I need help. What height do Floating Islands spawn?
Do I just need to have a gravity potion to access them or do I not have any in my world?
Solution 1:
Each world size has a floating island, although the height it's set to differs from the size of the world.
The Small map size has a maximum of 4 islands, and the approximate height for them are 250 - 600 ft. (125 - 300 tiles)
The Medium map size has a maximum of 7 islands, and the approximate height for them are 450 - 800 ft. (225 - 400 tiles)
The Large map size has a maximum of 8 islands, and the approximate height for them are 650 - 1000 ft. (325 - 500 tiles)
