Editing Tutorials

This hopefully growing collection of basic tutorials will help to build farms and build projects in VoxeLibre. Some tutorials were developed in a development environment with minimal changes in the code, e.g. by making the zombies slightly taller.

===Stalker farm===
Stalkers spawn only naturally, there are no spawner for stalkers, as other mobs (e.g. skeletons and zombies). But stalkers are the only source for gunpowder, needed to make rockets. As soon players have looted an Elytria, giving them wings to fly, they need rockets. And therefore, the need for a gunpowder farm is obvious.

Planning before start helps to avoid errors during the build of a farm. Some aspects to consider:
We want only stalkers, but ideally no zombies and no spiders. On youtube, there are a lot of tutorials for a creeper farm, mostly with the use of snowmen. But tests have shown, that we don't need snowmen in VoxeLibre. They make the build more complex but don't really add to the amount of gunpowder produced. Stalkers are quite small, so they can move within a 2-block box with additional carpet on the floor and trapdoor on the ceiling. In 0.89.1, zombies can no longer spawn in this same space, as the collisionbox of zombies was slightly changed, making them minimally taller.

This build was proposed by Nicu and verified by cyberonkel. The design is simple: four platforms build with full blocks are divided by 2 block wide water channels. On the platforms, carpets on the corners and in form of a grid, leaving 2 blocks between the carpets free avoid spider spawns. The ceiling is covered in closed trapdoors. This makes enough space for stalkers to spawn and move, but avoid the spawn of Zombies.

The water channels are 7 blocks long, water sources are hidden in the wall to avoid stalkers to sit on the water source. The water of the four channels stop in the center, building a 2x2 center hole, falling about 20 blocks deep to the kill zone, made from soul fires over hoppers, collecting the gun powder into a chest. Put signs two blocks below water level at the walls to avoid falling water into the kill zone.

===Iron farm===
Iron is a resources quite hard to collect by mining. As it is used in many recipes, many players will want to build an iron farm early in the game. The main source for iron outside of mining or collecting iron bars and nuggets from chests in villages or by a [[Portal]]
are Iron Golems. They spawn in villages, when villagers are attacked by hostile mobs.

====Early Game====
There are many models of iron farms working nicely. Some use resources found only later in the game, some can be build early with simple materials. VorTechnix as written a good tutorial for iron farms in early gameplay, available as [[Media:Early_Game_Iron_Farm_by_VorTechnix.pdf|pdf file]].

Iron Golems spawn in a sphere of 21 blocks around a villager, if there at least two other villagers in this sphere, and if there is a hostile mob in that cube and if there is a spawn point (≥1 block under an <code>air</code> block which is from <code>group:water</code> OR is <code>diggable</code>).

====Advanced design====
A proven design with a high yield is to build a hollow tower with e.g. stone wall blocks, resulting in a 1.5 block wide hole. Start at ground level (or water level and build at least 12 levels high, to make sure, that Iron Golems will spawn only on top of the tower. Put a sign on the interior side of the wall 2 level below the top and add 1 level of water above that sign. Iron Golems will spawn on this water block and fall down.

Build this wall tower deep into the ground – you will dig a hole of 3x3 to be able to place the walls. Place a chest at the lowest point, about 24 blocks below the water block in the tower (or about 12 blocks below ground level). Place a hopper above the chest. Assure, that the wall of the tower is made of non flammable blocks (as e.g. stone). Put 1 level of <code>lava</code> on top of the hopper.

To let spawn the Iron Golems, put 3 villager in a glass box about 15 blocks over ground (3 levels above the tower). Put a boat in another box 3 blocks away and lure a zombie into that boat. He will jump in the boat and stay there. Name him with a name tag and cover him from direct sun light.

As soon as the Zombie sees the villagers, he will try to attack them – resulting in the spawn of three Iron Golems (as we have three villagers). They spawn on the water block and will fall immediately down to the kill zone. To finalize, you will put <code>carpet</code> on all blocks of the villager and zombie boxes and on additional glas blocks around the tower. Don't forget to put a copper rod on top of the villager box to avoid their transformation into witches by lightning.

===Hoppers===
To connect a hopper, place a block on the opposite side of the direction you would like to send items. For example, if you wish to send items down, place a block above where the hopper would be, place the hopper and then the container beneath. On the other hand if you wish for the hopper to send items side way, place a block, say on the left of the hopper, place the hopper and then the container to the right of the hopper. With sideways, you can also use the screwdriver, but this does not work for vertical alignments. 

Another trick might be to Shift+Click the item you wish the hopper to connect to.
