Like Required, but only required if the condition is a truly result.

Parameters:

Arguments:

• (Optional) EMode editorMode

  Condition: if it should be in edit mode, play mode for Editor or in some prefab stage. By default, (omitting this parameter) it does not check the mode at all.

  See Misc - EMode for more information.

• object by...

  callbacks or attributes for the condition.

• Allow Multiple: Yes

You can use multiple RequiredIf. The field will be required if ALL condition is true (and operation)

For multiple RequiredIf: The field will be required if ANY condition is true (or operation)

It also supports sub-field, and value comparison like ==, >, <=. Read more in the "Syntax for Show/Hide/Enable/Disable/Required-If" section.

You can use Required to change the notice message & icon. See the example below

using SaintsField;

[Separator("Depende on other field or callback")]
public GameObject go;
[RequiredIf(nameof(go))]  // if a field is a dependence of another field
public GameObject requiredIfGo;

public int intValue;
[RequiredIf(nameof(intValue) + ">=", 0)]
public GameObject requiredIfPositive;  // if meet some condition; callback is also supported.

[Separator("EMode condition")]

[RequiredIf(EMode.InstanceInScene)]
public GameObject sceneObj;  // if it's a prefab in a scene

[Separator("Suggestion")]

// use as a notice
public Transform hand;
[RequiredIf(nameof(hand))]
[Required("It's suggested to set this field if 'hand' is set", EMessageType.Info)]  // this is now a config provider
public GameObject suggestedIfHand;

[Separator("And")]

// You can also chain multiple conditions as "and" operation
public GameObject andCondition;
[RequiredIf(EMode.InstanceInScene, nameof(andCondition))]
public GameObject instanceInSceneAndCondition;  // if it's a prefab in a scene and 'andCondition' is set

[Separator("Or")]

// You can also chain multiple RequiredIf as "or" operation
public GameObject orCondition;
public int orValue;
[RequiredIf(nameof(orCondition))]
[RequiredIf(nameof(orValue) + ">=", 0)]
public GameObject requiredOr;  // if it's a prefab in a scene and 'andCondition' is set
