From 96c4fb60d8641b4181edb902ed24dbf173828d09 Mon Sep 17 00:00:00 2001 From: iliekprogrammar Date: Sat, 13 Nov 2021 10:46:16 +0800 Subject: [PATCH] Fix crash on startup during immediate runtime by mcl_burning The crash occurs if mcl_burning:data is deserialized to nil. The cause of mcl_burning being set to "return nil" is unknown. Therefore, when it occurs, it will be logged as warning. --- mods/ENTITIES/mcl_burning/init.lua | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/mods/ENTITIES/mcl_burning/init.lua b/mods/ENTITIES/mcl_burning/init.lua index 313e75dca..a47824537 100644 --- a/mods/ENTITIES/mcl_burning/init.lua +++ b/mods/ENTITIES/mcl_burning/init.lua @@ -44,18 +44,18 @@ minetest.register_on_respawnplayer(function(player) mcl_burning.extinguish(player) end) -minetest.register_on_joinplayer(function(player) - local storage - - local burn_data = player:get_meta():get_string("mcl_burning:data") - if burn_data == "" then - storage = {} - else - storage = minetest.deserialize(burn_data) +function mcl_burning.init_player(player) + local meta = player:get_meta() + -- NOTE: mcl_burning:data may be "return nil" (which deserialize into nil) for reasons unknown. + if meta:get_string("mcl_burning:data"):find("return nil", 1, true) then + minetest.log("warning", "[mcl_burning] 'mcl_burning:data' player meta field is invalid!
