PlotAndApplyActions

Introduced

7.5

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

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

Parameters

Return Value

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

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.
var oParamsColl = new ActiveXObject( "XSI.Collection" );
oParamsColl.Add( oSphere + ".kine.local.posx" );
oParamsColl.Add( oSphere + ".kine.local.posy" );
oParamsColl.Add( oSphere + ".kine.local.posz" );
oParamsColl.Add( oCone + ".kine.local.posx" );
var oActionsColl = PlotAndApplyActions( oParamsColl.GetAsText(),
          "plot", 40, 60, 2, 20, 3, false, null, null, true, true, false );

var iActionsCount = oActionsColl.Count;
if( iActionsCount > 0 )
{
   for( var i = 0; i < iActionsCount; i++ )
   {
       var oAction = oActionsColl.Item( i );
       var oSourceItemsFound = oAction.SourceItems;
       var iSourceItemsCount = oSourceItemsFound.Count;

       if( iSourceItemsCount > 0 )
       {
          Application.LogMessage( "Found the following source items in " + oAction + ":" );
          for( var j = 0; j < iSourceItemsCount; j++ )
          {
              Application.LogMessage( "\t" + oSourceItemsFound.Item( j ).Name );
          }
       }
       else
       {
          Application.LogMessage( "No source items found in " + oAction + "." );
       }
   }
}
else
{
   Application.LogMessage( "No actions created." );
