from Luca Bonavita (mindrones)
- adds the method "rebuildProxy()" useful to rebuild all the strips at once: the user can do
- adds a BlendModes dictionary under the Blender.Scene.Sequence module: the user can see the blending option with
- adds the getter/setter "blendMode"
- adds a function seq_can_blend in sequence.c as requested by Peter, useful for these purposes but also to solve a bug
after
- the bug is you can apply blend modes to an audio strip that doesn't make sense: changed the test and now you cannot
assign blend mode other than Replace to audio strips
Omitted DNA cleanup part since its only whitespace and Id prefer to have a useful "svn blame" output.
This patch introduces a simple state engine system with the logic bricks. This system features full
backward compatibility, multiple active states, multiple state transitions, automatic disabling of
sensor and actuators, full GUI support and selective display of sensors and actuators.
Note: Python API is available but not documented yet. It will be added asap.
State internals
===============
The state system is object based. The current state mask is stored in the object as a 32 bit value;
each bit set in the mask is an active state. The controllers have a state mask too but only one bit
can be set: a controller belongs to a single state. The game engine will only execute controllers
that belong to active states. Sensors and actuators don't have a state mask but are effectively
attached to states via their links to the controllers. Sensors and actuators can be connected to more
than one state. When a controller becomes inactive because of a state change, its links to sensors
and actuators are temporarily broken (until the state becomes active again). If an actuator gets isolated,
i.e all the links to controllers are broken, it is automatically disabled. If a sensor gets isolated,
the game engine will stop calling it to save CPU. It will also reset the sensor internal state so that
it can react as if the game just started when it gets reconnected to an active controller. For example,
an Always sensor in no pulse mode that is connected to a single state (i.e connected to one or more
controllers of a single state) will generate a pulse each time the state becomes active. This feature is
not available on all sensors, see the notes below.
GUI
===
This system system is fully configurable through the GUI: the object state mask is visible under the
object bar in the controller's colum as an array of buttons just like the 3D view layer mask.
Click on a state bit to only display the controllers of that state. You can select more than one state
with SHIFT-click. The All button sets all the bits so that you can see all the controllers of the object.
The Ini button sets the state mask back to the object default state. You can change the default state
of object by first selecting the desired state mask and storing using the menu under the State button.
If you define a default state mask, it will be loaded into the object state make when you load the blend
file or when you run the game under the blenderplayer. However, when you run the game under Blender,
the current selected state mask will be used as the startup state for the object. This allows you to test
specific state during the game design.
The controller display the state they belong to with a new button in the controller header. When you add
a new controller, it is added by default in the lowest enabled state. You can change the controller state
by clicking on the button and selecting another state. If more than one state is enabled in the object
state mask, controllers are grouped by state for more readibility.
The new Sta button in the sensor and actuator column header allows you to display only the sensors and
actuators that are linked to visible controllers.
A new state actuator is available to modify the state during the game. It defines a bit mask and
the operation to apply on the current object state mask:
Cpy: the bit mask is copied to the object state mask.
Add: the bits that set in the bit mask will be turned on in the object state mask.
Sub: the bits that set in the bit mask will be turned off in the object state mask.
Inv: the bits that set in the bit mask will be inverted in the objecyy state mask.
Notes
=====
- Although states have no name, a simply convention consists in using the name of the first controller
of the state as the state name. The GUI will support that convention by displaying as a hint the name
of the first controller of the state when you move the mouse over a state bit of the object state mask
or of the state actuator bit mask.
- Each object has a state mask and each object can have a state engine but if several objects are
part of a logical group, it is recommended to put the state engine only in the main object and to
link the controllers of that object to the sensors and actuators of the different objects.
- When loading an old blend file, the state mask of all objects and controllers are initialized to 1
so that all the controllers belong to this single state. This ensures backward compatibility with
existing game.
- When the state actuator is activated at the same time as other actuators, these actuators are
guaranteed to execute before being eventually disabled due to the state change. This is useful for
example to send a message or update a property at the time of changing the state.
- Sensors that depend on underlying resource won't reset fully when they are isolated. By the time they
are acticated again, they will behave as follow:
* keyboard sensor: keys already pressed won't be detected. The keyboard sensor is only sensitive
to new key press.
* collision sensor: objects already colliding won't be detected. Only new collisions are
detected.
