Best way to add setup prefab with dependency to other prefab instance

Hi,

Let's say I have a different gun prefabs like RailGun, LaserGun, etc.

Each of those prefabs shoot projectiles like LaserProjectile, RailProjectile, which depend on correct projectile pool prefab to store a pool of 10 pre-Instantiated projectiles.

So I have LaserProjectilePool which holds LaserProjectile etc.

So right now I do something like this:

1. Add LaserGun prefab to the scene and make it child of a Player object

2. Add LaserProjectilePool to the scene globally (unrelated to Player) object

3. Link LaserProjectilePool to LaserGun in the scene ... and I do it for each type of gun / pool. Also I have different kinds of pools for explosions like LaserExplosionPool and so on.

What's the best/automatic way to ensure I have both of those and linked automatically in the scene, without too much coding?

What comes to my mind:

• add OnEnable logic which Instantiates the pool if it doesn't exist

• add a custom editor button "Create Pool if Doesn't exist" for prefab with dependency

• add a custom editor button "Find All Guns and Assign Pool"

• use some plugin like PrefabInstance ?
