[Taudier]

Hello ,

can you Help me ? How itempool does'it work ?

set m = CreateItemPool ()
call ItemPoolAddItemType(m,'I01Y',0.1 )
call ItemPoolAddItemType(m,'I01Z',0.5 )

When i ask to : call PlaceRandomItem(itempool,x,y)
it always drops the first item ( 'I01Y') . Why , what should i do ?

thanks .
