As you probably know, the last update brought us mechanisms in sandbox. I know that not many people know exactly how they work, so I made a tutorial to help people understand mechanisms and to help them build epic stuff! Enjoy :) First of all, you should learn how the Signal works. Every mechanism has it's own power value from 0 to 10. Singal lose 1 power point per 1 block, which means normally it can go through 10 blocks max before reaching a value of 0. If turned on, Sources always have a power value of 10. All the components and devices except the inventor (which always has 10) have power values of 0 unless a signal is delivered to them. Usually components pass signal further and devices keep it. Every device needs at least 1 power value to run, and there's no difference if it's on 1 or 10. To see the power value of a mechanism block you can turn on debug mode in sandbox by using "/g_debug 1" command in console, "/g_debug 0" to turn it off. It looks like this: Spoiler: with out debug: Spoiler: with debug: First let's explain: COMPONENTS they are bassicaly blocks used for passing signal and often modifing it somehow. WIRE: Most basic component, passes signal both ways. Single button/lever etc. signal can go through 10 of these. Spoiler: wire ANKLE: Curved version of wire. Spoiler: ankle TEE: Another version of wire that can link 3 wires. Spoiler: tee JUNCTION: Can link 4 wires Spoiler: junction gif DIODE: Works like wire except it passes signal only one way. Spoiler: diode gif RESISTOR: Halfs the power of signal. Works only one way. Spoiler: resistor debug TRANSISTOR: Stops the signal from 2 sides unless it's powered. Works both ways. Spoiler: resistor gif TOGGLE: Works as lever. If it recive signal once it will keep sending signal until reciving signal again. Works one way. Spoiler: toggle gif OSCILLATOR: Repeats the signal until it's powered. Works one way. Spoiler: oscillator gif INVENTOR: Keeps sending signal one way, unless it recives signal. You can use 2 of them in a row to make signal go further than 10 blocks. Spoiler: signal extender gif RANDOMIZER: Randomly stops signal. Works one way. Spoiler: toggle gif Now: SOURCES Blocks that create power! LEVER: Activated with E. Keeps sending signal until turned off. BUTTON: Activated with E. Sends signal for around second. COINS SLOT: Work as button except it needs 60 coins to activate. PRESSURE PLATE: Activated when putted pressure by player/bot/item. MOTION SENSOR: Actived by any moving object. Last but most fun DEVICES the coolest part of mechanisms LAMP It lights! (if powered) Spoiler: lamp gif MAGAZINE Stores items/arrows. Used with dispenser and bolter Spoiler: magazine Does anyone really needs image of a magazine? BOLTER: Device that when powered shoots any kind of arrows. Needs magazine with arrows to work next to it. (it doesn't shoot ballista bots :| ) Spoiler: bolter gif DISPENSER: Throws out items when powered. Spoiler: dispenser gif RECEIVER & EMITTER These two blocks pass signal without wire if put opposite each other in maximum lenght of 18 blocks Spoiler: wireless gif SPIKER Ejects spike when powered. Deals 1 heart damage. Spoiler: spikers gif OBSTRUCTOR If powered, works liek solid block. If not, works as background. Spoiler: obstructor gif Well, that's all for that tutorial. I hope I helped you somehow. Thx to Jasioloza for helping me a lot! May the science be with you!
