ex1: Scripts: Implementing a smarter AI opponent

  1. Understand the DumbAI
    • Select the Enemy game object and find the Dumb AI script.
    • Open it by double-clicking on the Script entry or using "…" and selecting Edit Script.
    • Why is movement written in FixedUpdate() as opposed to Update()?
    • How is moving in a straight-line and bouncing off walls implemented?
  2. Implementing GreedyAI
    • Remove the DumbAI script from the Enemy object via "…" > Remove Component.
    • In the Project window, navigate to Assets/Scripts and attach the GreedyAI script to the Enemy, then open it.
    • Fill out the TODOs in GreedyAI.cs to make the Enemy track the position of the ball, and move back to a central position after hitting the ball.
  3. Save the file and save the scene, then play the game to check your solution.

ex2: Prefabs: Spawning powerups midgame

  1. Create the speedboost powerup game object which we want to save as a prefab.
    • Right-click in the Hierarchy window and select 3D Object > Plane. This will create a new game object.
    • Rename this game object to "Speedboost".
    • In the Inspector window assign the Tag "Speedboost" to this game object.
    • Use the Rect tool (Shortcut: T) to shape the object. Alternatively, set the scale values in the Transform component e.g. x:0.1 y:1 z:0.15 work well.
    • In the Mesh Collider component, enable "Convex" and "Is Trigger" options
    • Optionally if you cloned all submodules, change the appearance of the powerup by selecting a new material element Mesh Renderer > Materials > ⦿. (Note that debug materials are not rendered in game view.)
  2. Create storage Assets/Prefabs.
    • In the Project window, right-click and select Create > Folder, and name it "Prefabs".
  3. Save the speedboost powerup as a prefab.
    • Drag the speedboost game object from the Hierarchy window to the Assets/Prefabs folder in the Project window. Et voilà, we created a new prefab.
    • Delete the peedboost game object from the Hierarchy.
  4. Set up powerup spawning.
    • Create an empty game object, name it "Spawner" and attach the Spawner.cs to it.
    • Select the Spawner object, which has a Spawner script attached to it.
    • Drag the speedboost prefab onto the field "Speedboost Prefab" of the Spawner script in the Inspector.
    • Now open Spawner.cs and uncomment the lineInstantiate(speedboostPrefab, ...).
  5. Save your file changes and your scene changes, and play the game.
