celeron55, Perttu Ahola + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU Lesser General Public License as published by +the Free Software Foundation; either version 2.1 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
