This package provides a simple and easy to use behavior tree API in pure dart.
Behavior tree is a very common way of implementing AI behavior in game and robotics. Using this, you can break-down a complex behavior of an in game AI, into multiple smaller nodes.
Features
- Nodes
- Composite
- Sequence: Continues execution until one of the children fails.
- Selector: Continues execution until one of the children succeeds.
- Decorator
- Inverter: Flips the status of the child node.
- Limiter: Limits the number of ticks for child node.
- Task
- Task: Executes a given callback when ticked.
- AsyncTask: Executes an async callback when ticked.
- Condition: Checks a condition when ticked.
- Composite
Getting started
Add this package to your dart project using,
dart pub add behavior_tree
Usage
- Create a behavior tree.
final treeRoot = Sequence(
children: [
Condition(() => isHungry),
Task(() => goToShop()),
Task(() => buyFood()),
Task(() => goToHome()),
Task(() => eatFood()),
]
);
- Tick the root node to update the tree.
final treeRoot = ...;
treeRoot.tick();
