How To Utilize An Observer In Minecraft

How To Utilize An Observer In Minecraft:

Even though the main gameplay of Minecraft Survival Mode or Creative Mode isn’t too complicated, using functional Redstone blocks like the Observer opens up a whole new world of complexity and endless ways to be creative.

What Is Observer:

As its name suggests, the Observer “observes,” which is clear from the way its face looks both serious and a little bit cute. But it can be hard to understand what this block does in general and how it relates to other blocks, especially if you are new to Redstone mechanics.

There are many ways to explain how the Observer works, but one simple way is to compare it to the “if-then” statement used in programming.

How Does An Observer Work:

If you know anything about programming, you’ll know that a “if-then statement” is a way for a program to check a condition. For example, if a user presses the “Settings” button, the program will take them to the “Options” screen.

In the same way, the Observer in Minecraft looks at changes in the direction its “face” is facing in a way that is familiar. If it sees a change, it will send a Redstone signal to the block or space behind it.

For example, we put a torch in front of the face of an Observer. It “saw” that something had changed in front of it, so it sent a signal to the Redstone Lamp behind it.

Putting blocks in front of an Observer by hand is just one change that this Redstone block can notice. Using the simple “if-then” logic of this block, Minecraft players have made clocks, traps, flying machines, automated farms, and a lot more.

Remember that the Observer in the Bedrock Edition and the Observer in the Java Edition have small differences in what the block could do. Still, it works mostly the same in terms of how the Redstone reacts to changes it sees.

Putting Together A Recipe For The Observer:

In Minecraft Survival, you need three things to make an Observer: 6 Cobblestone, 2 Redstone Dust, and 1 Nether Quartz. Cobblestone is very easy to find, and Redstone blocks are likely to be found while you are naturally exploring caves & mines.

But if you want Nether Quartz, you’ll need to use Obsidian to make a Nether Portal and go into the underworld realm to look for it.

Amazing Idea For A Trap To Build With Observer:

Using an observer and Redstone, you can make a device in Minecraft that drops splash potions on a player when a diamond block is mined. We used both the Splash Potion of Poison as well as the Splash Potion of Harming in this design.

What You’ll Need:

  1. 4 Dispensers
  2. 1 Observer
  3. 33 Oak Planks
  4. 7 Redstone Dust
  5. 1 Diamond Block
  6. 3 Splash Potions that Hurt (Instant Damage II)
  7. 1 Potion of Poison to Splash (Poison II)

How To Make A Trap:

We put a diamond block in front of an observer & built an oak wall around it as part of our design for a potion trap. Then, we put dispensers on top of the diamond block, each with a splash potion in it.

When The Trap Goes Off:

When a player mines the diamond block, the observer would then notice that the block has changed, which means that the diamond block has been removed, and will drop splash potions on the player. This should give the player the status effects of both Poisoned and Instant Damage.

Observers On Java & Bedrock Are Different:

In Minecraft Java & Bedrock, the things that make a block update are different. So, the observer in each edition can see things that the other might not. Let’s talk about some of the most important ones.

Create A Crop Harvester:

One of the easiest ways to use the observer is to harvest crops automatically. When an observer sees that a crop is growing, it can use a piston to automatically break it. Follow these steps to make a simple sugarcane harvester that works on its own in Minecraft.

First, put a block of water next to a block of dirt and a block of sugar cane. Then, put a block right behind the piston and next to the sugar cane. This piston needs to be at least 2 blocks larger than the sugar cane and ought to be facing it.

To put the piston at a height of two blocks, you must utilize temporary blocks. Then, put an observer right on top of the piston. It should be facing the sugar cane. Then, put Redstone dust on top of the block right behind piston.

Now, when the sugar cane grows to the height of the observer, this should send a signal to the piston. The piston will move, causing the sugar cane to break and start growing again. If you have a hopper, it can even pick up the broken pieces of sugar cane.

In Minecraft, How Far Could An Observer See?

An observer can only tell when a block next to it changes, but not when a block farther away changes.

Are Observers To Blame For Lag?

When there are a lot of observers, it can slow down the game. But this doesn’t happen very often on Minecraft farms.
