Apparently this is a known issue in 6.3 that unity will fix:

Hopefully in the next beta...?

Hi, I keep having this error spam in Unity 6.3 with PlayMaker. Please fix this soon.

Error:

Thank you.

Hey guys

I'm studying MMT in my first semester right now.
For our 3D Prototyping lesson we are supposed to create a simple prototype in Unity using Playmaker (our teacher gave us a free to use Playmaker version 1.9.9 to use for this project)

We are supposed to make something simple so I though I would try to make a 3D Battleship prototype. In the image you can see that I have so far only created two 8x8 planes and a few "ships" as blocks.

I am really struggling to get this off the ground though. I have no experience whatsoever with Playmaker or Unity. I have tried using Grok to help me with the action setup but eventually those chats just spin in circle.

What I would like to know is, if you know any tutorial that could help me get started with this. All I want is a somewhat playable prototype to present in class.

If you think this project is a little too complex for a total beginner (my teacher said it might be) please let me know so I can search for another idea (if you have one let me know lol)

Hey Alex,

Just wanted to give an update! I managed to get it working.

I ended up having to copy and paste variables from an older exported PlayerGlobal variables to a a newly created PlaymakerGlobal one. This worked quite well.

The playmaker/wp8 DLL issue wasnt resolved with any tools but it turns out it was only on a few prefabs in the project,

I resolved it by copying and then pasting the FSM component onto the prefab at hand and then deleting the old ones and all is well in the world.

Alex, I really appreciate your help - it pretty much saved my project and I owe you a few beers should we ever cross paths!

Cheers!!
