ActiveSequence ticks each child in order.

Parallel updates all its children in parallel, i.e.

PersistentSequence updates each child in order.

RandomSelector creates a new random selector node.

RandomSequence works just like Sequence, except it shuffles the order of its children every time it is re-updated.

Selector updates each child in order, returning success as soon as a child succeeds.

Sequence updates each child in order, returning success only if all children succeed.
