How do I ignore multiple parts with Raycasting?

Asked by

Okay so the basic code from the roblox wiki

            local ray = Ray.new(player.Lightning.WorldPosition.WorldPosition,player.HumanoidRootPart.CFrame.lookVector.unit*100)
local Part,Position = game.Workspace:FindPartOnRayWithIgnoreList(Ray,{player,game.Workspace.Noncollide})

I'm trying to make the raycast ignore a folder in workspace called "Noncollide" but the output says this "21:51:30.115 - Unable to cast Dictionary to Ray".

Does anyone know how to make the ray ignore multiple parts?

you make `ray` but then you use `Ray` in the method? creeperhunter76 554 — 7y

Oh that was a mistake, i meant to put ray as in lowercase. Witchest 48 — 7y

Firstly, you defined the Ray as ray, and then used Ray in the FindPartOnRayWithIgnoreList function.

Secondly,you gotta define the ignore list using the GetChildren function on workspace.Noncollide.

local ray = Ray.new(player.Lightning.WorldPosition.WorldPosition,player.HumanoidRootPart.CFrame.lookVector.unit*100)

local ignore = workspace.Noncollide:GetChildren();
table.insert(ignore,player)

local Part,Position = game.Workspace:FindPartOnRayWithIgnoreList(ray,ignore)
