Multiple selection support #301

Closed feiss closed 5 years ago

feiss commented 8 years ago

Multiple selection is a complex issue, but it could be simplified and limited to basic operations like transforms and simple edits:

S= list of current selected objects

If user LMB on empty space, S=[ ]
If user LMB on an item, S= [item]
If user ctrl+LMB on an item that is not selected, it adds the item to S
If user ctrl+LMB on a selected item, it removes from the item from S
ctrl+a selects all objects in the scene

If more than one object is selected:

The center of transformation (the helper axis) is in the average position of all the selected objects, and all transforms (translation/rotation/scale) are relative to that position.
No data is shown on the inspector panel (panel on the right), just "Multiple selection"
Copy/paste/duplicate/delete/scenegraph operations affect all selected objects

I wonder if we'd think about this differently if we framed this tool as complementary to code rather than a end-to-end tool. If so, then we could prescribe developers group their entities if they want to do a batch transform. This is a good prescription because if we are trying to do the same transform operations to multiple entities, then they probably belong in a group in code.

<!-- Grouping in code. -->
<a-entity position="5 0 0">
  <a-box></a-box>
  <a-box></a-box>
  <a-box></a-box>
</a-entity>

vs:

<-- Output of multi-select and applying individually. -->
<a-box position="5 0 0"></a-box>
<a-box position="5 0 0"></a-box>
<a-box position="5 0 0"></a-box>

FWIW, with Chrome's Developer Tools, you can pretty sloppily copy and paste anything from the Styles inspector and the resulting clipboard output is correct. Can we do something similar?

best practice to group entities?

feiss commented 5 years ago

Multiple selection and grouping are different things, you may want to modify multiple entities (ie. Moving the same distance) that are completely unrelated among them..

But it's ok, I didn't miss this feature much.

"It's ok" as in "yeah ok, we can live without this --although any serious app have this feature" :oD
