Child Actors

• I want composition.
• You do this with Child Actors.
• First I build a BP_Display
  • This is an actor blueprint with just a Text Render object
  • I have a single function NewMessage
    • This takes a string
    • And sets the text to be that string.
  • 
• I have another class that I want to have a display like this.
  • Add a ChildActor component.
    • Click on this and select the Child Actor Component in the details panel
    • 
    • Set Child Actor Class to be the type of blueprint you want.
• Accessing the ChildActor
  • Unfortunately just accessing the child actor component is insufficient.
  • You need to add a get child actor node
  • Then you need to cast it to the proper child actor.
