MotionEffect.ByX property (PowerPoint)

Sets or returns a Single that represents scaling or moving an object horizontally by a specified percentage of the screen width, depending on whether it used in conjunction with a ScaleEffect or MotionEffect object, respectively. For example, a value of 50 for a motion effect means to move the object half the screen width to the right. Read/write.


expression. ByX

expression A variable that represents a MotionEffect object.

Return value



Negative numbers move the object horizontally to the left. Floating point numbers (for example, 55.5) are allowed.

To scale or move an object vertically, use the ByY property.

If both the ByX and ByY properties are set, then the object is scaled or moves both horizontally and vertically.

Do not confuse this property with the By property of the ColorEffect, RotationEffect, or PropertyEffect objects, which is used to set colors, rotations, or other properties of an animation behavior, respectively.


The following example adds an animation path; then sets the horizontal and vertical movement of the shape.

Sub AddMotionPath()

    Dim effCustom As Effect
    Dim animBehavior As AnimationBehavior
    Dim shpRectangle As Shape

    'Adds rectangle and sets effect and animation
    Set shpRectangle = ActivePresentation.Slides(1).Shapes _
        .AddShape(Type:=msoShapeRectangle, Left:=300, _
        Top:=300, Width:=300, Height:=150)

    Set effCustom = ActivePresentation.Slides(1).TimeLine _
        .MainSequence.AddEffect(Shape:=shpRectangle, _

    Set animBehavior = effCustom.Behaviors.Add(msoAnimTypeMotion)

    'Specifies animation motion
    With animBehavior.MotionEffect
        .ByX = 50
        .ByY = 50
    End With

End Sub
