Hi. Are you tired of those anti-zombie designs that do not keep the zombies away from your door or trap the NPCs too? Well, no more. I have created a simple design that will keep the zombies away from you while keeping your NPCs safe. Meet... The Ultimate Anti-zombie Device, or TUAD. There is also an alternate design where the block above my mouse can be one block above, unfortunately I couldn't take any pictures of it. This simple design is enough to keep the zombies away from your house. Allow me to explain: The NPCs' AI and the zombies' are different when it comes to jumping. The fighter AI jumps as soon as it sees a gap, while the NPCs will only jump when they have a wall in front of them. Allow me to explain with an image: The red line shows the path of a fighter AI, like the zombie's. The green line shows a NPC's This simple device is pretty modular and versatile do to it's simplicity and can easily be changed to kill the zombies and gather their loot, take them to a arena or even trap them in a cage. I do have to warn you, though, that it will only work if the zombie is walking until the pit. If it is jumping or anything this device will not work. This device will also not work with platforms, as the zombies ARE able to jump down them if you're bellow them. Thanks for reading, please give feedback.
