Tweening Transparency on a touch

Number 1. Sorry :grimacing:

  1. It says "Unable to cast to Array "
#43

Yeah, sorry, never used this before. Let me research more on it.

#44

well thats simple, its because the array isnt defined, so in XRay(script.Parent.PrimaryPart) add another parameter which is an empty table: XRay(script.Parent.PrimaryPart, {})
and also the first parameter should be around an array, so it should look like this:
XRay({script.Parent.PrimaryPart}, {})

#45

Yeah, as @mroaan said


local function XRay(castPoints, ignoreList)
	ignoreList = ignoreList or {}
	local parts = workspace.CurrentCamera:GetPartsObscuringTarget(castPoints, ignoreList)

	for _, part in pairs(parts) do
		part.LocalTransparencyModifier = 0.75
		for _, child in pairs(part:GetChildren()) do
			if child:IsA("Decal") or child:IsA("Texture") then
				child.LocalTransparencyModifier = 0.75
			end
		end
	end
end

while task.wait(0.3) do
XRay(script.Parent.PrimaryPart,{script.Parent})
end

Sorry lul
Also the previous script hid the player character too. Fixed that.

Still says it cant cast a ray for some reason

#49

the first parameter needs to be inside an array, just like in the documentation:

XRay({script.Parent.PrimaryPart})

edit: ignoring the player’s character isnt really necessary since when you get in first person all your body parts disappears

#50

Also put it in a loop so it always checks instead of once on startup.

#51

Also by the edit, wdym, the game is a top-down view game-?

not necessarily when you get in first person, since its a top-down view game you pretty much dont need to ignore the player’s character.

#54

im not sure whats wrong in the video…

I have made a code:

I cast a ray from the humanoid root part to the camera part, If there is a roof the transparency is set to 0.8

local hrp = script.Parent.HumanoidRootPart

local cameraPart = Instance.new("Part")
cameraPart.Transparency = 1
cameraPart.CanCollide = false
cameraPart.Parent = workspace
cameraPart.Name = "cameraPart"

cameraPart.CFrame = CFrame.new(hrp.Position + Vector3.new(0, 40, 0), hrp.Position)

local bp = Instance.new("BodyPosition")
bp.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
bp.Parent = cameraPart

wait(1)

while wait() do
	local StartP = game.Workspace.cameraPart.Position
	local EndP = script.Parent.HumanoidRootPart.Position + Vector3.new(0,3,0)
	
	local result = workspace:Raycast(StartP, EndP - StartP)
	
	if result then
		if result.Instance.Name == "Roof" then
			result.Instance.Transparency = 0.8
		end
	end
	
	bp.Position = hrp.Position + Vector3.new(0, 50, 0)
end
