    Memory leaks

    I'm using
    local monitorMem = function()
    collectgarbage()
    print( "\nMemUsage: " .. collectgarbage("count") )
end
    stage:addEventListener(Event.ENTER_FRAME, monitorMem)

    To track memory leaks. I'm spawning a box2d sprite, removing it's physics fixture and body, then removing the sprite from the scene. But my memory usage slowly ticks up and up as each sprite is added and removed.

    What are some other things that could cause this?

    I think I'm removing the timers and event listeners correctly...

    Thanks

      There was something about that collectgarbage does not free the memory instantly, it takes some time. Or you could call collectgarbage function multiple times to free memory sooner. But without seeing your code, I don't know if this is the case.

      Tom > Do you see any differences with the following :
      local floor = math.floor
local monitorMem = function()
     collectgarbage()
     collectgarbage()
     collectgarbage()
     print("MemUsage: ", floor(collectgarbage("count")))
end

      Thanks for the help.

      I think I have found the problem - each sprite had a timer attached. Adding timer:stop(); seems to have fixed things.

      Thanks again.
