=== 13.03.16: NLA Editor ===

Nla Editor: None Linear Animation Editor.

these are some idears.

=== 13.03.20: problems ===

make new action from current action
* this can be done.

auto sync length
* bool switch: auto sync length.
* bool switch: sync all strips with same action.
* problems with strips being to big.

blend interpolation
* not sure how it does it at the moment. but will need support for multiple strips.

change object
* should be ok.

smooth transition
* not sure about this yet. todo with transition between strips.

=== 13.03.21: what do people do ===

* first usually, make an animation on the timeline, then freeze it.
* edit strip.
* duplicate strip.
* rename strip.
* bool switch: auto sync length.
* bool switch: sync all strips with same action.
* make new strip action from strip action.
* copy object[A].action to object[B].action then delete object[A].action.
* auto snap enum.
* folder feature, dont know what for: (00:00 youtube /watch?v=IBRqmeErOHU)
* its better for repetative game animations. or loop, like bird wings. or loop background animation.
* blend is used to blend animations. walk + duck = walk to duck walk. (5:00 & 9:00 & 10:20: youtube /watch?v=x2kkOROZPvE)
* repeats good.
* copy paste.
* mabey good to add code to move keyframe point in nlastrip tweak mode, like dopesheet editor.

=== 13.03.16: Nla Editor vs Composer ===

With composers X is time. Y can have multiple modes.

Y Main
* Y is usually a sound effect, like a type of synth, for example a cat or dog sound.
* Moving the data block to the different track would change the sound of the notes.

Y Edit
* Composers usually have edit mode also, if its a MIDI, this is change the pitch of the notes.
* If its a raw sound signal, sometimes you can draw the signal.
* In this mode will not see any other data block.

NlaStrips are animation keyframes in a block.

Nla Editor in Main mode doesnt require an Y property.
* Sometimmes you may want to overlap animations or just move them about.
* So its better to keep it free from Y.
* Though it shouldnt be ruled out, mabey it code have different Main_modes.

=== 13.03.16: NlaTest ===

I made two NlaStrips by by adding keyingsets then pressing freeze to turn them into NlaStrips.

Then i duplicated them.

[[File:NlaTest.PNG|500px]]

NlaTracks
* NlaTrack
* NlaTrack.001
* NlaTrack.002
* NlaTrack.003

NlaStrips
* A
* A.001
* A.002
* A.003
* A..
* B
* B.001
* B.002
* B.003
* B..

Actions
* CubeAction
* CubeAction.001

Actions are the keyframes.

Transitional strips to process outer keyframes.

=== 13.03.20: NlaStrips ===

The NlaStrips have Actions.

NlaTrack > NlaStrip > Action > Keyframes

When you duplicate the Strip it uses the same action.

To edit the keyframes of a NlaStrip enter Tweak Mode (TAB).

If you modify the action keyframes of one strip the other strips are modified.

=== 13.03.20: Sync Action Length ===

You can sync the NlaStrip length with: Header: Edit: Sync Action Length.

This will set strip length for the strips selected.

=== 13.03.20: copy set new NlaStrip Action===

Make a NlaStrip Action unique (copy set).
* Properties: Animation Data: Brows Action to be linked.
* select the action you want to copy.
* this will add the action.keyframes to the timeline.
* press Properties: Animation Data: [+].
* this will make a new action with the same keyframes.
* press snowflake.

=== 13.03.20: no track ===

[[File:K_nlades.PNG|600px]]

=== 13.03.20: auto sync length ===

auto sync length
* bool switch: auto sync length.
* bool switch: sync all strips with same action.
* problems with strips being to big.

bool switch: auto sync length.

comes with problems.

after editing if the strip maybe too big.

so two options, jump track, or be passive, this would be a bool switch.

if passive the track would be processed like an overlapping action.

=== 13.03.20: stack interpolation ===

i think this is how to process multiple propeties.

this would be after each fcurve interpolation.

[[File:K_stack.PNG|600px]]

=== 13.03.20: Blend ===

Not sure about this yet.

This is when keyframes Blend/interpolation.

Automaticly setup when NlaStrips overlap.

When blend is used on an NlaStrip, the NlaTrack becomes dominate.

So the next strip must be on the same track (mabey loop bug).

=== 13.03.22: mesh blend ===

NLA Editor: Properties: Active Strip

Extrapolation and Blend, this is for mesh blending.

By default its on Replace.

Add will usually make the mesh bigger because there are two meshes it add them together.

Subtract will shrink the mesh.

Playback Settings:

Reversed, will play the strip backwards.

=== 13.03.22: blend ===

lets say im auto blending these.

[[File:K_nla_blend.PNG]]

[ cube up ] bottom_left to bottom_right.

[cuberight] bottom_right to top_right.

with [ cube up ] blend starts at bottom and goes to top. 0 - 1.

with [cuberight] blend starts at top and goes to bottom. 1 - 0.

the auto blend creates a curve motion.

=== 13.03.22: blend replace ===

[[File:K_nla_blend_rep.PNG]]

move
* 2 keyframes
* Time 00.00 - 20.00
* X Location 0.0 - 5.0
* Y Location 0.0 - 0.0
* Z Location 0.0 - 0.0
* Auto Blend In/Out: off
* Blend In: 0.000
* Blend Out: 0.000

top
* 2 keyframes
* Time 05.00 - 15.00
* Z location 3.0 - 3.0
* Auto Blend In/Out: off
* Blend In: 5.000
* Blend Out: 5.000

time
*at time 0, 'move' has 1.0 influence.
*at time 5, 'top' starts to blend in.
*at time 10, 'top' replaces 'move'. 'top' has 1.0 influence, 'move' has 0.0 influence.
*at time 15, 'top' blends out and 'move' has 1.0 influence.

=== 13.03.22: tweak blend tab ===

the nlastrip_action and nla_blend tabs would be shown in tweak mode (TAB).

[[File:K_nla_des2.PNG|600px]]

nla00: the tracks would show strips for all objects in the scene.

with this one, be easier to change strip object.

nla01: object seperated version.

=== 13.03.24: Auto blend ===

These work good.

[[File:K_nla_auto_blend.PNG]]

The second one, 'left' is blending 'right' and 'right.001' at the same time.

=== :::::::: code :::::::: ===

=== 13.03.16: c data ===

Note that keyframes and drivers are Fcurves (AnimData.drivers).
* Fcurves have a funny IO using ChannelDrivers and rna_path.
* BezTriple is the keyframe array.

Heres some branches not all.
