* Removed nAction struct. We'll be using good ol' bAction structs again, but putting new data in a different list. Apart from that, the data is similar enough to do so.
* Rearranged code in DNA_action_types.h while renaming the structs to avoid confusion over what is currently in use...
* Added freeing and AnimData execution loops for many other ID-types too. (NOTE: I've added AnimData in NodeTree struct too, but it's not clear to me where the relevant data-management calls should go in Nodes code).
* File writing code should now only write the new data to files
* Made AnimData blocks be stored as pointer instead of directly in the ID-datablock, so that fewer files will need to be recompiled everytime some animation settings change.
* Tried to fix some of the compiler errors that pop up in Yafray code. If this commit doesn't fix it, just disable Yafray code for now (WITH_BF_YAFRAY=0 for scons)...
Finally, here is the basic (functional) prototype of the new animation system which will allow for the infamous "everything is animatable", and which also addresses several of the more serious shortcomings of the old system. Unfortunately, this will break old animation files (especially right now, as I haven't written the version patching code yet), however, this is for the future.
Highlights of the new system:
* Scrapped IPO-Curves/IPO/(Action+Constraint-Channels)/Action system, and replaced it with F-Curve/Action.
- F-Curves (animators from other packages will feel at home with this name) replace IPO-Curves.
- The 'new' Actions, act as the containers for F-Curves, so that they can be reused. They are therefore more akin to the old 'IPO' blocks, except they do not have the blocktype restriction, so you can store materials/texture/geometry F-Curves in the same Action as Object transforms, etc.
* F-Curves use RNA-paths for Data Access, hence allowing "every" (where sensible/editable that is) user-accessible setting from RNA to be animated.
* Drivers are no longer mixed with Animation Data, so rigs will not be that easily broken and several dependency problems can be eliminated. (NOTE: drivers haven't been hooked up yet, but the code is in place)
* F-Curve modifier system allows useful 'large-scale' manipulation of F-Curve values, including (I've only included implemented ones here): envelope deform (similar to lattices to allow broad-scale reshaping of curves), curve generator (polynomial or py-expression), cycles (replacing the old cyclic extrapolation modes, giving more control over this). (NOTE: currently this cannot be tested, as there's not access to them, but the code is all in place)
* NLA system with 'tracks' (i.e. layers), and multiple strips per track. (NOTE: NLA system is not yet functional, as it's only partially coded still)
There are more nice things that I will be preparing some nice docs for soon, but for now, check for more details:
http://lists.blender.org/pipermail/bf-taskforce25/2009-January/000260.html
So, what currently works:
* I've implemented two basic operators for the 3D-view only to Insert and Delete Keyframes. These are tempolary ones only that will be replaced in due course with 'proper' code.
* Object Loc/Rot/Scale can be keyframed. Also, the colour of the 'active' material (Note: this should really be for nth material instead, but that doesn't work yet in RNA) can also be keyframed into the same datablock.
* Standard animation refresh (i.e. animation resulting from NLA and Action evaluation) is now done completely separate from drivers before anything else is done after a frame change. Drivers are handled after this in a separate pass, as dictated by depsgraph flags, etc.
Notes:
* Drivers haven't been hooked up yet
* Only objects and data directly linked to objects can be animated.
* Depsgraph will need further tweaks. Currently, I've only made sure that it will update some things in the most basic cases (i.e. frame change).
* Animation Editors are currently broken (in terms of editing stuff). This will be my next target (priority to get Dopesheet working first, then F-Curve editor - i.e. old IPO Editor)
* I've had to put in large chunks of XXX sandboxing for old animation system code all around the place. This will be cleaned up in due course, as some places need special review.
In particular, the particles and sequencer code have far too many manual calls to calculate + flush animation info, which is really bad (this is a 'please explain yourselves' call to Physics coders!).
* Added more compact property definitions, with a single function.
Only used by operators at the moment, would need to tweak regular
expressions a bit more to use it also for other RNA definitions.
* The operator properties defined now were completed a bit more but
still have many issues that need to be adressed, specifically;
* Some properties that should be booleans or enums are defined as
ints, note that ints are only for numeric values, not bitflags
or multiple choice.
