FCurve.GetKeysBetween

Introduced

v6.0

Description

Returns a collection of FCurveKey objects representing keys on the function curve between the StartFrame and EndFrame.

C# Syntax

FCurveKeyCollection FCurve.GetKeysBetween( Object in_StartFrame, Object in_EndFrame );

Scripting Syntax

oReturn = FCurve.GetKeysBetween( [StartFrame], [EndFrame] );

Return Value

FCurveKeyCollection

Parameters

Parameter Type Description
StartFrame Variant The start time of the range. Must be less than the EndFrame value.

Default Value: The first key frame on the fcurve.

EndFrame Variant The end time of the range.

Default Value: The last key frame on the fcurve.

Examples

JScript Example

// 

// This example illustrates how to get the keys on an fcurve

// in a specific time range

// Create a new scene

NewScene(null, false);

// Create a null

oNull = Application.GetPrim("Null");

// Get the posx parameter of the null

oPosX = oNull.posx

// Create array of time-value pairs

aKeys = new Array( 0.00, 5.00,

				1.00, 6.00,

				2.00, 7.00,

				3.00, 8.00,

				4.00, 9.00,

				5.00, 10.00 );

// Create an empty FCurve

oFCurve = oPosX.AddFCurve2( null, siStandardFCurve );

// Set the fcurve keys

oFCurve.SetKeys( aKeys );

var keys = oFCurve.GetKeysBetween(2.0, 4.0);

for (var i = 0; i < keys.Count; i++) 

{

	Application.LogMessage( 'Time: ' + keys(i).Time + ', Value: ' + keys(i).Value, siInfo );

}

// Produces the following output:

//

//INFO : Time: 2, Value: 7

//INFO : Time: 3, Value: 8

//INFO : Time: 4, Value: 9
