In the procedure editor, under "World Data", there are three bits, "Get current world spawn coordinate". Under "Entity Procedures", there's a block: "Move provided entity to x: y: z:". Put the world spawn coordinates in the x, y, and z slots. There you go! If you wanted player spawn point, I can't find it. Sorry!
