I recently found a dungeon in Minecraft, and I have decided to make an XP farm out of it. From watching youtubers do it, I know that you need to have an 8x8 hole around the spawner to maximize spawning space. Since this is an even number and there is only one (1x1) spawner, the spawner cannot be in the center. How do I know what side to put it on? I know that it matters what side you put it on, I just don't remember how I can find out what side.
technically its the best to dig a 10x10 hole around the spawner, not a 8x8 because the spawner picks a block and then picks a 'pixel' (thats the best explenation I can come up with) of that block as middle for the mob. if that pixel happends to be so close to the wall that the mob can't fit in anymore, then the mob can't spawn.
many people don't know this. too many.
