Changing a Scriptable Object's Variables without effecting other instances.

Hi, second time posting. I hope this is the correct category for this question.

So I'm making a Looter Shooter, similar to Destiny or Borderlands. However, I'm having an Issue with random rolls on weapons.

Let me explain:

Let's say you get a drop from an enemy, it will give you a random weapon type from its lootpool. The part that is an issue is when I attempt to add random stats to a weapon it applies those changes to all weapons of that type.

I.E. You get an AR with the perk Swiftness, and it changes the perk set on all the ARs previously accquired to have that stat.

The original implementation before I realized this issue was this:

if (item.hasRandomRolls)
{
item.activePerk1 = item.perkSlot1[UnityEngine.Random.Range(0, item.perkSlot1.Count - 1)];
if (item.hasTwoPerks)
{
item.activePerk2 = item.perkSlot1[UnityEngine.Random.Range(0, item.perkSlot2.Count - 1)];
}
}

I tried to fix it by creating a new item of the Gun scriptable object, adding a middle-man:

Gun item = new Gun();
item = pickup
if (item.hasRandomRolls)
{
item.activePerk1 = item.perkSlot1[UnityEngine.Random.Range(0, item.perkSlot1.Count - 1)];
if (item.hasTwoPerks)
{
item.activePerk2 = item.perkSlot1[UnityEngine.Random.Range(0, item.perkSlot2.Count - 1)];
}
}

However, both resulted in the same conclusion: the change in all the previously acquired weapons as the newest stat roll is acquired.

My hypothesis:
When I go and apply the perks, it applies it to the scriptable object class that it derives from. My second attempt was created as a way to make another scriptable object instance in order to receive the new stats without changing the currently acquired weapons. However, since object = statements are just adjusting references to memory, it is effected by the change as well.

The ideal scenario:
I can just create a new instance of the Gun scriptable object, keeping the base characteristics of the weapon itself while changing the active perk variable in order without affecting other weapons of the same type in inventory.

If there is a usable solution it would be greatly appreciated.

 

You can use

ScriptableObject.CreateInstance<>();

to create an instance to use.

It's not optimal however, as you are conflating the idea of ScriptableObjects (authored when making the game) with runtime data.

I actually just wrote a big post about it here:

Thank you!
