Title: [SOLVED] Null Reference Exception with GoToStateByName
Post by: hockeygoalie78 on January 21, 2020, 10:07:11 AM

I have been attempting to get my FSM to go to a particular state given the name of it in string format. I'm using the GoToStateByName action (which I have downloaded separately and added into my project), but I am unable to get it to work properly. I have the correct name stored in a variable, but when I use the action it gives me a null reference exception on the Fsm sourceFsm on line 85. Does anyone know what might be causing that?

For reference, I found the GoToStateByName action here:

Hi.
You might have an outdated version of the action, it is best to use the Ecosystem (https://hutonggames.fogbugz.com/default.asp?W1181) to download custom actions

for the name, also make sure there is no space at the end or beginning.

Getting it from the Ecosystem rather than the Git repository worked, thanks!
