Go to next state

• Action:Request, get and go to next state by event. Style of behavior tree.

  1. Action:Request, go to next state which determined by

  2. Condition:On transfer logic(Curstate)

     1. set next state by Action:Set next state

        • State will not change if Action:Set next state does not invoke.

• Action:Go to state, go to next state directly.

State changing actions

Add actions under these conditions, which will be triggered when state is changed from Expression:PreState to Expression:CurState

1. Condition:On state changed

2. If Condition:On transfer is in event sheet,

   • Condition:On state changed

   • Else

     1. If Condition:On exit is in event sheet,

        • Condition:On exit
        • Else Condition:On default exit

     2. If Condition:On enter is in event sheet,

        • Condition:On enter
        • Else Condition:On default enter

DO NOT change state (Action:Request or Action:Go to state) under these conditions directly, or inserts a System action: wait (0) above Action:Request or Action:Go to state, which could suspend remaining actions until next tick.

Initial state

Set initial state in property Initial state.

Debug

Dump current state by Expression:CurState under Condition:On state changed, to track the state changing.
