Make a field in inspector hold inheriting classes
Hello,
I was wondering if it was possible for a field in the Inspector to change between different classes that extend the given field type.
What I mean is, I have a Weapon class, I also have Gun and Melee, which both extend Weapon. Gun and Melee have their own specific variables but also use some of Weapon's variables.
What I want is for some other script, to have a public variable of type Weapon, and I want to be able to be able to use either a Gun or a Melee inside the field in the Inspector. (So that I am able to edit the variables for that weapon in the inspector no matter what the weapon "type" is).
Here's a quick example
public class Weapon{
public string weaponName;
}
public class Melee : Weapon{
public float range;
}
public class Gun : Weapon{
public float ammoCapacity;
}
public class Attack : MonoBehaviour {
//Can I (inside the Inspector), use a Gun or Melee instead of being forced to a basic Weapon
public Weapon weapon;
}
Thanks!
You could make your weapon class a ScriptableObject. Then you would have to create weapons as assets and drag and drop them :
[CreateAssetMenu (fileName = "New Generic Weapon.asset", menuName = "Generic Weapon")]
public class Weapon : ScriptableObject
{
public string weaponName;
}
[CreateAssetMenu (fileName = "New Melee.asset", menuName = "Melee")]
public class Melee : Weapon
{
public float range;
}
[CreateAssetMenu (fileName = "New Gun.asset", menuName = "Gun")]
public class Gun : Weapon
{
public float ammoCapacity;
}
The only limitation, is that ScriptableObject are only references, so changing one changes them all. Which can also be handy.

By that, do you mean, that I have to create a new script/class for each separate weapon that I want to make?
Ok, I found a great tutorial for this! https://www.youtube.com/watch?v=ItZbTYO0$$anonymous$$nw Thanks a lot!
Not a new script/class, but a new asset. Though, using the implementation suggested by @Adam-$$anonymous$$echtley solves this.
What you're asking about here is polymorphic serialization, which is not supported. I have answered similar questions e.g., here, discussing possible workarounds.
Scriptable Objects was the way to go! Thanks for the help! I ended up using this video to make my Scriptable Objects https://www.youtube.com/watch?v=ItZbTYO0$$anonymous$$nw
