EnableIf / DisableIf

Can be used to make serialized fields or buttons readonly based on some condition. The condition can be a field, property or function.

Note

If you want to use it on fields that are nested inside serialized structs or classes you need to use the AllowNesting attribute.

public class NaughtyComponent : MonoBehaviour
{
    public bool enableMyInt;

    [EnableIf("enableMyInt")]
    public int myInt;

    [EnableIf("Enabled")]
    public float myFloat;

    [EnableIf("NotEnabled")]
    public Vector3 myVector;

    public bool Enabled() { return true; }

    public bool NotEnabled => false;
}

You can have more than one condition:

public class NaughtyComponent : MonoBehaviour
{
    public bool flag0;
    public bool flag1;

    [EnableIf(EConditionOperator.And, "flag0", "flag1")]
    public int enabledIfAll;

    [EnableIf(EConditionOperator.Or, "flag0", "flag1")]
    public int enabledIfAny;
}

An enum value can also be used as a condition:

public class NaughtyComponent : MonoBehaviour
{
    public EMyEnum enumFlag;

    [EnableIf("enumFlag", EMyEnum.Case0)]
    public int enableIfEnum; // Will be enabled only if enumFlag == EMyEnum.Case0
}

public enum EMyEnum
{
    Case0,
    Case1,
    Case2
}
