## FCurve.DependsOnFrameRate

### Introduced

v5.0

### Description

Sets or returns the fcurve's dependency on the frame rate (time) as a Boolean (true if the fcurve is dependent on the frame rate). If the fcurve is set as time-dependent it will adjust when the scene's frame rate changes. Typically you don't want this to be set to true when the fcurve is a profile curve that does not use time as a factor.
Animation fcurves are typically time-dependent; that is, they generally represent change in a parameter's value over time (for example, a change in an object's X position from frame 10 to frame 90). Profile fcurves usually do not use frame values on either axis. Profile fcurves are used in deformations to allow a user to finetune an effect (for example, the Bulge operator uses percentage of amplitude on the Y-axis over distance from the deformation center on the X-axis).

### C# Syntax

    // get accessor
    Boolean rtn = FCurve.DependsOnFrameRate;
    // set accessor
    FCurve.DependsOnFrameRate = Boolean;

### Examples

#### JScript Example

    /*
            This example illustrates how to create an fcurve and set its X axis
            to be time independent. That means that the FCurve will not rescale when the
            scene frame rate changes

    // Create a new scene
    NewScene(null, false);

    // Create array of time-value pairs
    aKeys = new Array( 30.00, -5.00, 50.00, 5.00 );
    // Create an empty FCurve
    oFCurve = oPosX.AddFCurve2( null, siStandardFCurve );

    oFCurve.SetKeys( aKeys );
    // Validate that the key parameter does not change with the frame rate
    oFCurveKey = oFCurve.Keys(0);
    Application.LogMessage( 'oFCurveKey.Time before = ' + oFCurveKey.Time, siInfo );

    oFCurveKey = oFCurve.Keys(0)
    Application.LogMessage( 'oFCurveKey.Time after = ' + oFCurveKey.Time, siInfo );
    // Produces the following output:
    //
    //INFO : oFCurve.DependsOnFrameRate before = true
    //INFO : oFCurve.DependsOnFrameRate after = false
    //INFO : oFCurveKey.Time before = 30
    //INFO : oFCurveKey.Time after = 30
    // Because the FCurve was set as being time independant, the
    // key times are not changed when changing the frame rate
    // of the scene.
