Ethereal Engine Pong

Gameplay

  1. When one or more players enters a goal then play is started
  2. When all players leave all goals then play stops
  3. If a ball hits a player goal then that player takes damage; at maximum damage the game ends
  4. volleying is automatic

Code

The game objects are arranged like so and there can be any number of players:

  pong
    goal
      paddle
      paddle
      plate
      score

A pong game is started when a player is on any plate, and ended when there are no players on any plates While the game is started balls are volleyed in order to each player When a plate is hit more than 9 times a game ends

Todo / Issues [minor]

  • ball is moved by a dispatch, this is not elegant, there's a bug where server implicit change doesn't network
  • discovery of parts could be done at startup only; minor but could improve
  • clients don't need to do full discovery of all part relationships; minor
  • only server needs to delegate authority; minor
  • don't let avatars own more than one set of paddles; minor
  • move entire TextComponent feature out of pong into etherealengine as a general reasource
  • and also fetch font more directly; rather than from 3js github repo

Features to consider later

  • perhaps some win effect?
  • optionally a robot player?
  • different shaped volumes
  • obstacles
  • gravity, attractors, fans etc
  • nicer paddle art
  • nicer table art

behave graph variant todo

  • ontick ball launcher x ? some kind of bug with trying to set forces on the ball -> looks like broken code in the engine

    • if game started test -> we could have a game reset pad
    • periodically launch the ball
  • plate collider

    • if it is a ball -> then increase damage -> reset ball
      • if damage is greater than 9 then end game
    • if it is an avatar -> if game is stopped then start game
  • if ball hit ground -> reset ball
