-Fixes to unwrapper (remove degenerates), makes Thekla not crash
-Added optional cancel button in EditorProgress
-Added function to force processing of events (needed for cancel button)
That happened when an instanced scene was being duplicated while it also contained nodes added to it in the scene holding the instance.
Plus:
- Add comments about the logic behind all this.
- Move the null guard to where it can protect the most, but consider it a runtime error rather that a situation we expect.
Fixes#13282.
- Partially revert 6496b53549, adding a comment about why duplications of signals must happen as a second phase.
- Add fallback logic for connections to nodes not in the duplicated hierarchy.
- Remove redundant call to `Node::_duplicate_signals()`.
Fixes#12951.
Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:
* pos -> position
* rot -> rotation
* loc -> location
C++ variables are left as is.
When duplicating node with script, properties of script
weren't copied sometimes.
It happened because properties were copied in arbitrary
order, and properties of the script were setted before the
"script" property itself, i.e. while script is sill NULL.
Also, DUPLICATE_SCRIPTS flag wasn't working - script was
always copied because `_duplicate` looked for
"script/script" property while it should be just "script".
Now "script" property is being set before all others,
and "script/script" changed to
`CoreStringNames::get_singleton()->_script`.
Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.
This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.
It is explained in this article: https://www.viva64.com/en/b/0226/
It is possible to propagate a notification down the Node tree by
using `propagate_notification`, but there was no such method for
doing the same but with method calls.
This commit adds the `propagate_call` method, which calls a method
on a node and all child nodes. An optional paramter `parent_first`
determines whether the parent node gets called before or after the
children have been visited. It defaults to false, so the parent
gets called last.
Thereby, the editor will acknowledge node namings such as _Thing003_ so that a duplicate, for instance, will be named _Thing004_, instead of _Thing4_, that was the case formerly.
Closes#7758.
This avoids the display folded flag needlessly getting into the scene file (potentially forever) and also gives more visual feedback if the user re-enables editable children so it will display unfolded at first.
