SSE Follower will not stay mounted - scripting help

[Sanitatem]

Hi all,

I am trying to get my follower Moranya to ride a horse that teleport to her when the player rides a horse. I have set up a horse riding quest, and placed a script on the player alias. I adapted the script from a smiliar topic I found on the nexus forums. My follower has a horse riding package with min radius set to 300, max radius set to 1000, ride horses if possible set to yes. My horse, Sirora, has Moranya registered as its owner.

At the moment the Moranya is able to get on the horse, but the second my player moves forward (on his horse) she will dismount and run after him. If I stay put after mounting the horse, she will stay mounted and will only dismount when I do. Please help!

Script is below:



Scriptname MR01MountTest extends ReferenceAlias
Faction Property CurrentFollowerFaction Auto
Actor Property Siroria Auto
Actor Property Moranya Auto

Actor Player
ReferenceAlias Property MoranyaRef Auto
Event OnInit()
Player = Game.GetPlayer()
RegisterForAnimationEvent(Game.GetPlayer(), "tailHorseMount")
RegisterForAnimationEvent (Game.GetPlayer(), "tailHorseDismount")
Debug.Notification ("Events registered")
EndEvent

Event OnAnimationEvent (ObjectReference akSource, string asEventName)
If akSource == Player
Else
Return
EndIf

If Moranya.IsInFaction(CurrentFollowerFaction) ==1
If Moranya.GetActorValue("WaitingForPlayer") == 0

If asEventName == "tailHorseMount"
Debug.Notification ("Player mounted")
Siroria.MoveTo(Moranya as objectreference, 50.0000 \* math.sin(Moranya.GetAngleZ() + 90.0000), 50.0000 \* math.cos(Moranya.GetAngleZ() + 90.0000), 0.000000, true)
Moranya.OnAnimationEvent(none, "tailHorseMount")
Siroria.Activate(Moranya)
Moranya.EvaluatePackage()
EndIf



If asEventName == "tailHorseDismount"
Debug.Notification ("Player dismounted")
Moranya.Dismount()
Moranya.EvaluatePackage()
EndIf
Else

Return
EndIf
EndIf
EndEvent

We assume it is a player alias script. Maybe something like this:

 

MR01MountTestAliasScript

 

Scriptname MR01MountTestAliasScript extends ReferenceAlias

Thank you for the help! The player mounted debug notifications do not show unfortunately, and the horse is not appearing at all. Do I need to change anything in bool bOK? Is bOK supposed to reference something?

[ReDragon2013]

The bool "bOK" is a function parameter and result in

bOK = asEventName == "tailHorseMount"

it can be TRUE (asEventName is tailHorseMount)

or False (asEventName is tailHorseDismount)

 

Why can be this? You only registered two animations (by the same reference) for the OnAnimationEvent().

 

 

In case you do not really have papyrus knowledge take the script you posted and change next part

Siroria.MoveTo(Moranya as objectreference, 50.0000 \* math.sin(Moranya.GetAngleZ() + 90.0000), 50.0000 \* math.cos(Moranya.GetAngleZ() + 90.0000), 0.000000, true)

to this

float f = Moranya.GetAngleZ() + 90.0
Siroria.MoveTo(Moranya as Objectreference, 50.0 * Math.SIN(f), 50.0 * Math.COS(f),  0.0, TRUE)

You wrote: "The player mounted debug notifications do not show.."

Whatever you do with papyrus please inspect the logfile "papyrus.0.log" as well, because of papyrus runtime errors or output of native function Debug.Trace().
