`Geometry.CreateSphere()` should get its own class?

[valkyrienyanko]

I was thinking of doing something like

var sphere = Sphere.Create(); // or could be cube
sphere.SetColor(Colors.Blue).SetSize(0.5f).DeleteLater(2);

zombies/Scripts/Autoloads/Geometry.cs

Lines 9 to 28 in 3a2d8ee

	public static void CreateSphere(Vector3 pos, float radius = 0.2f, float removeDelay = -1)
	{
	var sphere = new MeshInstance3D();
	sphere.Mesh = new SphereMesh();
	var sphereMesh = (SphereMesh)sphere.Mesh;
	sphereMesh.Radius = radius;
	sphereMesh.Height = sphereMesh.Radius * 2;
	sphere.Position = pos;
	if (removeDelay != -1)
	{
	var timer = SceneTree.CreateTimer(removeDelay);
	timer.Timeout += () => sphere.QueueFree();
	}
	SceneTree.Root.AddChild(sphere);
	}
