Public Instance Methods

update() click to toggle source

Updating position is not necessary thanks to the velocity trait. In case the bullet is out of bounds, it gets destroyed and explosion particles are spawned.

# File lib/prkwars/bullet.rb, line 31
def update
  return if in_bounds(self, @gamespace)

  2.times do
    ExplosionParticle.create(@gamespace,
                             x: @x, y: @y,
                             zorder: ZOrder::GAMEOBJECT)
    destroy!
  end
