Hi, I have a teleportation script I am working on, and I just can't seem to get it to run error free, no matter what safeguards I put in place. First off I just used a standard MVSF command, but on a regular basis it throws an "Unable to find safe location" error. My next attempt went like this: doif tmvf va00 va01 eq 1 mvft va00 va01 endi The idea of this being to check that the location was safe before moving the norn, but I am still getting regular invalid map position errors. I just don't get how it can be attempting to move the creature AFTER the script should have identified the location as unsuitable. Any help may save me from pulling out my hair. |

Do you run it all INST? When I remember correctly does each line run in an own tick when it is not INST. It might be that the creature changes it's pose just in the moment of teleport. Let's say it is sitting during the check, but standing during the actual moving, you get an error. With one tick being roughly 1/20 of a second it is of course not that likely that it happens, but it still can appear every now and then. Lets play plants! Photosynthesis... Photosynthesis... Photosynthesis... |

How is your script determining what va00 and va01 are? It might be a valid position, as determined by TMVT, but NOT a valid position for a creature, which are quite tall and bulky. The command is not testing for a safe location for the object being moved. And that's the key. Neither is the MVFT commander you're using to move the creature. So although it might be a valid position on the map, it is not a valid position for a creature. Suppose the ceiling is too low at that position, for example, or it's right next to a wall. It's a valid position, but a creature can't squeeze in there. Try using MVSF to move the creature just for testing purposes, to see if it finds a safe location. |

Argh, so obvious and I did not see! I didn't script for too long... Lets play plants! Photosynthesis... Photosynthesis... Photosynthesis... |

I thought of that...I added an object that was 140x140 pixels and use a TMVT to see make sure the object is safe moving there. I still get errors with pretty much the same regularity. (And just to be clear, all my teleport scripts happend while in INST) To be clear, the regularity is about 1 error for every 30 norn hours, but I have been running worlds with up to 70 norn running this script all the time, so it occurs about every 20 minutes. Not good enough. I feel I am running out of options! |

Can we see the script, or a good portion of it? |

Now I may have found a solution. I think the problem may have been caused by the script targeting the location of objects inside a carrying cabin (lifts etc.). I had been running a check on the MOVS of the creature being moved, but not on the destination object. The script works by RTAR a simple object like a toy, and moving the norn to that location if it was safe. The script seemed to be failing when the object was in a cabin, so I have to assume the object's world coordinates were calculated from inside the cabin. I have to run longer tests, but it seems to be working thus far. |