* near and radar sensor: same as collision sensor.
patch from Shawn Zilbert (enigmatic)
This patch adds the camera data block type to the oops schematic view of the outliner. It also includes a little bit of code cleanup in the oops files.
---------------------------------------------------
Snappy stuff
* Align rotation with snapping target: rotate the object, aligning it with the target (object mode only - temporarily) (New icon in the header when snap is turned on)
* Snap to different mesh elements (face, edge, vertice): snapping target slide on faces and edge or use exact position of vertice. When using Align rotation with edge snapping, the normal is interpolated as you slide along.
Snaps correctly to derived mesh (sculpt, modifiers, ...) and duplis. In object and edit mode.
NOTE: The snapping code is now based on faces, so even if you're snapping to vertices or edges, it will not work on meshes without faces. This might change if needed.
----------------------------------
Arith:
- axis angle to quat conversion function
- short to float / float to short normals conversion function (eventually, we could go over the go and replace copy/pasted code everywhere)
- ray triangle intersection (to complement the line triangle intersection function)
View:
- viewray / viewline (get near plane point under mouse and ray normal/far point)
Particles:
- extract viewline from brush_add function
view: noclip version of int and float projection. Also project from behind the view's position and return coherent values for near clipping
transform: use the above functions for 2d center and helpline drawing
NOTE: the result for centers behind the camera (in perspective) isn't 100% perfect in the case of rotations because they always use the centered view vector as rotation axis and not the one aligned with the 2d center. Changing this would not be desirable anyway. At least it's predictible now.
* [#13394] Sequencer: if internal strips have handles selected, dragging the metastrip changes the meta length
* Extend did not work correctly on metastrips when the nested seq's are out of the meta's frame range, added an argument to seq_tx_get_final_left/right
that returns the frame clipped by metastrip(s) if any.
Since these conflict with loop select its now an option from the mesh tools panel. also made it possible to alt+rmb and alt+shift+rmb to mark other edge flags (creases,
bevel weights, sharp edges)
Scale and Repeat fields in NLA Transform Properties panel will now ignore negative values instead of clamping them to a near-zero value, which can easily be confused with the strip being 'destroyed'. This shouldn't affect other interface elements, as this change has only been used here.
(Note: negative scaling should be avoided)
[#10312] Append Link (image browser) bug if combined with Open window
The only place where the special handling in newspace is relevenant is when
opening it with the windowtype_pupmenu. All other overlaying windows( render in image space, scriptspace)
should leave imagebrowser/filebrowser space alone.
removed frame numbering from BLI_convertstringcode into its own function (BLI_convertstringframe), many uses of BLI_convertstringcode were passing dummy frames values anyway.
in cases where adding the current frame number to a filename is needed run BLI_convertstringframe(...) after BLI_convertstringcode(...)
There are some cases Im not sure BLI_convertstringframe is needed, these have been commented as todo, but at least have the same functionality they used to.
* Added a new tool "Synchronise with Armature" (found under Channels->Grouping), which synchronises the grouping of action-channels and the grouping of their relevant bones.
This only works when the active object is an armature, and the action isn't pinned. All of the action's action-channels are removed from their groups, and are added back into groups according to the current grouping of their corresponding bones.
A bit of testing for weird cases is needed.
* Group colours are now not drawn if the group originally was using the 'default' colour-set.
was calling screenmain() before executing the python script which meant it was never executed (therefore no crash :) )
Moved screenmain() back to the the end of main() and added a TESTBASELIB_BGMODE which checks for G.vd and uses the scene layer if its not there. Of course python should not be running stuff that uses G.vd :/
Also made python scripts stay attached to screens when LOAD UI is disabled. This means you can load a new blend file and the python console can stay open, has been tested for a while in the apricot branch.
This means when moving large projects with many images/videos/sounds is possible with 'File, External Data, Find Missing Files'.
- needed so we can put peach animatic, glrenders & testrenders on the dvd.
also datatoc.c - brecht's fixes from apricot.
=======================
Caching and Baking:
- The point cache is now cleared on DAG_object_flush_update(), and not cleared for time dependency graph updates.
- There is now a Bake button instead of Protect. Also cache start and end frames were added to softbody and particles.
- The cloth autoprotect feature was removed.
