Lua question...

GregBUG

sorry guys i need a little help...
i'm not an expert in Lua coding but
why in this code

function TestInit() TestList = {} end   function TestCreate(name, xPos, yPos, Direction, parentGroup) local TTest = { name = name, xPos = xPos, yPos = yPos, Direction = Direction, anotherList = {}, parentGroup = nil } TestList[name] = TTest TestList[name].name = name TestList[name].xPos = xPos TestList[name].yPos = yPos TestList[name].Direction = Direction TestList[name].parentGroup = parentGroup return TestList[name] end   function TestDone() for key,value in pairs(TestList) do value.anotherList = nil TestList[key] = nil end TestList = nil end   -- test print ("memory used:"..collectgarbage("count")) TestInit() TestCreate("ciao", 10,10,33,nil) TestCreate("ciao3", 10,10,33,nil) TestCreate("ci22", 220, 410, 56, nil) TestCreate("ci232", 220, 410, 56, nil) TestDone() print ("memory used:"..collectgarbage("count"))

there is a memory leak?
in testDone() function i nil all tables and other ref. !

Hi,

In fact, there is no memory leak. Just call collectgarbage() before printing collectgarbage("count")

--...............   -- test collectgarbage() print ("memory used:"..collectgarbage("count")) TestInit() TestCreate("ciao", 10,10,33,nil) TestCreate("ciao3", 10,10,33,nil) TestCreate("ci22", 220, 410, 56, nil) TestCreate("ci232", 220, 410, 56, nil) TestDone() collectgarbage() print ("memory used:"..collectgarbage("count"))
