## FCurveKeyCollection

Related C++ Class: CFCurveKeyRefArray

### Introduced

v1.5

### Description

A collection of FCurveKey objects that represent the keys in the FCurve. The FCurveKeyCollection object is accessed through the FCurve.Keys property. This collection is 0-based.
Keys in an FCurveKeyCollection are maintained in ascending order by parameter and duplicate key entries are disallowed. Also, an FCurveKeyCollection can only hold keys from the same fcurve so any attempt to add keys from another FCurve to an existing collection will fail.

### Methods

Add | AddItems | Filter | GetAsText
GetMaxKeyFrame | GetMaxKeyValue | GetMidKeyFrame | GetMidKeyValue
GetMinKeyFrame | GetMinKeyValue | Remove | RemoveAt

### Properties

Count | Item |  |

### Examples

#### VBScript Example

    set oCube = Application.ActiveProject.ActiveScene.Root.AddGeometry("Cube","MeshSurface")

    dim aValues

    aValues = 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)

    set oFCurve = oCube.PosX.AddFCurve2( aValues)

    ' Write the fcurve keys

    for each k in oFCurve.Keys

    	LogMessage k.Name &" Value: " & k.Value

    	LogMessage k.Name &" Locked: " & k.Locked

    	LogMessage k.Name &" Left: " & k.Left

    	LogMessage k.Name &" Right: " & k.Right

    	LogMessage k.Name &" LeftTanX: " & k.LeftTanX

    	LogMessage k.Name &" LeftTanY: " & k.LeftTanY

    	LogMessage k.Name &" RightTanX: " & k.RightTanX

    	LogMessage k.Name &" RightTanY: " & k.RightTanY

    	LogMessage k.Name &" Interpolation: " & k.Interpolation

    	LogMessage k.Name &" Flags: " & k.Flags
