Level 35 : Artisan Architect

This building map displays various command block tools, and redstone devices, that will allow you to enhance the weather mechanics of your build, and make it more realistic. Using the tools provided, you will be able to reenact the water cycle system in the Minecraft; it adds features such as; runoff of water creating cascade on the cliffsides, when rain falls; snowmelt of mountain; changing landscape of mountain.

There are several water cycle features that are displayed in this build. By combining all of the displayed features, you will be able to reenact the water cycle system in Minecraft world. The following features are:

  • Formation of cascade formed by the run off of rain water, while it rains, and when rain stops, the cascade disappears.
  • Changes in water level due to weather.
  • Overflow of lake creating new water falls/ making existing water falls bigger, when it rains.
  • Flooding of lake and river, when it rains.
  • Snow melting on the mountain top, forming stream of water, and build up of snow when it snow (rainy day in cold biome).
  • Tornado in the plain and desert biome in gloomy day (rainy day in desert biome). Tornado is made with particles, so it is visible only in close distant. It is a working tornado that will destruct nearby structures, lift up mobs and player, and give nauseating effects when player rides tornado.
You can recreate water cycle and make your build more dynamic by combining all of these features:

Build a mountain, where when it snows, the snow and ice are formed, and when a its clear day, the snow and ice melts, creating streams of water which run off, and are collected in the lake. When this occurs, you could change and raise the water level of lake to show the increase in water volume due to the extra water from the snowmelt. When water level rise, you can form water fall, or make the existing water fall bigger, which flows into river (make sure you elevate the river, and make it sloping down to the ocean, and make sure it is not in same water level as ocean for most parts). From river, water will exit into the ocean. Make sure you also raise the water level of the rivers and lakes when it rains. Add couple cascades on the cliff side when it rains, or right after when snow melt, for more dynamic looks.

Rain Detector

Rain detector is the redstone device that detects rain. It differentiates the rainy days from clear days; sending according signals to activate the desirable water cycle features. For example in rainy day, it will activate cascade on cliff side, and when the day is clear, it will send a signal to activate snowmelt on the mountain top.

Rain Sensor/ Rain detecting Device

Rain sensor is composed of three components; rain detector, signal converter, and executing components. Rain detector differentiate clear day from rainy day. Signal converter converts long continuous signal into one short signal, like the signal that is created from the push of a button. Executing components consists of command blocks and other redstone tools which allows various mechanics from happening, which replicates the weather features; for example, by sending a command which replaces stone that is blocking waterway into air, and allow water to flow out, it will make it look as if cascade waterfall has been formed.


Rain sensor device that can be copied as schematic and be used in your map is included. instructions on how to use is included in the build. read the signs and the books inside the chest for instruction.
there are two devices, one using command blocks (I advise you to turn off the chat when you decide to use this one), and one without command block.

Three command mechanics are included in the rain sensor device that can be copied and used:

  • Changing stone into air during rainy day, air into stone in clear day; for cascade waterfall effects.
  • Changing water into air in the clear day, and air into water in rainy day; for cascade waterfall effects.
  • Changing water into air, and vice versa, but with large coverage; for flooding effects and water level changes.

How to apply command mechanics into your build:

  1. Get armor stand and name tag from chest.
  2. left click armor stand with name tag to name armor stand, as if naming mob. Although it doesn't show the name on the screen, because armor stand is considered entity too, so you can name it, and you can display command effects at armor stand, or at position relative to the the armor stand.
  3. Place the armor stand three blocks below, where you want the effects from happening.

Detailed Account On Rain Detector

There are three versions of rain sensor. First version is my original design, third version is replica of someone else's design. All three designs uses the mechanics of the daylight detector to detect rainy days; when it rains, both day, and inverted daylight detectors are activated. This means, if its possible to make the device that only activates when both day and inverted day light sensors are activated, it would be possible to differentiate rainy day from clear day. This can be easily accomplished by creating the gates that are connected to both detectors, where the redstone signal has to pass through; so unless both detectors are activated and both gates are opened the signal would not pass through. However, the dimness of the light during the dawn and the dusk of the clear day is same as the dimness of the rainy day. So there is a need to differentiate the rainy day from dawn and dusk; to solve this problem, I delayed the signal between first and second gates to outlast the dawn and husk; so unless gates are continually opened for long period of time, the signal will not pass through. After building my first design, I later realized that the strength of the daylight detectors are different throughout the day (I turned off the weather cycle while I was building it, so I figured this out late). So I incorporated this information to make the second design. One significant problem I have with this method of differentiating rain is that, it cannot detect rain during the night time. So to accommodate this, I linked the copper rod to this this device, so at least during the thunder storm, the device will be activated during night as well.
The benefit of third design is; it is more compact, takes less blocks, and space, so it's easier to hide. Also, it is made with the blocks that are easier to harvest from the wild in the survival mod. However, there are benefits of first design as well; with first design, because it has some delays to the activation, in my opinion, it looks more realistic, since cascade, and overflow of water doesn't occur right away when it rains. It takes time for water to accumulate to form these occurrence. The benefit of second design is, it is easier to understand the mechanics of the device, and easy to replicate.