* Soft/hard limits and default values of many properties are not
well defined still,
* Inconsistent naming, especially for example mouse locations or
bounds are named differently in different places. Also mouse
locations and other vector like properties should become a single
vector property instead of multiple X/Y properties.
* Almost no properties have descriptions, these would be good to
have for docs and tooltips.
So, please verify that the properties of the operators you wrote are
well defined.
- Weightpaint back (CTRL+TAB or menu)
Also weightpaint is sortof non-modal, allowing to use all existing
hotkeys while in paint mode. Only leftmouse is overridden.
- Made vpaint and wpaint entirely local, stored in scene (and saved!)
- Small bugfix (also in 2.48): on weightpaint mode, all armature objects
in 3d window were drawing as active poses. Now only the armature
deformer is.
Nice point for the UI agenda: are paint modes on ACTION mouse? Only then
you can combine it with SELECT mouse...
* Added crash fixes for loading old files with Actions/Armatures in them. Was caused by usage of some old globals still and the functions in question not performing NULL checks on the validity of the data they're given.
* Added back reorganise action channels tools (shift/ctrl-shif pageup/down) for Action Editor. These are only available in 'Action Mode' only.
* Tidied up Action Editor/Dopesheet tools code - removed various unused things, and also, added an API call in anim_deps.c to send the correct notifiers, since I anticipate that they're likely to require a few context checks which would be better to centralise than copy+paste everywhere.
Note to Ton: could you have a look at this notifier stuff here? I'm not sure which ones I should be sending...
* Also added a few assorted comments in various places
* Animation channels - cleaned up the code for selecting channels (removed various TODO stuff that's going to be replaced by something better later). Also, added back the ctrl-shift select feature for groups, which should be extended for other channels too at some stage.
* Outliner - added missing flags to do-versions, and replaced the width calculations with the rna-width version for now, as that uses constant width of 100 with OL_X*indention
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
* Start of Action/Pose syncing code (in anim_deps.c) This is currently not hooked up yet, as we still need to figure out where these should get called (due to a few dependencies they have - i.e. visibility syncing of channels is turned on/off by setting in appropriate views).
* Also added assorted comments/changes to rna/dna
* Added the relevant filtering necessary for this to work, into the animation-channel filtering code.
* Updated most of the keyframe-editing tools to respect this
* Renamed keyframe-editing API loopers (added ANIM_ prefix) for consistency
* Added function for mapping keyframes to/from NLA-mapping for Ipo-Curves in addition to the one for IPO blocks. As a result, renamed the latter for consistency.
* Added back enable (Ctrl-Shift-W), disable (Alt-W), and toggle (Shift-W) operators to channels view. They are separate operators which use the same backend code.
* Fixed icon-drawing for IPO-curve 'protect' buttons. After doing this, I've realised that many tools will need some alterations to take this into account. That commit will come later.
* Added back deselect all (and invert all) tools for Animation Channels (i.e. channel list in Action Editor).
* Resolved all MSVC warnings (I came across) in View2d code. Also, added a new API method to get the coordinates (in 'view' space) of a listview 'cell' given the row + column the cell is in.
* Tidied up a few comments here and there
- Put back vertex/edge/face select
- Mode menu allows going in/out editmode
- Tested some tweak event stuff in WM, made tweak event follow
user preset for 'action' or 'select' mouse.
(Wanted to try this for transform, but better get advise from
Martin first :)
* Dopesheet - clicking on keyframes in Object channels (if they came from Object-Data such as Lamps, etc.) would crash. I noticed this error in AnimSys2 yesterday
* Action Editor - do versions code now totally reinitialises the Action Editor View2D data (for the timespace), since I found a few files where there appeared to be some weird settings set.
* RNA Browser (Outliner->Datablocks) would crash when the Area was ripped (using Alt-R hotkey) as seen in mfoxdogg's 2.5 Tour 2
* Fixed 'mute' icons for IPO-Curve channels. Added define for icon-button widths instead of magic numbers there too.
