Nimrod Engine Ideas & Goals

Key

using - template which essentially "from EXPR import nil" + some selection
part - macro which defines a part of the app/game (corresponds, by name, to editor data)
mode - built-in part state system component (multi-state. easy transition declaration)
on - app/game event logic (can be user-defined in editor)

Simple Person Part Example

Note: both name and age can be initialized by an editor or setup file.

using Console: write

part Person:
  var
    name: string,
    age: int
  on start:
    write("Hi, my name is $name.")
    write("I am $age years old.")

Space Ship Example

using Parts, Space, Timer
using Keyboard: Keys

part Ship:
  const
    speed = 4.3
  var
    space = Space.random(World.bounds)
    model = Model.load("ships/XWing.mdl")
    lasers = list[Laser].new(dynamic, reserve:50)
  
  on update:
    if Keyboard.key(A).isHeld: space.moveLeft(speed)
    if Keyboard.key(D).isHeld: space.moveRight(speed)
    if Keyboard.key(W).isHeld: space.moveForward(speed)
    if Keyboard.key(S).isHeld: space.moveBackward(speed)
    
    if Keyboard.key(Space).isPressed: lasers += Laser
  
  on model.collide: die


part Ship.Laser:
  const
    speed = 24.8
  var
    space: Space
    timer: Timer
  
  on start:
    space = base.model.nextFireSpot
    timer = Timer.start(10, Seconds)
  
  on update:
    if timer.isDone:
      base.lasers -= this
    else:
      space.moveForward(speed)

Light with Modes Example

using App.Panel
using UI.Buttons

part Light:
  var
    isOn = false
    brightness = 0.0
    button = Panel.find(Button, "ClickMe")
  
  proc turnOn() =
    mode = On
  
  proc turnOff() =
    mode = Off
  
  mode On:
    goal 2, Seconds:
      isOn = hold true
      brightness = blend 1.0
  
  mode Off:
    goal 2, Seconds:
      isOn = hold false
      brightness = blend 0.0
  
  on button.click:
    mode.toggle()


on setup:
  # global setup
  spawn Light
