As of 1.8, too many Powered Rails on a track may increase the Player to a speed at which they will derail if they go around a bend, introducing the necessity for a slowdown time. Unpowered Powered Rails can be used as brakes, as they will quickly completely stop Minecarts that hit them. Powered Rails will launch different types of Minecarts different distances depending on the amount of stuff they're holding. Minecraft Name Generator - you can generate 30 random names (usernames/nicknames) used on Minecraft, which is a sandbox video game created by Swedish game. Powered Rails cannot be curved like Rails, which limits their usefulness. It was added as a response to the minecart booster bug, which was fixed with the release of Beta 1.6. I’ll cover one such setup in next week’s post.Powered Rails are a block that can decrease or increase speed of moving Minecarts, which they will do if provided with a Redstone signal. If, on the other hand, you want to be able to dump tons of items into a chest and let the item transport system regulate itself, you’re going to need a somewhat more advanced setup. The system won’t produce at a time more items than your minecart can hold. In many situations where you have a system producing items (a reed farm, for example), this won’t be a problem. Because the input from the comparator next to the loading hopper will never turn off, the falling edge circuit will never pulse to send the minecart away. So, for example, if the minecart you’re using to transport items is a hopper cart versus a chest cart, you wouldn’t want to place six stacks of items into a chest above the loading hopper, since only five of those stacks will successfully load onto the hopper cart, leaving a stack of items inside the hopper. The main thing you have to make sure you don’t do is load more into the loading hopper than your minecart can hold. This pulse is long enough to power a powered rail and send a cart away. When the lever is turned off, the Redstone lamp will pulse on for just a moment then turn back off. And it will only pulse, not stay on, as would happen with a NOT gate (i.e., a Redstone torch). So if I am using a lever as the input for a falling edge circuit, the output will pulse only when I turn the lever off after having also turned it on. A falling edge circuit sends an output pulse when an input pulse ends. This requires a special Redstone circuit called a “falling edge” circuit. Instead, we want the cart to go on its merry way once items have finished passing through the hopper. But obviously we don’t want the rail powered as soon as items enter into the loading hopper. So what we have to do is have our minecart sitting on a “depowered” powered rail (to keep it stationary) and detect the contents of a hopper that is loading items onto the minecart with a comparator. Maybe I’ll post about this in the future once I have some idea of how reliable it is. Then another sticky piston pulls back, letting the cart drop onto another set of tracks. This setup detects when a minecart is full then uses a sticky piston to push the minecart over one block. Once the hopper finishes transferring items from the minecart into a nearby inventory, the powered rail is once again powered, sending the minecart back where it came from. A comparator reads if anything is in the hopper and, so long as there is, depowers the powered rail over the hopper (thereby keeping the minecart still until it is empty). The way this is done is by placing a powered rail at the end of a track over a hopper. Of the two functions of minecart-based item transfer (loading and unloading the minecart), unloading the minecart is by far the easier. Unloading Minecarts (Then Sending Them Back When Empty) Today, I want to cover two simple Redstone devices that you can use to unload and load minecarts automatically. With the MC 1.5 Redstone update, all of a sudden it became possible to load items into and out of minecarts automatically using hoppers and comparators. Back in the day (classic Tekkit and some time afterwards), if people used minecarts to transfer items it was pretty much only via additions provided with the Railcraft mod. While many mods add item transfer mechanics into the game (pipes, tubes, conduits, conveyor belts, etc.), vanilla Minecraft actually has had item transfer systems built in for a long time in the form of minecarts. It uses Redstone powered automatic loading and unloading systems that I’ll show you in this post.
