Simplified version of Gamestate with ticks, used by both client and server - every tick the server sends new Gamestate to connected clients

local state = Class {}

function state:init()
	self.tick = 0 -- this tick is used by jitter buffer to figure out which state is newer
	self.entities = {}
end

function state:paddleAttack(paddleId)
	-- server calls this method when player performs an attack with laser
end

function state:paddleMove(paddleId, direction)
	-- server calls this method when player moves up or down
end

function state:update(dt)
	self.tick = self.tick + 1 -- every update call increase tick value

	-- process entity list, update state of all entities (simplified)
	for _, entity in ipairs(entities) do entity:update(dt) end
