How to check if an object is empty

  • #1, by GingetsuryuuTuesday, 16. April 2013, 18:59 11 years ago
    local object = getObject('Game.GameSavedObject')
print(tostring(object))
if object ~= nil  then
  getObject('Conditions[Hover item]'):setValue(VConditionValue,false)
else
  getObject('Conditions[Hover item]'):setValue(VConditionValue,true)
end


    The code is supposed set the Hover item condition to true if the GameSavedObject is not empty.

    18:52:57: ---Empty---
    18:57:35: Razor (6,14)

    That's the log: The first entry is when GameSavedObject is empty, the second is when the GameSavedObject is set to an object. But regardless of this, the Hover item always returns false.

    ~= nil: is does not equal nil ...


    either set it as == or change the getObject true/false values the other way around.
    currently you have it saying false for when object does not equal nil.

    I changed it to 

    local object = getObject('Game.GameSavedObject')
if tostring(object) == "---Empty---"  then
  getObject('Conditions[Hover item]'):setValue(VConditionValue,false)
else
  getObject('Conditions[Hover item]'):setValue(VConditionValue,true)
end


    Which works, but I'm not sure that converting it to string and then comparing it to "---Empty---" is an effective way of doing it.
