A tool to pick a resource path (a string) with:

1. required types or interfaces
2. display a type instead of showing a string
3. pick a suitable object using a custom picker

Parameters:

• EStr eStr = EStr.Resource: which kind of string value you expected:

  • Resource: a resource path
  • AssetDatabase: an asset path. You should NOT use this unless you know what you are doing.
  • Guid: the GUID of the target object. You should NOT use this unless you know what you are doing.

• bool freeSign=false:

  true to allow to assign any object, and gives a message if the signed value does not match.

  false to only allow to assign matched object, and trying to prevent the change if it's illegal.

• bool customPicker=true: use a custom object pick that only display objects which meet the requirements

• Type compType: the type of the component. It can be a component, or an object like GameObject, Sprite. The field will be this type. It can NOT be an interface

• params Type[] requiredTypes: a list of required components or interfaces you want. Only objects with all the types can be signed.

• AllowMultiple: No

Known Issue: IMGUI, manually assign a null object by using Unity's default pick will assign an empty string instead of null. Use custom pick to avoid this inconsistency.
