MotionEffect.ByX Property

  • Article
PowerPoint Developer Reference

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.

Syntax

expression.ByX

expression   A variable that represents a MotionEffect object.

Return Value
Single

Remarks

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.

Example

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

Visual Basic for Applications 
  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, _
     effectId:=msoAnimEffectCustom)
Set animBehavior = effCustom.Behaviors.Add(msoAnimTypeMotion)

'Specifies animation motion
With animBehavior.MotionEffect
    .<strong>ByX</strong> = 50
    .ByY = 50
End With



End Sub
