PlotAndApplyActions

Introduced

v7.5

Description

Creates and returns new actions by plotting values from consecutive frames of an animation. Actions are created under models containing animated parameters matching the specified list and you can choose whether or not to apply the actions back to the model and then optionally delete them.

Scripting Syntax

oReturn = PlotAndApplyActions( [InputObj], [Name], [StartFrame], [EndFrame], [StepFrame], [FCurve Kind], [DefaultSegKind], [Fit FCurve], [Fit Tolerance], [ProcessContRots], [Apply], [Paste], [Delete], [Type], FrameSet );

Return Value

Returns the created actions (a XSICollection object). Returns nothing if you chose the Delete option.

Parameters

Parameter Type Description
InputObj String List of parameters to plot into actions.

Default Value: Marked values in current selection

Name String Name for the actions

Default Value: "Action"

StartFrame Double First frame to plot

Default Value: 0

EndFrame Double Last frame to plot

Default Value: 0

StepFrame Double Step between frames

Default Value: 1

FCurve Kind Integer What kind of fcurve do we want to plot to?

Default Value: 20

Possible Values:

Description:

10 BOOLEAN (value true or false)
15 INTEGER (staircase-like fcurve with integer values)
20 STANDARD (fcurve with spline/linear/constant interpolation)
30 RAWDATA (linear fcurve: less storage than a standard fcurve but with linear interpolation only)
DefaultSegKind Integer What kind of interpolation do we want for the resulting fcurves?

Note: Only relevant when FCurveKind is 20 (Standard).

Default Value: 3

Possible Values:

Description:

1 CONSTANT
2 LINEAR
3 CUBIC
Fit FCurve Boolean Do we want to fit an fcurve through the plotted values?

Default Value: False

Fit Tolerance Double What tolerance do we want for the fit?

Default Value: 0.01

ProcessContRots Boolean Do we want to process rotation curves to ensure their continuity?

Default Value: True

Apply Boolean Do we want to apply the actions after plotting them?

Default Value: True

Paste Boolean If applying, should they be applied using paste (merging with existing fcurves on parameters)?

Default Value: False

Delete Boolean After plotting and applying, do we want to delete the actions? Only valid if Apply is specified.

Default Value: False

Type Integer 0 for Frame Range, 1 for Frame Set

Default Value: 1

FrameSet Array Array of scene time in seconds to plot each frame at.

Examples

JScript Example

//
// This example sets up one model with a sphere and another with a cone,
// plots various parameters to an action source for each model,
// and then prints out the new sources.
//
// Set up the scene.
NewScene( null, false );
var oSphere = CreatePrim( "Sphere", "NurbsSurface", "MySphere" );
var oCone = CreatePrim( "Cone", "NurbsSurface", "MyCone" );
CreateModel( oSphere, "SphereModel" );
CreateModel( oCone, "ConeModel" );
// Set some keys at frames 1 and 100 with it moving diagonally.
Translate( oSphere, -6, 3, 0, siAbsolute, siView, siObj, siXYZ );
SaveKey( oSphere + "/kine.local.pos", 1 );
Translate( oSphere , 6, -3, 0, siAbsolute, siView, siObj, siXYZ );
SaveKey( oSphere + "/kine.local.pos", 100 );
Translate( oCone , 6, -3, 0, siAbsolute, siView, siObj, siXYZ );
SaveKey( oCone + "/kine.local.pos", 1 );
Translate( oCone , -6, 3, 0, siAbsolute, siView, siObj, siXYZ );
SaveKey( oCone + "/kine.local.pos", 100 );
// Plot the positions of the sphere and the Y position of the cone every two frames
// between frames 40 and 60 and store the result in a standard fcurve with cubic
// interpolation. Don't fit the fcurves and don't care about continuous rotations
// since we're plotting positions. After plotting to actions, apply the plotted
// animations back onto the sphere and the cone using "paste" so existing keys outside
// the plot range are not affected. Don't delete the actions after applying them.
