Reputation: 39 Level up: 15%, 428 Points needed |   | | | Object Manager's reach
I tried searching for this answer with no luck. How far of a reach does the Object Manager have? That is, when you're looping through WoW's Object Manager and storing each object, what is the limitation for determining which objects are included and which are excluded due to them being out of a certain radius or zone? Are all of the objects in the player's current zone included in the OM?
I'm trying to decide how often I should append/update my GameObject lists as the player moves across the map. |

The updating also seems to be around 5 seconds, easily calculated while flying around on high speed air mount above icecrown while looking down, timing between mob spawns from area to area. |

So, there isn't an update speed or fixed radius for the client to receive new objects, they appear as you cross the boundaries of different cells. That said, there are some mobs and objects that are visible from a really long range, such as the Fel Reaver roaming in Hellfire Peninsula; I believe those specific ones might be visible from the whole zone. |

I meant that I was trying to figure out how many of the surrounding objects are stored in the Object Manager offset when I iterate through each object.
For example, if I loop through the OM while my player is in zone A, then move my player into a different zone B without reiterating through the OM, I assume there would be data discrepancies between the stored OM data and the actual objects in the new zone. It sounds like I would be okay to rescan the OM every time the player's zone changes. Or maybe I could store the player's XY position at the time of the OM loop, periodically compare it to his current XY position, and once the difference surpasses a certain distance (100 yard radius?), reiterate through the OM.

Wasn't going to bother explaining intricacies as it's fairly obvious, this thread is far below the level of using sort algorithms. |

Thanks for the reasons, surprised I posted such a crap question and didn't think for a second. |

@op: you should just update your lists each frame.
I got 7 lists that gets refreshed each frame, one for each objettype |

Update each frame = fine.
Updating 7 lists = baaaaaaaaaaaaaaaaaaad.
Use 1 list, and filter when needed. Tard. | | |
