Delete Branch "guishe:improve-swap-strips"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Fixes a bug where disallows swap strips in certain cases:
and have 2 strips selected.
Why happens:
Currently to
swap strips
the code maketemp meta strips
, it checks if the first stripin the
nla track
is atemp meta strip
and if it has only2 strips
and if it does, it separates thistemp meta strip
back into the strips.This is one specific case that don't work well or all cases.
The solution:
The operator should allow to swap 2 strips or 2
temp meta strips
(clusters)To make this possible check how many
temp meta strips
(clusters) are selected,if they are only 2 try to swap them.
If they are 3
temp meta strips
(clusters) the swap should fail.If they are only one
temp meta strips
(clusters) break it into separatestrips
and check if there are only 2strips

NLA: Keep bounds on strips swap and fixesto NLA: Swap strips fixes@guishe You have both this and #109980 open for fixing #109081. Do you think one or the other is better? And can you elaborate on what the pros/cons of the two different fixes are?
Honestly I don't have much to say about #109980, because after using the shortcut and and see that it fail the user has to fix positions to be able to use the shortcut again.
This pr makes swap directly adjust the position of the strip that will be placed to the right if necessary, then the user can make necessary adjustments if needed. The only drawback is that the original position is not recovered after another swap, due to the necessary adjustment that was made in the first iteration (as seen in the video).
Got it. Thanks for the explanation! I'll add this to the animation & rigging module meeting agenda (this Thursday), to see which solution people prefer.

Separate the pr in 2 to better explain the issues separately: (see #110074 (comment))
The fix that i mention that was a alternative i will move it to another pr #109980
Thank you for your patience!
In the animation & rigging module meeting, we decided that #109980 is the most appropriate fix. I'll comment there with more details.
Closing in favor of #109980.
