A Question About The "OnLoad" Commands

[AlexxEG]

Let's say a object have a script that goes

Begin OnLoad
PlaceAtMe Explosion
End

(I don't realy have that as the script, it's just a example)

If I then use "PlaceAtMe ObjectsFormID", will the script trigger when it's spawned?

No it won't as the OnLoad block runs once when a cell is loaded, not an object. You could just use this instead:

 

scn MySpawnedExplosionScript

Short DoOnce

Begin GameMode
 If DoOnce == 0
   PlaceAtMe Explosion
   Set DoOnce to 1
   disable            ;Makes the spawned item vanish
   markfordelete      ;will remove the item from the game permanently after a few frames
 EndIf
End

Ahhh.... Okey thanks^^

Though, for reference, explosion type objects automatically mark themselves for deletion after their duration expires, so in this particular instance you wouldn't need markfordelete. Most other object types you do, though.

OnLoad blocks will run when the scripted reference is loaded into memory. This can happen when the player enters the cell containing it, or when it is moved to the player's location from a distance cell, or when a previously disabled object is enabled (for objects with 3D data).

 

In some cases, OnLoad blocks won't run because an object may already be loaded in memory. For example, if I start Fallout 3 and load a save in which a reference with the following script attached to it, the global "TimeScale" variable will be set to 5:

ScriptName InitTimeScaleScript

Begin OnLoad
set TimeScale to 5
End

However, if I then load that same save from in-game, the value of "TimeScale" will be read from the save, but because the object is already loaded its OnLoad block won't run again, so "TimeScale" won't be updated.

 

For this reason, I usually recommend avoiding this blocktype - the fact that it can be ignored so easily makes it pretty useless in most cases.

Got it ;) However, if a object have 3D Data, what does that mean? Totaly off-topic btw

[Cipscis]

Just about every object will have 3D Data. A notable exception (and the only example that I can think of) would be a trigger box. As far as I know, if an object has a mesh associated with it then it has 3D Data.

OnLoad blocks will run when the scripted reference is loaded into memory.

 

I did not know this, Thanks again Cipscis.

Okey, thanks for all the help from all three of you^^
