i have a global table indexes in this table are actor's IDs, so they stand not in a serial row as i know the "for i = 0, #table do" cycle will stop if tried to acces a nil element how can i cycle through the whole table? maybe table.foreach? |

"for i = 1, #table do" will cycle through all of the table's non-nil items, even if it bumps into a nil one in the middle of cycling. |

ok, i'll try again another question: is there any sense in using table.remove and table.insert? |

Insert and remove can shift existing elements. You can read about it here: Lua 5.1 Reference Manual: Table insert One important thing that you may or may not be aware of: Lua Docs wrote: An unsigned char specifying the MOID that this MovableObject is assigned for the current frame only. |

Question: Why store actor IDs at all? Why not just GetMOFromID so you have a stable pointer rather than an unstable MOID? |

That's probably not a great way to make programming decisions. |
