What would be the right way to use mouse hover?

Asked 176 views1 answers

So i have this grid placement system. I've made it putting a hover script inside EACH BRICK IN THE GRID but it lags the game too much. So i would like to know if its possible to do a multiple hover detector with a few scripts

Movement system: Moves block around if it is not placed yet

local ZPosition = script.Parent.Position.Z
local XPosition = script.Parent.Position.X
local YPosition = script.Parent.Position.Y + 1.019
local Vector = Vector3.new(XPosition, YPosition, ZPosition)

script.Parent.ClickDetector.MouseHoverEnter:connect(function(Player)
   workspace.Lava.Position = Vector
end)

Placement script: Places block

script.Parent.ClickDetector.MouseClick:Connect(function()
	workspace.Lava.Transparency = 0
	workspace.Lava.CanCollide = true
end)

Move cancellator script: Cancels movement if block is placed

workspace.Lava.Changed:Connect(function()
  if workspace.Lava.Transparency == 0 then
  	  script.Parent.Move.Disabled = true
  end
end)

Please have in mind there's the three scripts in EVERY block in the grid. So the game lags

You do realise you could have a ClickDetector in a Model, so you could have all the parts in a model and the click detector would work on the model

but how would it detect each individual hover over each individual brick?

Do you know how to use Remotes? You can make this way more efficient using them

You can have one script that handles all the grid's blocks.

Disregard my last comment, found it difficult to explain how you can use remote events so I came up with another idea.

First, you need to gather all the blocks by inserting them into a table:

local GridModel = workspace.GridModel
local BlockName = "GridBlock" -- name of the grid's blocks

local GridBlocks = {}

function getGridBlocks()
	if GridModel then 
		for i, v in pairs(GridModel:GetChildren()) do 
			if v.Name == BlockName then 
				local block = v
				table.insert(GridBlocks, block)
			end
		end
	end
end
getGridBlocks()

--Once you have all the grid blocks, you can get each block's click detector and do the same thing:

local ClickDetectors = {}

function getDetectors()
	if #GridBlocks >= 1 then 
		for i, v in pairs(GridBlocks) do 
			if v.Name == BlockName then 
				local clickDetector = v:FindFirstChild("ClickDetector") or Instance.new("ClickDetector", v)
				table.insert(ClickDetectors, clickDetector)
			end
		end
	end
end
getDetectors()

--Now that you have all click detectors, you can apply the events:

--Use a loop to gather the detectors:
for i, v in pairs(ClickDetectors) do 
	if v:IsA("ClickDetector") then 
		local detector = v
		detector.MouseHoverEnter:connect(function(player)
			--code
		end)
		detector.MouseClick:connect(function()
			--code
		end)
	end
end

Now you won't need three scripts for every block, just a ClickDetector

looks awesome! but this pops up in the output: "Workspace.Script:37: attempt to call method 'GetChildren' (a nil value)"

Oh mb. Try removing the ':GetChildren()' and leave 'ClickDetectors'
