Few questions about Behavior Trees

I just got to making simple AI for my project and few questions arise

Is there a way to fail sequence after specified number of children nodes fail?
Can I invert the child node result?
Load different tree from within the tree?

"Is there a way to fail sequence after specified number of children nodes fail? "
There’s a decorator that loops the node over specified time, and fails

“Can I invert the child node result?”
If you are using the number 1, use -1.
Other than that, you need to specify.

“Load different tree from within the tree?”
There is a node called “Run Behavior Tree” or something that can be ran in the BT.

1.What I meant was node that traverse the children one after another but doesn’t break at first fail, it breaks after given number of fails

  1. By inverting result I meant sort of NOT decorator, if child is successful it fails and the opposite.

3.ok

  1. Have you tried a service? It can be applied to top of the node sequence and fail itself after a specified time.
  2. In some decorators, they have an inverse checkbox. You can look into that.
