If you aren't using a movement behavior I recommend using lerp() — no plugins required.
Create instance variables for StartingX, FinishingX, Progress, & Speed.
Group(initially disabled)
-Every Tick
--Set Position to lerp(StartingX, FinishingX, Progress)
--Add Speed to Progress
-If Progress > 1 Disabled Group
Then when its time to move you set the starting and finishing variables, set progress to 0 and enable the group. Presto!
