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 Required. An expression that returns one of the objects in the Applies To list.
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.
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
.ByX = 50
.ByY = 50
End With
End Sub