* Restored View All (HomeKey) and Auto-Set Preview Range (Ctrl-Alt-P). These tools both use the max extents of the keyframes to determine their (time)range.
First commit for 2009!
Started of porting of Animation Editor Channels stuff.
This code will be used for both the Action and IPO editors, so any existing code involving this has now been moved to the Animation module.
* Added mouse-click operator for this channels view. Note: the selection stuff currently uses temporary toggling code only (i.e. it only toggles the selection of the channels in the editor, but does not update status of rest of database).
* Fixed bugs in View2D listview functions. Reduced the amount of code needed, and makes the code here simpler.
* Renamed action_edit_keyframes.c to action_edit.c, since channels are not handled there anymore.
* Dopesheet now refreshes correctly when object selection elsewhere changes.
Note: there were some crashes that would occur if context was not reset everytime the modal callback was run. Probably there's something about the context info we need to be more careful about.
* Brought back clean (OKEY), sample (Shift-OKEY), and delete (XKEY/DELKEY) tools for the Action Editor.
Currently clean uses a predefined threshold (as a rna-prop, though it's still lacking the popup to set this when it is called)
* Added new file for 'destructive' keyframe operations/tools.
* Got keyframing.c compiling. Now, some of these tools need to be operatorised. Also, the API there might change when enough of the system is stable for RNA-IPO work to take place (so that it can be tested).
* Added 'set handle-type' operator. Currently, all possible handle types are all set using a menu and HKEY. This will need to be reviewed at some point, but I think it should be easier for users to remember 1 hotkey for this, rather than 4 scattered around the place.
* Added 'set interpolation' operator. This uses the Shift-T hotkey as before (for now). As in AnimSys2, this sets per-keyframe interpolation.
* Remapped toggle frames/time-codes operator to Ctrl-T key. This may still change, but the TKEY needs to be free for transform tool here.
Anim playback part 1 (needs more test, will do after commit)
- added the update_for_new_frame() back
- proper evaluation of time change notifier in WM level
- fixed redraw flushes for menus while animation plays.
Notifier system upgrade, based on Brecht's doc.
Implementation notes:
http://wiki.blender.org/index.php/BlenderDev/Blender2.5/DataNotifiers#Implementation
In short: let's try to strictly communicate in a notifier what happened.
The listeners then can act themselves. It also means that a frame-changed
notifier doesn't send out redraws, the editors themselves can decide.
* Started porting back keyframe editing tools for the Action Editor/Dopesheet. Currently, only Snap (Shift-S) and Mirror (Shift-M) are functional.
* Added keyframe-editing API method for ensuring that all IPO-curves are left in a valid state after modifiying the values of their keyframes.
* Added operator-register flags for most of the operators. Only mouse-select doesn't have it for now (as there's not much useful info stored, and no exec callback).
User Notes (for using tools whose behaviour has changed):
* Mouse Selection Tools:
1) Click on keyframe to modify its selection. Holding the 'Shift' modifier when doing so, will result in keyframe selection being toggled instead of replacing existing selections.
2) Click on either side of the current frame indicator while holding the 'Alt' modifier. This will select only all the keyframes on the relevant side of the current frame indicator.
3) Click on a keyframe while holding the 'Ctrl' modifier. This will select all the keyframes that fall on that frame.
* Borderselect Tools
1) BKEY selects all the keyframes within the specified range (as per normal)
2) ALT-BKEY will select either all the keyframes in the frame-range specified or the channel range specified, depending on which axis of the select region was larger. This method is prejudiced towards frame-range selection.
Code Notes:
* Finished porting over all of the remaining keyframe selection tools, and recoded the ported ones to make them easier to use (after running into some technical limitations)
* Simplified the way to check if 'animation context' is valid by moving a necessary check into that function.
* Refactored internal keyframe-looping tools to reduce the amount of code needed per tool to edit keyframes, removing a lot of the unnecessary bulk. Now, the ipo/icu_keys_bezier_loop functions recieve a few more arguments (1st arg is pointer to generic customdata, and another defines a validation callback which makes it easier to reuse some of the select callbacks).
