player.cursor_stack ~= nil always true?

[oLaudix]

Code: Select all

if player.cursor_stack ~= nil then
	game.player.print(player.cursor_stack.name)
else
	return
end

As long as i have item in my "hand" it works. If I change item for an item it works fine as well. But when i put item in empty slot and my hand is empty it throws exception at "game.player.print(player.cursor_stack.name)". But from what i understand it shouldn't even get to that part of code if my hand is empty?

0.12 changes:

Changed LuaEntity::stack, LuaEntity::held_stack and LuaPlayer::cursor_stack to return LuaItemStack objects.
Changed LuaItemStack to allow reading any inventory slot even when the item in the slot is invalid. LuaItemStack::valid_for_read should be used before accessing the normal properties/methods for a given LuaItemStack.

if player.cursor_stack.valid_for_read then ...
should be the new way to do it

It works great now. Thank you.
