NLA/Timeline Support
* Reshuffled code for existing "View Frame" implementations, and removed leftover
comment from some of the the copy-and-paste used to build it.
* Added support for this operator in the NLA and Timeline
|

To help make it more convenient to edit stashed actions, Shift-Tab
(i.e. holding down the Shift key, which "tabbing" into tweakmode as
usual to edit the action referenced by the active NLA strip) now flags
the NLA Track that the strip occupies as being "solo" too.
This allows you to use the NLA to select a stashed action, then Shift-Tab
to start editing it without any other actions in the NLA stack interfering.
Like the "Next/Previous Layer" tools in the Action Editor, this is designed
to help with checking on stashed actions.

(NLA buttons support to come)
After looking into this more carefully, I've found that we do in fact need a dedicate
operator to add some custom logic when trying to unlink an action from the editor/datablocks.
Specifically, this new operator does the following:
1) When in Tweak Mode, it shouldn't be possible to unlink the active action,
or else, everything turns to custard.
2) If the Action doesn't have any other users, the user should at least get
a warning that it is going to get lost.
3) We need a convenient way to exit Tweak Mode from the Action Editor
4) If none of the above apply, we can just unlink normally
This commit implements this for the Action Editor, with stubs for the NLA Editor too.
Those will be fixed next.

* If channel_index = -1, the pushdown operator will try to use the active AnimData
block. To see which one this will be, check the properties (NKEY) region in NLA Editor.
* Added more detailed error handling for the various cases where things are not
in a valid state for pushing down an action. This is notably to stop scripters
from putting the NLA into an inconsistent state.

This operator is used to make sure that if/when you have multiple strips
using the same action, if you select these and run this operator, each
strip will be given its own copy of the action. This is useful if you
decide later that you want to start using an existing action as a base.
NOTE: This does not recursively go inside meta's, so care is still advised
in that case.

selected strips
This brings it more in line with the other anim editors, and makes like a little
bit easier for animators working on games or looping anims.
|
|
|
|
tweakmode, this will now result in tweakmode being exited instead of going into
a weird limbo-land where channel selection has changed (but tweakmode is still
active but not drawn)
|
|
tracks
As a convenience feature for those who are loading in action libraries and using
these to quickly block out things in the NLA editor, it is now possible to add
strips to AnimData blocks without first manually creating empty tracks to add
these strips to. Simply ensure that such empty AnimData blocks are selected
(Hint: click on the action line of the affected AnimData block to do so), and
try to add a strip normally.
|
|
|
|
This commit introduces an operator in the Add menu - this operator ensures that
all selected objects have AnimData attached to them (even if they don't have any
actions/drivers yet). By doing this, these objects can at least appear in the
NLA Editor, which will allow them to have strips added to them in future without
having to create throwaway actions first (NOTE: there's still some stuff coming
to allow that).
Also, renamed NLA_OT_delete_tracks -> NLA_OT_tracks_delete

without the underscores these clogged up the namespace for autocompleation which was annoying.
|
|
* Some cleanup, removed references to already deleted *_header.c files.
* Marked SpaceScript as deprecated and removed header. Will keep space for now though, as some script operators are there and Campbell might want to re-use the space later.

These are basically just for specifying when a speaker should fire off
it's soundclip, and as such, many NLA operations are irrelevant for
it. They can only be specified on object-level for speaker objects.
I've still got some UI tweaks I'll need to work on in order for these
to be able to be added even when the speaker doesn't have any NLA
tracks yet. (EDIT: while typing this, I had an idea for how to do
this, but that'll be for next commit). In the mean time, you'll need
to add a single keyframe for the object, snowflake that action and
delete the NLA strip before you can start editing.

1) Added a new operator to swap the order of strips within a track
(Alt-F).
This makes it possible to select two strips (or more precisely, two
islands of consecutive + selected strips) in a single track and change
the order in which the appear without needing a extra tracks to
perform the move through.
As usual, the non-overlapping rules apply, so there may be some cases
where swapping in this way is not possible without adjusting the
intermediate strips first manually. Otherwise, everything just gets
too tricky to manage deciding what adjustments should be done to the
obstructing strips to make a fit.
2) Freeing meta-strips didn't free their local data properly (i.e.
modifiers they may have had).
3) Adding strips to tracks, where the endframes for the strips
overlapped would cause problems with incorrect ordering of strips. I
still need to double-check whether evaluation works ok in this case...

