    Add a few comma-separated actions to Comma seperated actions field (e.g jump, kick, dance, etc.).
  2. 2.
    The character will select one of the actions based on the conversation and run any event with the same name as the action in the Action Graph.

Notes

  • The demo stage includes only talk and idle animations. However, it is possible to add more animations and trigger them using the action selected by the character. More on that in the future.
