Phase script allows players to go into the ground

I’m having a problem in a phasing script I made where if the player phases forward into the ground they can glitch into the map, I know why it’s happening because it’s just setting the players position. Is there anything I can utilize that if there’s something within the 15 blocks that it moves forward that it makes the player only move to the edge of it?

 game.ReplicatedStorage.Events.Phase.OnServerEvent:Connect(function(plr)
    	if game.Workspace:FindFirstChild(plr.Name) then
    		if plr.CanPhase.Value == true then
    			plr.CanPhase.Value = false
    			game.Workspace:FindFirstChild(plr.Name).Head.CFrame = game.Workspace:FindFirstChild(plr.Name).Head.CFrame + (game.Workspace:FindFirstChild(plr.Name).Head.CFrame.LookVector * Vector3.new(15,0,15))
    			wait(15)
    			plr.CanPhase.Value = true
    		end
    	end
    end)

I couldn’t fully grasp your question but if your looking for something that sets their cframe forward then

plr.Character.HumanoidRootPart.CFrame = plr.Character.HumanoidRootPart.CFrame + (plr.Character.HumanoidRootPart.CFrame.LookVector * 15)  + (Character.HumanoidRootPart.CFrame.RightVector * 15)
