Welcome to Unreal Engine

• In homework 2, you are asked to complete a tutorial that is a tour of the unreal engine.
• I thought we could do a general tour today.
• I would like to point out a few things as well.
• Start with a new ThirdPerson example.
  • Note the similarity to the Content directory in the project directory and the contents of the Content Browser
  • 
  • Later we will migrate assets, and we want to put them into the content directory.
• note, most places you can build "things" there are folders.
• Note there are search bars everywhere.
  • In the tutorial he spends some time showing you how to use these.
  • Use these.
• Just like the text editor you have used for programming the last few years, if you are in game, you will be using this environment quite a bit.
  • you really should spend some time becoming proficient with it.
  • Develop good work habits now.
  • Rebecca says "Name collision is a problem"
• The content browser is where you access most of the "things" you will do something with.
• They tend to call their levels "Maps", so let's search for a map.
  • In the content browser search bar
  • Make sure you are at the Content level
  • Search for Map
  • 
  • Double click on the Starter Map
• You can play this.
  • Notice in the World Outliner there are a number of folders in use.
  • I keep falling, and don't like this, so I am going to change the Killz for the world.
    Select Settings then World Settings
    • 
    • Now in the Details Panel there is a World Setting tab
      • Search for Kill in this
      • Set Killz to be -500 (just type it in)
      • 
    • This brings up big problem 1 for me.
      • There are about 1,000,000 settings and I can't remember them all.
    • I don't like where the player is starting, I can't see the collision.
      • Search in the world outliner for Player Start
      • Drag this to near Ocean Water and see how it looks now.
  • OK, let's go back to the ThirdPersonExampleMap
    • Just click on it in the content browser.
    • Note, Unreal wants to save your changes to the Starter Map
    • Let it.
  • It would be neat if we could run between levels
    • Like most things in Unreal there are several ways to do this.
    • We will use the old way, which is fine for our purposes here.
    • This is based on This tutorial
    • Start by making a new folder in the Content Browser at the top.
      • Call this Dans_BP_Folder
    • Open it
    • Right click and select New Blueprint Class
      • It is worth noting that there are a number of classes we can select between.
      • I believe that this is a hierarchy
      • Actor is the base class.
      • Others are derived from that.
      • we want an Actor, so select that.
      • Name the new actor Dans_Transporter
      • Double click to open this
    • In the new actor
      • Search for and add a Box Collision
      • Click on the Event Graph
      • Right click and select Add Event
      • Quick search for ActorBegin and select Event ActorBeginOverlap
      • 
      • Drag off the white triangle and search for cast to third person character
      • Connect the blue line from other actor.
      • 
      • Drag off of the top control line and select Open Level (by name)
      • 
      • Right click on the Level Name button and select Promote To Variable
      • 
      • In the details panel, rename this to be Level to Load and click on the Instance Editable check box.
      • 
      • 

      • class  Dans_Transporter
           string LevelToLoad
        
        OnOverlap(actor)
           if (actor == ThirdPersonCharacter)
             OpenLevel(levelToLoad)
                     

      • Add this to the ThirdPersonExample map, make sure that you set the Level To Load to be StarterMap
      • Test it
      • Add it to the StarterMap so you can go back to the ThirdPersonExample map.