* Copy/Paste operators for F-Modifiers
Available in Graph and NLA Editors. Use the Copy/Paste buttons beside the 'Add Modifier' buttons.
Copy copies all the modifiers of the ACTIVE F-Curve or Strip depending on the editor.
Paste pastes modifiers from the buffer to all the selected F-Curves or Strips, adding the new modifiers to the ends of each list.
* 'Stepped Interpolation' F-Modifier
This modifier holds each interpolated value from the F-Curve for several frames without changing the timing.
This allows to preview motions 'on-twos' for example without altering the timing, or having to go through setting heaps of keyframes. In this case, Andy wanted to use this for CG <-> StopMo.
|
|
|
|
This operator can be accessed from the "Action Clip" panel, and is used to include keyframes that have been added to a strip already in the NLA. Although this is not a recommended workflow, having this ability is useful at times.

Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.

Now the mute/protect/expand/etc. toggles are drawn using UI widgets. This means that special event handling code to determine when they were clicked on is no longer needed, and also means that there can now be tooltips for these items too.
Also, added visibility toggles for ID-block expanders, which will cause all the F-Curves in the linked datablock to not get drawn. The backend filtering code to make this work will come later...
|
|
This operator provides a quick way of toggling the muted-status of several strips at the same time.
|
|
Recoded the Transform code for NLA-Strips so that they can now be moved between strips and will not get truncated when they get moved into other non-moving strips.
Todos:
* The current code for moving strips between tracks is buggy (only goes up, and has a tendency to move up without being told to)
* Auto-snapping doesn't work yet...
|
|
* Added several API functions for Meta-Strips editing. One of these (flush transform) still needs a few tweaks before it does its job well enough for all cases.
* Meta strips are now drawn with a purple-ish colour. The start/end points of the strips they encompass are shown with lines along the length of the strips, with lines starting from the top indicating start-points and lines starting from the bottom indicating end-points.
* Meta strips can be made (i.e. strips can be assigned to meta-strips) by selecting some strips and pressing Shift-G.
Meta strips can be removed by selecting some meta-strips and pressing Alt-G.
* Strips can now be 'snapped' to start from: the current frame, the nearest frame, the nearest second, or the nearest marker; using the Shift-S hotkey.
'Islands' of adjacent selected strips occurring in the same track are moved together as a single strip so that the start-point of the first strip is on the sepcified time, but all the relative lengths of strips stay the same. Internally, temporary meta-strips are created to facilitate this.
|
|
Refactored the backend code/API's to support 'meta' strips (i.e. strips containing other strips). These have been implemented to be nested to 'unlimited' depths (in terms of common usages that is, though there is a very remote chance of stack-overflow in theoretrical evil cases only that shouldn't ever be encountered in production).
This paves the way for implementing the necessary tweaks needed for the transform code (in addition to some cool user-level tricks)
|
|
* Using the Ctrl-Shift-M hotkey, F-Modifiers can be added to all the selected strips.
* F-Modifiers can also be added/tweaked from the NLA N-Key properties. The UI now uses the same code as for the graph editor ones.
The UI drawing here is currently messed up from the NLA side, since it seems combining normal layout stuff and old-style uiBlocks doesn't seem to work too well (BUT! the buttons are at least functional).
Next up, I'll need to recode the buttons panel for the Graph Editor so that all of the drawing can be migrated over to use the new layout engine.

These operators may be temporary only, depending on if a workable solution via transform is found.
* PageUp moves strips into the track above if there's space
* PageDown moves strips into the track below if there's space
* Also fixed a button-alignment bug in the DopeSheet header
|
|
These two operators work only on Action-Clip strips.
* Clear (Alt-S) resets the scale of selected strips to 1.0
* Apply (Ctrl-A) applies the scale of the selected strips to their referenced Actions. If this referenced Action is also used by several other strips, a copy of the Action is made, and the scaling is applied to that Action instead.
|
|
This deletes all the strips in the relevant (selected) tracks too.
|
|
* Clicking on NLA tracks while in TweakMode now works so that channels can be muted/protected/expanded as per usual. However, they cannot be selected, as changing the selection state can interfere with TweakMode state changes
* Operators for animation channel-lists now use proper poll callbacks, which also take into account TweakMode where appropriate (i.e. all selection operators are now allowed to operate in NLA while in TweakMode, and all other operators will only work in Animation Editors)
* Action Editor operators now use the poll callback for Action Editors/DopeSheet instead of the generic active-araa one.
|
|
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...
|
|
== 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

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
