[Temporacy Solved]How to detect the world position on the custom island?

[dinhkarate]

Like the title, I want to know how to detect the world position on the custom island I made in the modworldgenmain.lua.
I just want to spawn the chest on the island exactly in the middle of the heart. (in the picture)
Here is the picture. I'm glad if anyone can help me. Thank you for reading!!!

I don't know the answer to your question but I do think that island looks pretty.

There's a mod called Coordinate, might help you if that still works.

Did you use tiler to make the map? If you did, you can also add entities to your layout at the desired position.

@Cheggf Thank you a lot <3

@SomebodyRandom Thank you, I'm going to try it

@zaptrap Yes, I do use the titler to make the map. But I don't know how to detect the desired position. Could you help me?

Actually, now I still can't know how to detect it but the problem is solved.
Each turf it have its own 64x64. It is all I done when add a lot of chest to detect it. So I decide to try, try, and try. Yeah I hope other, who have this problem in future can solve.
