The camera passes through objects

Hello everyone. Faced a problem when the player’s camera passes through walls. Please help me fix this

RunService.RenderStepped:Connect(function()
local isFirstPerson = (camera.CFrame.Position - head.Position).Magnitude < 1.6

if isFirstPerson then
	humanoid.CameraOffset = Vector3.new(0,0,-1)
else
	humanoid.CameraOffset = Vector3.new(0,0,0)
end

for _, v in character:GetChildren() do
	if v:IsA("BasePart") and v ~= head then
		v.LocalTransparencyModifier = 0
	end
end

end)

Here is the script

The problem is that you are offsetting the camera to at the front of the player’s head so collisions won’t prevent the camera from clipping into the surface. To avoid this you are going to have to push the camera backwards a little bit, precisely the Camera’s NearPlaneZ + some marginal distance away from the head collision box. So something like this:

if isFirstPerson then
	humanoid.CameraOffset = Vector3.new(0,0,-1 + camera.NearPlaneZ + 0.1)

Note: having the hardcoded 1 offset might break this for differing head collision box sizes.
Another option would be to just make the head collision box larger if you want to maintain the effect of having the camera in front of the character.

If I do this, then the player’s body will not be visible
