About this project
What does In borders add?
Fight. Survive.
In this datapack, you will have to fight while the borders keep shrinking regularly. You can't even trust the floor, it'll turn into lava eventually!
How to play:
First time you join, you will spawn on a platform. Wait for atleast 2 players, then you can get ready by typing "/trigger ready set 1". Or, if you are already ready, you can type "/trigger ready set 0" to get unready. When everyone is ready, the game starts. Every single player is spread through the map. You will have to grind materials, defend yourself, attack others and move before the borders catch on. Eventually, borders will stop shrinking lava will start to rise from the deeps. You will have to tower up and fight in the skies. Be the last one alive to win!
Details
- you can't fight on the starting platform.
- you can also start instantly by typing "/scoreboard players set start1 start 1". requires operator access.

While creating a world, go to "More" tab. Click on "Datapacks". Then, click on "Open pack folder" and add the datapack in the folder.

First reset the server's world files if the world is ever loaded. Second, create a folder named "datapacks" if it doesn't exist already. upload the datapack to the folder.
Updates
this datapack was mainly made for version 1.21.11. but the datapack works on versions from 1.21.6 to the newest version (I hope).
there will be regular updates and you can contact me at emretmekvar@gmail.com and maybe I can update the datapack to your version. Or, if the version you play has bugs, you can contact me and I will do a bugfix!
