# State Machine Nodes

### StateMachine Controller

Executes the current state. OnEnter, OnUpdate and OnExit calls.\
The FSM Controller always starts with the first (top) state.

### Actions

Executes connected FSM action nodes.

### Action Split

Splits a FSM execution into OnEnter, OnUpdate and OnExit. Must be used to execute conventional Logic nodes.

### Switch State

Switch current state to a new state

### Stop StateMachine

Stops the FSM controller. FSM controller must be called again to be restarted.

### Is State

Checks if current state is selected state. Executes yes or no.
