Extending And modifying Brain

[XainFaith]

So as the title states i am extending and modifing a brain, this is specific to the rabbit brain.

 

Now here is my issue i have extneded and modifyed the Behvioural tree of the Rabbit Brain and i know the parts of the BT i added work. I have it so that the rabbit can become a follow when feed a carrot from a safe distance and it even follows you. The problem is it persistantly runs away from you as in " fleeing " even when i had a IfNode to prevent default behaviour from occuring when it was following the player.

 

So my question is is there a component or something that is attached to the rabbit prefab itself ( iv looked nothing obveious pops out ) that cuases this behaviour.

Running away happens in the stategraph 'run' state so what I would typically do is add a 'print(debug.traceback())' call to the 'onenter' function in the 'run' state which should tell you what triggered the rabbit to start running.

print(debug.traceback())

print(debug.traceback())

 

I don't know what you're talking about...

Thanks for that information turns out the trace back was not as usfull as i would of hoped.. just noted that it was being called from the beahviour trees update etc.  But i determined in the long run that its acctually the rabbits running that causes the behaviour if i set the last param node for the follow node to be false eg( can run ) it very slowly does follow you without running away. A bit stumped as to how to fix this while still maintaing compatability at this moment. But at the very least i know roughly what is causing the behaviour.
