Is this possible? Drag-and-drop in editor for resource path only, not object reference

Hi,

Could some sort of editor property type be made, where, when you drag a resource object into it, the property, the actual field of which would be a string value, would be set to the resource path, and not as a reference to that resource?

My motive is that as I do know that any resources, when they are scene-linked to components, the resource will actually be loaded to memory when the object is loaded, and I would like to avoid this. However, I would like to have the visually explanative, designer-friendly power of the component configurations in-editor, instead of configurations being hidden deep into nested classes in code, or in some external files that you need to open and investigate, etc. etc.

Also, if it would be possible to have the resource highlighted when pressing on the editor field would be absolutely great.

Any info on this?

Hey there,

Yes this is quite easy to do in fact. You can see the example I attached. You just keep your paths as string references but when you look at the object the inspector uses Resources.Load or AssetDatabase.load and displays an object field.If the user changes the object you get the path of the new object and save it to the string path reference.

You can take this one step further and and check if the path is valid (if it's in the resources folder) and even try to find the object if it has moved.

Sorry to dig up this old post, but is this post maybe missing your code example? I for one would like to see it

 

This is a super old thread but I get questions about it all the time. So I just made a public Github repository for AssetPathAttribute.

Oooo this was so close to what I was after. I don't suppose anyone would know if this can be tweaked to work with Scene files? Tried using a Scene type but it just returns null on the Object when selected (which I guess makes sense). I want to set up levels by dragging in the scene that it uses and just can't find a solution.

 

Well a little late now but yes there is now a `SceneReference` type in the repo.

 

Thank you for the great asset!

 

Does it work for arrays?

 

Just checked. Its great! Thanks for your job.
