+		BTSelector executes its child tasks sequentially, from first to last, until any child returns [code]SUCCESS[/code]. If a child task results in [code]FAILURE[/code], BTSelector will immediately execute the next child task until one of them returns [code]SUCCESS[/code] or all of them result in [code]FAILURE[/code]. BTSelector and [BTSequence] are two of the most common building blocks of behavior trees. Essentially, while [BTSequence] is similar to a boolean AND operation, BTSelector is similar to a boolean OR operation. Selectors enable the behavior tree to respond to changes in the environment and trigger transitions between various fallback behaviors.

BTSequence and [BTSelector] are two of the most common building blocks of behavior trees. Essentially, while [BTSelector] is similar to a boolean OR operation, BTSequence is similar to a boolean AND operation. Sequences enable the behavior tree to compose complex behaviors from a chain of simpler tasks.
