Allow using Make Sub-Resources Unique when selecting multiple nodes

[pc9098]

Describe the project you are working on

2D game similar to nuclear throne

Describe the problem or limitation you are having in your project

When I copy several nodes and paste them I have to select one of them and make its resources unique and then the next one, and then the next, etc

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Make sub-resources unique could also work for several selected nodes

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

the "Make sub-resources unique" in the Inspector will also show up if several nodes are selected

If this enhancement will not be used often, can it be worked around with a few lines of script?

The only workaround is going one by one, which is impractical

Is there a reason why this should be core and not an add-on in the asset library?

This change will affect all of us in a better way, so it would be better if all had it

If you want a workaround, resources are made unique when nodes are copied to another scene. So you can copy your nodes somewhere else and copy back.

Thanks. I did not know that. Since that workaround is pretty unintuitive I'm going to keep this post because having that option would be more practical

I also advocate for the possibility of unique duplicates (including all sub-resources). Ideally in the form of the shortcuts Ctr+D and Ctrl+Shift+D.

Today I also faced a similar issue. Using Ctrl+D to duplicate grass instead of Instancing new grass scene made all duplicated grass destroy together when one of them is destroyed. This behavior is very unintuitive for me.

I think this problem should be handled like blender does Ctrl+D to Duplicated Object (make a full duplicate of all objects recursively) and another Alt+D or Ctrl+Alt+D to Duplicate linked (what Godot does right now)

Manually creating (even using Ctrl+Shift+A) and selecting a scene each time is tedious

Thanks

A sub-issue due to this is if I assign the grass.gd script a class_name Grass and use the Make Sub-Resources Unique option in the inspector for those Ctrl+D'ed grasses to make them unique (as some threads on the internet suggest doing), the script is duplicated too (with the same class_name), and causes a global class-name overshadow error, right at the launch of the game. This will happen for any scripts using class_name

Therefore, this is not a solution

Just wanted to add that the same behavior is found when using Node.duplicate(all_flags) during runtime too. This becomes an issue when needing to duplicate area3d packed scenes. The duplicate returned by Node.duplicate() still shares collision shape resources in their collision shape child nodes.