* Added 'totrect' adjustment for number of channels being shown in Action Editor, so that scrolling will be limited to where there is data (and also so that scroller displays more relevant context info).
For this to work, filtering channels now returns the number of channels extracted. This may come into use for other tools if there's such a need.
* I still need to port over some code for markers, which is required for some of the tools which use them. For now, those tools do nothing.
* Grease-Pencil editing mode in Action Editor is currently non-functional (code is commented out due to missing dependencies). This is currently pending the re-implementation of Grease Pencil in 2.5
Ported the following tools
* borderselect
* invert selection
Note: while porting these, I noticed a few issues with some stuff that still needs to be cleaned up.
Events handling in scrollers won't work yet, for the useful select all in frame(-range) or select all in channel(s). We should probably review ways to expose this more clearly in the UI too.
Object: converted the old horrible editobject.c, now as file:
editors/object/object_edit.c
Still lots of WIP, I've operatorified "Make Parent". Check here
the new API at work: http://pasteall.org/3650/c
IMPORTANT NOTE FOR BRECHT:
game property defines were clashing with RNA, i've renamed game
defines for now.
It is now possible to select individual keyframes again in the Action Editor.
* Temporarily disabled markers keymap in Action Editor, as it was stealing all the events. Waiting for solution from Ton...
* Fixed a crash and wrong coordinate conversion errors
* Brought back backend for editing keyframes IPO/IPO-Curves. Did some refactoring work here that will still have to be verified when operators using them are added.
* Animation channel filtering code now returns the number of channels filtered (for Action Editor to set totrect of channels - TODO still!)
* View2D - made function to check if mouse is in View2D scrollers an API function
* Renamed keyframe related files. The old names were too clumsy.
* Started porting click-select operators for Action Editor. These don't work currently, as the events are being stolen by the markers. This needs to be fixed ASAP.
* Action Editor - IPO curve names are shown properly again. Added anim_ipo_utils.c (old editipo_lib.c) file back. This will need to be removed when I port IPO system to RNA.
* Keyframing code - uncommented more of the code that's now working
* Made the 'preview range' button on timeline header draw more clearly
* Restored y-position translations needed for gla-stuff, as gla stuff sets viewport + matrices!
* Fixed alpha-problems with icons. The ft-font drawing was turning off GL_BLEND when it was done, which screwed up the icon drawing (previous names were drawn with 'standard' fonts only)
* Removed Context arg from drawing funcs. Passing anim-context instead.
* Properly initialised new theme settings ported over from animsys2.
Cleanup
- for portablity we can keep the old ugly defines for retrieving
active object, cfra and so on. But, they will use 'scene' not
G.scene.
- fixed code that uses those defines.
- some unused variables/functions removed
Initial commit of drawing code for Action Editor / Dopesheet. By default, the Dopesheet is now enabled (like in AnimSys2). There are still a few unresolved problems (like bad alpha blending for icons, and keyframes still not being drawn). However, these will be resolved in due course.
* Re-exposed relevant parts of anim_keyframing.c code that doesn't have external dependencies.
* Added get_active_posechannel() to blenkernel api for poses/posechannels to solve the only missing link I found. This should have been moved there ages ago!
Moved time_ops.c contents to anim_ops.c, as the operators there are applicable to all other Animation Editors too. anim_ops.c will therefore contain all operators which will apply to all Animation Editors (i.e. change frame, frames/seconds display toggle, and soon Preview Range tools).
As such, added new global 'Animation' keymap like for View2D and Markers, which will ensure that these tools can be accessed in an uniform way across editors.
Note that the order that these things are added is important, as the Animation ones will often 'steal' events from the View2D and Markers ones if placed before the others. To prevent that, we'd need to be able to set boundboxes here...
Brought back the Filtering API for Animation Editors. This is the 'backbone' of the current Action/Dopesheet Editor code, so it is essential to have this working.
* Fixed current frame number drawing in Animation Editors, so that the little frame number indicator box gets shown (animsys2 feature).
* Made all Animation Editors draw markers and preview range
