Behavior Trees (BTs) are a way to model decision-making logic,
key problem solved by behavior: What to do next ?
Each action needs to know "Did I Succeed or Fail?"

The ancestors decide "What to do next?"
Composition Of Actions
- Fallback / ? / or
- Sequence / -> / and
Fallback
- Eat Sandwich or Eat apple
- rule: if failure then tick next else return "same as chile"

Sequence
- Peel the banana and eat the banana
- Rule: If success then tick next else return "same as chile"
