How to quickly track position of frame in relation to other frames

[NinjoOnline]

I want to be able to keep track of the ‘bullets’ position, and check if it has hit any of the objects on screen. However I fear having a number of these objects could create issues where it might no always detect the hit in time.

local function Shoot()
	if ShootDebounce then return end
	
	ShootDebounce = true
	
	local NewBullet = Bullet:Clone()
	NewBullet.Position = UDim2.new(0, Ship.Position.X.Offset, 0, Ship.AbsolutePosition.Y)
	
	NewBullet.Parent = Bullets
	
	coroutine.wrap(function()
		local ObjectHit = false
		while true do
			if ObjectHit then break end -- Object has been hit
			
			if NewBullet.AbsolutePosition.Y <= -NewBullet.AbsoluteSize.Y then break end -- Off screen
			
			NewBullet.Position = UDim2.new(0, NewBullet.Position.X.Offset, 0, NewBullet.Position.Y.Offset - BULLET_SPEED)
			
			-- Check if bullet has hit an object
			for _, v in pairs(Objectives:GetChildren()) do
			
			end
			
			wait()
		end
		
		NewBullet:Destroy()
	end)()
	
	wait(BULLET_WAIT)
	
	ShootDebounce = false
end
