# The Idea
\nWindy Days attempts to improve transportation, specifically regarding the Elytra while still not forcing the changes upon the player. What this means is that if you don’t wish to take part in the systems of the datapack, you could just fly under the wind-affected atmosphere (y159 or below).
\n## Wind
\nIn real life, the direction of the wind changes constantly, however this system only has the wind change directions daily, choosing from 5 different wind-states (it can choose the same one multiple times in a row)
\n– North
\n– South
\n– East
\n– West
\n– Still (no wind movement)
\n## Examples
\nThe following are some examples in which Windy Days comes into play.
\n### Example 1
\nYou want to go North, towards your friend’s base, luckily the wind is also going North! This means you should fly as high as safely possible to be boosted by the wind to get to your friend faster.
\n### Example 2
\nYou want to go East, away from your enemy, however, the wind is going West! This means you should fly as low as safely possible to be less affected by the wind, as trying to fly against the wind won’t work at all.
\n### Example 3
\nYou want to South, towards your base, but the wind is going West. This means you will have to slightly East to balance yourself, otherwise, you’ll be put off course.
\n#
\n**DISCLAIMER:** These systems are in **no** way 1:1 to real science. I traded the idea of realism for fun, and I think that was a good idea.
\n# Layers
\n### Troposphere
\nIn the Troposphere you’ll notice a slight pull depending on the wind, otherwise, there aren’t many particles or other things to note.
\n### Stratosphere
\nIn the Stratosphere the wind-dependent pull will increase drastically and particles will start to pick up.
\n### Mesosphere
\nIn the Mesosphere, things will start to switch up. While the wind will of course drastically increase, you’ll also start taking damage unless you have Water Breathing, this is due to the lack of oxygen. (This effect will also apply to any higher layers.)
\n### Thermosphere
\nIn the Thermosphere, combined with the lack of oxygen and drastic wind increase, you will also begin to burn due to the extreme temperatures. This is the fastest and most dangerous layer.
\n### Exosphere
\nUnlike the previous layers, the Exosphere has no directional influence, it will still lack oxygen, but instead of burning, you’ll begin to freeze.
\n### Deadzone
\nYou shouldn’t really go up here but the Deadzone will disable your Elytra and going too far into it will instantly kill you. (1100+)
\n## Y Values:
\n“`
\nTroposphere = 160-327
\nStratosphere = 328-495
\nMesosphere = 496-663
\nThermosphere = 664-899
\nExosphere = 900-999
\nDeadzone = 1000+
\n“`
\n# Dependencies
\nThis datapack *requires* Apoli or alternatively Origins to function.
\n# Suggested Mods
\nI suggest you install Do a Barrel Roll for a more interesting flying experience. I also recommend that you install Celestial and use the “Overworld Orbit Demo” to make it look like you’re actually leaving the atmosphere!
