  1. What do you want to achieve?
    I want to create a water splash system !
  2. What is the issue?
    My code is not working properly !
  3. What solutions have you tried so far?
    I did this but I don’t think this is the best way to do it :
local Player = game.Players.LocalPlayer
local Character = Player.Character
local Humanoid = Character:WaitForChild("Humanoid")
local RootPart = Character:WaitForChild("HumanoidRootPart")
local RunService = game:GetService("RunService")
local TouchWater = false

RunService.Heartbeat:Connect(function()
	local BodyPos = Player.Character.HumanoidRootPart.CFrame
	local x, y, z = BodyPos.X, BodyPos.Y, BodyPos.Z

	local min, max = Vector3.new(x + 0.01, y + 0.01, z + 0.01), Vector3.new(x - 0.01, y - 0.01, z - 0.01)
	local region = Region3.new(max, min)
	region = region:ExpandToGrid(4)

	if region then
		local material = workspace.Terrain:ReadVoxels(region, 4)
		if material[1][1][1] == Enum.Material.Water then
			TouchWater = true
		else
			TouchWater = false
		end
	end
end)

Humanoid.StateChanged:Connect(function(oldState, newState)
	if newState == Enum.HumanoidStateType.Landed or oldState == Enum.HumanoidStateType.Freefall and newState == Enum.HumanoidStateType.Swimming or oldState == Enum.HumanoidStateType.Running and newState == Enum.HumanoidStateType.Swimming then
		if TouchWater == true then
			workspace.Part.ParticleEmitter.Enabled = true
			wait(1)
			workspace.Part.ParticleEmitter.Enabled = false
		end
	end
end)

while wait() do
	workspace.Part.CFrame = Player.Character.HumanoidRootPart.CFrame
end

‘My code isn’t working’ doesn’t tell us what exactly is happening.
Does the splash never happen? Happen late? Only happen in Studio but not in-game? Do you get any errors in the Output window?

When you have issues you should troubleshoot by putting print statements in each section of code to see where the problem is happening.

Why not put the ParticleEmitter directly in the player instead of dragging a Part along with them?

I’ve do this but it doesn’t work (the particle emmiter is set to enabled = false or true but we can’t see the particles!) :

local Player = game.Players.LocalPlayer
local Character = Player.Character
local Humanoid = Character:WaitForChild("Humanoid")
local RootPart = Character:WaitForChild("HumanoidRootPart")
local RunService = game:GetService("RunService")
local TouchWater = false
local Splash = false

RunService.Heartbeat:Connect(function()
	local BodyPos = Player.Character.HumanoidRootPart.CFrame
	local x, y, z = BodyPos.X, BodyPos.Y, BodyPos.Z

	local min, max = Vector3.new(x + 0.01, y + 0.01, z + 0.01), Vector3.new(x - 0.01, y - 0.01, z - 0.01)
	local region = Region3.new(max, min)
	region = region:ExpandToGrid(4)

	if region then
		local material = workspace.Terrain:ReadVoxels(region, 4)
		if material[1][1][1] == Enum.Material.Water then
			TouchWater = true
		else
			TouchWater = false
		end
	end
end)

Humanoid.StateChanged:Connect(function(oldState, newState)
	if newState == Enum.HumanoidStateType.Landed or oldState == Enum.HumanoidStateType.Freefall and newState == Enum.HumanoidStateType.Swimming or oldState == Enum.HumanoidStateType.Running and newState == Enum.HumanoidStateType.Swimming then
		if TouchWater == true then
			Splash = true
			print(Splash)
			wait(1)
			Splash = false
			print(Splash)
		end
	end
end)

spawn(function()
	if Splash == true then
		game.StarterPlayer.StarterCharacter.HumanoidRootPart.ParticleEmitter.Enabled = true
	else
		game.StarterPlayer.StarterCharacter.HumanoidRootPart.ParticleEmitter.Enabled = false
	end
end)

Try this:

		TouchWater = true
	else
		TouchWater = false
    end    
    print(TouchWater)

and

	if Splash == true then
		game.StarterPlayer.StarterCharacter.HumanoidRootPart.ParticleEmitter.Enabled = true
        print("Enabled true")
	else
		game.StarterPlayer.StarterCharacter.HumanoidRootPart.ParticleEmitter.Enabled = false
        print("Enabled false")
	end

Then see what happens in your Output window. That will tell you exactly where your problem is.

the code works and changes ParticleEmmiter.Enabled fine :

local Player = game.Players.LocalPlayer
local Character = Player.Character
local Humanoid = Character:WaitForChild("Humanoid")
local RootPart = Character:WaitForChild("HumanoidRootPart")
local RunService = game:GetService("RunService")
local TouchWater = false
local Splash = false

RunService.Heartbeat:Connect(function()
	local BodyPos = Player.Character.HumanoidRootPart.CFrame
	local x, y, z = BodyPos.X, BodyPos.Y, BodyPos.Z

	local min, max = Vector3.new(x + 0.01, y + 0.01, z + 0.01), Vector3.new(x - 0.01, y - 0.01, z - 0.01)
	local region = Region3.new(max, min)
	region = region:ExpandToGrid(4)

	if region then
		local material = workspace.Terrain:ReadVoxels(region, 4)
		if material[1][1][1] == Enum.Material.Water then
			TouchWater = true
		else
			TouchWater = false
		end
	end
end)

Humanoid.StateChanged:Connect(function(oldState, newState)
	if newState == Enum.HumanoidStateType.Landed or oldState == Enum.HumanoidStateType.Freefall and newState == Enum.HumanoidStateType.Swimming or oldState == Enum.HumanoidStateType.Running and newState == Enum.HumanoidStateType.Swimming then
		if TouchWater == true then
			Splash = true
			wait(1)
			Splash = false
		end
	end
end)

spawn(function()
	while wait() do
		if Splash == true then
			game.StarterPlayer.StarterCharacter.HumanoidRootPart.ParticleEmitter.Enabled = true
		else
			game.StarterPlayer.StarterCharacter.HumanoidRootPart.ParticleEmitter.Enabled = false
		end
	end
end)

When you test it and look inside ‘FireStrykerAzul’ in the workspace do you have the ParticleEmitter in your HumanoidRootPart?

Yes there is but the enabled value does not change ! :hushed:

When spawn(function)) is called why is there a while wait() do statement. If spawn is called every time the task scheduler is updated isn’t this irrelevant? I haven’t used it before so I’m just guessing.
Also, when the Heartbeat function is called and TouchWater is changed back to false won’t that cause the if TouchWater == true in the next function to fire again, changing Splash back to false almost instantly, which would cause the spawn function to turn Enabled back to false instantly too?
That’s why I asked you to put a print statement in the last function so you can see the time between when Enabled is turned to true then back to false to give you that information.

In Spawn((function)), you need an infinite loop because it’s just to do multiple infinite loops at the same time. :grinning:
And I did what you told me it works perfectly, enabled = true we wait 1 sec then enabled = false.
The real problem is that I have a starting character and enabled is well defined but if we go to the player the Particle Emmiters.Enabled are not defined … :thinking:
