With a render distance of whatever hometown is (5?), how close do I have to be for my...
1. Nether portals to spawn pigmen?
2. Villages to spawn golems?
3. Ocean monument to spawn guardians?
4. Pistons to be activated with a redstone timer?
5. Sugar cane to grow?
6. Cows to become adults?
7. Wheat to grow?
8. Melons to grow?
9. Cacti to grow?
10. Hoppers to move items?
11. Hopper minecart to move and gather items?
12. Villagers to harvest my crops?
13. Pumpkins to grow?
14. Villagers to become adults?
15. Chickens to lay eggs?
16. Guardians to despawn
17. Zombie spawner to spawn zombies?


I want to know the minimum and maximum distances I can be from each.
