How do I make parts not obstruct the camera?

Help and Feedback Scripting Support
#1

I am making a top-down game where the camera is a few studs behind the top of the player.

. However, when sometimes when I am moving, my character gets obstructed by an obstacle. (Example, the character is behind a tree).

How would I make any object between the camera and the player become half transparent? (So the player could see their character).

Add this function to your code and run it to check if a part is blocking cam.

local oldPart = nil

local function checkIfPartInfront(cam, hrp) -------------- cam is the camera of the player and hrp is the humanoidrootpart of the player\
    local dir = (cam.CFrame.Position - hrp.Position).Unit * (cam.CFrame.Position - hrp.Position).Magnitude
    local result = workspace:Raycast(cam.CFrame.Position, dir)
    if result then
        local instance = result.Instance
        if instance:IsDescendantOf(hrp.Parent) then
            print("No part is blocking cam")
            oldPart.Transparency = 0
            oldPart = nil
        else
            print("part is blocking cam")
            instance.Transparency = 0.7 -------- adjust this 1 is transparent 0 is not transparent
            oldPart = instance
        end
    end
end

coroutine.wrap(function()
    while wait() do
        checkIfPartInfront(workspace.CurrentCamera, game.Players.LocalPlayer.Character:WaitForChild('HumanoidRootPart'))
    end
end

You can use Invisicam to get the effect you want
You can find it under StarterPlayer

Yes!
I read something on the dev hub that was talking about this. It’s a really cool inbuilt feature and i’m glad that it exists!
Basically, if a part is in front of a player, it will turn the part’s transparency down so you can see the player.

This only seems to work if I comment out my top-down script. (Probably because I change the camera type to ‘scriptable’.)

It doesn’t seem to work, although there are no errors either.

You can use get parts obscuring target,

There’s some example code in the devhub

Is it in a local script? Also I forgot to call the coroutine. This should do the trick:

local oldPart = nil

local function checkIfPartInfront(cam, hrp) -------------- cam is the camera of the player and hrp is the humanoidrootpart of the player\
    local dir = (cam.CFrame.Position - hrp.Position).Unit * (cam.CFrame.Position - hrp.Position).Magnitude
    local result = workspace:Raycast(cam.CFrame.Position, dir)
    if result then
        local instance = result.Instance
        if instance:IsDescendantOf(hrp.Parent) then
            print("No part is blocking cam")
            oldPart.Transparency = 0
            oldPart = nil
        else
            print("part is blocking cam")
            instance.Transparency = 0.7 -------- adjust this 1 is transparent 0 is not transparent
            oldPart = instance
        end
    end
end

coroutine.wrap(function()
    while wait() do
        checkIfPartInfront(workspace.CurrentCamera, game.Players.LocalPlayer.Character:WaitForChild('HumanoidRootPart'))
    end
end()
