Structures

• A reference
• We are getting closer to the goal.
• A transporter that "grows" with the game
  • Right now the data is stored in the wrong place.
  • I would like the ability to turn levels on and off
  • I would like level names, not just map names.
• It's starting to look like three parallel arrays
• But structures can save us.
• Build a structure type
  • I want a FloorT
  • It should hold a name (level name) , string (level description ) and a bool (active)
• Build a new structure type
  • Click in the Content Browser and select
  • Blueprints, structure (NOt Blueprint Actor)
  • 
  • Now just add the fields.
  • 
• You can now build an instance or even an array of these.
• Let's build an BP_TransportDir
  • The normal box and cube for collision.
  • But add a FloorT variable
    • Make it an array.
    • Initialize the first record.
  • On EventBeginPlay, enable input
  • Add a event key p event to print all elements in the array.
    • Add a foreach
    • Hook up the array.
    • Note that you can split the pin for the array element.
    • Or you can use a "Break" note.

  • I added a keypress a
    • This adds another level.
    • 
    • Note the MakeFloorT node.
  • Finally a keypress z
    • This toggles the active flag on the first element.
    • Notice the SetArrayElem node
