From 1aaee5b30d2c28e3256a0c8c3fc3784af91fb21b Mon Sep 17 00:00:00 2001 From: Paramat Date: Mon, 16 Jul 2018 04:57:44 +0100 Subject: Lua_api.txt: Various minor improvements (#7560) Add missing section title for 'Node paramtypes'. Clarify documentation for schematic Y-slice table. Document that schematic Y-slice behaviour does not invert for ceiling schematic decorations. --- doc/lua_api.txt | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/doc/lua_api.txt b/doc/lua_api.txt index 5e26921eb..2f8255cb4 100644 --- a/doc/lua_api.txt +++ b/doc/lua_api.txt @@ -929,6 +929,8 @@ They are represented by a table: them for certain automated functions.
