UnitUserData/Struct Question

07-30-2007, 08:59 PM

is there a way to destroy a struct attached via SetUnitUserData() after it dies? I tried

JASS:

function SomeFunction takes nothing returns nothing
local unit killed             = GetTriggerUnit()
local mobdata mobd         = GetUnitUserData(killed)


call mobd.destroy() //Get rid of the struct

but Grimoire gave me "attempt to destroy null struct of type" error. Any way around this? or am I going to have to use CSData?

Vexorian	I don't remember correctly but it looks like killing a unit breaks cleans its userdata? In that case you can try to catch the life becomes 0 event (which is hard to deal without leaks) or use an alternative to UnitUserData

Beardo	I thought so CSdata should work though, right?

Beardo	Changed it to CSData. Now I get a double free warning when I try to destroy it Does CSData automatically clear itself when the unit dies or what?

Vexorian	You are most likely doing something wrong, would have to see some code.
