It is now possible to Duplicate Strips again. Strips are added into the first available space in the track above the original track (or a new track above the original if there wasn't any space).
Also, separated out the 'add' operators into their own menu. This might need to be changed later...
When an F-Curve doesn't contain any keyframes anymore but it still exists, the F-Curve's value is not recalculated and flushed anymore if the F-Curve's value will not change. That is, if the F-Curve doesn't have any other data, i.e. drivers or generator-modifiers, which would still change its value, it wouldn't be recalculated to have a value of zero.
This solves the problem of deleting all scale keyframes, whereby objects/bones would appear to 'vanish'
== Transitions ==
Transition strips are now able to be created + evaluated. Transitions allow for interpolation between the endpoints of two adjacent strips in the same track (i.e. two strips which occur in the same track one after the other, but with a gap between them).
- The current behaviour when only one endpoint affects some setting is non-optimal, since it appears somewhat inconsistently extend/replace values...
- Transform code needs a few fixes still to deal with these
== Strip Adding Operators ==
* New strips referencing Actions can be added using the Shift-A hotkey while in the strips-area. You must have a track selected first though.
The new strip will get added, starting from the current frame, in the selected track(s) only if there is enough space to do so. Otherwise, the new strip gets added at the top of the stack in a new track.
* New transition strips can be added with the Shift-T hotkey while in the strips area. You must have two adjacent strips selected for this to work.
== New Backend Methods ==
* Recoded the strip/track adding API to be more flexible
* Added a new method for testing whether F-Curve has any modifiers of with certain attributes. Will be used in a later bugfix...
== Bugfixes ==
- Fixed bug with strip-blending which caused the blending modes to be useless.
- NLA buttons now use proper poll callbacks instead of defining checks
- Commented out missing operator in menus, silencing warnings in console
- Removed obsolete/incorrect comments
- Lower bound for start values has been expanded to -MAXFRAME, to avoid clipping problems when the strip is moved past frame 0
- Removed some obsolete (+ commented out) NLA wrapping in Object stuff
In response to user-feedback, I've changed the order in which channels appear. Now, the channel ordering is:
- Object/AnimData block
-- Active Action
-- Last NLA Track
..
..
-- First NLA Track
It is important to note several things still:
1) Active action is applied AFTER the NLA Tracks have been evaluated, not before
2) In this new order, the tracks+active action are shown in the evaluation-stack order, i.e. first thing applied is at the bottom, last is at the top.
As a result, I've switched the view-orientation back so that it works the same way as for DopeSheet/Graph editors (i.e. expands downwards not upwards). This may cause problems loading files saved with older builds of this branch. There are still some lingering problems due to this change which I'll fix in due course.
New tracks can be added in the following ways (with the mouse hovering over the channels-list):
* Shift-A - this will add a new track at the top of the stack (i.e. above all the existing NLA-tracks but below the Active Action) for every AnimData block where there was a selected NLA-Track
* Ctrl-Shift-A - this will add a new track above every selected one
Selected NLA Strips are split into two strips, each with half the length of the original strip.
Possible improvements subject to demand:
- multiple splits?
- splits with variable spacing? (i.e. 3:2, or 1:5).
* Strip scaling was being evaluated in the wrong way, resulting in scaled strips not being played too fast (for lengthened strips) or too slow (shortened strips)
* Also, verified that the 'reversed' option works correctly (no changes needed to be made here)
For fun, added 'sinc' (i.e. y = sin(pi*x)/(pi*x)) as a type of builtin function usable through the generator modifier. This makes a nice 'jolt' which tapers off.

(sheesh, that took an hour, not including having to restart the whole process after TortoiseSVN bailed out midway through the first try)
This commit restores transform support for NLA. Grab, scale, 'extend', and tweak (i.e. grab by just click+dragging) are implemented.
Notes:
- As soon as one end of a strip touches another adjacent strip (within the same track), that end stops moving. This has been done to avoid the situation where overlapping strips within the same track (which is not allowed) might be caused by transforms.
- Made some changes to the RNA setters for the strip extents so that the validation above could take place (and other necessary changes on a per-strip basis could also occur).
TODO's ?
- Strips cannot be transferred from track to track using transforms. I've yet to decide whether this needs to be done, or whether a separate operator will suffice.
- What happens to the range of Actions used when the strips change sizes unexpectedly (i.e. the no-overlap condition above)? Currently range stays the same, but this doesn't always seem desirable?
eg, layout.operator_context = 'INVOKE_REGION_WIN'
Needed to set the context that menu item operators are executed in.
fixed missing NULL check with anim system debug printing.
- clamp the border to the region bounds when selecting files
- fix for border select past the end of the filelist selecting nothing.
- de-selecting files would still set the filename.
- uiItemEnumO_string, forgot to actually set the enum value
- added more sequencer header buttons (these should probably be moved to a view panel eventually)
- Most of the settings wrapped in RNA have been exposed here using the new layout engine stuff from Brecht (C-API). I've tried to maintain a hierarchy of high-level (owner, generic-settings) to low-level (children, specialised-settings) here, which seems to be the prevailing guidelines?
(It took a while to try to understand how this all fitted together, since there were no clear examples on how to use this anywhere)
- NLA-Strip Modifiers have not been exposed yet. They still use the old-style drawing, which may/may not be compatible here.
- Fixed a bug with how the notifiers from this panel get sent. I really don't know how the compiler would have missed the undeclared pointer that was being used ('ob').
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
- Move buttons into the sequencer Nkey region
- Made the header and menu items use the python api, still need to get more buttons working.
- Fixed some minor problems
Small fixes:
- Preview render now accepts resize of 1 pixel without re-render,
solves re-renders on scrolling window or dragging panel, because
of float rounding.
- Panel dragging outline was off 0.5 pixel, showed as fat AA lines
- On switching tab, the preview gets re-rendered
Down with smart, up with simple!
I now use the widget polygon code to generate a mask quad strip,
draw it over the image, and then the AA outline. Should work on
all systems.
Removed masking idea for preview draw, it appears Win32 && X11 windows
are 24 bits, not 32 bits with alpha. Not going to open that can of worm
to add this, will find a different masking method...
Preview renders:
- Added proper button type (BUT_EXTRA) for preview buttons, to
handle drawing better. It now first draws an alpha mask, to
ensure the preview is correctly fitting inside the widget style.
It then draws the outline.
- Added protection for executing preview renders while regular
rendering, that's not going to work...
When an Animation Editor is showing timing in 'seconds' (instead of frames), the indicator label is now drawn with the same style of timecodes as the scrollbar labels are.
Attempt to make multires updating a little cleaner by
assuming that no update needs to be performed, and only
doing the update when the modified flag is set (either
by sculpting or using some other tool that needs an update.)
Example sequencer menu
self.layout.column()
self.layout.item_enumO("SEQUENCER_OT_effect_strip_add", property='type', value='ADD', text="Effect Strip (Add)")
* Context now allows pinning a datablock, independent of
selection.
* Initial ID browse buttons for most buttons tabs.
* Browsing from world to texture now displays world textures
again, but is a bit of a hack, not sure there is a right
way to do this.
* There's a button to switch between active materials and
textures now, only temporary though.
* There's some code to put context part in own region,
disabled still because it doesn't work that well yet.
* layout.split() now takes a percentage argument to control
the split position.
* ID template now works for more than just the Text ID type,
includes and icon, and some other fixes.
