@Playmaker Team
I am a newbie in Unity and Playmaker.
I use Playmaker V1.3.2 (updated from Playmaker V1.2.1)
I got a same problem as marcos (http://hutonggames.com/playmakerforum/index.php?topic=1124.0)
but it happened on some game object.

I noticed that when game object executed the Sent Event action, it will display error.
In addition , it will occur on same game object everytime that I reload scene.

Hi,

 I have the same problem, and the current beta version seems to have fixed it.

The way to go around it is to not send events from a state that originates from the START event. you can use various technics to break the flow, but it really depends on why you are sending en event when starting. Maybe you can wait some triggers in your application, or implement a delayed event, or even try next frame Event action. Or maybe try to find a way to build your app so that it doesn't need this event being sent at Start.

Hopefully that will give you some hints to fix this.


Bye,

 Jean

@Alex Chouls
what should i do next?
Should I update to Playmaker 1.3.3 RC2 or send an error by using current version (Playmaker V1.3.2).

Backup your project, and update to 1.3.3 RC2. If you still get the error, submit a bug report from the beta...
