Talk:SetPos

I added some additional information that helped me in the process of scripting my mods.--Omzy 11:50, 13 June 2006 (EDT)

Setting this value via computations does not work. Instead, use GetPos with computations and use the result as a variable for SetPos.

This does not work:

SetPos X (GetPos X + 40)

This works:

short xPos
Set xPos to (GetPos X + 40)
SetPos X xPos

What's the point of this info? No Function accepts expressions as parameters.--JOG 12:11, 13 June 2006 (EDT)

Dragoon Wraith TALK 14:36, 13 June 2006 (EDT): Is that fact anywhere on the Wiki? Because I didn't realize that for a while...

Well, it's implicit that only those things work that are specified as working, when we find out something that wasn't mentioned before we add it, but there is no point in adding info to random functions that things from other programming languages don't work here. There are no arrays, no sub-procedures, no default values on variable definition, no control structures besides if, and so on...--JOG 15:33, 13 June 2006 (EDT)

If you're having a problem getting light to shed properly after updating its position using SetPos, here is a solution using a combination of MoveTo, SetPos, a persistent Light Form, and a Dummy Cell:

Begin GameMode

  PersistentLightReference.PositionCell 0 0 0 0 DummyCell
   ; Using PositionCell because SetAtStart did not work,
   ; though using a Marker in conjunction with MoveTo might- didn't test

  PersistentLightReference.Disable
  PersistentLightReference.MoveTo Player
  Set PlayerPosX to Player.GetPos X
  Set PlayerPosY to Player.GetPos Y
  Set PlayerPosZ to Player.GetPos Z
  PersistentLightReference.SetPos X PlayerPosX
  PersistentLightReference.SetPos Y PlayerPosY
  PersistentLightReference.SetPos Z PlayerPosZ
  PersistentLightReference.Enable

End

You could conceivably use another MoveTo in conjunction with a Marker instead of PositionCell, but this method is simpler.

This is just the core of the solution, of course. You'll have to declare the Floats PlayerPosX/Y/Z, place a persistent Light, make a Dummy Cell to move to and from, and replace any references or set up any conditionals in the GameMode block that you need for your particular application. For those of you who are still confused, the exact implementation is included in my Wieldable Torches mod.--The Munchkin Lord 23:06, 25 February 2007 (EST)

I think only the Disable/Enable is necessary in combo with the MoveTo as it may be needed to reset their collison meshes(?) I have had CTD's [for some objects] when I used Enable/Disable in the same frame. If you have such trouble then spilt them so they are called on successive frames. GuidoBot 22:58, 11 April 2007 (EDT)
