I have been "researching" the mob spawner blocks for a while, and how they come in with world generation. (by researching I mean reading minecraft wiki and watching extensive videos describing world generation)I have found that 1. You can push a certain array of cobblestone blocks into an unloaded chunk for a spawner. 2. You can manipulate how many mossy cobblestone blocks are generated3. Based off mossy cobble generation, you can determine what type of spawner it is. I have also found a design for an infinite piston pusher. If you are wondering what it is called, it is Dan's (from zipkrowd) cobra. You can make up to 8 spawners in a single chunk. Now, I can understand all of you thinking "This is way OP it should be illigal!" However, I have done this in my survival world, and it is NOT fun. It requires 4-5 stacks of redstone blocks and 4-5 stacks of pistons. The best way to get redstone is from a witch farm. It also takes a LOOONG time to build and figure out all the redstone. There are no world downloads to see how it works, so I had to figure it out myself. I am personally pondering on wether this should be allowed. It is like iron farms... It is not an intended feature, but it is not exploiting a GLITCH. I personally feel that iron farms should be banned if this technique is banned, as they have the same intent. What do you guys think? Should I post the video showing how this works?