- The Ctrl+B menu now also bakes cloth and particles next to softbody and fluids. Additionally there are now frree bake and free cache menu entries.
- The point cache api has been changed. There is now a PTCacheID struct for each point cache type that can be filled and then used to call the point cache functions.
- PointCache struct was added to DNA and is automatically allocated for each physics type.
- Soft body now supports Bake Editing just like cloth.
- Tried to make the systems deal consistently with time ipo's and offsets. Still not sure it all works correct, but too complicated to solve completely now.
Library Linking:
- Added some more warnings to prevent editing settings on library linked objects.
- Linked objects now read from the cache located next to the original library file, and never write to it. This restores old behavior for softbodies. For local simulation the mesh and not the object should be linked.
- Dupligroups and proxies can't create local point caches at the moment, how to implement that I'm not sure. We probably need a proxy point cache for that to work (ugh).
Physics UI:
- Renamed deflection panel to collision for consistency and reorganized the buttons. Also removed some softbody collision buttons from the softbody panel that were duplicated in this panel for cloth.
- Tweaked field panel buttons to not jump around when changing options.
- Tabbing e.g. Soft Body Collision into the Soft Body panel, it now only shows Collision to make the panel names readable.
- I tried to make enabled/disabling physics more consistent, since all three system did things different. Now the two modifier buttons to enable the modifier for the viewport and rendering are also duplicated in the physics panels. Toggling the Soft Body and Cloth buttons now both remove their modifiers.
- Fixed modifier error drawing glitch.
Particles:
- Particles are now recalculated more often than before. Previously it did partial updates based on the changes, but that doesn't work well with DAG_object_flush_update() ..
- Fixed memory leak loading keyed particle system. Now keys are not written to file anymore but always created after loading.
- Make particle threads work with autothreads.
Continue Physics:
- The timeline play now has a Continue Physics option in the playback menu, which keeps the simulations going without writing them to the cache.
- This doesn't always work that well, some changes are not immediately updated, but this can be improved later. Still it's fun to get a feel for the physics.
Todo:
- Point cache can get out of sync with and undo and changing a file without saving it.
- Change the point cache file format to store a version (so old point cache files can be either converted or at least ignored), and to do correct endian conversion.
- Menu item and/or buttons for Ctrl+B.
- A system("rm ..") was changed to remove() since the former is very slow for clearing point caches. These system() calls were already giving trouble in a bug in the tracker, but really most use of this system("") should be changed and tested.
- The Soft Body Collision and Clot Collision panel titles don't mention there's point cache settings there too, doing that makes them unreadable with the default panel setup.. but may need to make the names longer anyway.
-Handling of fluid particles was not coded at all
-Now things should work properly, but as fluid particles are not very familiar to me I'd appreciate some thorough testing
stuff used for peach to the standard <GL/glu.h>
the mesa stuff was needed for the machines for peach but its
not the stanard location of the headers, now that its not
needed were switching it back.

Initial commit of Separate tool for Armatures. Currently, the functionality is hidden behind a temporary patch, as there are still issues to be worked out (crashes under certain conditions and a re-linking issue). It may remain like this for the release if I can't get it to work correctly.
Note:
- Hotkey for separate is Ctrl-Shift-P (it's a bit clumsy, and isn't consistent with P for separate for meshes, but Select Parent(s) is better as P)
active face drawing didnt always work since it used the last selected element for drawing.
moved stipple into glutil.c rather then using 128 bytes in the stack for each stipple draw.
A lot of fixes for anim_startofs / anim_endofs:
* crashed when striplen was 0 and startstill / endstill still in use
* made it work for Audio (HD and RAM)
* made it work for Image Sequences
* added a new cutting tool, that uses anim_startofs / endofs instead of
startofs / endofs. This is now the default and called "hard cut"
* moved old cutting method to "Shift-K" and renamed it "soft cut"
Fixed a long standing bug in IMB_dupImBuf: refcounter should be better 0
within the duplicated ImBuf...
Finally removed this strange STRIPELEM_META mumbo jumbo.
On a way to asset management: made METAs behave like true input strips:
* proxying should work
* input filter options should work (including transform and color balance :)
* IPOs now work in replace mode
Quick feature for setting Preview Range in Action Editor: the hotkey Ctrl-Alt-P sets the Preview Range so that it matches the extents of the active action.
