Noisteroids

• The classic game of Asteroids with the weapon system of Noita

Gameplay

Basic loop

• Each level has a certain number of enemies (asteroids, eventually enemy ships) that must be destroyed
• Once all enemies are cleared, the player is prompted to upgrade their ship
• After upgrading, the next level begins
• Incremental gameplay, more enemies, different (more resiliant) enemies, complex enemies, "boss" rounds every X levels

Movement

• It's asteroids
• Should the movement be upgradable? Maybe in future

Firing system

• The ship has one "firing system" (more in future?)
• The firing system is a list (the "deck") of "modules", which have two types:
  • Weapons
    • These are the actual projectiles that will end up damaging enemies
  • Modifiers
    • These modify the first weapon found after itself with some effect (e.g. a deck like: module -> module -> weapon, would have both modules modify the weapon)
• Each of these modules has base stats
  • Shared
    • Delay (how much time is applied before the next weapon fires)
  • Weapon specific
    • Speed
    • Damage
    • Lifetime (how long it lasts before expiring)
    • Spread (how accurate is it)
    • Radius (optional: if the weapon is AOE)
• When the user press "shoot", starting at the beginning of the deck:
  • Calculate the total delay by parsing the whole deck, and apply it before the next shot is taken
  • If the current module is a weapon
    • Apply any modifiers that have been encountered, in order
    • Fire the weapon, sending the remainder of the deck with it
    • When that weapon expires (Lifetime) or makes contact, continue executing the deck from it's location
  • If the current module is a modifier
    • Track it's effect, go next

Examples

• Let's say the following weapons and modifiers exist with some non-specific stats:
  • Weapons
    • Laser
      • Delay: short
      • Speed: fast
      • Damage: medium
      • Lifetime: short
      • Spread: small
      • Radius: none
    • Rocket
      • Delay: long
      • Speed: slow
      • Damage: high
      • Lifetime: long
      • Spread: medium
      • Radius: medium
    • Lightning
      • Delay: very short
      • Speed: very fast
      • Damage: high
      • Lifetime: very short
      • Spread: high
      • Radius: none
  • Modifiers
    • Double shot
      • Delay: short
      • Effect: the weapon fires 2 parallel projectiles
    • Double scatter
      • Delay: short
      • Effect: the weapon fires 2 projectiles in a spread pattern
    • Pentagon formation
      • Delay: medium
      • Effect: the weapon fires 5 projectiles is a pentagon pattern
• Lets go through what happens with some example dekcs when the player presses shoot
  • Laser -> Laser -> Rocket
    • A laser comes out of the players ship, with a small random deviation from the direction the ship is pointed
    • When the laser hits an enemy or expires, another laser is fired with a small random deviation from the direction of the first laser
    • When that laser hits an enemy or expires, a rocket is fired with a medium random deviation from the direction of the second laser
    • When that rocket hits an enemy or expires, because it has a radius, and explosion with the given radius
  • Double scatter -> Laser -> Pentagon formation -> Rocket
    • 2 lasers come out of the players ship in a spread pattern
    • When either of those lasers hit an enemy or expire, 5 rockets are shot in a pentagon formation

RANDOM STUFF

• We should consider adding a bullet time thing while the player is live-editing their modules
