I tried another method. I built a dispenser block - a block that can store objects and be triggered to eject them – and filled it with arrows. I connected it to a pressure plate, so that stepping on the plate would cause an arrow to shoot out. This was also a flawed method for quite a few reasons. It takes multiple arrows to kill a single beast, so creatures were only injured by my trap and were then allowed to continue their reign of terror. Secondly, I was burning through stacks of arrows at a ridiculous pace. And thirdly, I found myself the target of my trap far more often than I expected. Every time I would check on how well it was doing, I would somehow manage to get shot in the face with one of my own arrows.
So I decided to embark on a very large construction project. I traveled a good distance away from my home base and built a new tiny house. Around this house, I began building a series of canals, which all drained into a basin similar to my original water trap. Inside the basin, I planted rows upon rows of cacti, which will damage anything that touches them. I built a drainage tunnel at one end of the basin, which would collect any items dropped by mobs that were unfortunate enough to get caught in my trap, yet was too small for any monsters to squeeze through. So mobs would get caught in one of my canals, drift toward the cactus farm, and be damaged on the spiky cacti. Whatever items they dropped would flow into my drainage tunnel, where I could collect them without harm.
There is only one problem with such a method: in order for this canal system to be effective, it must be absolutely massive. I ended up spending days upon days constructing this thing, building a series of canals that stretched for miles in every direction. I spent my days building this thing, and my nights waiting patiently in the drainage tunnel, collecting whatever items would flow in my direction.
Of course, these are only a few examples of the sorts of traps you can build in Minecraft. If you can figure out how to use redstone triggers and relays, the possibilities are almost endless. You can build pitfalls triggered by flowing water, stacks of buried TNT triggered by pressure plates, and even lava flows that unexpectedly drop from ceilings. If you are a creative person, you can spend hundreds of hours building and perfecting deadly traps.
Be warned: the more creative you are, the more of your free time will be consumed by Minecraft's trap-building tools in your pursuit of the perfect method to dispose of creepers and other such monstrosities.
