Above are the 2 co ords for 2 zombie spawners I have managed to link up with water columns and pathways etc[/p]
Is there anyway to activate both at the same time and get maximum yeald??
Since you need to be within 16 blocks of a spawner to activate it the maximum distance between two is 32 blocks, or slightly less than one block more than the distance. The exact midpoint is (415, 29, 85.5); note that I added 0.5 to the coordinates since the distance is from the center of the block (the calculation above also works with whole block coordinates since the offset is constant):
This will place you 15.54 blocks away from each spawner with a margin of about half a block (the player is 0.6 blocks wide so if you stand in the northwest corner of block 415, 85 you'll be centered at 415.3, 85.3, which is still within range of both spawners and doesn't require looking at F3 for proper positioning each time).
Thanks that’s great information sadly that is unintentionally the exact drop point I made the 2 streams go to and it takes a lot of work to move it’s ok I have made a 12 block rail cart to AFK in in between the 2 spawners that slowly goes between the 2 giving them both enough activation time and send more than enough zombies to my killing chamber
