How to use a trigger to detect player and other actors ?

[Delzaron]

Hi

 

I met an interesting problem :

 

Once I activated a trigger, I need to check :

- if player is still inside after an amount of time.

- if this trigger contains a follower.

 

How I can do that, please ? Thanks in advance.

Handle the two events of the trigger:

 

OnTriggerEnter(ObejctReference akRef)

 

OnTriggerLeave(ObjectReference akRef)

 

 

Add a variable to the script (maybe a property if you need to check from another script):

 

bool isPlayerInside

 

 

in OnEnter, check if the akRef is PlayerRef, if yes then set the boolean to true, and start a quick OnUpdate, e.g. RegisterForSingleUpdate(10.0)

 

In the OnUpdate, check the boolean for the player is still true, and increment the seconds, and re-register.

 

When the player leaves, put the boolean to false, and resent the conuter, and stop for Updates.

 

Example:

 

Scriptname myTrigger extends Activator
 
Actor Property PlayerRef Auto
bool Property isPlayerIn Auto
bool Property hasBeenInFor2mins Auto
int numSeconds
 
Event OnTriggerEnter(ObjectReference akRef)
  if akRef==PlayerRef && !isPlayerIn
    isPlayerIn = true
    hasBeenInFor2mins = false
    numSeconds = 0
    RegisterForSingleUpdate(10)
  endIf
endEvent
 
Event OnTriggerLeave(ObjectReference akRef)
  if akRef==PlayerRef && isPLayerIn
    isPlayerIn = false
    hasBeenInFor2mins = false
    numSeconds = 0
    UnregisterForUpdates()
  endIf
endEvent
 
Event onUpdate()
  numSeconds+=10
  hasBeenInFor2mins = (numSeconds>120)
  if isPLayerIn
    RegisterForSingleUpdate(10)
  endIf
endEvent

That's a very complex script...

 

So, how I can trigger a function ?

For example, if player is still in the trigger, something will happen... like death, skeever rape, etc... ?

 

How I can checl if a follower is present in that trigger too ?

For followers, you can convert akRef to actor, and then check .isPlayerTeamMate()

 

 

To trigger actions is just scripting.

If you have a function in one of your Quests, then just put a reference to the Quest (a property) and then call the function you like.

You're a god ! I never thought about using booleans...

 

I will try your solution soon as possible ! Thanks !
