I can't get Raycast to not harm a teammate?

I made a unit shoot a ray but I want a way to make it not harm a team member or ally. I've tried if part.Parent.TeamColor == Unit.TeamColor and if part.Parent.TeamColor.Value == Unit.TeamColor.Value TeamColor is a BrickColor Value and I'm not sure what to do. (in the hierarchy, this is correct)

FindPartOnRay() returns the Part it found, the Part's position, the surface normal at intersection (not needed much), and the Part's material. So, you can do this

--// Pre-define raycast function to find a player
local HitPart = CastRay()
if HitPart then
	local Player = game:GetService("Players"):GetPlayerFromCharacter(HitPart.Parent)
	if Player then
		if not(Player.TeamColor == Unit.TeamColor.Value) then
			TakeDamage(Player)
		end
	end
end

If that doesn't work, try using the cmdbar in Studio to find and print TeamColor in the gun.

local function DamagePlayer(hitPlayerId, player, damage)
	local hitPlayer = Players:GetPlayerByUserId(tonumber(hitPlayerId))
	if (hitPlayer.TeamColor == player.TeamColor and Configurations.FriendlyFire.Value) or hitPlayer.TeamColor ~= player.TeamColor then
		local humanoid = hitPlayer.Character:FindFirstChild('Humanoid')
		if humanoid then
			humanoid:TakeDamage(damage)
		end
	end
end

if the spawns are on workspace then do something like this

damage = 34
if hitPlayer.TeamColor == game.Workspace.Redspawn.BrickColor then
damage = 0 
end

redspawn is the name of the team spawn you dont want to take damage

little something i did earlier use this to get to your problem. if this helps vote me up and if it doesnt comment.
