Is it possible to determine the owner of any given missile?

[PM]

For example, use (enum (sysFindObject ...) thisObj ...) to determine which beams and missiles among a list are mine and which are not, then do something to those missiles that are not mine.

 I’m not sure about the specific owner of a beam/missile, but a quick test shows that I can at least get their sovereigns. Depending on how you’re wanting to use it — such as something only the playership would have, or something where it makes sense not to have the item in question affecting beams/missiles from the same sovereign — might that be enough to do the trick?

I need to know the specific owner of any given missile object for what I want to do. Detection shortcuts like sovereign or player-only will not work.

Easy with the help of a virtual station and <OnSystemWeaponFire>:

Code: Select all

<OnSystemWeaponFire>
	<!-- 
	
	Populated variables:
	
	aWeaponObj: is the object that fired the weapon.
	aWeaponUNID: is the UNID of the weapon being fired.
	aWeaponPos: is the position where the shot originated.
	
	-->
	
	(block (aShot)
		(setq aShot (sysFindObject aWeaponPos "mb NN:1"))
		(objSetData aShot "owner" aWeaponObj)
	)
</OnSystemWeaponFire>

The key idea is to tag each shot with its owner spaceObj as soon as it's fired. I know you know how to implement the rest.

Ah, yes, that trick. I hoped I would not need to resort to virtual stations to force feed such data. Thanks, anyway.

The data's available in the damage events so it may be in object properties if George will reveal the identifier. If it isn't it's something you can request that shouldn't be too hard to implement.

Unfortunately, when I want the data is not within an event where aAttacker is available. It is within a recurring event akin to OnBehavior.
