Hi all, I have the following setup:
I have a custom class which is linked via inheritance to ScriptableObject, and then which I extend with specific classes that contain specific behaviour, like this:
ScriptableObject -> PluginEffect -> SomeSpecificEffectScriptIWrite
I then have what are called 'behaviour' scripts which I attach to objects. All these scripts do is provide an exposed public member to the editor, of type PluginEffect. After I've used a tiny editor script to create a ScriptableObject asset of type 'SomeSpecificEffectScriptIWrite' I then drag this new asset into that exposed field and at runtime the behaviour script calls methods on it magical things (are meant) to happen.
I do this so that I can have a fairly generic drag/drop system whereby I can interchange numerous hardcoded behaviours between objects and they just work nicely. Now when testing with multiple objects, I realised that only one of them will process the ScriptableObject, so for example if my class 'SomeSpecificEffectScriptIWrite' creates a load of explosions and smoke and fire around the object that uses it, and I have 3 objects that all reference this via the inspector who all die at the same time, well, only one of them (the last one to die as it takes control of the reference) processes that code and runs. This is clearly not going to work out and isn't what I want. So upon discovering this, I used ScriptableObject.CreatInstance(); to make a new instance, this worked, except, it uses all default settings as set in the code, which won't work for my purposes because I need to set colours, effect types, sizes, durations, references to objects and prefabs and so on.
So the problem I am having is in trying to clone this reference to my specific PluginEffect. I have now tried this:
Which actually works, in that it gives me an new clone with the settings I set in the inspector and even if multiple objects use it, they can do so without stealing control of it away from another object - of course, since it's a proper clone. The downside of this is that I get a mystical error message:
Which I have not even the slightest idea of where to start. Searching yields nothing other than a post relating to GUIStyles which says you shouldn't use Instantiate to clone an asset. It says to use CreateInstance(). Which as mentioned I've tried and it doesn't work for my needs, as it doesn't use any settings I've set in the editor on my ScriptableObject asset.
So now I'm a bit lost as to where to go. Someone suggested using the 'new' keyword, but I do not know how to do that when I have a reference to my class, I can of course do:
But that won't have my settings from the inspector or more importantly be of the 'SomeSpecificEffectScriptIWrite' class with it's unique behaviours. I can't do:
Because I don't know what class that is in code - I drag it onto the public method via the inspector. So perhaps I am either missing something obvious, or I am trying to do something that this ScriptableObject class is not meant for, I'm not sure and would appreciate some insight. Also apologies if this is complicated to follow, I did struggle trying to explain it and this is the best it has come out as. Thanks.

This probably doesn't help, but why not just use prefabs/monobehaviours to accomplish this?
You could set up something similar to how you have it, where you have a class hierarchy of monobehaviour -> plugineffect -> yourspecialeffecttype. That way you can instantiate an instance of your special effect object and seemingly solve your problems.
