Elder Scrolls Forum: Making recall behave like travel service

I will appologize beforehand here, cause I'm about sick of hearing this...

My own inadequacies maybe...

As far as I know, the Partners mod has a recall option.

As far as I know, MentalElf has done a packguar mod that has an option that allows the player to "call" the guar from a defined location (home???) to the player's current location.

Both of these mods recall to exteriors only.

Reason: Exterior locations are on one coordinate grid, so when you say location x, y, z, in script, the game engine can then make a determination of the correct position and use those coordinates to place the object via the SetPos function.

SetPos allows the use of variables. As far as I know, Position does not. Those are the only two functions available for use in placing objects around the gameworld, and if you want to bring a companion to the player's position, then you have GOT to define the player's coordinates via variable with GetPos.

Every interior has it's own set of coordinates though, so you cannot use the same operation to recall to an interior. Reason we have both Position (for exteriors), and PositionCell (for interiors). Position only requires the coordinates be defined because Position only works for the exterior coordinate grid. PositionCell requires that both the coordinates and cell name be defined because interiors have their own coordinate grid, different from the "world" grid.

So, as far as recall goes...

set player_x to ( Player->GetPos x )

...works.

Companion->SetPos x to player_x

...works.

Companion->Position playerx, player_y, player_z, zrot

...does not work.

You can use defined coordinates with position, but not variables. In other words...

Companion->Position 1234, 5678, 910, zrot

...works, but the coordinates have to be defined as intergers in script. The coordinates cannot be defined on-the-fly, in-game, with variables as can be done with SetPos.

According to the devs, moving an object over multiple cells creates problems. My own experiments have not worked well when trying to use SetPos across anything other than a 3 x 3 cell block. The reason simple warping works: It is generally confined to the current cell.

Any kind of recall is generally going to try and move the object a distance farther than the currently loaded block (current active cell + one cell on each side of that cell (3 x 3 block)).

I assume the two above mentioned mods use the GetPos/SetPos functions to accomplish their recall function. The general outline for this operation was first defined by Aftershock_81 and generally uses either a "fixme" command (or two), or a disable/enable statement in script to "repaint" the object upon arrival at the new cell (the object will not load correctly if you don't).

I tried this, but had many problems wit it. Apparently I wasn't holding my mouth right, cause both of these mods use a variation of Aftershock_81's original idea, and apparently it works. I haven't seen any problems mentioned on the forums so far concerning this operation.

...and agian...

...because of the restrictions mentioned above, only in exteriors.
