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
