Now I'm in the section 13. Make a Decorator of the Behavior Tree Quick Start Guide, and at the step 6. Create the following graph in that new function. I just mimicked the blue print in the picture below as instructed, but when I compiled, it said "The execution path doesn't end with a return node." in the Compiler Results at the bottom.
the picture in the step 6 of section 13
what I mimicked
As in the pic of mine, NOTE appears at the bottom of Cast To Follower_AI_CON, but I don't really have any idea about it. The info which says as below should have something to do with this, but it still doesn't make sense to me.
"As this is a Function Graph, if you use the Code Snippet from the graph image above, you will only get the center portion of the graph, and the beginning and end nodes will not be connected. Just wire those connects as the image shows, and it will work just fine."
For example, I'm not quite sure what "the graph image above" and "as the image shows" means here in this section.
Please tell me why this happens and how to fix it. Thank you for your help in advance. Cheers!
