Try it with emojis 😀
public class Test
{
public static void main(String[] args)
{
System.out.println("Hello. How are you?");
java.util.Scanner cin = new java.util.Scanner(System.in);
String in = cin.nextLine();
System.out.println("I feel "+in+" too.");
}
}
Recently I have been learning about the Entity-Component-System architecture for video game programming. I think it will help out with my “World’s Tiniest RTS” game. I learned about it here, in Robert Nystrom’s Game Programming Patterns. I also heard on the Exploding Rabbit podcast how Jay Pavlina (of Super Mario Bros. Crossover fame) uses the pattern. Here is my Clojure code for it, currently:
(defn create-game []
{:entities {}})
(defn create-entity []
[(java.util.UUID/randomUUID)
{}])
(defn add-entity [game entity]
(update-in game [:entities] conj entity))
(defn add-component [game entity com data]
(assoc-in game [:entities (first entity) com] data))
;;example
(let [e1 (create-entity)]
(->
(create-game)
(add-entity e1)
(add-component e1 :position [3 4])
(add-component e1 :name "ball")))
