Hi, I'm not able to reproduce this error here, but I suspect you have a script called "MoveTowards" in the global namespace (not using a namespace). Search your project for "MoveTowards" to find the script. That script should really use a namespace, but a workaround is to edit MoveTowardsActionEditor.cs to: Code (CSharp): var moveTowardsAction = (HutongGames.PlayMaker.Actions.MoveTowards) target; I'll include this change in the next update since MoveTowards is a common name and people don't always use namespaces. However if MoveTowards is a third party script I encourage you to also contact the author and ask them to use a namespace. Hope this helps!
