Getting an "Enum" value from a Scriptable Object
Hi! I'm trying to "get" the value of an enum variable using a property getter named "VisumBlueprintChallengeMode" inside a scriptable object so I can "set" it to an "Enum" variable named "challenge".
Here's my code where the error exists (Look for "TODO: Fix Error")

Here's the error I'm getting: Assets\Scripts\Editor\Consilio\Panels\VisumCreator.cs(111,29): error CS0266: Cannot implicitly convert type 'System.Enum' to 'BaesickEntertainment.Editor.Consilio.Panels.VisumCreator.Challenges'. An explicit conversion exists (are you missing a cast?) 
You made VisumBlueprintChallengeMode an Enum, so variable "_visumBlueprintChallengeMode" should be declared as
private VisumBlueprintChallengeMode _visumBlueprintChallengeMode;
The image isn't playing, but I imagined you want something in this context:
public enum Challenges { None, Freestyle, TimeAttack, Survival }
// The base class object
public abstract class EnumWrapper<T> : ScriptableObject where T : System.Enum {
public T value;
}
[CreateAssetMenu(menuName = "Blueprints/Challenge")]
public class ChallengeVisumBlueprint : EnumWrapper<Challenges> {
// Potential additional settings here
}
public class MyChallenge : MonoBehaviour {
public ChallengeVisumBlueprint challenges;
void Awake() {
switch (challenges.value) {
case Challenges.None:
break;
case Challenges.Freestyle:
break;
case Challenges.TimeAttack:
break;
case Challenges.Survival:
break;
default:
throw new ArgumentOutOfRangeException();
}
}
}
I taught getting enum values on SO are similar from getting other values on types like string or in (like this: scriptableObjectName.variableYouWantToGet) but it won't let me: Assets\Scripts\Editor\Consilio\Panels\VisumCreator.cs(111,29): error CS0266: Cannot implicitly convert type 'System.Enum' to 'BaesickEntertainment.Editor.Consilio.Panels.VisumCreator.Challenges'. An explicit conversion exists (are you missing a cast?)
