Hi, I was wandering if I can make the random node return unique result - different than the last one. I have simple navigation targets and I want my character to choose different navigation target than the previously chosen. Is that possible?
Thanks
Well, the “weight” of the node will (I believe) determine the probability of being chosen by the Random node. So you could have a variable update the weight of the child nodes. So if random chose 2 out of 4 first, you could set the weight of 2 to zero or close to zero to ensure it wouldnt be picked again. Does that make sense?
Hm ok I will try it that way. I wanted to know if I can make my own random node, to extend the existing one, but I cannot seem to find an example.
Yes, you can extend RAINDecision to your own randomed-node.
However, it will not have weight field in child nodes because editor encapsulation.
Inheriting built-in random is useless, too.
