I would like to find a block's coordinates from within the block's own class. Is there a way to do this?

 

 

u can use asm to make the blocks that u want coord extends BlockContainer, inser the unimplemented Methods(by asm), create a tile entity and get the cords by the tile entity

You mean the in-world coordinates of a block? I don't know how to do that if already game-existing block which is everywhere like grass or stone but you can easily to that with a block which is not self-generating in world. You can override onBlockAdded() method and add them some code which saving the coord of placed block to a static list (and remove it with breakBlock()). You could also to that with self-generating block but it would have to use just onNeighborBlockChange() or... I don't know. Maybe edit structure-generating files?
