Drivers can use this to refer to the data which the driver is applied to,
useful for objects, bones, to avoid having to create a variable pointing to its self.
The "W" channel will get a yellowish colour (i.e. a blend between the X/R and
Y/G axis colours), while the XYZ will behave as they do for other transforms.
Sometimes the autokeying flags don't get set correctly (i.e. the "mode" flags
used for 'Add + Replace' vs 'Replace Only' aren't set), meaning that the old logic
would always fall through to the "replace only" case. When this happens, the resulting
behaviour can be quite strange and hard to debug. This fix prevents problems like
this from continuing to be an issue...
Now, when trying to insert a keyframe on a driven property (using IKEY, or with
autokeying enabled), the keyframes will get created on the Driver's F-Curve
(instead of creating a new FCurve that goes into the active action, but will never
do anything). Furthermore, the x-value of the new keyframe will be the current
result of the driver expression.
Why/Motivations:
This way, it becomes easier to create corrective drivers, as you can position all
the targets the driver depends on, then adjust the driver value until it does what
you need, and then you keyframe that value to bake it into the Driver F-Curve
(in effect, "training" the computer how to behave in that case).
Usage Notes:
* In practice, that particular workflow is still quite clunky to achieve, due to some
quirks of how the driver system and the UI widgets interact. Specifically, you'll
need to disable/mute the driver before trying to edit the setting (to prevent the
driver from immediately resetting the value - before even autokey fires!). However,
if you're using the Graph Editor to preview/monitor/manage the keying process, you'll
then want to re-enable the driver before changing the targets, so that you can see
how much of a change you'll want to be applying!
* The warning about editing driver values may need to be disabled or selectively
knocked out. I had it disabled while testing this functionality, but it's actually
harmless in its current state (if just a bit annoying).
To make it easier for animators working in a multipass pose-to-pose workflow
when inserting breakdown keyframes and so forth, it is now possible to specify
the "type" of keyframe being created (i.e. the colour of the keyframe, when drawn
in the Dope Sheet).
Usage:
1) Choose the type of keyframe ("Keyframe", "Breakdown", "Extreme", etc.) from
the new dropdown located between the AutoKeying and KeyingSet widgets on the
timeline header.
2) Insert keyframes
3) Rejoyce that your newly created keyframes have now been coloured for you already
in the DopeSheet.
Todo:
* Look into a way of using the actual keyframe colours (from the theme) for the icons
of these types.
Debug print here is not that useful to common user, and keyframe deletion
does report warning, so do the same for clear op.
Reported by venomgfx over IRC, thanks.
Technically this was more of a feature request, but now the Alt-I operator will
only remove keyframes related to selected bones in Pose Mode. In Object Mode,
it will continue to operate on all keyframes of the object.
This change makes this operator more meaningful when animating in the 3D view.
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
This calls are not strictly speaking needed for the old dependency graph, but
due to more granular nature of upcoming depsgraph more actions requires update
of relations of IDs.
On the one hand this extra tags could be wrapped with if() statements, but on
the other hand it makes sense to keep tag in sync so it's clear if some issue
is caused by missing/extra tag or by depsgraph itself.
As a followup for the previous commit, do the same thing for the insert/delete
keyframe button operators as is done for the clear keyframes op. There really isn't
much need/reason for conducting the looping there, as those functions natively
handle this themselves already.
On second thought, the previous commit was just adding additional complexity which
wasn't needed, as the operator was wasting effort by doing this looping itself.
This commit implements proper evaluation + keyframing support for animating influence
and time on NLA Strips (among other properties) by resolving a few long standing issues
which prevented the original design for this from working.
The original design for animating these properties (and/or some of the other settings
on NLA Strips) is that NLA Strips actually have some of their own F-Curves that are
used for animating settings which will affect how they are evaluated. As seen in this
bug report, the alternative of having these animated as part of the stack (which the
strips work above/outside/on-top of) means that glitches can occur.
Although one of the original considerations for why this wasn't implemented earlier
was that introducing keyframes there isn't so clean cut, and causes UI design issues
for how we expose these via the animation editors for editing (NOTE: support for that
is still to come). Another concern is that this sets a precedent for how FModifiers
might get evaluated.
When the active action is a NLA strip, the keyframe indicator colors for buttons
and the 3D view indicator (i.e. the current frame indicator changes color) didn't
work correctly. This was because they were still checking for keyframes in
"global" time space, whereas they needed to be applying NLA corrections to
"look inside" the remapped action.
Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
Operators that trigger UI events (but nothing else)
were using 'CANCELLED' making it impossible to tell if an invoke
function failed, or opened a menu.
Added an extra option to `insert_bezt_fcurve()`, to allow full override of existing
keyframes when pasting (in this case, we do not want to inherit handles from existing
curve!).
** TO BE PORTED BACK TO 2.71 **
As pointed out by Thomas Beck (plasmasolutions), the current behaviour and/or
default values for their parameters didn't quite make sense:
1) Back Easing - The old default value of 0.0 results in some overshoot being applied,
while trying to tweak it up or down resulted in some odd jumps and discontinities.
I've ended up removing some code here which forcibly using a "back" value of 1.7
when users wanted 0.0 instead. There doesn't seem to be any good reason for this.
To ensure that there is still an effect initially, keyframes now get created
with back set to 1.7
2) Elastic Easing - The old default settings of <amplitude = 0, period = 0> resulted
in a curve without any elastic bounce, which wasn't very useful for motion graphics.
Now, default values of amplitude = 0.8 and period = 4.1 get set. These were hand picked
by Thomas to work well when the duration of the motion is 10 frames long (i.e. the
typical length of such effects when doing motion graphics).
When the dopesheet was open, "keyframe edited" events from the graph editor
(i.e. fired whenever any properties on keyframes or FModifiers are changed)
would trigger the dopesheet to synchronise selection states of anim channels
and ensure that FCurve autocolours are initialised correctly.
This however was undesired when editing properties in the graph editor. Now,
made it so that keyframe adding/removing operators use different notifier flags
to specify that the channels might have changed + need colour syncing, and
adjusted the dopesheet updating logic to fit
libraries view not working.
This was disabled in the operator, there may have been a reason for this at
some point, but I can't see any reason to disallow it in the current code or
find a good reason why it was done in the commit logs.
