My spray doesn't work properly

Help and Feedback Scripting Support
#1

Hello. I’m making a spray tool that lets you spray decals on walls, but it doesn’t work as expected. I want it to spray decals on every surface, and properly. Currently, I am using ray-casting to achieve this. Thank you for any help, I really appreciate it. Thank you, again.
Please help if you can :slight_smile:

Here’s my code:

local player = game:GetService("Players").LocalPlayer

local mouse = player:GetMouse()

local wallDetector = script.Parent:WaitForChild("WallDetector")

local sprayPaint = script.Parent

local function ray_Cast(a, b, params, debugMode)
	local rayResult = game:GetService("Workspace"):Raycast(a, b, params)
	
	if (rayResult) then
		return rayResult
	else
		return nil;
	end
end


sprayPaint.Activated:Connect(function()
	
	local params = RaycastParams.new();
	
	params.FilterType = Enum.RaycastFilterType.Blacklist
	
	params.FilterDescendantsInstances = {player.Character, sprayPaint}
	
	local a = wallDetector.Position;
	
	local b = wallDetector.Position + (wallDetector.CFrame.LookVector * 0.1);
	
	local result = ray_Cast(a, b, params, true)
	
	if not (result) then return end
	
	local decal = game:GetService("ReplicatedStorage").Decal:Clone();
	
	local decalPart = Instance.new("Part");
	
	decal.Parent = decalPart
	
	decal.Face = Enum.NormalId.Front
	
	decalPart.Anchored = true
	
	decalPart.CanCollide = false
	
	decalPart.Size = Vector3.new(1, 1, 1)
	
	decalPart.CFrame = CFrame.new(result.Position + (decalPart.Size/2))
	
	decalPart.Parent = workspace
	
	decalPart.Transparency = 1;
	
	decalPart.Parent = workspace
	
end)
