Most of the fights that take place in Minecraft are very close together. TNT's guns can be deployed in large groups, but they require intensive use of your resources, capable of emptying your entire inventory quickly. So what's the best way to stop the army trying to break into your defense? A machine gun!
Steps
Step 1. Gather all your resources
You will need 6 blocks, 1 distributor, 3 'redstone', 4 'redstone' torches, a lever and ammo.
Step 2. Place your distributor
Place a redstone unit adjacent to the distributor and two blocks adjacent to the redstone unit in a straight line, as shown in the image.
Step 3. Place two blocks, respectively top left and right of the two existing blocks, as shown in the image
Step 4. Place the torches on the outer sides of the two blocks resting on the ground, as shown in the image
Step 5. Place the two remaining redstone dust units on the top side of the two blocks resting on the ground, as shown in the image
They should start blinking.
